- • Sealing Performance: Blocks draughts and water for gaps between 3–5mm, reducing heat loss
- • Best for: Homeowners with UPVC frames seeking straightforward draught-proofing
- • Not ideal for: Frames with groove widths outside 3.2–4mm or non-UPVC profiles
Push-in rubber gasket is designed for standard UPVC frame grooves and seals 3–5mm gaps to limit wind and rain ingress. Simple replacement requires removing the old seal, cleaning the groove, then pressing the new strip into place.
Reduce Heat Loss - with a rubber gasket that seals 3–5mm gaps
Compressible rubber fills the space between frame and sash to form a continuous barrier, closing common leak paths. The profile is sized to sit in standard grooves so the seal compresses to match the gap.
Lower heat loss across window and door joints, helping maintain a steadier room temperature and reducing cold spots.
Quick DIY Replacement - thanks to push-in fitting without tools
Strip is designed to slot into existing frame grooves after the old gasket is removed and the groove cleaned. No specialist tools are required, only manual pressure to seat the profile.
Fast swap for worn seals that makes draught-proofing accessible to most homeowners and saves the time and hassle of hiring a tradesperson.
Better Weather Protection and Quieter Rooms - with a water-resistant rubber profile
The rubber compound repels water and closes gaps that allow driving rain and wind through. Continuous contact along the groove also interrupts paths for airborne noise.
Improved resistance to rain ingress and a noticeable reduction in outside noise at each sealed joint, creating a drier, calmer indoor environment.
