Kingspan OPTIM-R Roofing System is a premium vacuum insulation solution composed of panels with performance five times higher than your standard insulation boards. The vacuum insulation panels are accompanied by rigid thermoset insulation infill panels which can be used where the remaining dimension to infill is below 300 mm or can be cut to fit around problem areas such as penetrations. The panel layout is designed for efficiency ready to suit various requirements especially those with low U-values. 

OPTIM-R Roofing System offers a thermal conductivity of 0.007 W/m∙K. These insulation roofing systems are a next-generation insulation solution thanks to their revolutionary technique and unique insulation properties. The OPTIM-R vacuum insulation boards are resistant to water vapour and don't allow seepage through the roof even in continually damp or rainy environments.

The vacuum insulation board OPTIM-R Roofing System is primarily suited for applications with limited or insufficient space for installing new roof insulation, such as the buildings' ceilings with planning height constraints. This Kingspan OPTIM-R is a modern-day insulation solution to aid in updating older, tight-spaced roofs as well as more modern builds where there is pressure to do more will less space..

Kingspan OPTIM-R Panel Insulation offers a long–term commitment to environmental sustainability and responsibility towards neighbouring communities. More than 90% of its raw material is fully recyclable and non-deleterious.
