Rated 5 out of 5 by Draft exclusion sorted I live in a 1930s house with as much modernisation as a Model T Ford therefore to try and insulate most of the (currently) single glazed windows I used this silicone sealant in an effort to ward off the cold draughts coming though the numerous holes between the frames and openers. Yes it will stop me from opening the windows but for now the benefits outweigh the drawbacks. This product was lovely and thick (high modulus) and smoothed into every location blindingly well. If you need draught exclusion use this stuff. It's newly applied so can't give a long term appraisal of it's mould resistance or adhesion (bathroom application) but for now I'm happy bunny. 17 Nov 2015
Rated 4 out of 5 by Sensible glazing silicone Good consistency and easy to apply, doesn't skin too quickly 12 Nov 2015
Rated 4 out of 5 by good sealant Bit too early to comment on the performance and reliability but applying it was easier enough. Hardly any odour, and dried in the right amount of time, not too quick and not forever. Does what its meant to do. 28 Sep 2015
