Blanket Wool Insulation

Insulation material for walls and ceilings is available in wool blanket form.

It is available for installation into the walls and ceilings of buildings.

Due to varying dimensions in stud and joist sizes, particularly in older homes, material is manufactured in blanket form.

For Walls, the product can very easily be torn by hand in a horizontal direction, thereby enabling exact fits in situations where the installer is faced with non standard dimensions.

For Ceilings, the material is rolled out between the joists.

Material is safe and healthy and requires no protective clothing for handling or installing.

This product takes advantage of the unique features of natural wool fibre such as strength, durability, bulk and resilience. These features ensure that material maintains its loft and shape especially after packaging and installation compression. This means that the thermal rating of the insulation is consistant with its tested rating.
