Questions & Answers FAQ
By aligning the PA66 GF25 polyamide barrier strips, central pressure-equalized gaskets, and insulated glass spacers along the exact same vertical plane, the system creates an unbroken thermal barrier. This prevents cold and heat bridging, significantly cutting HVAC heating and cooling loss throughout the year.
The Wehag base-free handle removes the cumbersome traditional escutcheon plate for an ultra-clean, minimalist flush look. Internally, precision German engineering ensures smooth gear engagement, rattle-free multi-point locking, and robust long-term durability.
The window utilizes three perimeter layers of high-elasticity automotive EPDM gaskets to form separate pressure chambers, while factory pin-injection sealant reinforces every profile corner. This dual protection eliminates joint gaps, stops wind drafts, and guarantees superior watertightness under heavy storm conditions.
The system balances atmospheric pressure between internal and external chambers, allowing storm runoff to drain away quickly via gravity while actively preventing external wind gusts from forcing water backward through the sill and into interior walls.
The extra-wide 25mm air cavity between the dual 5mm tempered glass panes substantially slows the transmission of low- and high-frequency sound waves. Supported by tight triple-gasket compression, it dampens outdoor environmental disturbances to achieve an acoustic isolation rating of up to 38dB.
