Isolecta Insulation Board – energy saving insulation board.
Isolecta Insulation Board
The Isolecta insulation board is a lightweight insulated tile backing board, with double-sided glass-fibre-reinforced cement layer. It provides an excellent sub-floor for use with:
- Raychem T2 QuickNet heating mat.
- T2 Blue 10W/m .
- CeraPro heating cables.
Supplied in a pack of 4 plates (2.85m2) – 1800 x 600 x 10mm.
Available accessories
Self-adhesive tape, 25m x 125mm for covering the joints.
Galvanized fixing nails (35 pcs/box).
Galvanized washer + screws (35 pcs/box).
20 Plastic cable spacer. Length: 400mm, grid: 25mm, 20pc/bag.
100 Plastic cable spacer. Length: 400mm, grid: 25mm: 100 pc/bag.
Benefits
- Energy savings of approximately 20%.
- Vapour barrier provides an excellent resistance to moisture.
- High level of thermal insulation.
- Ideal subsurface for thin bed tiling and underfloor heating systems.
- Compatible with most proprietary tile adhesives and filler material.
Applications
- Living rooms.
- Bathrooms.
- Kitchens.
- Dining rooms.
- Children’s rooms.
- Conservatories.
- Home offices.
Floor coverings
Sub-floor
- Concrete.
- Cement screed.
- Anhydrite screed.
- Wooden sub-floor.
- Timber floor board.
Energy savings and a fast heat-up
- The heat-up time for T2QuickNet, T2Blue, and CeraPro is three times faster in combination with Isolecta insulation board. This results in energy savings of up to 65% during the heat-up phase.
- Approximately 20% of extra energy savings during operation due to reduced downward heat loss.
- The ideal substrate for tiling due to the double sided cement layer with integrated glass fiber mesh.
