WALL-GUARD is an extruded polystyrene rigid foam with an integral high density skin and homogeneous closed
cell structure manufactured according to ASTM-C578 or BS 3837 Part 2, specs and possesses the
following typical properties. WALL GUARD boards are significantly reduces energy loss through
external wall of buildings as it has low thermal conductivity and its closed cell structure made it high
resistance to water absorption, WALL GUARD is available in wide range of thickness to meet different
Density : 28 – 30 Kg/M³
Board Size : 1250 x 600 mm (or requested lengths)
Thickness : 20, 30 40, 50 60, 70, 80, 90 and 100 mm (or requested)
Edges : Tongue & Groove or Shiplap (rebated)
Application : Cavity wall insulation, Interior or Exterior wall insulation, tiles backing.
THERMAL CONDUCTIVITY(K-VALUE) : 0.029 W/MK OR 0.20 Btu.In/Ft² h °F (At 24 °C; 50 °F)
COMPRESSIVE STRENGTH(AT 10% DEF) : 220 - 250 KPA OR 31 - 36 PSI
WATER ABSORPTION : 0.2% by volume (±)
WATER VAPOUR PERMEABILITY : ≤ 1 PERM-INCH
WALL-GUARD Board is specially designed for Interior Wall Insulation, Exterior Wall
Insulation and Cavity Wall Insulation with rebated edges on all four sides,
to eliminate thermal bridging. Hence, it is cost effective, easy to install and
reduces loss of time
CAVITY WALL INSULATION
Cavity wall insulation is required for air conditioned building to control temperature.
Cavity wall is an advantage where exterior brick finish is required.
INTERIOR WALL INSULATION
Interior thermal insulation is being used for existing buildings and could be used for new building.
EXTERIOR WALL INSULATION
Exterior insulation can be installed either behind panels of marble or granite panels. WALL GUARD boards
shall be fixed to external walls using using either plastic dowel or with compatible solvent free adhesive.
