We will be delighted to coordinate a technician’s visit to your area.

The main advantage is the direct relationship: the product goes from the factory to your home. The Proftex team consists of highly qualified specialists who handle the entire cycle: technical measurement, feasibility study, quote preparation, and certified professional installation.

In most cases, the renovation is completed in a single day. Since we manufacture every window to measure and deliver it fully finished, the process at home is agile: we remove the old frame, fix the new structure, and perform the hermetic sealing immediately.

Our windows require very low maintenance. For the profiles, periodic cleaning using a soft cloth and neutral soap is sufficient. To ensure the smoothness of the mechanisms, we recommend applying a drop of oil to the fittings and gears once a year.

Although white remains the favorite for its versatility, at Proftex we have an almost unlimited color range. We use high-resistance foiling techniques for PVC and advanced lacquering for aluminum, adapting to any decorative style.

Absolutely. Our bicolor system allows you to comply with the facade aesthetics of your community of neighbors while customizing the interior of your house with the tone that best combines with your decoration.

No. The quality of a Proftex window differs in its internal structure, the quality of the raw materials, and the precision of the assembly. Each unit is manufactured on demand, making it a unique piece designed to resist and insulate efficiently.

To ensure stability and security, we introduce a galvanized steel core inside all our profiles. This prevents deformations over time and guarantees that the window maintains its robustness throughout its entire service life.

These are high-efficiency systems that combine multi-chamber profiles and technical glass. At Proftex, we develop enclosures that meet the Passivhaus standard, achieving such high energy savings that the window “works” for you to maintain the ideal climate.

It is the guarantee that our products comply with the safety and technical directives of the European Union. At Proftex, the CE Marking vouches that every door or window has been rigorously evaluated before going to market, complying with all legal requirements of the Member States.

Thanks to the durability of our materials, a well-maintained window can last for decades. Under normal conditions of use, the resistance of high-quality PVC means that its renovation will not be necessary for many, many years.

Yes, we are committed to sustainability. PVC is a 100% recyclable material. At the end of its useful life, all components of a Proftex window (glass, metal, and polymer) can be separated and reused in new industrial processes.

Absolutely not. We use premium PVC formulations resistant to UV radiation. Unlike low-quality materials, Proftex profiles maintain their original shine and color despite intense exposure to the sun.

Technical Doubts

1. Aluminum vs. PVC: Which is the Smarter Investment?

When comparing products of similar price and performance, Proftex PVC systems stand out as the superior choice. Their main advantage is radical energy efficiency: by preventing the thermal leaks common in less insulating materials, you can reduce your home’s energy consumption by up to 76% (savings calculated based on direct losses through window openings).

It is a matter of basic physics: aluminum is a metal and, therefore, a natural conductor. This means it transmits the cold or heat from the outside directly into your living room. At Proftex, we know this leads to:

  • Increased Bills: Your climate control systems must work twice as hard.
  • Loss of Comfort: Cold spots near windows.
  • Condensation: The frame “sweats” to the touch.

Even aluminum with a Thermal Break (RPT) struggles to match the natural insulation of a certified quality PVC profile. In any circumstance, PVC is a far more effective insulator.

That annoying dripping on the inside of frames occurs when warm air from the house touches a very cold surface. Since aluminum is a conductive material, it cools down rapidly to the exterior temperature, causing ambient humidity to turn into liquid. With Proftex PVC, this problem disappears. As a poor conductor, the profile maintains a stable, warm temperature on the inside, preventing puddles on the floor or moisture stains on the walls.

The peace and quiet of your home depends on airtightness. At Proftex, we combine three key factors to silence the outside world:

  • Hermetic Sealing: We use state-of-the-art hardware and gaskets.
  • Material Elasticity: PVC absorbs sound waves more efficiently than rigid metals.

Glass Configuration: We recommend high-performance glazing for maximum acoustic attenuation.

It is common to hear myths regarding the toxicity of PVC, but the reality is quite different. Today, this material is essential in products requiring maximum health safety, such as baby bottles, hospital IV bags, and drinking water pipes. During the polymerization process, any unstable components are transformed into an inert, harmless material that is completely safe for your family’s health.

Our windows do not require expensive treatments or repainting. To keep them looking like the first day, you only need:

  • Cleaning: Regular washing with water and neutral soap.
  • Mechanics: Lubricate the hardware and moving parts twice a year to ensure smooth and precise operation.

