The building includes several small roof-top balconies, which are above heated spaces and offer an extension to the living areas. Installers at Youngs Roofing noted that “the need to retain low threshold heights whilst meeting the demanding U-value of 0.14 W/m2.K provided a challenge” for this project. The Kingspan OPTIM-R E Roofing System offered the perfect solution.
Kingspan OPTIM-R E comprises a vacuum insulation panel, Kingspan OPTIM-R, completely encased within a high performance PIR insulation board. With an ultra-slim 80 mm thick design, it delivers an outstanding thermal conductivity of 0.009 W/m.K.
The encasing PIR insulation board provides complete protection for the vacuum insulation panel, allowing fast installation. Utilising Kingspan OPTIM-R flex infill strips, of the same thickness, enabled installers to easily infill awkward spaces and accommodate penetrations through the insulation layer.
