Reliable lightweight vapour permeable membrane!

Lightweight hybrid breathable roof underlay provides excellent performance, whilst being flexible and only 100gsm. BBA certified and suitable for both fully supported and unsupported installations in tiled or slate pitch roofs.

The Grafter 100 is a 3-layer micro porous breather membrane, which features a microporous film that is thermally bonded between two spun-bonded polypropylene layers. Allows the roof to breathe, so eliminates condensation, whilst providing secondary protection against rainwater ingress. Easy-Trim breather membranes improve energy efficiency and minimise the wind uplift that can loosen slates and tiles.

Features & Benefits

Reduces condensation in roof - highly vapour permeable
Driven rain and snow protection - second line of defence
Highly versatile - use on warm, cold and hybrid roofs
Flexible yet strong - good tensile tear strength
UV stable for 3 months - protection during construction
Quality you can trust - independently tested
Superior water resistance - protective polypropylene top layer
Printed with brand and cutting grid - easier to identify and fit
Choice of roll size - 1m or 1.5m widths and 20m or 50m length

National Wind Zone Suitability

New builds must comply with British Standard for Tiling and Roofing (BS5534) Annex A, with breather membranes tested against wind uplift, and their suitability for use across the 5 national wind zones.

Fitting & Usage

Preparing a roof with Easy-Trim Grafter 100 Breather Membrane

Fitting of Easy-Trim breather membrane should begin at the lowest level of the roof, at the eaves, with the printed side facing out. Starting from the left, roll the membrane horizontally across the rafters to the right, and be sure to allow 100mm lap over the felt-support trays. The use of double-sided overlap tape to secure the lower edge to the felt-support tray is highly recommended.

Roof Pitch	Horizontal Laps		Vertical Laps
Roof Pitch	Not Fully Supported	Fully Supported	Vertical Laps
12.5 to 14°	225	150	100
15 to 34°	150	100	100
35 to 75°	100	75	100

Horizontal laps in breather membrane should be taped with the double-sided overlap tape, or battened over. Whenever possible, horizontal laps should coincide with the closest tiling or slating batten. Vertical laps should be positioned over a rafter and have a minimum of 100mm lap.

Easy-Trim breather membranes are suitable for installations on all major pitch roofing and timber frame applications, and must be installed in accordance with our fixing instructions, complying with the recommendations of BS5534: 2014 + A1: 2015; BS5250: 2011 and BS8000-0: 2014 and any other applicable standard. The products are designed to be installed by competent and experienced installers of slates and tiles.
