Applications for Goldfoam XPS Insulation

Underfloor Applications

XPS extruded polystyrene has been used as underfloor insulation in buildings throughout New Zealand. Goldfoam XPS as supplied by Composite Insulation has a wide range of applications for underfloor insulation solutions:

  • Underfloor: Slab on grade, beneath the DPC provides insulation and protection for the DPC during concrete placement.
  • Suspended slabs: provides a thermal break between floors, particularly car parking and in apartments where they may adjoin commercial spaces.
  • Timber floor joists: Installed beneath the joists, therefore, preventing thermal shorts through the timber structure.
  • Slab Edge: Below ground covering thickened slab edge prevents thermal loss to wet or damp ground conditions.

Wall Applications

Goldfoam XPS insulation is extremely versatile and can also be used as a high-performing insulation product for walls. XPS is used in timber and steel stud applications and over building paper in brick and stone veneer preventing thermal shorts through framing. It can also be placed over battens for EIS systems where high compressive strength is a requirement. In blockwork or concrete walls, XPS can be placed between the battens where condensation isn’t absorbed by the insulation.

Additional Applications

Building professionals choose extruded polystyrene insulation for the versatility it offers – it is also used in the following applications:

  • Cathedral roofs - Steel framed roofs,  placed over purlins with additional material placed between purlins prevent thermal shorts through framing.
  • Membrane and tray roofs -  XPS placed over purlins beneath plywood or building paper prevents thermal shorts through framing.
  • Rain screen applications - XPS placed outside in rain screen and creates a high mass wall.
  • Exterior signage - Profile cutters can create a straight edge and the painted element performs well in external locations.
  • Swimming Pools -  Used as formwork for concrete works (spray applied) or external lining (fibre-glass or precast concrete) XPS prevents heat loss to wet ground decreasing running costs of heated pools.

THERMOMASS

Backed by 40 years of experience, Thermomass is the industry leader in concrete sandwich wall technology allowing New Zealand architects and designers to create walls that increase energy efficiency, durability and performance. Thermomass’ concrete insulation systems can be used in plant precast, tilt-up and cast-in-place projects.

MAIN FEATURES OF THERMOMASS:

  1. Proven in New Zealand conditions - used by precasters nationwide for insulating concrete panels during casting.
  2. Insulated from the outside- passively regulating the temperature and reducing energy costs.
  3. Fully tested system -backed by 40 years of experience
  4. The impact of extreme cold and hot conditions is absorbed - due to the storage capacity of concrete.
