This Foam Seal Draught Proofing & Weatherstripping kit offers a targeted solution for sealing gaps around windows and doors, preventing cold air drafts and improving energy efficiency. Constructed from dense polyurethane foam, it's designed to conform tightly to irregular surfaces, creating a robust barrier against the elements. This particular formulation is ideal where flexibility and a high degree of airtightness are crucial, particularly in areas with fluctuating temperatures.
The foam’s closed-cell structure minimizes air permeability, effectively stopping draughts and reducing heat loss. It's suitable for use on wood, metal, and plastic frames – simply cut to size using a utility knife or scissors. This kit provides a cost-effective way to enhance your home’s insulation and comfort levels without the need for extensive renovation work.
While offering excellent performance against drafts, it's important to note that this foam sealant is best suited for sealing gaps up to 20mm wide. For larger openings, consider combining this product with other draught proofing measures. Ensure surfaces are clean and dry before applying for optimal adhesion and longevity.

FAQ
What tools do I need to use this foam seal?+
You’ll primarily need a utility knife or scissors for cutting the foam to size. A tape measure is essential for accurate measuring, and a soft mallet can help ensure tight fitting if needed. Gloves are recommended for handling the foam.
How do I prepare the surface before applying the foam?+
The surface must be clean, dry, and free from loose paint or debris. A light sanding can improve adhesion, but it’s not strictly necessary. Remove any existing draught proofing materials first for best results.
Can this foam seal be painted over?+
Yes, the foam sealant is paintable once fully cured (approximately 24-72 hours). Use a primer designed for polyurethane foams to ensure optimal adhesion and longevity of the paint finish. Avoid using solvent-based paints directly on the foam.
Is this foam seal suitable for exterior use?+
While it can be used externally, we recommend protecting the foam with a weatherproof sealant or coating to prolong its life and prevent degradation from UV exposure and moisture. Regular inspection is advised.
How does this Foam Seal compare to other types of draught proofing?+
Unlike felt or brush strips, this polyurethane foam offers superior airtightness due to its closed-cell structure. It’s more resilient and less prone to compression over time, providing a longer-lasting solution for draughtproofing.
What is the typical lifespan of this Foam Seal?+
With proper installation and maintenance, this foam seal can last 5-10 years or longer, depending on environmental conditions. Regular inspection and reapplication may be needed if exposed to harsh weather.
Can I cut and shape the foam to fit complex gaps?+
Absolutely! The foam is designed to be easily cut and shaped using a utility knife or scissors. Take your time and make clean cuts for optimal sealing performance. It’s best to cut slightly larger than needed and trim afterwards.
How does this Foam Seal affect the paint on my doors/windows?+
When painted correctly with a suitable primer, the foam sealant should not negatively impact existing paint finishes. However, always test a small, inconspicuous area first to ensure compatibility and adhesion.
What is the density of this foam seal?+
The foam has a high density which contributes to its effectiveness in blocking drafts. This density also allows it to maintain its shape and provide a tight fit even under pressure.
Does this Foam Seal require any specific adhesives?+
No, the foam sealant is designed to create a strong bond directly with surfaces through surface tension. However, for added security in high-traffic areas or exposed conditions, you could consider using a flexible sealant along the edges.
