PLEKO Therm System modified to enhance protection against any water that may enter the system at various penetrations of the wall. The system is engineered to allow positive drainage of water through specially configured grooves behind the foam. It also provides a secondary weather barrier.

Therm system relevant basecoats, meshes and finishes plus:

WEATHER BARRIER

A Weather Barrier that meets UBC Standard 14-1 for kraft waterproof paper placed between the substrate and the foam.

RUBBERIZED MEMBRANE

A rubberized asphalt and polyethylene membrane, at least 40 mils thick used at all terminations and/or penetrations in the wall system to prevent entry of water.

GROOVED INSULATION BOARD

A proprietary grooved polystyrene insulation board at least 1-1/2 inch thick with a minimum density of min 1.0 pcf.

MECHANICAL FASTENERS

Minimum 1-3/4inch diameter plastic washer with corrosion resistant screws to attach the insulation board to the substrate.

VINYL WEEP SCREEDS AND CASING BEADS

Weep screeds are used at the bottom of the foam and at window and door heads. Casing beads are used around the rest of window and door openings to encase the foam.
