Why choose liquid roofing?
A liquid polyurethane coating system is a layer (type of polymer) that is applied and protects base material from weathering, abrasion and corrosion. The system normally is a single or a twin pack that may have fleece or fibreglass matting and is installed ‘Wet on wet’. As this product has progressed the liquid has now become odour free, and is ideal for projects on offices, schools, hospitals and other sensitive areas.

Cold Vs Warm Roof
In construction flat roofs are detailed as either warm roofs or cold roofs.
Warm roof
When the insulation layer is laid on top of the roof substrate or deck we call this a warm roof. This is because the roof structure and substrate are on the warm side of the insulation.
Cold Roof
When the insulation is fitted between the rafters / structure and the roof substrate or deck is fitted above the insulation it makes the roof a cold roof structure because the substrate is on the cold side of the insulation.
Do you need a warm or a cold roof?
To comply with Part L of the building regulations 2010, all roofs to rooms (except those in unheated buildings) should be thermally insulated to a maximum U-value of of 0.18
For more information on warm and cold roof construction, as well as Part L Building Regs, please see the following page – A guide to warm roof construction.
