Optimal thermal protection and fashion implement the highest requirements.

One of the most important issue in design the passive houses is aim to obtain maximal as is possible insulation of a building and elimination generation of a thermal bridges. The key meaning is to receive as low as is possible a request on energy and maximally bound energy lost. For this reason very important in passive houses are the windows, they are one of the most important elements in construction of a hermetic building, at the same time as the barriers they are the worst thermal isulation factors. Their major role manifested in that, they limit the thermal energy loses and passive use solar energy from the sun, to heating the building inside and shined the room. In respond on the more rigorous norms,producers of the window systems, work out on a windows series for the low energy using and possive houses.
The base of the Aluplast systems solutions Passiv-Hous series can be profile by IDEAL 5000 - five chambers or IDEAL 6000 - six chambers, width sizes 70 mm or 80 mm.In the profiles are usage special reinforcements with higher thermal isulation with the separator material, additionally the reinforcement chambers are filled by special formed polyurethane foam. The profiles are middle sealed, where is used third seal and diffuse third dry chamber where work the ferrule. In Technical Windows Institute in Roseheim was tested window made in Ideal 5000 Passiv-Haus system, the window had the thermal isulation factor equal 0,84 W/m²K, in this case used glass packet with penetrate factor U= 0,7 W/m²K. Furthermore the systems implement the most rigorous thermal protection norms, in opposite to many other solutions using varied types of covers, the systems have modern designs and compact construction agreed with new trends on the windows market. Mild curves line give windows modern and harmonic design.
