About this garage door seals
Stormguard 7m Black Garage Door Brush-Pile Draught Seal
A threshold seal handles the bottom of a garage door, but the cold also comes in around the sides and the head. Those gaps are narrower and more irregular, which is where a brush-pile seal does better than a rubber bulb. The bristles brush against the edge of the door and close the gap without making the door hard to shut.
This Stormguard roll is 7 metres long in black polypropylene, with a pile height of 15mm and a self-adhesive backing. It is designed to seal gaps of 5mm to 15mm around garage doors, and the soft pile means an up-and-over or a sectional door can pass without resistance.
Seven metres is enough for a single garage door frame, along both sides and the top, with a little left over. Clean and dry the frame, fit the strip in a mild spell, and press along its full length. Combine it with a threshold seal on the floor for a complete job.
