Using Warmup® Insulation Boards with underfloor
heating can lower your running costs by as much
as 50% while reducing your carbon footprint. In
fact, they can pay for themselves in as little as 2.5
years.*
Warmup® Insulation Board is a water resistant,
insulated tile backer board made of extruded
polystyrene, faced on both sides with a fibreglass
mesh embedded into a thin cement polymer mortar.
The board is designed to withstand a load of 30
tonnes per square metre and is ideal for use with
underfloor heating as it prevents the heat from
penetrating down into the substrate below.
As a wall tile backer board, tiles can be fixed directly
onto the surface without prior preparation and,
being totally waterproof, is suitable for wet areas
such as bathrooms and wet rooms. The boards have
a tile load weight of 62kg/m2, to support heavy tiles.
Accessories
Glass Fibre Tape - The tape helps prevent any movement and is used
to cover the joints. One roll per 25 boards.

*Assumes a system running twice a day for two hours on a concrete subfloor **Source: Warmup tests performed to EN442-2 standards, using 10mm board
• Highly Efficient - Can reduce underfloor heating
heat up times to less than 30 minutes as opposed to
2+ hours without insulation**
• Value - can pay for itself in as little as 2.5 years*,**
• Sole Source of Heat - Allows Warmup to be the sole
source of heat in properties built to current building
regulations (a heat loss calculation is always required)
• Effective - Reduces running costs
• Structural Benefits - High compressive strength and
waterproofing properties
• Satisfaction - Enhances customer satisfaction by
reducing heat-up times
• Cost Savings - Reduces the need for additional heat
source on the whole project
• Improved Tile Adhesion - High grab factor. Does not
delaminate
