To comply with Building Regulations Part E, we can offer T-shaped blocks, for use with our 155mm deep T beam, that will satisfy the majority of requirements, but will need pre-completion testing.
Stowell T beam blocks can be used at 374mm or 289mm centres.
Stowell T beam blocks have a nominal oven-dry density of 1900kg/m3 and are transverse tested.
Careful consideration of their use should be made at the design stage as there is less flexibility in their use e.g. can only use double joists, not triples where beams interlink.
At 374mm centres the mass of 1m2 of floor = approximately 320kg.
At 289mm centres the mass of 1m2 of floor = approximately 325kg.
Although the system provides a flush soffit it
is not recommended
that a plaster finish is applied directly to them.
