U-VALUE CALCULATION

The U-value of the KORE Lock System is only limited by the depth of insulation installed. The more insulation that is installed the better the U-value achieved. Contact Airpacks technical department for further U-value calculations.

INSTALLATION

KORE LOCK COLD ROOF

Airlock Cold Roof Application_02_edited-1.jpg

Commence by fitting the KORE Lock variable width panels between each rafter, following completion of cold cladding, keeping panels flush with the underside face of the rafter and closely butted at the ends.

Ensure the necessary clear 50mm air space between the insulation and the sarking felt is maintained. If an approved breather membrane is used as a tile underlay the requirement for the 50mm air space may be ignored and filled with insulation.

Fix the first row of KORE Lock Panels to the roof line at the junction with the vertical stud walls, beginning with the first slot. Secure in place by nailing through batten and insulation into the rafters. Repeat the procedure until the entire area is insulated.

Continue installing of KORE Lock Panels to vertical studding and ceiling collars to completion.

Apply KORE Linear Drylining panels to the underside of the rafters with suitable fixings, ensuring joists are tightly sealed. Face with minimum 500 gauge polyethylene vapour barrier.

 

KORE LOCK WARM ROOF

Commence by fitting KORE Lock variable width panels between each rafter, keeping panels flush with the upper side of the rafter and closely butted at the ends.

Place the KORE Linear Panels on top of the rafters ensuring joists are tightly sealed.

Secure the panels by fixing the appropriate sized counter battens through the panels to the rafters,

Lay an approved weatherproof breather membrane over the counter battens. Allow the membrane to sag as normal between the battens. This will facilitate proper drainage and ventilation.

Fit tiling battens to the rafters and tile the roof in accordance with BS 5534.

On the underside of the rafters fit an appropriate vapour control layer and plasterboard sheets.
