Unimat Façade Ultra Opti 141 mm – Siniat graphite-coated EPS external wall insulation panel, R=4.40

Unimat Façade Ultra Opti 141 mm Siniat – PSE external wall insulation, R=4.40

Graphite-enhanced EPS insulation offering the best value for money

The Siniat Unimat Façade Ultra Opti panel, 141 mm thick, is a rigid graphite-modified expanded polystyrene insulation board, designed for external wall insulation beneath render. Positioned as a cost-effective alternative to the Ultra BD range, it retains the thermal properties characteristic of graphite-enhanced EPS, with a grey colour that improves performance compared to conventional white EPS of the same thickness. Measuring 1200 x 600 mm, this panel has a thermal resistance of R = 4.40 m².K/W, thanks to an ACERMI-certified thermal conductivity of 0.032 W/(m·K) (class TH32). Whilst this performance is slightly lower than that of the Ultra BD range (TH31), it enables us to offer a competitive price whilst maintaining a good level of thermal insulation. Lightweight and easy to cut, this panel is installed by gluing and/or fixing with dowels to masonry or concrete substrates, in accordance with the specifications of the ETICS system covered by the approved technical assessment, and is just as easy to install as the other products in the Unimat Façade range. Manufactured by Siniat, this panel meets the regulatory requirements applicable to all types of buildings: detached houses, blocks of flats or commercial buildings, in both new builds and refurbishment projects. Facade contractors and external thermal insulation contractors will find this panel to be a reliable, certified and cost-effective solution for their external thermal insulation projects on a controlled budget.
