Specifications

The decision on which specification to use is the responsibility of the specifier, although both are referred to in RIBA model specification NBS K41 (raised access flooring). In certain public sector projects there may be a requirement to use BSEN.

Because of its greater simplicity, more rigorous selection criteria and use of independent performance testing, the PSA specification is still widely preferred by specifiers and contractors. Permaflor products are, however, available for either specification.

We would always recommend that one or the other is used, not an amalgam of both which can be confusing and leave the specifier more exposed to liability. Advice on product suitability and the merits of each specification can be obtained from our technical department on 01432 353003
