The thermo-efficient qualities of Custompac polystyrene bead make it a versatile wall cavity insulation material.

For the safety of our customers, our standard bead polystyrene cavity wall insulation is manufactured with a Flame Retardant additive and tested to BS 5852: 1982 Part 2.

Our handy cavity wall volume calculator is near the bottom of the page if you need it.

IMPORTANT INSTALLATION GUIDANCE:

Care must be taken when installing PVC cables, to ensure that they do not come into contact with polystyrene installation. A chemical reaction takes place between the PVC sheath and the polystyrene, resulting in a migration of polymers with the cable, known as 'marring'. If this occurs, there is a risk of fire. Custompac Ltd cannot be held responsible for improper installation.

All prices include free P&P to Mainland UK (excluding highlands & islands).

EPS Insulation Fire Testing

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)
