Rich in British sheep’s wool - designed to give extra thermal performance where depth is limited and our highest level of acoustic performance
Thermafleece UltraWool is a high density, highly efficient insulation made from 75% British sheep’s wool and 25% recycled polyester. UltraWool is the ideal choice if you are looking for maximum thermal performance when space is at a premium. What’s more, with a density of 31 kg/m3 Thermafleece UltraWool helps provide exceptional acoustic insulation performance in wall, floor and roof systems.
Research shows that using 75% wool in combination with recycled fibres outperforms alternative products with a higher percentage of wool. Our wool rich blend ensures you get the full benefit of sheep’s wool with enhanced performance, breathability, durability and sustainability.
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 is not irritating to the skin, eyes or respiratory tract.
To retain the benefits of water vapour, absorption and release, Thermafleece UltraWool may be used in conjunction with a vapour permeable underlay. Protect the insulation from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.
Thermafleece UltraWool 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.
The Alliance for Sustainable Building Products (ASBP), in collaboration with the ASBP Plastics in Construction Group, has launched an exciting new innovation pitch series. Aimed at innovators, start-ups and manufacturers launching new product ranges, the purpose of the ‘Dragons’ Den’ style event programme is to identify innovative alternatives to conventional plastic building materials and packaging. The products can be at any stage of the innovation cycle from early development to market ready.... read more
