The Warmup Underlay / Dual Overlay systems are designed to work specifically with Warmup Foil Heaters only.

How is Dual Overlay sold?


Each pack contains: 4 base boards & 4 top boards and covers 2.88m² of flooring.

Why do you recommend Insulation Boards on a concrete base?


The insulation boards are used to prevent heat escaping downwards to the subfloor, improving the efficiency of the system. Insulation boards can reduce running costs by as much as 50% because they are a highly efficient thermal barrier to cold rising from the subfloor. By reflecting the heat upwards instead of losing heat to the […]

What does R Value mean ?


The R value is a measure of thermal resistance used in the construction industry. The higher the R value the better an insulator (e.g. 10mm Warmup® Insulation Boards have an R value of 0.28 m²K/W and the 20mm Warmup® Insulation Boards have an R value of 0.58 m²K/W). All buildings should strive for the highest […]

What are Warmup Insulation Board made from?


Warmup® Insulation Boards are made of waterproof extruded polystyrene with a glassfibre mesh embedded on each face, onto a cement polymer adhesive. The boards are fully waterproof, preventing any water to pass through them in the way expanded polystyrene boards do. They are lightweight, easy to cut with a knife and install onto any surface. […]

Where can I use Insulation Boards?


The Warmup insulation boards can be used on Floors & Walls Warmup® Insulation Boards can be used as a structural tile backer board on the floor, withstanding a load of 30 tonnes/sqm and are ideal for use with underfloor heating. They offer the added benefit of high sound proofing properties. We recommend a minimum thickness […]

Can I use the Warmup Loose Wire System as a primary heat source?


If your room is well insulated and complies with modern insulation levels you should be able to use Warmup as the sole heat source. However, if your house is an older property with lower insulation properties it is likely that an additional heat source may be required. Heat loss calculations can be carried out by […]

Can the DCM-PRO system reduce the risk of my tiled floor developing cracks?


As a decoupling system, the DCM-PRO’s anti-fracture membrane has been designed to absorb the normal lateral movement which occurs when the subfloor and finished floor expand and contract at different rates; a common cause of cracked floor tiles. This has been backed up with a High Performance rating for crack isolation, as externally tested according […]

Can I install my Warmup system directly on top of plywood?


This page outlines installation recommendations when installing over a plywood sub-floor.

Warmup Insulation Boards: Preparing for the Installation of Floor Heating


All surfaces should be thoroughly cleaned of all dirt and debris. When installing over an existing concrete base, it is important to remove all traces of existing finishes, contamination, etc. to allow for a clean surface.
