Spray Foam Insulation

Agrispray® OS


AGRISPRAY® OS is an HCFC AND CFC FREE two component, 1:1 ratio, rigid foam system which when processed through suitable spray machinery (Graco, Gusmer, Glas-Craft) will produce a rigid foam of approximate density 35kg/m3 with exceptionally good compressive strength. Service Temp range -15oC to 70oC. When tested to BS476 part 7 the foam achieves a Class 1 surface spread of flame.

Benefits or Uses

AGRISPRAY® OS is used for insulation in:

  • Exterior or interior of agricultural buildings
  • Ocean going yachts/canal barges
  • Internal industrial roofing
  • Domestic slate or tiled roofs
  • Crop and animal storage buildings

The benefits of the AGRISPRAY® system are:

  • rapid installation with no mechanical fixings
  • effective high insulation values
  • excellent adhesion to any surface
  • seamless insulation which eliminates unwanted air leakage, saving up to 75% of your energy costs
  • effective surface condensation control
  • fire rated to BS476 Part  7: Class 1
  • provides excellent structural stabilisation
  • recommended for insulation upgrades for existing spray insulation or composite panelled structures
