STRATACON SA
Vapour Control Layer
Stratacon SA is a polyester reinforced roofing base layer, saturated and coated with high quality SBS (StyreneButadiene-Styrene) modified bitumen. The membrane is protected with fine grained sand on its upper layer, whilst the bottom layer features a self-adhesive compound coating, covered with removable film.
Advantages
- Cold-applied, self-adhesive application
- Ideal for flame-free installations
- Easy-peel removable film
- Tough polyester reinforcement, providing additional dimensional stability and mechanical strength
- Good resistance to foot marking
- Excellent low temperature flexibility at -15°C
- Versatile roofing membrane - compatible with a range of substrates and built-up roofing systems
- Manufactured in accordance with EN 13707 + A2:2009 European Standards and testing methods.
Usage
- First layer in torch-bonded built up roofing system
- Protection layer against moisture vapour migration.

Product Specification
Rolls must be vertically stored in roofed-over spaces. If the rolls have to be stored outdoors for a long period of time, then they must be covered with a protective layer in order to protect them against the sunlight. If the rolls are to be stowed without pallets, they are not stacked one on top of another. Shelf-life is one year from the production date in case it is stored in its sealed and undamaged package in dry ambient conditions at a temperature from +5°C to +25°C away from direct sunlight.

Applications Back to top
The Stratacon SA membrane should be laid out in the required direction of work. Please note that on sloping roofs, the self-adhesive membrane should be laid out from the bottom, perpendicular to the slope direction.
To install the Stratacon SA membrane, the siliconerelease foil on the lower surface should be peeled off as work proceeds so that the self-adhesive compound on the membrane underside can be firmly bonded to the substrate. During application, ensure that there is a 15 cm overlap margin on all short side overlaps of 1 meter, and there should be a 10 cm overlap for all long side overlaps. At all times, we recommend that this product is installed in accordance with the NFRC’s Safe2Torch guidelines.
