The current trend in architecture is to achieve more sustainable and energy-efficient buildings. The aim is to reduce the emission of polluting gases into the atmosphere, while also increasing the economic viability of homes.
For this reason, any energy modification in a house means to optimize its isolation. The improvement of the thermal insulation of the building can suppose energy savings and a reduction of CO2 emissions of a 30% in the consumption of heating and air conditioning.
In addition to the thermal insulation itself, other elements such as gaps, orientation and finishes have an impact on the energy efficiency of a building. For example, it should be noted that only the installation of high energy efficiency windows with polyurethane profiles that prevent heat from escaping can considerably reduce leaks and currents caused by windows and glass (estimated at 40 % of the total energy losses of a dwelling).
Advantages of the use of polyurethane systems in the profile
Traditionally, we use metallic, PVC or wood profiles for windows and other hollows in the facades. In this range of materials, the polyurethane also provides a solution for window profiles.
One of the biggest enemies in the thermal insulation of a house are thermal bridges. In order to prevent them, polyurethane can provide its excellent thermal properties to the carpentry of the envelope, thanks to the possibility of molding window profiles with polyurethane systems.
Polyurethane systems for the manufacture of windows have a double function. On the one hand, they act as thermal insulation in a conflicting area such as the gaps in the façade. And on the other hand, they have a sealing effect, allowing the windows made of polyurethane to provide watertightness in the building, to reduce the demand for air conditioning and to maintain the comfort in the interior.
It is estimated that the use of polyurethane systems in the manufacture of window profiles, along with other thermal insulation measures, can contribute to saving the equivalent of the annual energy needed to manufacture up to 135 million vehicles.
Contribution to the reduction of energetic losses in the envelope holes
The European regulations require more and more demanding levels in terms of energy demand. One of the measures that can contribute to the reduction of energetic losses of the envelope is the improvement of the profile by the incorporation of polyurethane systems in its manufacture.
Synthemad 9669-X-85 polyurethane system for the manufacture of window profiles
Synthesia International manufactures a polyurethane system that offers a solution to improve the energy efficiency of windows. This is the Synthemad 9669-X-85 system.
The system is designed for the manufacture of molded parts, of high technical value in a wide range of density, especially indicated in the sector of the profiles of windows and doors.
Components of Synthemad 9669-X-85
This polyurethane system consists of two components:
Component A: Polyol 9669-X-85. Mixture of polyols containing catalysts, surfactant additives and foaming agents
Component B: Isocyanate NH 10. MDI (Diphenylmethane diisocyanate)
