FAQ
What materials are these mid-range seals typically made from?+
You’ll find options utilising neoprene, silicone, and foam. Neoprene offers excellent durability and thermal insulation, while silicone provides superior weather resistance and is often used for external applications. Foam seals are generally the most cost-effective solution for draught reduction.
How do I measure my window or door for a seal?+
Measure the width and height of the rebate (the groove where the glass sits) carefully using a tape measure. Add approximately 10mm to each measurement for overlap, ensuring you have enough material to secure the seal properly against the frame.
Are these seals suitable for replacing existing window draught excluders?+
Yes, many of these mid-range seals are designed as direct replacements for standard draught excluders. However, always measure your existing seal’s dimensions before purchasing a replacement to ensure compatibility and an accurate fit.
Do I need different seals for internal and external doors/windows?+
Generally, yes. External seals require materials with superior weather resistance – silicone or neoprene are preferable – while internal seals can often utilise foam for cost-effectiveness and good thermal performance. Always check the product specifications.
How do I install a window seal?+
Clean the rebate thoroughly before applying the seal, ensuring it’s free from dirt and debris. Use a rubber mallet to gently tap the seal into place, working your way around the entire rebate for a snug fit – avoid using excessive force.
What is the typical lifespan of a neoprene door seal?+
Neoprene seals typically last between 5-10 years with proper maintenance. Regular cleaning and occasional inspection can help extend their lifespan, ensuring continued thermal performance.
Can I use these seals on UPVC windows and doors?+
Yes, many of the silicone and neoprene options are suitable for UPVC frames. However, ensure the seal is compatible with the frame material to avoid potential damage or adhesion issues – consult product descriptions carefully.
Are there any specific tools I need for installation?+
You’ll primarily need a measuring tape, a rubber mallet, and possibly a utility knife for trimming excess sealant. Gloves are recommended to protect your hands during the installation process.
What is the benefit of using a foam seal compared to silicone or neoprene?+
Foam seals are generally more affordable than silicone or neoprene and provide excellent thermal insulation. While less durable, they're suitable for areas where high weather resistance isn’t essential and offer a significant draught reduction at a lower cost.
What does ‘thermal conductivity’ mean in relation to these seals?+
Thermal conductivity measures how easily heat flows through the material. A lower value indicates better thermal insulation, meaning the seal will be more effective at preventing heat loss or gain – look for seals with a low thermal conductivity rating for optimal energy efficiency.
