Masons VHP Value Roof Underlay

Product Description

Top Performance, Self Supporting, Great Value

VHP Value is a high performance, self-supporting, highly breathable, tough, synthetic roof underlay. A huge upgrade from Bituminous Paper.

3 pliable layers: a very high vapour permeable water-resistant membrane and two tough layers of non-woven polyolefin fabric. These layers assist in the control of condensation and water vapour. VHP Value Roof Underlay is not fire retardant.

It has the following benefits:

• Premium performance
• Assists in moisture control - deflects water and air both during construction and as part of the finished roof
• AffordableSelf-supporting
• Highly breathable - transforms water vapour at higher rates than bitumen impregnated paper
• Temporary weather protection - UV resistance for 21 days - although same-day coverage is strongly recommended
• Codemark Certified 

Intended Use

Masons Roof Underlays are for use as a self-supporting roofing underlay.
