BUILT/ builders merchants are open 7 days a week for the local tradesperson, so you can get insulation online or direct from our one of our branches. Our warehouse stocks insulation for lofts, walls, cavity walls and roofs, made from several highly effective materials including:
PIR (polyisocyanurate) is the high-quality material found in Celotex products, an industry leader providing reliable, long-term heat insulation and energy saving. Our most popular Celotex insulation, GA4000 100mm, offers our lowest thermal conductivity value at 0.022W/mK.
Mineral wool from Knauf is ideal for cavity walls, as it can be friction fit in place without the need for fixings or adhesive. Slabs of mineral wool are easily knitted together within cavity spaces, preventing any air gaps while being water repellent, rot proof and resistant to mould or bacteria.
Polystyrene is an economic option that offers great value insulation while being environmentally friendly. It’s an especially popular material for floor insulation, where lower thermal conductivity isn’t necessary, and benefits such as moisture and mould resistance, are more important.
