I received samples of the 25mm and 50mm brush seal and I think the 50mm will be the best option to suit the installation.
Overall, I’m very satisfied with the kit. The installation process was straightforward, and once installed it covered about 95% of the gaps around my garage door, which made a noticeable difference.
One small suggestion: it would be even better if the kit included a bit more Liquid Nails. Also, if the brush were about 1.5 cm longer, it could provide better coverage.
No way one lot of glue is enough, you need 2 . The glue doesn't stick to the metal kit you need to apply it to the wall. Add to the fact the the metal backing closed the gap to the door so much it would not slide and close correctly. Left me with a whole bunch of work to do and a garage that would not close.
Honestly for the price I paid I'm disappointed. It would be tough to recommend this
Liam and Ben did a great job, from answering questions on the installation to the actual install itself (which took under an hour). Makes sense huge difference to the garage - noise, heat, and dust are all much lower. Recommended.
