Underfloor Direct Ltd


Floor Types

Underfloor Heating has been firmly established in mainland Europe for many decades and is installed in virtually every family home.

Originally used to take the chill off cold floors in single rooms, e.g. bathrooms and hallways with stone tiles, Underfloor heating has been developed to become a standard, complete in-house heating system, irrespective of floor materials and coverings.

Due to the variety of floor constructions and material coverings available, Underfloor Direct has provided some information on the best construction methods and floor coverings to get the most warmth and comfort from an Underfloor system.

Floor Coverings

Underfloor Direct heating systems are suitable for most floor finishes, including natural stone and ceramic tiles, timber flooring and carpet. See summary table above:

Ceramic Floor Tiles (including flagstone, slate etc.)

Underfloor heating works very well with ceramic and stone based floor-coverings which are excellent conductors of heat. Their aesthetic appeal is enhanced by their warm feel.

Plastic or Vinyl Floors

Plastic floorings represent little resistance to heat transfer and most are suited to underfloor heating applications. The floor-covering and the adhesive used with the covering should be suitable for temperatures of 40°C and show no softening or loss of adhesion at these temperatures.

Carpets

Most carpets are suitable for underfloor but thick underlays will restrict the heat transfer, this should be considered at the design stage. Thermal resistance should not less than 0.15m2 K/W (TOG 1.5) Insulated carpet with underfelt is one carpet which should not be used.

If carpets are to be stuck down, the adhesive used must be suitable for temperatures of up to 40°C.

Timber Floors

The increased popularity of timber floors has ensured that most strip boards and modern laminates are compatible with underfloor systems.

Important: Check with the manufacturer before installation that your floor
surface is suitable for underfloor heating.
