Stylite Plustherm insulation contains graphite which considerably increases insulation performance and the reaction to fire rating. It can be used in a wide variety of floor applications, both for domestic and industrial use, to satisfy the current Building Regulations and U-value requirements. The most common applications are below a concrete slab, a screed or particleboard floor finish. The insulation boards are available in a range of grades and sizes to suit project requirements.

EPS is compatible with cement, concrete, brick, masonry, mortars, plaster and bitumen based damp-proof membranes. It must not be used in contact with membranes or other building materials containing solvents. Stylite expanded polystyrene insulation is compatible with all types of screed.

EPS is rot proof and durable, and will remain an effective insulation for the life of the construction. It is not affected by bacteria, moulds or fungi, and will not provide nutrient value for insects or vermin.
