SRS Self-Adhesive VCL PR100SA
PR SELF-ADHESIVE VCL is a cold-applied, self-adhesive bituminous vapour control layer which is saturated and coated with high quality SBS (Styrene-Butadiene-Styrene) modified bitumen.
It has an integrated aluminium foil layer, a glass fibre reinforcement and is finished on the underside with a removable siliconised film.
PR SELF-ADHESIVE VCL is designed for use as a high performance vapour barrier, and is ideal for use on either metal profiled or plywood decking and in areas prone to increased temperatures and moisture levels (e.g.factories, swimming pools, gyms).
Product Features
- Flame free, self-adhesive application
- Tough, mechanically resistant membrane
- Simple, fast installation
- Low temperature flexibility at -25°C
- Aluminium lined
Application
PR Self-Adhesive VCL should be installed in accordance with manufacturer recommendations and all relevant national standards and codes of practice, including BS 8217: 2005 - the code of practice for reinforced bitumen membranes for roofing.
Roofing contractors should also be fully conversant with the guidelines set out in the National Federation of Roofing Contractors (NFRC) 'Safe2Torch' campaign.
If hot air guns are used during application, operatives should be competent, conversant and capable of using such items in a safe and responsible manner.
Care must also be taken when using hot air guns in close proximity to combustible materials, decorative coatings and heat sensitive materials.
In order to install the Self-Adhesive VCLmembrane correctly, ensure that the surface is dry, free of oil, fat and dust and other impurities.
The membrane should be unrolled, aligned and set into position alongside other rolls and profiled decking. Once aligned, one end of the siliconised film should be peeled back. The edge of the Self adhesive membrane can then be pressed to the profiled decking substrate.
The product should then be unrolled on to the deck whilst simultaneously pulling off the siliconised film.
Chemical Resistance
Self-Adhesive VCL is water-resistant and is resistant to watery solutions of salt, diluted non oxidising acids and bases. Aliphatic and aromatic hydrocarbons , as well as chlorine hydrocarbons , oils and greases may loosen the product and should therefore be avoided.
Storage
Store in a cool, dry place and protect from direct sunlight.
Health and Safety
Health and Safety should be observed at all times in accordance with HSE and industry guidance. Specific Risk Assessments and Method Statements should be produced by contractors where necessary to ensure Working at Heights, Fire Safety and Manual Handling rules are compliant with current law and regulations. Health and safety data sheets are available for all materials on request from our Technical Service Department.
