WallBan extruded polystyrene boards will prevent the loss of energy through
external walls of buildings.
WallBan is good for both internal insulation as well as external insulation, which provides support to any finishing works such as plastering, dry lining and rendering.
CHARACTERISTICS OF WALLBAN
- Density: 30 – 32 kg/m3.
- Board size: 600 x 1250 mm.
- Thickness: 25, 30, 40, 50, 60, 70, 75, 100 mm.
- Edges: Rebated edges or straight.
INTERNAL WALL INSULATION
Internal Wall Insulation type involves applying a 30-50 mm insulation layer on the inside of walls covered with Composite board ( gypsum board + WallBan ) fixed with adhesive and possibly metal fasteners.
EXTERNAL WALL INSULATION
The design and installation of external wall insulation is a specialist job. It is strongly recommended to use certified materials and components. The typical method includes attaching standard size insulation boards to the wall and finishing with a reinforced render or cladding.
CAVITY WALL INSULATION
Many constructions are built with cavity walls. There is an outside wall and an inside wall with a gap between the two walls. This gap will be filled with XPS insulation boards.
