Impermeable (Type HR) Roofing Underlays

Protect A1 is a ‘third-generation’ roofing underlay developed specifically to overcome the disadvantages of traditional Type 1F felts and second-generation plastic sheet materials.

A1 can be used for all pitched roof constructions (tiled and slated), whether insulation is at ceiling joist level or rafter level.

All our roofing membranes are independently certified with the BRE in accordance with both the Northern Ireland and Republic of Ireland Building Regulations.

A1 benefits include:

1. Being completely waterproof
2. Can be used as a temporary roof covering for up to three months before the roof covering is laid
3. Excellent nail tear and tensile strength
4. Easy to cut, clean and light to handle
5. Unaffected by temperature changes
6. Proven time saving over 1F felt
7. Unrestricted use for wind uplift in all exposure conditions in the UK and Ireland
