FAQ
What size aluminium door and window seals do I need?+
Measure the gap between your door or window frame and the glazing unit carefully. Allow approximately 5-10mm of overlap – this is crucial for creating a proper seal when compressed. Don’t just measure the glazing; account for the entire perimeter where the seal will sit.
Are these seals suitable for external doors?+
Yes, these aluminium door and window seals are designed to withstand outdoor conditions. However, ensure they are protected from direct sunlight and prolonged exposure to harsh chemicals or cleaning products to maximise their lifespan.
How do I install the aluminium seals?+
Typically, you'll need a utility knife to trim the seal to size. Follow the manufacturer’s instructions for applying the seal – often this involves peeling off a backing and pressing it firmly into place against the frame. A small roller can help ensure good adhesion.
What is the aluminium used in these seals made of?+
These seals utilize high-grade, marine-grade aluminium which provides exceptional resistance to corrosion, ensuring they perform reliably even in damp or coastal environments. The specific alloy composition will vary depending on the manufacturer's specifications.
Can I cut these aluminium seals to a custom size?+
Yes, you can usually cut these seals with a utility knife. However, be careful not to damage the sealing surface. It’s recommended to use a straight edge for accurate cuts and allow for slight overlap when installing.
Will aluminium door seals expand or contract with temperature changes?+
Aluminium is relatively stable in temperature but can still expand slightly. The design incorporates this by allowing for some movement while maintaining a tight seal. Ensure the seal is correctly installed to allow for natural expansion/contraction.
How do I clean aluminium door and window seals?+
Use a damp cloth with mild soapy water to gently clean the seals. Avoid using abrasive cleaners or solvents, as these can damage the aluminium surface and compromise the seal’s effectiveness.
Do these seals require any adhesive?+
No, most aluminium door and window seals rely on friction and pressure for adhesion. However, some manufacturers may offer adhesive strips for enhanced stability; check the specific product details.
What is the typical lifespan of an aluminium seal?+
With proper installation and maintenance, these seals can last for 10-20 years or more. Regular cleaning and protection from extreme weather conditions will prolong their service life significantly.
Are these seals compatible with all window frame materials?+
These aluminium seals are generally suitable for use with uPVC, timber, and composite windows. However, ensure the sealing surface is clean and free of debris before installation for optimal performance.
