Hunton Sarket underlay board 18x595x2420 mm, 11 pcs (NOTE: TONGUES BROKEN ON SOME BOARDS!)

Underlay and wind protection are combined in the Hunton Sarket™ underlay board. The board is a porous wood-fibre board impregnated and coated with bitumen.

With Hunton Sarket™, the roof structure is ventilated only above the underlay. Hunton Sarket™ is 18 mm or 25 mm thick. The boards have tongues and grooves on all sides, making installation easier.

The board is used in insulated timber-framed pitched roofs. The roof pitch must be at least 1:3 (approximately 18°). The board is well suited as an underlay beneath discontinuous roof coverings or continuous sheet coverings where moisture may condense on the underside of the roof.

Examples of such roofs include concrete roof tile and corrugated steel sheet roofs.

Hunton Sarket™ is particularly well suited as an underlay for roofs with continuous thermal insulation from ridge to eaves. The board is also suitable for roofs with an unheated attic space beneath, where thermal insulation is to be installed below the roof covering at a later stage. The insulation can be installed directly against the underlay.

TECHNICAL INFORMATION

• stores moisture

• breathable

• provides thermal and acoustic insulation

• tongue-and-groove on all sides

• easy to work with

• use: as an underlay and wind protection board in ventilated pitched-roof structures

Hunton Sarket™ underlay board cannot be used on tiled roofs without a standard double water-lock groove, or on water-permeable roofs such as shingle or wooden-shingle roofs.

The board is made from natural raw materials. The main raw material is spruce chips sourced from PEFC™-certified forests in Norway.

Hunton Sarket™ wood-fibre board has a certificate issued by VTT.
