Installation Recommendations

Delivery and Site Handling

Rolls of Proctor Profoil are delivered to site with tape identifying the product grade or membrane, or overprinted, clearly identifying product name and grade. Rolls should be stored flat or upright on a clean, level surface and kept under cover.

Weather Conditions

Laying lightweight membranes in high wind conditions is difficult and appropriate precautions should be taken during installation.

Preparation of the Base

Before installing the vapour control layer ensure that the surfaces to be covered are firmly fixed, clean, dry and smooth.

Laps

Lay the Proctor Profoil vapour control layer loose, flat and without wrinkles. Laps should be preferably sealed with two continuous runs of 15mm wide Probond RG tape. The minimum width of a lap should be 150mm. Adhesive PVC should not be used for sealing and jointing laps in vapour control layers.

Puncture Damage

Where puncture damage is unavoidable, apply good sized patches over the puncture, ensuring that there is a continuous bead of tape all the way around the hole. For small scuff type damage of less than 25mm as an alternative Proctor Probond Flex Tape may be used.

Details

Attention to detail is important. Proctor Profoil needs to be continuous and particular care is required sealing around penetrations and at the perimeters where roofs and walls meet.

Preferred Details

Built up metal roof / metal side cladding

Key point to watch:
Ensure Vapour Control Layer is continuous and all laps and penetrations are sealed effectively.

Key point to watch:
The lap between the vapour control layers should be sealed with two continuous runs of 15mm wide Probond Tape.

Key point to watch:
1. The vapour control layer in the wall needs to be effectively sealed to the vapour control layer in the roof.

2. The roof breather membrane drains freely into the gutter.
