The Brush Seal Draught Proofing & Weatherstripping system offers a robust solution for sealing gaps around windows and doors, preventing cold air drafts and improving energy efficiency. Constructed from durable, high-density foam, this material provides superior cushioning and compression compared to traditional felt or rubber weatherstrip options. Its unique design effectively blocks air movement while maintaining flexibility to accommodate minor building movements.
This Brush Seal profile is particularly well-suited for applications requiring a tight seal against irregular surfaces or where vibration is present. The dense foam conforms precisely to gaps, creating a barrier that minimizes air leakage and reduces noise transmission. Installation is straightforward with readily available tools – simply cut to size and secure using the provided adhesive strips or mechanical fasteners.
Designed for long-term performance, Brush Seal weatherstrip resists degradation from UV exposure, moisture, and temperature fluctuations commonly found in UK homes. This system delivers significant thermal benefits, helping to maintain a comfortable indoor environment and reducing your heating costs. It’s an ideal choice for upgrading older windows and doors or creating airtight seals during new construction projects.

Is Brush Seal weatherstripping suitable for exterior use?+

Can I paint Brush Seal weatherstripping?+
While Brush Seal can be painted with most standard acrylic paints, we advise testing the paint on a small, inconspicuous area first to ensure compatibility and avoid affecting the adhesive properties.
What tools do I need to install Brush Seal?+
