EPS Insulation Fire Testing (when using the FRA addtitive)

In April 2018, tests to the EN 13823 and EN 11925-2 standards were carried out by material testing experts Exova Warringtonfire, to determine the classification of our Expanded Polystyrene Insulation (FRA).

(This covers both our sheet insulation and loose-fill cavity wall insulation.)

Samples of different depths of expanded polystyrene containing flame retardant additive were tested, achieving the following result: Euroclass C-s1-d0* (on depths of 20mm-200mm)

Polystyrene Insulation Guidance

Care must be taken when installing PVC cables, to ensure that they do not come into contact with polystyrene insulation.

A chemical reaction takes place between the PVC sheath and the polystyrene, resulting in a migration of polymers with the cable, known as 'marring'.

• Break your EPS into big chunks and place in the bottom of window boxes, pots, tubs or hanging baskets, under the compost. It helps with drainage, so plants don't become waterlogged. It also reduces the risk of roots freezing in winter - EPS is a great insulator!
• Break into tiny pieces and incorporate into garden compost. Soil will be more aerated, you'll use less compost and the soil will be lighter with better drainage.
• Reuse as packaging - EPS is a great shock absorber.
• Junk modelling with the kids!
• Planters for the garden. Our EPS boxes are deep and perfect for carrots, leeks and mushrooms!
