Vapour Impermeable

Protect A1

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

Protect A1 can be used for all pitched roof constructions (tiled and slated), whether the insulation is at ceiling joist level or at rafter level. It is a twin-ply construction of polypropylene non-woven spunbond layer and PP film.

A1 TYPE HR ROOFING UNDERLAY

  • Completely waterproof.
  • Can be used as a temporary covering.
  • Excellent nail tear strength and tensile strength.
  • Has ‘unrestricted’ use for wind uplift in all exposure conditions in the UK and Ireland.
  • UV and heat resistant.
  • Absorbent undersurface prevents condensate drip-off.
  • Embossed dark grey upper surface reduces glare and takes a chalk line marking.
  • Does not generate noise under wind gusting.
  • Easy to cut, clean, light to handle and unaffected by temperature changes.
  • BM TRADA Independently certified for all applications.

Protect Wunderlay

Protect Wunderlay is a lighter alternative to Protect A1 type HR roofing underlay, developed to overcome the disadvantages of traditional Type 1F and 5U felts and second generation plastic sheet materials.

It has good strength and nail tear resistance and is independently certified by BM TRADA.

Protect Wunderlay provides a secondary line of defence against wind driven rain and snow and resistance to wind uplift.

Being entirely waterproof it can be used as a temporary roof covering.

BENEFITS

  • Completely water and air tight.
  • UV and heat resistant.
  • Good nail tear and tensile strength for it’s weight.
  • Does not generate nuisance noise under wind loading.
  • CE marked and BM TRADA certified.
  • Absorbent under surface prevents condensate drip off.
  • Embossed dark grey upper surface reduces glare and takes a chalk line marking.
  • Easy to cut and handle.
  • Can be used as a temporary roof covering.

Protect A1 T3

Protect A1 T3 is a high performance heavy-duty type HR roofing underlay, developed to overcome the disadvantages of traditional Type 1F and 5U felts and second generation plastic sheet materials.

It has an ultra tough 4 ply construction with heavy-duty non-slip reinforcing grid on the upper surface for maximum damage resistance.

Protect A1 T3 provides a secondary line of defence against wind driven rain and snow and resistance to wind uplift. Being entirely waterproof it can be used as a temporary roof covering during the period the roof covering is applied.

BENEFITS

  • Completely water and air tight.
  • UV and heat resistant.
  • Does not generate nuisance noise under wind loading
  • Excellent nail tear and tensile strength
  • Absorbent undersurface prevents condensate drip off.
  • CE marked
  • Embossed dark grey upper surface reduces glare and takes a chalk line marking
  • Easy to cut and handle.
  • Can be used as a temporary roof covering.
  • Has ‘unrestricted’ use for wind uplift in all exposure conditions in the UK and Ireland.