Definitely. Your home’s location determines the type of window you need:

  • Coastal Areas: Proftex PVC is immune to salt corrosion and sea spray, making it ideal for beachfront properties.
  • Large Cities: If you live in a high-traffic area, the combination of our profiles with acoustic glass will provide the rest you need.
  • Security: In areas where protection is a priority, we integrate advanced anti-theft systems to turn your home into a fortress.

Acoustic Insulation

1. If I increase the thickness of the air chamber, will I have less noise?

Not necessarily. It is a common misconception that a wider air gap stops sound better. In reality, noise protection depends primarily on the thickness and composition of the glass panes, not the space between them. At Proftex, we recommend combining glass of different thicknesses (for example, one 6mm and one 4mm). This asymmetry allows each pane to block different sound frequencies, creating a much more effective barrier against external noise.

Generally, sound intensity decreases with distance, but this is not always the case in urban environments. In buildings, a sound channeling phenomenon often occurs: traffic noise can be heard more clearly on high floors than on lower ones, because sound bounces off opposing facades and hits your windows directly. Therefore, even on a 10th floor, high-quality enclosures are essential.

While it might seem like the ideal goal, “zero noise” is not always comfortable. For context, a library environment is around 30 dB. If we completely eliminate external sound, the human ear becomes so sensitive that you would start noticing internal noises—pipes, appliances, or even your own heartbeat—that previously went unnoticed. At Proftex, we seek the perfect balance so your home feels like an oasis of peace without losing a sense of naturalness.

Eliminating these noise sources 100% is technically almost impossible because they emit vibrations at very diverse and high frequencies. However, with the right equipment, Proftex can reduce these loud noises to levels equivalent to a light traffic murmur, making life near railway or airport infrastructure perfectly comfortable and relaxed.

Thermal Insulation

1. What does Thermal Transmittance (U-Value) represent?

In the window and door industry, we use the U-Value to measure how much energy (whether cold or heat) escapes through a surface. At Proftex, our goal is to offer you the lowest possible U-Value: the lower this figure, the greater the insulating capacity of your window and, consequently, the higher the savings on your energy bills.

Thermal insulation is, essentially, the resistance a material offers to the flow of temperature. Not all components behave the same way in different climates; therefore, at Proftex, we meticulously select low-conductivity materials that act as a real barrier between the outdoors and your indoor comfort.

Condensation occurs when warm, humid indoor air comes into contact with a cold surface. Since PVC is a natural insulator, Proftex profiles maintain a balanced surface temperature, avoiding the “thermal shock” that creates water droplets. When combined with low-E (low-emissivity) double or triple glazing, the risk of moisture is drastically reduced.

To refresh the air without cooling down the walls of your home, the ideal method is quick cross-ventilation. Opening opposite windows for just 10 minutes is enough time to purify the environment while maintaining the room’s thermal inertia.

Proper air renewal is vital to avoid a stale environment and excess humidity caused by airtightness. We recommend ventilating all rooms in the morning for about 30 minutes. At Proftex, our windows can incorporate micro-ventilation systems or integrated vents, allowing your home to “breathe” in a controlled and safe manner.

Absolutely, yes. A low-quality roller shutter box can be the largest source of air and noise leaks in the entire facade. This is why at Proftex, we install fully integrated and thermally certified boxes. For a perfect seal, we recommend shutter motorization, which eliminates the hole for the conventional strap—usually the weakest point where comfort escapes.

Glass & Glazing

1. What is the actual function of the air chamber?

The air chamber acts as a thermal buffer. By installing double or triple glazing, we create a sealed space that physically separates the glass exposed to the elements from the interior glass. This separation breaks the direct transmission of temperature, ensuring that your home’s climate remains stable regardless of what is happening outside.

Maximum efficiency is generally reached with chambers between 12 mm and 16 mm. It is important to note that “more” is not always “better”: if the chamber exceeds 16 mm, convection currents (air movements) can be generated inside, which ultimately compromise the thermal insulation. At Proftex, we calculate the exact composition based on the dimensions and the type of glass chosen.

There is no universal “best glass,” but rather an optimal solution for each specific case. The choice depends on whether your priority is heating savings, protection against traffic noise, or impact security. At Proftex, we provide a personalized diagnosis to recommend the configuration that best fits your home.

This is glass treated with a high-tech microscopic layer that functions as a “thermal mirror.” Its mission is to reflect heat back into the interior of the home during winter, preventing it from escaping. Proftex’s Low-E glass drastically reduces thermal transmittance (U-Value), turning your windows into an active barrier that improves overall energy efficiency.

To name a glazing unit, we follow a logical order: Exterior Glass + Air Chamber + Interior Glass. For example, a standard configuration of 4mm + 12mm + 4mm indicates two 4 mm glass panes separated by a 12 mm air space.

