Marley SIPS

Marley SIPS are made up of a rigid foam PIR (polyisocyanurate) core injected between two structural skins of Oriented Strand Board (OSB) to produce a building panel with excellent load bearing and thermal insulation characteristics. 

Marley SIPS: Panel Range

  • Width: 1250 mm (max)
  • Length: 2500mm or 2800 mm
  • Thickness: 120 mm, 150 mm or 180 mm

Marley SIPS: Other products 

  • L-type wood connectors (used for structural openings)
  • S-type SIP connectors (used to join two SIP panels)
  • Timber bottom plate & top plate

Products not included in the Marley SIP range*:

  • Beams – Solid beams, I-beams, Posi-Joists
  • Roof elements – purlins, ridge beams, rafters, truss or girders
  • Hangers
  • Up-lift elements & tie-down system
  • Shear elements
  • Anchor bolts
  • Nails, screws, screw-nails
  • Breather membrane or Vapor barrier membrane
  • MGO Board (Magnesium Oxide Board) – Available on request

*A list of additional items for your exact project requirements will be provided with the drawings supplied.

PIR Insulation Foam

The PIR rigid insulation foam is factory produced from raw materials and has the following characteristics:

  •  Thermal conductivity λ=0,021 W/m/K
  • U value 0.22w/m2/K (for SIP 120mm)
  • Thickness: 90 mm, 120 mm, 150 mm, 180 mm
  • Density: 46 kg/m3

Rigid insulation is used as solid component insulation in almost every industry for its inherent efficiency and lack of air movement. These attributes are built right into a SIP building. Less air leakage means fewer drafts, less noise, lower energy bills, and a much more comfortable indoor environment. 

Oriented Strand Board (OSB)

The OSB is an “engineered wood” product of the highest quality. The OSB is a biodegradable and sustainable product made from renewable, farm-grown young trees.

 OSB Dimensions

  • 1250mm Width x 2500mm Height x 15mm Depth
  • 1250mm Width x 2800mm Height x 15mm Depth
  • Larger sizes available on request
  • Density : 650kg/m3
