ELASTOVAP

ELASTOVAP is a bituminous vapor barrier composed of glass fiber reinforcement and elastomerci bitumen.

Description

The upper face is protected by fine sand and the underside by a thermoplastic film. ELASTOVAP is used as a vapor barrier on common masonry, wood, concrete cell. ELASTOVAP also allows the installation of insulated panels for cold or hot glue. Compatible with many substrates, ELASTOVAP has a thermofusilbe underside easier to weld. Its sanded surface allows a cold bonding of insulation (COLTACK, SOPRACOLLE).

Implementation

ELASTOVAP is implemented by welding propane torch: grip, in Independence (welded joints), semi-independence on perforated screen nailed on wood (welded joints). ELASTOVAP should never be welded on hot bitumen, or by cold adhesive.