Triple glazing is the peak performance option. By adding a third pane and a second chamber, we multiply the thermal insulation capacity and solar control. It is the recommended choice for climates with extreme temperatures or homes seeking the most demanding energy-saving standards. Its specifications would look like this, for example: 4+12+4+12+4.

Argon gas is an invisible insulator that is much heavier than air. By replacing the air in the chamber with this inert gas, we significantly improve the thermal capacity of the unit. It is a completely safe, colorless, and non-toxic solution that enhances comfort without affecting visibility, ensuring the heat stays exactly where you want it.

Security

1. What is the real difference between laminated and tempered glass?

Although both are considered safety glasses, they protect you in different ways:

  • Tempered Glass: In the event of a break, it disintegrates into thousands of tiny, blunt fragments, preventing deep cuts. It is highly resistant to both thermal and mechanical impacts.
  • Laminated Glass: It is composed of two or more glass sheets joined by an internal layer of polyvinyl butyral (PVB). If the glass receives a heavy blow, the pieces remain adhered to this elastic layer instead of shattering outward. Due to its ability to resist intentional attacks, it is the essential component in Proftex’s high-security systems.

The PVC used in the manufacturing of our windows is a highly safe material. According to the UNE 23727 standard, it is classified as M1, which means it is difficult to ignite and is self-extinguishing. In case of a fire, Proftex PVC does not propagate flames: if there is no direct and constant heat source acting on it, it stops burning naturally, helping to contain the fire.

The difference is critical, especially in ground-floor homes or easily accessible areas. At Proftex, we raise the standard of protection through three pillars:

  • Reinforced Hardware: We install systems with “mushroom” bolts and steel strikers in the frame that lock the closure and prevent the window from being forced open by prying.
  • Anti-theft Glazing: We incorporate laminated glass with high impact resistance.
  • Extra Components: We offer the possibility of adding keyed handles or advanced locking systems.

We move beyond a window that simply closes to an enclosure system designed specifically to deter and resist any attempted intrusion.

Savings

1. Which is the most cost-effective option?

If you are looking for the best ratio between initial investment and performance, PVC has no rival. For an aluminum window to reach similar insulation levels, it would need to incorporate highly advanced Thermal Break (RPT) technology, which would raise its price significantly above PVC without necessarily outperforming it.

At Proftex, we guarantee that our PVC windows offer superior energy efficiency compared to any aluminum option of an equivalent price. Replacing old windows with Proftex systems can reduce energy losses by up to 76% (*), optimizing your budget from day one.

Windows are typically the most critical thermal leakage points in a home. A window is efficient when it acts as a shield, maintaining a comfortable temperature without causing your electricity or gas bills to skyrocket.

By installing Proftex PVC systems, you not only minimize that 76% energy loss but also contribute to environmental sustainability and gain exceptional acoustic insulation. The secret lies in the combination of a high-quality multi-chamber profile and the appropriate technical glass.

You can identify a deficient window if you notice any of these signs:

  • Drafts: Do the curtains move even when the window is closed?
  • Thermal Transmission: Does the profile feel very cold in winter or hot to the touch in summer?
  • Condensation: Do water droplets or fog appear on the frames during cold days?
  • Excessive Spending: Do you need to keep the air conditioning or heating at maximum levels to stay comfortable?

If you answered “yes” to any of these questions, your windows are letting your money escape.

Yes, immediately. High-quality thermal insulation prevents the outside climate from altering your home’s temperature. This drastically reduces the use of climate control devices. Lower electricity consumption translates into lower bills. With Proftex, that reduction in energy loss of up to 76% guarantees direct and sustained financial relief.

Rather than a cost, it is a high-yield investment. The savings generated on monthly utility bills allow you to amortize the installation in just a few years. From that point on, all energy savings become a net benefit for you throughout the entire lifespan of the product. At Proftex, we design custom quotes where the level of performance translates into a real return on investment (ROI).

The fundamental difference is the nature of the material. Aluminum is a conductive metal; to prevent it from transmitting cold or heat, an insulator (Thermal Break) must be inserted, which makes the manufacturing process much more expensive.

PVC, conversely, is a natural insulator by itself. It does not need “add-ons” to resist temperature conduction. Therefore, if you are looking for maximum insulation at the best price, PVC will always be the most logical and economical choice over reinforced aluminum.

Both materials can reach a lifespan of 50 years with minimal maintenance. However, for homes in coastal areas, Proftex PVC has a critical advantage: it is immune to galvanic corrosion and sea spray.

