Recticel Powerdeck U boards are a specialist high-performance insulation material, designed for the application of warm flat roofs to improve the thermal quality within commercial or residential buildings. This board consists of a polyisocyanurate (PIR) core with each side bonded a bituminous glass fleece facing to improve thermal conductivity. These boards are manufactured using a blowing agent with zero ozone depletion potential (ODP) and low global warming potential (GWP).

The Powerdeck boards are 1200mm by 600mm with thicknesses between 20mm and 150mm with a thermal conductivity between 0.024 and 0.026W/mK. This product is extremely durable and when installed correctly can provide reliable long term thermal performance that will continue to last for the entire lifetime of the building. Powerdeck helps to provide a more temperature-controlled environment meaning warmer winters and cooler summers. The boards provide stability, strengths and the structural integrity allows for the flattest finish. It is lightweight, tough, and easy to handle, cut, and install. A tapered edge form of the Powerdeck U board is also available to assist with roof drainage.

Powerdeck U can be easily cut using a fine-toothed saw by measuring and marking the board and placing the board on a higher surface to allow the saw to cut though. The boards can also be cut with a sharp knife by scoring one side of the board, snapping over a hard edge, and scoring the other side.

Powerdeck U should be stored indoors and on a flat surface. If indoor storage is not an option, ensure the boards are protected with the correct weatherproofing materials. Boards that have been allowed to get wet should not be used. Although the boards are rigid, excess weight and standing on the boards should be avoided as the boards can begin to crumble from the inside due to too much pressure on the boards core.

Correctly insulating your home or office space can mean saving you money on up to 30% of your energy bills whilst creating a more sustainable environment. By reducing the heat levels escaping your property, you are contributing to the reduction of climate change and global warming.
