Continuous insulation in the construction environment reduces the risk of thermal bridging that can still occur with traditional cavity insulation. It means that the building benefits from evenly spread thermal protection.
This insulation can be achieved using the right insulating materials that guarantee continuous thermal protection, leading to a more durable and energy-efficient building. Other factors to consider in permanent protection and thermal bridging include reducing air leakage and condensation that usually causes mould, rot and rust.
Thermoplastics are used in continuous insulation, in particular expanded polystyrene (EPS) and extruded polystyrene (XPS), and also polyisocyanurate (PIR) as a thermoset. Each offers varying degrees of energy efficiency depending on thickness, liquid permeance, fire resistance and R-value.
We are going to focus in this blog on EPS and its properties for continuous insulation requirements. Expanded polystyrene foam is a closed-cell material. Polystyrene beads are expanded during the manufacturing process to fit a mould.

EPS is lightweight and easy to install for insulation purposes such as insulating panels and cavity wall insulation. Depending on its thickness, it can be applied outside the structure as a thermal bridging layer, minimising the effects of heat loss and water damage.
Thickness is a critical aspect for thermal bridging because the ideal depth in combination with a superior R-value can guarantee effective thermal insulation. Thickness also affects cladding support and the integration with other structures, doors and windows joists, and floor slabs.
Builders need to use products that meet the construction specifications and guarantee great insulation at a minimum thickness. This fact is essential when installing rigid foam insulation. EPS foam can be installed at different thickness levels to meet the R-value, energy-efficiency and permeability desired for the building design. EPS offers an approximate thermal resistance of R-4 per 25 millimetres of thickness.
Builders should adhere to project specifications and building requirements in their choice of insulating material. EPS is a highly versatile, energy-efficient, lightweight and durable material that meets high-standard building energy ratings, performance and durability.
