Bayonet BayoWrap Wall Underlay is a synthetic building underlay for use as a flexible wall underlay under wall claddings on timber and steel-framed buildings.
Use as a synthetic alternative to traditional building paper under wall claddings to reduce drafts and assist with moisture management. Its unique beige colouring significantly reduces glare too. BRANZ has appraised the use of BayoWrap Wall Underlay in all areas and all conditions including timber and steel framed buildings, with absorbent and non-absorbent wall cladding both direct and cavity fixed. Available in rolls the full height of the walls, it makes the job of fitting quicker and more cost effective overall.
