Lewis Plates


Lewis plates cross-section diagram

Lewis Plates are rolled self-supporting, dovetailed, galvanised steel reinforcement sheets which allow lightweight concrete floors of limited thickness to be laid on (primarily) timber floor framing. The plates are laid over the joists and nailed or screwed down; the underfloor heating pipe is clipped to them and a screed is then laid on top. Ideal for use on top of a joisted structure where they help spread the load-bearing capacity of the floor.

Wall Plates


Wall heating is another great way to heat a building.  It's also a really effective means of delivering cooling. It is particularly suitable in offices or buildings with extensive cabling systems in the floor. It is also particularly viable where, for some reason, the existing floor can't be removed or altered to accommodate underfloor heating or where there is insufficient height. This renders it particularly suitable for retrofitting, though may not be the ideal solution in an art gallery!


Like underfloor heating, wall heating saves space, turns walls into radiators and can link up with micro-renewable technologies. It is similar to floor heating,  except it delivers approximately 25% higher cooling output if this is also required.  It can be installed directly behind plasterboard walls or steel plate.
