Insulation:- Dukkaboard:- Thermonet strongly recommend the use of tile backer board for insulation and stability purposes, simply screw onto timber surfaces using the washers or adhere to screed or concrete using tile adhesive. Provides a totally water resistant thermal insulation.
- Size: 1300 x 600 x 12 mm. Covers 7.8 m².
- Econoboard:- Improves the efficiency of any underfloor heating installation on a concrete or screed substrate. Thermonet rigid insulation will improve insulation where height build up poses a problem. In both cases the substrate should be firm and stable enough to tile onto as these boards offer no extra structural benefit. Adhere to substrate with tile adhesive.
- Thickness: 10.5 mm. Covers 7.8 m².
- Rigid insulation board:- Thickness: 5 mm. Covers 5.0 m².
- Where height build up is a problem, provides a level of insulation.
Thermostats:- 5260, Standard thermostat kit, max load 16 amps, one per zone.
- 5263, Multizone thermostat, used in conjunction with the standard thermostat kit.
- 5265, 7 day programmable thermostat kit.
- Smart home controller, touch screen intelligent control for many appliances and services. Various finishes available, consult with Thermonet for more details.
