FAQ
What tools do I need to install these seals?+
You'll primarily need a utility knife or scissors for cutting the rubber seal to size, as well as a small roller or smoothing tool to ensure it conforms tightly against the surface. A tape measure is also helpful for accurate measurement.
How much sealant do I typically need for a standard door?+
For a standard single-door installation, you’ll likely require approximately 1.5 – 2 metres of the D-Shape Rubber Seal. This will allow sufficient length to cut and fit around the entire perimeter of the door frame.
Can I use these seals on windows with painted frames?+
Yes, you can. However, it’s advisable to clean the window frame thoroughly before applying the seal to ensure good adhesion. Applying a small amount of silicone lubricant might also help with installation and prevent tearing of the rubber.
Are these seals suitable for external use?+
While they offer weather protection, prolonged exposure to direct sunlight or extreme temperatures can degrade the rubber over time. For optimal performance on exterior applications, consider applying a silicone-based lubricant periodically.
How do I measure the gap I need to seal?+
Use a flexible measuring tape to accurately determine the width of the gap around your door or window frame. Ensure you account for any irregularities in the surface to achieve a snug and effective fit with the D-Shape Rubber Seal.
What if the sealant doesn't stick properly?+
Ensure the surface is clean, dry, and free from grease or dust before applying. Applying firm pressure whilst installing and using a suitable adhesive (such as silicone) can also improve adhesion.
Are these seals compatible with different door materials?+
The D-Shape Rubber Seal generally works well on wood, metal, and PVC doors and frames. However, if you're working with particularly soft or brittle materials, test a small area first to ensure compatibility.
Do I need to apply any adhesive?+
While the rubber seal has inherent adhesion, applying a thin bead of silicone sealant along the gap before pressing the seal into place will significantly improve its grip and long-term performance. This is particularly recommended for larger gaps or uneven surfaces.
What’s the typical lifespan of these seals?+
With proper installation and maintenance (periodic cleaning and lubrication), these D-Shape Rubber Seals can typically last 5-10 years, providing ongoing draught protection and energy savings. Regular inspection will help identify any signs of wear or damage.
What is the rubber compound made from?+
The seals are constructed from a closed-cell synthetic rubber designed for durability and resistance to weathering. This material offers excellent elasticity and maintains its sealing properties over time, providing a reliable solution against drafts.
