Keys to choosing your windows

Choosing new windows is an important decision that affects home comfort and energy efficiency. To ensure a good purchase, Kömmerling recommends:

  • Analyze needs (insulation, orientation, available space) before buying.
  • Research materials and features thoroughly. PVC is known for its insulation and durability.
  • Choose reliable establishments that offer guarantees and good installation. Review the budget carefully, demanding that it detail models, materials, and accessories.
  • Review the budget carefully, demanding that it detail models, materials, and accessories.
  • Check the installed product and request the official documentation (such as the CE marking).
  • Request an invoice and written warrantywhich are necessary in case of any future problems.
  • Perform proper maintenance, which is easy on Kömmerling windows.

 

These steps ensure a safe, efficient, and long-lasting purchase.

Solutions for efficient and passive construction

The fight against climate change and new energy efficiency regulations have driven changes in construction, favoring sustainable projects such as Passivhaus and NZEB (Nearly Zero Energy Buildings). KÖMMERLING anticipates these demands with systems that exceed current standards in insulation and airtightness.

The KÖMMERLING76 system stands out, improving energy efficiency and reducing energy losses by up to 70%. It includes variants such as the 76MD Zero and AluClip Zero, which adapt to different styles without compromising performance.

In addition, two KÖMMERLING models are certified by the Passivhaus Institute, one for warm-temperate climates and another for cold climates, although most of their systems meet the required values ​​without the need for certification.

They have also developed solutions such as the RolaPlus roller shutter box, designed to prevent air infiltration, and the PremiPlan Plus threshold, which improves accessibility without compromising efficiency.

Sound insulation

Poor sound insulation at home can seriously affect sleep and cause stress. Windows are the main entry point for outside noise, so choosing the right ones is key to improving comfort. Casement windows (tilt-and-turn or hinged) offer a better seal than sliding windows, helping to block out sound. 

The type of glass directly influences insulation: a thickness of at least 6mm is recommended, or laminated glass for situations with high noise levels. Argon-filled cavities and the use of materials like PVC, which acts as a natural sound dampener, further enhance acoustic efficiency. Another key element is the roller shutter box, which must be of high quality and properly installed, as poor workmanship can negate the benefits of the rest of the system.

Kömmerling windows are known for their excellent insulation, achieving noise reductions of up to 48dB, thanks to their low air permeability, the use of PVC, and solutions like the RolaPlus roller shutter box. To confirm the level of insulation, the difference in decibels between the exterior and interior (R-value) is measured. Although there are apps for this, the real difference is noticeable when replacing old windows with high-performance ones.

Windows with Kömmerling profiles, equipped with suitable insulating glazing, can reduce energy loss by up to 75%, saving on heating costs. Similarly, equivalent energy savings are achieved in cooling systems during warmer periods.

Maintaining windows with Kömmerling profiles is really easy. The satin matte surface is less susceptible to dry, wet, or stubborn dirt than a cracked finish. Normally, a mild detergent is sufficient for regular cleaning. Kömmerling window manufacturers recommend "Köraclean."

Because comfort, energy savings, and even the health and well-being of our family can depend on the type of windows in our home. Quality windows, such as PVC windows, reduce outside noise, improve our heating system, make the house more secure, and increase its value. All these aspects make a good window a fundamental element of any building.

A lot. Installing windows made with Kömmerling systems increases the quality and therefore the value of the house. A well-executed renovation increases the property's value, improves its appearance, and allows for better use of space.

  • PVC andthe woodThese materials are good for thermally insulating a room because they have extremely low thermal conductivity. In contrast, the thermal conductivity of aluminum is 1000 times higher. Typically, manufacturers of aluminum profiles break the thermal bridge between the interior and exterior of the room using plastic components. This isn't necessary with PVC, as it's a natural insulator. Besides the profile construction, the type of glass installed in the window is also very important. He PVCIt is one of the most efficient materials for thermal insulation in window systems, as it has very low thermal conductivity and a multi-chamber structure that significantly reduces temperature transfer between the inside and outside.

In the case of aluminum, its thermal conductivity is considerably higher, so manufacturers must incorporate systems ofthermal breakusing plastic parts to improve its insulating performance.

In PVC windows, this additional treatment is not necessary, as the material itself acts asnatural insulator, guaranteeing a high level of energy efficiency.

In addition to the profiles, the type of glass installed in the window (double or triple glazing) plays a fundamental role in the final thermal performance of the system.

The EU sets industry standards to measure the requirements that profiles, complete windows, and professional installation must meet. Windows manufactured with Kömmerling Systems not only meet but exceed many of the technical requirements outlined in European standards.

In winter, windows with single glazing and aluminum frames often develop condensation and frost when the glass is too cold, as the humidity in the room condenses. Thanks to the high thermal insulation properties of Kömerling PVC frames, combined with standard insulating glass, condensation is virtually prevented.

Yes, with the Kömmerling renovation system, it's not necessary to remove the existing wooden frame. Instead, we clad it both inside and out. Once clad, the frame can accommodate a wide variety of sash and post profiles from the Kömmerling range.
