What are window and door gaskets?
Gaskets are mechanical seals which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. A gasket seals the sash to the frame so as to prevent anything from entering the window or door. Things like dust, debris, air, water, etc can accumulate in the window frames due to inefficient sealing of the windows.
The number of gaskets within the window system can have a great effect on the durability of the hardware, as well as the window's overall energy efficiency.

How do gaskets contribute to the weatherproofing of your home?
Weather Protection
Gasket #1 - The first gasket seals and protects the sash from the elements. High-performance, especially passive house windows, improve a home’s air quality due to their superior airtight structure. This airtight property of Internorm windows prevent dust, allergens, and air from permeating through the gasket, therefore eliminating the presence of condensation and mould. Lastly, the chamber between gasket #1 and gasket #2 drains water through weep holes to keep your home dry and healthy.

Durability
Gasket #2 - Most manufacturers offer only 2 gaskets, which has downsides. It causes difficulties while operating the window over a course of time. Water might continuously fall and corrode the hardware. Internorm goes above the industry norm to provide maximum durability with 3 continuous gaskets. Gasket #2 protects the hardware from moisture and hence, avoiding rust and other functional issues resulting from long-term exposure to water or humidity. Proper sealing makes for easy window cleaning and very little maintenance.

Maximum Comfort
Gasket #3 - The final seal ensures a calm and comfortable interior with improved sound reduction values and stable temperatures. Enjoy peace and quiet with sound reduction up 47 dB! The chamber construction along with the triple glazing and gasket system optimize thermal transmission with consistent temperatures throughout your home all year round.
Sit comfortably next to your windows without drafts.
