This product is the ideal solution for replacing an existing seal or for initial installation in compatible aluminum window systems.
Why choose our S331 profile seal?
We produce our S331 profile seal from high-quality materials (often EPDM – ethylene propylene diene rubber), which guarantees exceptional resistance to weather, UV radiation, and aging. This material maintains its flexibility and sealing properties even in extreme temperatures, whether in freezing winter months or during hot summer days. Thanks to the precise S331 profile (with groove dimensions of 3.0 mm, a total width of 7.3 mm, and a height of 10.0 mm), the seal fits perfectly into the frame of your aluminum windows. This eliminates leaks and ensures optimal thermal and sound insulation. Forget about uncomfortable drafts and reduce your heating and air conditioning costs.
Advantages of the S331 profile seal for aluminum windows
Replacing an old seal with a new seal for aluminum windows brings many benefits. In addition to the energy savings and increased comfort already mentioned, this seal effectively protects the interior from dust, pollen, and moisture. It improves the overall functionality of the window and extends its lifespan by protecting the hardware from dirt and moisture. Installing our S331 profile seal is simple and can be done yourself. Just remove the old seal, clean the groove in the frame, and then press the new seal into place around the entire perimeter. Thanks to its flexibility, it easily adapts to the corners of the window frame. This window seal is the key to a quieter and more energy-efficient home.
