Short Description
Fire Performance
When Polyfoam Floorboard is installed in a concrete or timber floor construction it will not contribute to the development stages of a fire.
Compression resistance
All materials are compressed under load. Insulation materials used in floors should be capable of accommodating the applied loads with the minimum of compression. Polyfoam Floorboard Domestic is highly resistant to compression and withstands both occasional and long term static loads. A factor of safety for design loads of 3 (5 for long term static loads) is applied to the compressive strength of the product as outlined in the product data tables.
Moisture resistance
The attached detail drawings outline the correct position of Polyfoam Floorboard Domestic. As can be seen in some constructions, the moisture resistance of the board allows it to be laid exposed to ground water, with negligible impact on performance. The board will not provide a water vapour controlling layer, however, it can be laid in ground water or up against wet concrete. Once in position it will not allow moisture to cross through the completed construction.
Thermal insulation
Polyfoam Floorboard Domestic is a high performance insulant, with aged quoted thermal performance values. Unlike most other insulants, the effect of moisture on performance is negligible. The actual performance in use Polyfoam Floorboard Domestic is outlined in the attached application sections.
Product Data
Polyfoam Floorboard Domestic has a Moisture Absorption by Volume of 0.3% and Continuous Service Temperature Limits of -50°C to +75°C.

Polyfoam Floorboard Domestic: Nominal Density 30kg/m3, Minimum Compressive Strength 165kPa
Handling and Storage

Polyfoam Floorboard Domestic is supplied in polythene packs, labelled with identifying product and manufacturing data. The boards are easy to handle and nonirritant, no special protective clothing is required to install them. Polyfoam products should not be left exposed to prolonged sunlight as this will result in surface degradation. Where outside storage for extended periods is required cover with opaque/light coloured sheeting. Ensure the boards are not stored close to open flame or other ignition source, also avoiding volatile organic compounds and chemicals such as solvents.

What insulation values (W/m2K) can you achieve with Polyfoam Floorboard Domestic?

Calculation of U Values

Unlike walls and roofs the heat loss through the ground floor varies with its size and shape. When calculating floor U-Values a ratio of the exposed floor perimeter to the floor area is required. The measurement of the perimeter and area is to the finished inside surfaces that enclose the heated space (unheated spaces such as garages should be excluded)

To calculate the actual P/A, take the internal measurements of the exposed floor perimeter only and calculate the total floor area.

Insert them into the formula below to find your P/A

P/A = Exposed perimeter of floor ÷ Area of floor
Application
Polyfoam Floorboard Domestic is used for the thermal insulation of floors. In domestic flooring insulation, the optimum solution has to:
  • be good value for money
  • be a good thermal performer
  • be strong
  • be easy to install
  • be lightweight
  • be structurally stable in the long term
  • have low moisture absorption
The following range of applications are some of the key areas of use of Polyfoam Floorboard Domestic:
  • General domestic load flooring
    • Housing
Polyfoam Floorboard Domestic is suitable for almost any floor construction including:
  • Below a concrete slab
  • Below screed on a beam block suspended floor
  • Below screed on an upper/intermediate concrete slab floor
  • Below chipboard on a beam and block floor
  • Below chipboard on a ground bearing concrete slab
