XPS Insulation
XPS insulation is a rigid foam board made through an extrusion process that creates a dense, closed-cell structure. This manufacturing method gives XPS its standout qualities, like consistent thermal performance, exceptional durability, and superior moisture resistance. Unlike expanded polystyrene (EPS), which is formed from individual beads, XPS is a continuous, uniform material. That’s why it delivers higher long-term R-values and performs reliably across a wide range of building applications, from slab insulation to walls, roofs and underfloor systems. If you’re looking for insulation that can handle pressure, moisture and temperature changes without losing performance, XPS is hard to beat.
One of the XPS products we supply is a 25mm board measuring 600mm x 2400mm (covering 1.44m²), offering an R0.81 thermal value and a compressive strength of 250–350 kPa. Its square-edge profile makes it easy to install in both residential and commercial projects, and the high-density 32–36 kg/m³ structure ensures it stays rigid and stable over time. Because XPS is impervious to water, it won’t absorb moisture or break down, even in damp soil conditions, making it ideal for slab edges, perimeter insulation and trench applications. For estimating, many builders use the common rule of thumb of deducting around 25% of total area for trench setups, and our team is always happy to help calculate what you’ll need.
