Insulate your home without compromising on storage space by using Loft Legs to raise the loft floor by 175mm for energy efficient loft storage This product raises the loft floor by 175mm on top of ceiling joists, ensuring insulation is not squashed and U values are maintained.  Dimensions Length: 175mm. Width: 76mm. Coverage is approximately between 1m and 3.2m. Please note this product is not suitable for habitable rooms as the product is designed to fit on top of ceiling joists in boarded lofts used as storage. Features Compressed loft roll insulation can compromise thermal performance and reduce the energy efficiency of your home. Loft Leg raises the height of a storage deck by 175mm on top of ceiling joists, to prevent compression of loft roll insulation, maintaining U values. Compressed loft roll insulation can compromise thermal performance and reduce the energy efficiency of your home. Loft Leg is strong, lightweight and easy to install. Manufactured in the UK from recycled materials and complies to ISO9002 standards. Loft Legs are designed for domestic use only and are not intended for use as a flooring substrate or surface in a permanent living space. Loft Legs are strong and can support weights of 500kg however, they do not change the load bearing characteristics of a loft. Structural engineers recommend never storing more than 50kg per square metre of boarded area. Loading limit of existing ceiling structure should be confirmed by a structural engineer. We recommend Wickes Ultra Gold Screws 4.0x40mm PK200 (SKU 511089 ) for better performance.
