Loft Insulation

On average a quarter of heat is lost through the roof in an uninsulated home. Installing insulation in your loft, attic or roof is a simple yet effective way to significantly improve your home’s energy performance and reduce heating costs.

Insulation UK offers a wide range of loft insulation options to suit every project and budget, from easy-to-lay loft rolls and foils to insulated loft boards, which combine the strong and sturdy qualities of OSB boards with the high-performance qualities of PIR insulation. Choose from reputable brands like Knauf, Rockwool and Tekwarm, offering exceptional quality for an affordable price.

Loft Roll Insulation

The most common form of loft insulation is loft roll. Available in a variety of thicknesses from 50mm to 200mm, the standard loft roll has perforations to ensure it fits between standard  joists and reduces the need for measuring. Here at Insulation UK we offer major brands such as Knauf Loft Roll 44, Superglass Multi Roll and our sustainable range from Thermafleece includes the CosyWool range - made from 75% British Sheeps Wool and the SupaSoft range made from recycled plastic bottles.

Between Rafter Insulation

Designed for insulating the rafters in your loft , there is a variety of loft insulation materials available. The Knauf Rocksilk or the Rockwool RWA45 ranges are ideal, coming in a variety of thicknesses and a low thermal conductivity of 0.035 W/mK, these mineral wool slabs are not only an ideal way to insulate your loft rafters but also offer great acoustic properties and are fire resistant. 

Loft rafter insulation, is also known as pitched roof insulation  and the Kingspan K107 is an ideal solution for attic conversions and renovations. This phenolic insulation, offers excellent thermal properties, resists sagging and is lightweight and easy to install.

Our own range of pre-cut insulation in widths of 400mm and 600mm  is a cost effective way of insulating loft rafters. Ranging from 25mm to 100mm in thicknesses these PIR strips are made from Recticel insulation.
