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.
