Product Description

Technoelast VB500 is a cold-applied, self-adhesive vapour control layer. Technoelast is coated with a high quality SBS modified bitumen. The aluminium lined, foil face vapour control layer helps to control condensation and ensure optimum performance of roofing system components.

Questions & Answers

Question:

Hi, what's the overlap required when laying this on a ply deck flat warm roof please?

Answer:

We would advise to install with at least a 200mm overlap.

Question:

My garage roof is metal box profile sheets. Can this product be applied directly to the underside of the roof sheet? In this way, will this product contain condensation? How and when will the condensation be released?

Answer:

Condensation forms where the cold and hot air meet, so really to reduce this you need to be insulating the roof not just applying a membrane.

Used this product on a warm flat roof as first layer. It was very easy to roll out and stuck down no problems.

The vapour barrier is very robust and does exactly what it should! My choice was not to use the primer as it was being held in place by the insulation and osb above! If you require good rather than minimal adhesion then use the primer.
