    To retain the benefits of water vapour, absorption and release, Thermafleece CosyWool  roll may be used in conjunction with a vapour permeable underlay.

    Cutting Tips

    75mm Thermafleece CosyWool Sheep wool roll (8.5mx570mm pack of 2) can be cut using a straight edge and a Stanley knife, or simply torn apart.

    For more accurate cutting, tightly compress or clamp the insulation between two pieces of solid 15mm board. Overhang the fleece where you want to cut keeping the two board edges aligned. Saw cut the edge using a sharp, scalloped edged knife and keep the blade firm and square against both board edges throughout. Trim any fine remaining fibres with large scissors or shears.

    Acoustic Partition Walls…

    This application note gives examples of timber frame internal wall constructions which, when built correctly, will meet or exceed the performance standards set out in Approved Document E, ‘Resistance to the passage of sound’.
