This is a gorgeous install of our 100% pure SheepWool Optimal insulation in a floor application. You can see how easy it is to lay these rolls between the joists, and the Optimal – being medium density – is really easy to cut to fit, no matter what the joist width. The customer here also used our ‘SilentJoist’ again, 100% pure wool and this is really the natural and effective way to reduce structureborne sound transmission caused by contact between joists and floor / subfloors and is suitable for use with underfloor heating (as is the insulation also). Silentjoist is ideal for use, when you are then laying timber flooring directly on top of the joists. This beautiful job was done by https://the-sandman.co.uk/