While aluminum windows may show pitting or loss of aesthetic quality due to the marine environment, PVC maintains its integrity and original appearance for decades without degrading, making it the safest option for the coastline.

Design

1. What variety of options does Proftex offer for my windows?

At Proftex, we don’t believe in standard solutions. Our capacity for adaptation is total: from an infinite catalog of textures and reliefs to complex architectural shapes (arches, irregular, or circular windows). Furthermore, we master all opening systems: casement and tilt-and-turn, sliding, folding, lift-and-slide, and tilt-and-slide. Whatever your renovation project, we have the technical configuration that fits.

Absolutely not. It is a common myth that PVC finish options are limited. While white is a success due to its brightness, at Proftex we have a vast color range. We offer everything from textures that faithfully imitate wood for warm and rustic environments to a complete palette from the RAL color chart with modern and avant-garde finishes.

We design with total integration in mind. Thanks to our flexibility in finishes, Proftex systems adapt to any aesthetic:

  • Classic or Rustic Style: Wood finishes that provide warmth without the maintenance of real wood.
  • Minimalism and Avant-Garde: Monochromatic or metallic tones that enhance clean lines.

Our windows are the preferred choice for rehabilitations and renovations, as they respect the essence of the building while providing 21st-century technology.

Durability depends directly on the purity of the raw material. At Proftex, we only work with components that exceed the most demanding quality standards of the European market. By choosing a premium brand with proven certification, you ensure that your windows maintain their original shine and color against the intense solar radiation of our area, always backed by our product guarantee.

Absolutely. PVC is a 100% recyclable material. Furthermore, its carbon footprint during manufacturing is significantly lower than that of aluminum, as it requires less energy and generates fewer CO2 emissions. By drastically improving insulation, your Proftex windows reduce the need for climate control, making your house an environmentally responsible and sustainable home.

Changing windows is much simpler and cleaner than most people imagine. The Proftex process is designed for your convenience:

  • Technical Visit: We perform precision measurements and evaluate the best technical solution.
  • Mounting Options: Depending on the condition of the home, we can install the new units over existing frames (avoiding any masonry work) or perform a full replacement with a minimal and extremely careful intervention.

Our goal is that the increase in your comfort and efficiency is a fast, professional, and stress-free process.

Need and Benefits

1. When is the right time to replace your windows?

There are clear signs that your windows have reached the end of their lifecycle: if you feel drafts, notice condensation (fogging) between the glass panes, or feel that heat escapes quickly. Generally, if your windows are more than 15 years old, they lack the technology required for proper insulation. Replacing them isn’t just an aesthetic upgrade; it’s an investment in silence, thermal comfort, and monthly savings.

Installing high-efficiency windows thermally seals your home, eliminating “cold spots.” This guarantees a constant temperature throughout all seasons, protecting you from Alicante’s intense summer heat and damp winter cold. Additionally, acoustic insulation transforms your home into a peaceful space, drastically reducing traffic or street noise, with the potential to save up to 30% on your climate control bills.

Without a doubt. The savings are perceptible from the very first month. By installing top-tier profiles (such as our Veka, WDS, or Aluplast systems), energy leaks are prevented. This allows air conditioning and heating systems to run for shorter periods to maintain the same comfort level, translating directly into lower utility costs.

The difference compared to old carpentry is massive. A modern window with the right hardware (such as Roto systems) can be up to five times more thermally efficient. In terms of noise, quality glazing can reduce external acoustic pollution by up to 40 dB—essential if you live in busy urban areas or near main avenues.

Window Types, Materials, and Technical Features

1. Which is the best material for my windows: PVC, aluminum, or wood?

The choice depends on your priorities. PVC stands out for its unbeatable thermal and acoustic insulation, as well as being a cost-effective, zero-maintenance option. Aluminum is the preferred choice for avant-garde designs and large formats due to its high mechanical strength (always requiring a Thermal Break). Wood offers a noble aesthetic but demands constant care. We analyze your project to recommend the ideal solution.

To maximize insulation, casement and tilt-and-turn options are the most airtight. If space is limited, sliding windows are very functional, although their sealing level is slightly lower. We evaluate your home’s available space to optimize functionality.

It is a multifunctional system that allows two movements: a full side opening (like a conventional door) and a top-tilted opening for safe ventilation without fully opening the window. It is the perfect solution for maintaining airflow without compromising security or insulation.

A casement or “swing-out” window rotates on a side vertical axis. Its main benefit is the hermetic seal, which presses the rubber gaskets uniformly, guaranteeing maximum energy efficiency. Additionally, it makes cleaning the glass from the inside significantly easier.

