Standard Joists

Standard Joists

25mm x 25mm battens should be fixed along the length of the joists with 9mm to 18mm plywood laid over the battens so the surface of the plywood is 70mm below the surface of the joists. 40mm insulation is laid over the plywood between joists and pipe is fitted to the insulation. Where necessary, the joists are notched to allow the pipe to pass from one bay to another. The pipe is connected to the manifold, relevant tests are carried out to ensure system integrity and the floor covering is laid over the top. The pipes should be encased in an 8:1 blend of sand and cement which should be made level with the tops of the joists.

Engineered Joists

Engineered Joists

Engineered joists may not be notched to allow the pipe to pass from one bay to another so a different method must be used. A wooden decking consisting of 18mm plywood or 22mm chipboard must be laid over the joists. Once the decking is in position, the underfloor heating system can be installed using any of the within screed, floating floors, or battened floor systems described above.
