This turnkey project was constructed from SIPS and used Alu clad Rationel windows and doors to provide a maintenance free exterior in combination with the Kiln dried Siberian Larch in profile 4 which will silver down naturally. An EPDM rubber roofing system offers a 35 year solution for this flat roof.