Double glazing uses two panes of glass with an insulating air or gas (Argon) chamber and is sufficient for most homes. Triple glazing adds a third pane, creating two chambers. This is the premium option for extreme climates or areas with severe noise pollution where maximum energy savings are sought.

Low-E (Low-Emissivity) glass acts as a barrier that prevents heat from escaping in winter. Solar Control glass, conversely, reflects external radiation in summer, preventing the home from overheating without losing natural light.

Aluminum is a conductive metal. The Thermal Break (RPT) consists of inserting an insulating material (such as polyamide) between the internal and external faces of the profile. This “breaks” the transmission of temperature, preventing external cold or heat from entering and eliminating condensation on the frames.

We collaborate with market-leading brands to guarantee durability. For PVC and aluminum profiles, we use Veka, WDS, and Aluplast systems. Furthermore, we equip our windows with high-precision Roto hardware and Saxun solar protection solutions.

The winning combination is a high-end PVC profile paired with laminated acoustic and Low-E glazing. Correct installation and the use of quality hardware are fundamental to ensuring there are no air or noise leaks.

Aluminum is the ideal material for large glazed surfaces. Its rigidity allows for slimmer, more elegant profiles that support heavy glass without deforming, maintaining a minimalist and modern aesthetic.

Absolutely. We offer an extensive palette of RAL colors, metallic finishes, textured options, and foils that perfectly imitate the texture of natural wood.

Yes, thanks to the two-tone (bicolor) system. You can choose a tone that respects the building’s facade and another that perfectly matches your interior decor.

Our PVC systems (such as the Veka line) are self-extinguishing. The material contains additives that make it difficult to ignite; it does not propagate flames and goes out on its own as soon as the heat source is removed.

Installation

1. What is the estimated timeframe to complete the installation?

The duration of the assembly depends on the volume of windows, technical complexity, and accessibility of the home. For a medium-sized flat, our team usually completes the full replacement in just 24 to 48 hours, provided no complex masonry work is required. For villas or projects with large motorized windows, the time may be slightly extended to ensure a perfect fit.

While removing old frames and adjusting new profiles inevitably generates some dust and noise, it is a fast and minimally invasive process. Structural reforms are not necessary in most cases. Our technicians protect walkways and furniture and handle the removal of old materials to leave your home in perfect condition after the final sealing.

Yes, there is no problem with residents staying home. To minimize inconvenience, we work room by room, finishing one before moving to the next. We only recommend clearing access to the windows and covering dust-sensitive electronic equipment to facilitate the workers’ tasks.

Administrative management varies by property type and location:

  • Single-family homes: Generally, a prior notification to the town hall is sufficient, provided the building’s structure is not altered.
  • Communities of Neighbors: If the change affects the exterior aesthetics (color, shape, or divisions), it is mandatory to have the approval of the owners’ board to comply with the Horizontal Property Law.
  • Historic Centers: In specially protected areas in Alicante or surroundings, a specific urban planning authorization may be necessary.

Warranty and Maintenance

1. What type of warranties protect my investment?

When you renovate your enclosures, you have double support for total peace of mind:

  • Product Warranty: Profile and hardware manufacturers offer extensive coverage, often reaching 10 years or more against PVC discoloration or metal corrosion.

Installation Warranty: As installers, we guarantee that the sealing, leveling, and operation of the window are optimal. This usually covers the first 2 to 5 years, ensuring that thermal and acoustic insulation remains intact.

In Spain, quality is regulated by strict controls:

  • CE Marking: The mandatory European seal guaranteeing the product meets safety and health standards.
  • UNE-EN 14351-1 Standard: Specifically evaluates window performance against wind, rain, and its insulating capacity.
  • CTE (Technical Building Code): We ensure our installations meet current energy saving and health requirements in Spain.

One of the great advantages of these materials is their low maintenance. To keep them looking like new, you only need:

  • Basic Cleaning: Neutral soap and water for the profiles. Avoid abrasive products.
  • Hardware Greasing: A small amount of lubrication on pivot points once a year (this is very simple using Roto systems).
  • Seal Review: Check that the weatherstripping remains flexible to ensure no air or noise enters.
  • Express Ventilation: Open the windows wide for only 5 to 10 minutes. This is enough to renew the air without cooling the walls.
  • Tilt-and-Turn Systems: Use the top opening for constant and safe aeration.
  • Moisture Prevention: Correct ventilation prevents condensation and mold, maintaining a healthy environment.
