Polyurethane (PU) foam Upvc/Aluminum window weatherseal strips
Polyurethane foam weather seals are high-performance window and door seals designed to provide improved thermal and acoustic insulation. These seals are typically made of polyurethane (PU) foam as the core and coated with a layer of vinyl or polyethylene film(PE) to provide both softness and durability. They are commonly used for kerf installation and can be easily inserted into prefabricated notches in door and window frames.
Main features of Q Lon foam weather seals
1) Excellent thermal and acoustic insulation
The porous foam structure effectively blocks air flow and noise, helping to maintain a stable indoor temperature and reduce noise disturbance.
2) Strong durability
It is resistant to high temperatures, moisture and UV rays, not prone to aging or deformation, and can maintain performance for a long time even in harsh environments.
3) Easy to install
The kerf design does not require additional glue and can be firmly inserted into door and window frames, making installation quick and easy.
4) Energy saving and environmental protection
By reducing air leakage through the gaps between doors and windows, energy consumption is reduced, helping users save on heating and cooling costs.
Difference between Q foam weather seal and ordinary EPDM sealing strip
Material: PE coated weather seal uses PU foam material and PE film coated, while EPDM sealing strip uses EPDM, which has excellent elasticity but is prone to permanent deformation after long-term use.
Compression deformation: The foam structure of the coated sealing strip can quickly return to its original shape after multiple compressions, and is more suitable for dynamic sealing (such as sliding doors and windows).
Weather resistance: Although EPDM materials also have excellent aging resistance, the coating layer of the coated sealing strip makes it more stable in long-term outdoor use.
Poly foam weather seals applications:
Sliding doors and windows: prevent air and water leakage through gaps.
Broken bridge aluminum doors and windows: improve air tightness and thermal insulation.
Residential and commercial buildings: improve living comfort and energy saving.
Coated sealing strips are suitable for users who pursue high-performance sealing effects, especially in scenarios that require long-term durability and dynamic sealing.
