The EarthWool® External Wall Batt range is a new
generation of softer, safer and more environmentally friendly glasswool
Advanced compression packaging reduces handling time and the risk of
damage in transit and on-site.
Although the product is primarily designed for use in external walls it
can also be used for internal walls to reduce sound transmission from
room to room. It is thermally efficient and cost effective in saving
energy and providing increased comfort in buildings.
Batts are the traditional insulation product for insulating external
walls and are available in thicknesses to suit 75mm, 90mm and 140mm
timber and metal frames. Unlike reflective foil, EarthWool External Wall
Batts prevent heat gain in summer and heat loss in winter by countering
convection, conduction and radiation.
Knauf Insulation also offers High Density (HD) and Super High Density
(SHD) External Wall Batts with increased density and lower thermal
conductivity to maximise energy savings. A silicon impregnated product is
also available for full brick walls.
