As you’re probably well aware, at Roofgiant we’re always hunting for new and exciting products! We’re delighted to announce three new additions.


Earthwool loft roll 44 is available in a range of thicknesses with a thermal conductivity of 0.044 W/mK. It’s made of glass mineral wool and is designed to be used in pitched roofs at ceiling level. 

Combi-cut products have partially cut perforations, providing the flexibility to be used between joists at either 400mm or 600mm centres, or used unsplit as a full-width roll. While ready-cut products are fully cut and are designed to be used between joists at 600mm centres. 

You’ll be glad to know the lightweight quilt means it’s easy to install and it’s achieved Euroclass A1 non-combustible status.

Tyvek® Supro is a durable, water-resistant membrane that is reinforced with a laminated polypropylene nonwoven. 

This airtight, vapour-permeable membrane is extremely water-resistant and can be used for all supported and unsupported pitched roofs.

Tyvek® Supro does not need any soffit, tile or ridge ventilation, which can save time and money in the construction process. In addition to warm, hybrid and cold roofs, applications include Scottish sarking board systems, low-pitched metal roofs, and wall and floor applications.
