Features:
Joist is a roll of 3.5mm thick Sheep Wool Insulation, which is designed as a premium joist underlay. Joist is suitable for use under new or existing floors in refurbishment projects or new builds. Joist is especially popular in older houses where there may be existing gaps in the floorboards, allowing underfloor drafts to make a room feel cold. The thick layer of SilentWool: joist under joists will also act as a long-lasting underlay, protecting the joists from premature wear and tear.
