Biscuit Screed
Underfloor Heating
System
The Biscuit mix system is, in theory, a screed staple system. It uses insulation, pipe and staples but installed between joists either within a suspended floor or floating. With reduced screed height of 25mm and comprises an 8:1 sand cement dry mix.
We can provide staples in 40mm, 50mm & 60mm. Our staples are universally used by many underfloor heating suppliers and therefore fit into most staple guns.

Wood Flooring
Wood and laminate flooring can be laid directly on to the screed systems, along with an underfloor heating suitable underlay. You should always consult the flooring manufacturer to ensure the wood floor is suitable with underfloor heating. The wood floor should not exceed 27°C
Tile Flooring
Tiles can be laid directly on to screed using a flexible tile adhesive. We strongly advise the use of a decoupling membrane, this will help prevent cracks and also provide a separation layer should you want to change the tiles in the future.
LVT/Vinyl Flooring
LVT / Vinyl need to have a flat surface to lay on. It is recommended to speak directly with the manufacturer to ascertain any pre-existing requirements prior to installing LVT or Vinyl. The vinyl floor should not exceed 27°C.
Carpet Flooring
Carpet floors require a flat surface to lay to and a underfloor heating suitable underlay should be used to avoid restricting the heat from passing through into the the space above
