Polyfoam Raftersqueeze
Product Description
For thermal insulation between rafters in hybrid warm roofs
Description
Polyfoam Raftersqueeze is a high performance, 100% ozone friendly, extruded polystyrene, rigid board insulation. It is lightweight and consists of a flexible infill piece of insulation to fit between rafters, even allowing for some timber variation. Polyfoam Raftersqueeze is supplied straight edged with grooved sections designed to compress to simplify installation.
Application
Polyfoam Raftersqueeze is used for thermal insulation of pitched roofs between rafters in new build or refurbishment. A common problem in pitched roofing is variation in timber and the difficulty in accommodating this with a rigid insulation. Polyfoam Raftersqueeze is:
- thermally efficient
- stable in the long term
- rigid
- lightweight
- easy to install
- compressible to make installation simple
- practical, allowing for some measuring tolerance
- self-retaining in position before permanent fix is carried out
The following range of applications are some of the key areas of use of Polyfoam Raftersqueeze:
In warm pitched roofs in new build and refurbishment in:
- Housing
- Schools
- Hospitals
- Offices
Polyfoam Raftersqueeze is suitable for almost any warm pitched roof construction including:
- In new build between rafters at 600 centres (See Sarking Board System)
- In new build and refurbishment of roofs between rafters where the roof is replaced (See Pitched Roofboard)
- In refurbishment change of use to a room in the roof.
Performance
Compression resistance
The rigidity of Polyfoam Raftersqueeze makes the board easy to handle and less prone to site damage than less robust materials.
Moisture resistance
Polyfoam Raftersqueeze is highly resistant to moisture absorption and will perform as stated if exposed to condensation or other moisture in use.
Thermal insulation
Polyfoam Raftersqueeze is a high performance insulant, with aged quoted thermal performance values. The actual performance in use of each grade of Polyfoam Raftersqueeze is outlined in the attached application section.
Fire Performance
When Polyfoam Raftersqueeze is installed in a roof construction it will not contribute to the development stages of a fire.
Handling and storage
Polyfoam Raftersqueeze is supplied in polythene packs, labelled with identifying product and manufacturing data. The boards are easy to handle and non-irritant, 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 compounds and chemicals such as solvents.
