Compatible Wood Laminates
Compatible Underlayments
Always ensure that your laminate flooring is suitable for use with radiant heating. due to the nature
of Warmup foil panels, we do not recommend their use under floors exceeding 5/8” (15mm). Most
modern wood laminate floors are compatible with Warmup Foil mats.
Wood flooring with metallic strips as part of their locking systems are NOT compatible as these metallic
strips may damage the Warmup® Foil mats.
Laminates that have their pad already attached to the laminate are not compatible with the Warmup
Foil mats.
R-Value of floor covering:
The type and thickness of floor covering materials used with this product must not exceed a thermal
insulation “R” value of 1.
Example R-values: LAMINATE FLOORING = R 0.675
WOOD FLOORING = R 0.80 maximum.
Any type of underlayment / padding can be used as long as it has a density of 6 pounds per cubic
foot.
Certain underlayment such as 6mm thick cork, or 6mm to 10mm of Expanded Polystyrene (EPS) are
recommended for Warmup Foil heating mats. It is also acceptable to place a vapor barrier, such as a
plastic sheet, under the underlayment.
NOTE: Underlayment papers are not compatible with Warmup Foil mats.
Underlayment is necessary to prevent Warmup Foil from being damaged when the weight of the
floor furniture and people are added. Make sure unavoidable wooden floor movements will not harm
Warmup® Foil . Wooden floors expand and contract with temperature and moisture.
PADDING - Warmup FOIL Heating mats must be installed on top of suitable underlayment and cannot
lay directly on the concrete slab.
