Savings and tax deductions


Thermal insulation: more comfort, less waste

Windows and doors are crucial points for a building’s thermal insulation. In older homes in particular, up to 25% of heat loss can be attributed to outdated or non-performing frames.

Through the use of high energy-efficient window frames, Seredil concretely contributes to improving the building’s energy class, reducing consumption, and enhancing indoor comfort.

Our products are designed with:

  • Perfect airtightness and watertightness to eliminate drafts and infiltrations
  • Thermowelded corner joints
  • Double or triple sealing gaskets
  • Multi-chamber technology that improves thermal and acoustic insulation

In addition, large glazed surfaces allow you to increase natural light and make the most of the sun’s passive heat, further contributing to energy savings. All Seredil window frames comply with legal requirements for thermal insulation, both for new constructions and for renovation projects.


No maintenance, only long-lasting durability

Our window frames are designed to withstand weather conditions without alterations over time. Rain, wind, and UV rays do not compromise aesthetics or functionality, thanks to the quality of the materials and the care taken in installation.

Aluminum, in particular, is a material that is:

  • Extremely resistant to weathering
  • Stable over time, even with significant temperature fluctuations
  • Unalterable in color, both in white and colored versions
  • Easy to clean with a simple cloth and neutral detergents

Our frames do not require periodic repainting or extraordinary maintenance: an advantage in terms of time, cost, and sustainability.
