About this draught excluder tape & foam strips
Stormguard 10m White EPDM P-Profile Draught Seal
Stormguard is a name that is well known to anyone who has draught-proofed a British home, and its self-adhesive EPDM rubber is a staple of that work. The P-profile shape has a flat tail that sticks to the frame and a hollow bulb that squeezes against the closing door or window.
This roll is 10 metres in white and about 4mm thick, designed to seal gaps of 3mm to 5mm. EPDM is a synthetic rubber that resists weather and keeps its flexibility for years, so it is a sensible choice for a front door frame or a window that gets a lot of sun.
Before you buy, measure the gap with a card or feeler gauge. If the gap is within 3 to 5mm, the strip should compress gently and close the door without strain. If you need to go thicker or thinner, a different profile will suit better. Stick it on a clean, dry frame and press it firmly into place.
