Choose your thickness
A rigid foam polystyrene board, EXPOL-X provides solid insulation for exterior masonry walls. EXPOL-X exhibits excellent water tightness qualities making it ideal for exterior applications and is available in full sheets (2500mm x 600mm). For interior applications, choose EXPOL Platinum Board.
EXPOL-X is also used in other applications where compressive strength, water resistance and superior R-value are required. This includes under concrete floors, perimeter insulation on concrete edges, in cladding systems and in retaining walls.
MORE ABOUT EXPOL-X
EXPOL-X polystyrene insulation sheets are highly water resistant and provide an extremely high insulation value. The durable nature of extruded polystyrene ensures that the R-value of the material is retained for the life of the building.
A thin, lightweight insulation board, EXPOL-X is preferred by installers because it is easy to handle and quick to install. Specifiers looking for a product that offers excellent performance for a range of uses in diverse climate conditions turn to EXPOL-X.
EXPOL Wireguard is a waxed paper strip for separating exposed electrical cables from EXPOL insulation. An important part of the system, EXPOL Wireguard prevents the degrading effect that EPS can sometimes have on electrical cables over a prolonged period.
EXPOL supplies a water-based glue to adhere polystyrene to most surfaces. EXPOL-X cladding insulation is glued in place using this adhesive or can be used in combination with other fixing methods.
HOW MUCH DO I NEED
CHOOSING THE RIGHT PRODUCT
EXPOL-X comes in one size; 2500mm x 600mm wide.
CALCULATING HOW MUCH PRODUCT YOU NEED
EXPOL makes insulating easy. To ensure you get the best result, follow these simple steps.
To install EXPOL-X, first ensure sheets are cut accurately to create a snug fit between timber batons or strapping.
Spot glue EXPOL-X to hold sheets in place until lining materials are fixed. Care should be taken to ensure there is no contact between EPS boards and electrical wiring.
Because of its superior water tightness, EXPOL-X is normally used for exterior applications. EXPOL Platinum Board is designed for interior applications and also achieves a superior R-value for thermal insulation.
Is EXPOL-X durable?
The closed cell structure of EXPOL-X gives it resistance to moisture and compression, ensuring that insulation performance will last the lifespan of the building. Extruded polystyrene insulation (XPS) is often used under roads, rail tracks and other load-bearing applications.
What size does EXPOL-X come in?
EXPOL-X comes in 2500mm x 600mm sheets, with varying thicknesses available.
How does EXPOL-X compare to EPS insulation boards?
When used as interior insulation, EXPOL-X provides greater R-value and compressive strength than EPS insulation boards.
How does EXPOL-X contribute to a building’s energy efficiency?
EXPOL-X demonstrates excellent thermal insulation properties when used in hot or cold climates. The insulation helps maintain a more constant indoor temperature reducing the consumption of energy used for cooling or heating.
