This high-density felt draught proofing and weatherstripping offers a robust solution for sealing gaps in windows and doors, helping to maintain comfortable temperatures within your home. Constructed from densely packed felt fibres, it’s exceptionally effective at blocking cold air drafts and reducing heat loss during the winter months. The material's inherent resilience and flexibility ensure a secure fit, conforming to irregular edges for optimal performance.
The dense nature of the felt provides superior insulation compared to less robust materials, contributing to significant energy savings. It’s ideal for use in garages, sheds, or any area where draughts are a concern. The weatherstripping can be easily cut and trimmed to fit various sizes and shapes, providing a flexible and adaptable sealing solution.
This product is suitable for both internal and external applications. While durable, remember that felt is susceptible to damage from sharp objects – handle with care during installation. Ensure the surface you’re applying it to is clean and dry for optimal adhesion and longevity, maximizing its effectiveness against drafts and weather.

FAQ
What sizes are available?+
The high-density felt draught proofing comes in a variety of lengths, typically ranging from 1 metre to 5 metres. Widths vary between 75mm and 150mm, allowing for adaptable sealing across different gap sizes.
How do I install it?+
Simply measure the gaps you need to seal and cut the felt to size using a sharp utility knife. Apply firmly to the frame, ensuring it conforms tightly to the edges. For better adhesion, a light application of silicone sealant can be used.
Is this suitable for exterior use?+
Yes, this high-density felt weatherstripping is designed for both interior and exterior applications. However, regular inspection is recommended to ensure it remains unaffected by prolonged exposure to the elements – consider applying a protective sealant for enhanced durability.
Can I cut this to fit oddly shaped gaps?+
Absolutely! The flexibility of the high-density felt allows you to easily cut and shape it to accommodate irregular gaps in doors and windows. Use a sharp blade and take your time to achieve a precise fit.
What tools do I need?+
You’ll primarily need a utility knife or scissors for cutting the felt to size, as well as a measuring tape and possibly a small roller for applying pressure against the frame.
How durable is this material?+
The high-density felt offers good durability but is susceptible to damage from sharp objects. Handle with care during installation and consider protecting it from abrasion if necessary.
Will this affect paintwork?+
While generally low in VOCs, prolonged contact could potentially stain painted surfaces. It's advisable to test a small area first or use a protective sealant between the felt and the paint.
Does this provide complete airtightness?+
The high-density felt effectively blocks drafts but doesn’t guarantee a completely airtight seal. For truly airtight sealing, consider combining it with other weatherproofing materials.
What is the recommended application temperature?+
This draught proofing performs optimally in temperatures between 5°C and 25°C. Extreme cold can reduce its flexibility and effectiveness.
How does this compare to foam weatherstripping?+
High-density felt generally offers a tighter fit than foam, particularly in irregular gaps. It’s also quieter when drafts are blocked and less prone to compression over time.
