Raises your new build loft floor by 300mm avoiding insulation compression, saving you energy and money.

Loft Leg XL

For New Build Homes


What is Loft Leg XL?


The Loft Leg XL is a unique solution to avoid insulation compression when using your new build home's loft for storage.

Government guidelines recommend that we insulate with 270mm of quit insulation to achieve a U value of 0.16W/m2K (www.energysavingtrust.org.uk). However new build homes can be installed with up to 400mm of insulation to meet stricter insulation targets.

Thermal studies have shown that compressing your insulation can reduce its thermal properties by more than 50%.


A 300mm Loft Leg XL fixed on top of a 100mm truss or ceiling joist provides a cost effective solution. 


Developed by a team of engineers and designers the Loft Leg XL is strong, lightweight and easy to install.


The Loft Leg is manufactured in the UK from recycled polypropylene, to ISO9001 standards and has been mechanically tested by independent experts. 


Installing Loft Leg XL will not invalidate your NHBC Warranty (Click here for more information).
