Timber Joist Floor and Ceiling Systems

If you want your floor or ceiling construction to meet and even exceed the prescribed acoustic values, as regulated by the Approved document E of the Building regulations, then you will need a proper upgrade which will additionally improve the fire performance of roof linings and separating and internal floors.

The system includes innovative metal products which are much lighter than traditional timber and blockwork however strong and durable enough; board products which differ in order of fulfilling different requirements in regard to the thermal, acoustic and fire performance of the construction; finishing and fixing products, including screws, sealants and jointing materials and finally effective insulation products designed for acoustic and thermal performance and fire-stopping.
