Marley Ltd
Marley Type A brown batten: preservative brown treated to Use Class 2. Marley states explicitly that it is NOT suitable for BS 5534 applications and that JB Red is the graded batten to use for roofing. This is the distinction that decides whether a batten is legal to tile onto, and it is not visible on site once fitted.

Marley Ltd
Marley Universal 10mm Roof Eaves Ventilation System provides a continuous 10mm free vent area to the roof void, sized for lower pitched roofs with deeper insulation. It compresses the insulation at the eaves to preserve airflow, allows clip fixing of all tiles at the eaves, and prevents ponding on the underlay behind the fascia board and wildlife ingress. Meets BS 5534 requirements and NHBC guidelines. Fascia or tilting fillet height must be checked against the tile type and rafter pitch, allowing for the over-fascia ventilator and comb filler strip.

Marley Ltd
Marley Universal 125 vapour permeable roof underlay: water vapour resistance Sd 0.029 m (+/-0.01) tested to EN ISO 12572, water penetration Class W1 to EN 1928 before ageing. Lighter 125 gsm grade sitting below the 170 gsm Universal underlay in the same range.

Marley Ltd
Marley Universal Dry Verge, a mechanical alternative to a mortar bedded verge. Works over a 12 to 55 degree roof pitch range (up to 55 degrees). Compliant with BS 5534 as a means of mechanically fixing verge tiles and with NHBC guidelines; each unit gives the stepped appearance of a traditional mortar bedded verge.

Combined with the Universal eaves vent systems it gives eaves-to-abutment ventilation. Meets BS 5534 requirements and NHBC guidelines.
- supplier figure RN-PWPUW8
Marley Ltd
Marley Ventilated Dry Ridge System, a mechanically fixed and ventilated alternative to mortar bedded ridge tiles. Suitable for roof pitches up to 55 degrees and meets BS 5534 requirements, which since 2014 has required mechanical fixing of ridge and hip tiles rather than mortar alone.

Marley Ltd
Marley western red cedar shingles: 400mm long with random widths 75mm to 350mm, 10mm thick at the butt tapering, minimum pitch 14 degrees, fixed to 38mm battens. Gauge, coverage and laid weight change sharply with pitch. At 75-90 degrees (vertical cladding) maximum gauge 175mm, 3.20 m2 covered per bundle, laid weight 4.0 kg/m2, 5.3 lin.m/m2 of battens. At 22-74 degrees maximum gauge 125mm, 2.28 m2 per bundle, 6.1 kg/m2, 8.0 lin.m/m2 of battens. At 14-21 degrees maximum gauge 95mm, only 1.73 m2 per bundle, 8.1 kg/m2, 10.5 lin.m/m2 of battens. Dropping from a 30 degree roof to a 15 degree roof therefore costs roughly a third more shingles and battens.
