Loft Leg raises your loft floor by 175mm avoiding insulation compression, saving you energy and money. The Loft Leg is a unique design protected solution to avoid insulation compression when using your loft for storage.Government guidelines recommend that we insulate with 270mm of mineral wool insulation to achieve a U value of 0.16 W/m2K.Thermal studies have shown that compressing your insulation can reduce its thermal performance by over 50%.A 175mm Loft Leg fixed on top of a 100mm truss or ceiling joist provides a light weight, ultra-strong, cost effective solution. The Loft Leg is manufactured in the UK from recycled polypropylene and has been rigorously tested to meet and exceed all relevant British and European standards.
