Polystyrene Insulation Sheets

(12 Items)

At Beesley and Fildes, we sell a range of insulation for your home renovation or building needs. 

Polystyrene insulation sheets are made from polystyrene, a synthetic aromatic hydrocarbon polymer made from the monomer styrene. This can be used in a variety of floor applications for both industrial and commercial purposes. 

Our polystyrene insulation sheets are designed to meet the current U-value building requirements. With a range of thicknesses available, such as 2400 x 1200mm x 25mm/50mm/100 & 125mm, you can choose the best application for your project.

These are commonly installed underneath concrete, screens, or chipboards for added insulation. This is ideal for keeping in the warmth during winter and keeping your home cool during the summer, creating a better living environment and reducing your annual energy bills.

Besides floors, polystyrene insulation can also be used for adding an extra layer to walls and ceilings. With easy installation, this is quick to install, perfect for beginners or professional builders. These sheets can be cut to size easily and are commonly installed using adhesives or mechanical fasteners. 

Polystyrene can withstand a certain amount of load without deforming, making it ideal for surfaces which are frequently walked on. Browse our polystyrene insulation sheets below for a home you can rely on.
