These foam door and window seals are designed to provide a snug fit, minimising drafts and improving energy efficiency in your home. Crafted from closed-cell foam, they offer excellent thermal insulation properties while remaining flexible enough to accommodate slight variations in frame size. These seals contribute to a quieter environment by reducing noise transmission through gaps around doors and windows.
Foam seals are particularly effective at sealing smaller cracks and crevices that traditional weather stripping may miss. They're simple to install, requiring no specialist tools or expertise – just peel off the backing and apply directly to the door or window frame. This type of seal offers a cost-effective solution for improving your home’s insulation performance and reducing energy bills.
These foam seals are a versatile addition to any property looking to enhance its comfort and reduce heat loss. They can be used on internal and external doors, as well as windows, and their adaptable nature makes them suitable for various frame materials like uPVC, wood, and aluminium. Remember to measure accurately before purchasing to ensure you select the correct size for your specific requirements.

FAQ
What’s the typical lifespan of foam door & window seals?+
The longevity of these foam seals depends on environmental factors like temperature fluctuations and exposure to sunlight. Generally, they will last between 3-7 years with proper installation and maintenance, but this can vary.
How do I measure my door or window for the correct seal size?+
Measure the width and height of the rebate (the gap between the glass and the frame) accurately. Add at least 10mm to both measurements for a comfortable fit – foam expands slightly when compressed.
Can I install these seals on windows with double or triple glazing?+
Yes, you can! These foam seals are designed to work effectively with all types of glazing, including double and triple-glazed windows. Ensure the seal is applied correctly over the entire rebate gap.
Are these foam seals suitable for external doors?+
Absolutely. Foam seals provide excellent protection against wind and rain when used on external doors. However, consider UV exposure, which can degrade the foam over time; regular checks are recommended.
What tools do I need to install these foam seals?+
You’ll only require a utility knife or scissors for trimming excess foam and possibly a small roller to ensure a tight fit against the frame. No special tools are needed for installation.
Will foam seals damage my paintwork?+
When installed correctly, these foam seals shouldn't cause any damage to your paintwork. However, it’s advisable to test a small area first if you’re concerned about adhesion.
How do I clean foam door & window seals?+
Use a damp cloth and mild detergent to gently wipe the seals. Avoid using harsh chemicals or abrasive cleaners that could damage the foam material.
Are these foam seals resistant to moisture?+
The closed-cell structure of the foam provides inherent resistance to moisture, preventing water absorption and maintaining its effectiveness over time.
Can I cut the foam seal to fit a non-standard rebate size?+
Yes, you can carefully trim excess foam with a utility knife. Ensure you leave enough material to create a secure contact point with both the glass and the frame for optimal sealing.
What is the difference between different foam densities?+
Foam seals come in various densities; higher density foams offer greater compression resistance but might be slightly harder to cut. Lower density foams are easier to manipulate, but may compress more readily over time.
