Steico Protect Dry is a natural render/plaster carrying wood fibre insulation board with a tongue and groove profile manufactured in accordance with EN 13171.

Designed both as an external sheathing board for timber frame constructions or for direct to masonry applications in external wall insulation systems, where the render is applied directly to the board and, as an internal plaster carrying board for direct fixing to timber frames without the need for a supporting backer board.

It is quite common for architects and designers to specify Protect DRY boards in certain building applications and in combination with a separately specified finish or render system.
