polystyrene insulation

Polystyrene Floor Insulation

Expanded polystyrene floor insulation can be a cheap way of building up floor levels whilst giving some insulation. This form of insulant comes in various densities. The standard more commonly used density being EPS70 Standard Density flooring grade polystyrene. These increase in densities to EPS100 , EPS150 , EPS200 and EPS250. A few of the benefits of this type of insulation board is that it is 100% recyclable. Importantly it is biologically inert and non-toxic along with the fact it is flood proof and lightweight so easy to handle.

Although polystyrene is not as thermally efficient compared to say something like celotex insulation materials it can be an excellent way of insulating deep voids cost effectively.
Standard EPS70 has a thermal conductivity of 0.038W/m K. The numbers after ‘EPS’ are relative to the compressive strength in KPa @ 10% compression. These products because of their fragile nature are only sold in pack quantities. This is to lessen the chance of damages.

Very happy with the service we received. Fantastic product at a fantastic price. Cant recommend Jason and the team highly enough. Ordered during Covid-19 when everything was slightly crazy and delayed and Jason called and said they had a lorry in our area so could deliver the very next day! Thank you guys for 5 star service, will be back in the future . All the best, Lacey. Travellers Finds Ltd
