Why insulate with Thermafleece Ultra Wool?

  • Performance - With a Thermal Conductivity of 0.035 W/mK, Thermafleece Original offers better performance than most low density insulation on the market.

  • Cost Effective - Energy savings from using Thermafleece Original mean it can pay for itself in a few years.

  • Long Lasting - Thermafleece Original will last the life of the building and contains a lofting agent to maintain fibre stability and structural integrity throughout.

  • Sustainable - Using Thermafleece Original can reduce carbon emissions by many tonnes over the lifetime of use.  Wool fixes carbon dioxide helping reduce greenhouse gas levels.

  • Safe- Thermafleece Original is safe to handle without the need for personal protective equipment.  It can be recycled or safely disposed of at the end of its life.

Installation and Handling

Thermafleece UltraWool is harmless and can be installed without gloves or protective clothing, although we recommend you wear a dust mask in enclosed spaces such as lofts.

Thermafleece UltraWool can be used in conjunction with a vapour permeable membrane to retain the benefits of water vapour absorption and release.

Protect the insulation from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.

For accurate cutting, tightly compress or clamp the insulation between two pieces of solid 15mm board. Overhang the slab where you want to cut keeping the two board edges aligned.  Cut the edge with a scalloped edged knife and keep the blade firm and square against both board edges throughout.
