This D-Shape Rubber Seal offers robust draught proofing and weatherstripping solutions for a variety of applications. Crafted from high-density, closed-cell rubber, it provides exceptional resistance to water ingress, dust, and extreme temperatures – ideal for protecting doors, windows, pipes, and other vulnerable areas. The distinctive D-shape allows for a tight seal when compressed, effectively blocking drafts and maintaining internal climates.
The durable rubber compound is designed to withstand the rigours of outdoor use, resisting cracking, weathering, and UV degradation. This makes it suitable for both interior and exterior applications, ensuring long-lasting performance. Its flexible nature also allows for easy installation around irregular shapes and joints, providing a secure and effective barrier against the elements.
This particular seal is designed to be installed in conjunction with traditional draught proofing methods – such as brush strips or foam seals – where a robust rubber element is required. The D-shape offers superior sealing performance compared to simpler profiles, particularly in areas subject to significant air pressure differentials. It's a reliable choice for maintaining energy efficiency and protecting your property from the elements.

FAQ
What are the typical applications for this D-Shape Rubber Seal?+
This seal is commonly used around door frames, window sills, pipe flanges, utility inlets, and any other area where you need a tight, weatherproof barrier. It’s particularly effective in areas exposed to high winds or rain.
How does the rubber compound perform in extreme temperatures?+
The closed-cell rubber is formulated to maintain its flexibility and sealing properties across a wide temperature range, typically from -40°C to +80°C. However, prolonged exposure to extremely high temperatures should be avoided.
What tools are needed for installation?+
You’ll need a utility knife or scissors to cut the seal to length and a suitable adhesive or sealant compatible with rubber for securing it in place. A roller can also aid in ensuring a complete bond.
Can this D-Shape Rubber Seal be painted?+
While possible, we recommend using a specialist rubber paint designed for exterior applications to avoid damaging the seal's properties. Ensure the paint is fully cured before exposing the seal to weather.
What is the typical lifespan of this type of rubber seal?+
With proper installation and maintenance, this D-Shape Rubber Seal can last up to 10-20 years, depending on environmental exposure and usage. Regular inspection for damage is advised.
Is this seal suitable for use with timber frames?+
Yes, the flexible nature of the rubber allows it to conform to the shape of most timber frames providing a good seal. However, pre-treating the wood with a sealant might improve longevity.
How does the D-shape design contribute to its effectiveness?+
The D-shape creates a more comprehensive seal than a simple rectangular profile by conforming tightly to irregular surfaces and maximising contact area when compressed. This reduces air leakage significantly.
What size variations are available for this product?+
This seal is typically sold in continuous lengths, allowing you to cut it to the exact required size based on your project needs. Common widths range from 50mm to 100mm, and thicknesses from 3mm to 10mm.
Is this rubber seal resistant to chemicals?+
The rubber compound is generally resistant to common household cleaning products and solvents but prolonged exposure to strong acids or alkalis should be avoided. Check the manufacturer's datasheet for specific chemical resistance details.
How does the installation process differ from using foam weatherstripping?+
Unlike foam, the rubber seal requires compression to achieve a tight seal. You’ll need to firmly press it against the surface before securing it with adhesive or sealant to ensure optimal performance and longevity.
