Easy-Trim Roofing and Construction Products Ltd Variant:

BBA-approved breathable roofing felt with integrated tape. 112 GSM. Integrated version is suitable for all wind zones.

Jump to:
01282 930680 Website

Application

Suitable for:

  • Warm, cold and hybrid roof applications.
  • Scottish sarking boards.
  • Timber & metal framed constructions.
  •  Fully supported or unsupported installations.
  • Tiled or slate pitch roofs.

Description

High performance roofing membrane that is vapour permeable, water resistant and airtight. They allow vapour to escape from the inside whilst repelling rainwater from the outside, helping to minimise condensation in the roof space. 

The membranes are available with or without integrated overlap tap.


Weight: 112 GSM


Features and Benefits:

  • Excellent tensile strength / tear resistance.
  • UV Stable for 3 months.
  • Superior 3-layer bond system.
  • Printed cutting grid minimising waste.
  • Available with or without integrated overlap tape.  
  • Wide range of weights available.
  • Available in 1m or 1.5m lengths.
  • Integrated tape allows for faster installation.
  • Integrated tape membranes are suitable for use in all five wind zones.



Quality Standards:

  • BBA certified for warm and cold roof applications BBA 10/4753.
  • Complies to all Wind Zones 1-5.
  • Conforms to BS 5534.2014 Annex A.
  • Type LR Underlay to BS 5250.


Wind Zone Suitability

The wind uplift resistance figures for Easy-Trim breather membrane applies in the geographical wind zones stated on the datasheet, where a well-sealed ceiling is present and the roof has a ridge height of ≤15m, a pitch between 15° and 75°, and a site altitude of ≤100m, and where the topography is not significant.


The required uplift resistance for other roofing projects should be determined using BS 5534: 2014 +A1: 2015 and the declared wind up lift resistance which can be made available through our technical department.
