STEICO floors with downlighters

Successful tests with various downlighter manufacturers have been carried out

Due to recent changes in the National House Building Council (NHBC) technical guidance documents various tests have been undertaken to ensure that where downlighters are used in intermediate floors, they still fully comply.

The relevant NHBC guidance document can be found here.

STEICO can confirm that the following downlighter manufacturers have approved test results with the STEICOjoist:

Please contact the relevant downlighter manufacturer for the appropriate certification documents.

STEICO are working closely with other manufacturers and will advise when further approvals are available.

STEICO are also working with the Engineered Wood product group of the Structural Timber Association towards an additional assessment for i-joists, which will provide a robust and cost effective approach for all lighting manufacturers to achieve approval.
