Puren® GDS
Tapered boards are designed to create a slope on a flat roof. The minimum board thickness is 20 mm. Board format is 1200×600 (1000×500) mm. The slope of the boards depends on the customer's requirements or order. Lay the boards as the first layer (beneath the flat board) with overlapping joints. The three-board system for creating the slope, in thicknesses of 20/40, 40/60 and 60/80 mm and a length of 1200 (1000) mm, repeats, so that the next three-board system is backed by a three-board system of flat puren MV boards, 60 mm thick (blunt edge).

purenit®
purenit functional boards are designed to reduce or eliminate thermal bridges in building structures, to anchor roof elements to the sealing layer (rooflights, ventilation equipment, etc.), and to build parapets on flat roofs, among other uses. The surface can be laminated with various surface materials or covered by bitumen welding. Purenit is resistant to a range of chemicals and can be bonded with different materials. It offers guaranteed moisture resistance without swelling and minimal moisture absorption with no change in dimensional stability. The boards can be cut to length and width with standard woodworking tools (e.g. a saw), and can also be drilled with standard wood bits. Direct fastening into purenit itself is not possible.
