EPS-R960-I
Expanded Polystyrene
50 / 75 / 100 / 150 / 200 mm
960 / 1000 / 1150 mm
From 6.5 kg/m²
Class B1 / B2
Expanded polystyrene foam delivers solid insulation performance at the lowest cost per square metre. Closed-cell structure resists moisture and won’t sag, settle or compress under self-weight.
At 6.5 kg/m² (50 mm), EPS panels are the lightest option in our range — ideal where structural payload, transport cost or remote-site handling is a concern.

EPS-R960-II
Expanded Polystyrene
75 / 100 / 150 / 200 / 250 mm
1000 / 1150 mm
From 9.5 kg/m²
Class B1 / B2
Expanded polystyrene foam delivers solid insulation performance at the lowest cost per square metre. Closed-cell structure resists moisture and won’t sag, settle or compress under self-weight.
At 6.5 kg/m² (50 mm), EPS panels are the lightest option in our range — ideal where structural payload, transport cost or remote-site handling is a concern.
All Vikkins EPS panels use B1-grade FR-modified core. The foam is self-extinguishing on flame removal and will not sustain combustion — meets GB 8624 B1 and EN 13501 E classifications.
Recommended for non-public-occupancy buildings: warehouses, prefab housing, livestock and agricultural applications. For higher fire requirements, see our PU/PIR or Rockwool panels.
GWR panels feature an integrated polyurethane side seal that closes the cut-edge of the glass wool core, preventing fibre release, water ingress and edge crushing during install — a key advantage over plain mineral wool panels.
Two stock profiles available — VK-GWR1 (single-step trapezoid) and VK-GWR2 (double-step low profile) — selected by aesthetics or required deflection.
