Water Underfloor Heating between Joists
Joist and suspended floor installations are a lesser known type of water underfloor heating system, but an incredibly versatile and effective one. Since they have no increase at all to the floor height they can be incorporated into existing properties as well as new builds with relative ease. Joist systems involve laying the pipes between the joists using one of the three methods shown below. The most popular choice is the aluminium spreader plate, but the aluminium insulation board and dry screed mix both offer equally effective but different suitabilities. This type of heating system works by drawing the heat into a heated element and transferring it quickly into the room above, making the response time very quick when turned on. The joist system is less efficient then the screed system, but many time more effective than radiator heating.
There are 3 different fixing methods for water underfloor heating joist systems to choose from…
Aluminium spreader plates
Aluminium insulation boards
Dry screed mix

We only use high quality European standard Pert-Al-Pert pipe in all our water underfloor heating systems.
Our range of pert-al-pert pipe is manufactured to ISO9001 European standards ensuring a lifetime of outstanding performance & reliability.
Five layer 16mm pert-al-pert pipe is used in all of our warm water underfloor heating kits and offers unrivaled suitability for underfloor heating by combining the best elements of a plastic and metal pipe into one product.
The aluminium core provides strength and importantly acts as an oxygen barrier to stop the ingress of oxygen into the system causing premature wear (corrosion) to the manifold. The aluminium layer also makes the pipe form-stable, making it very easy to work with by eliminating spring back for easier installation.
