Polyfoam Raftersqueeze
For thermal insulation of pitched roofs
Description
Polyfoam Raftersqueeze is a high performance, 100% ozone
friendly, extruded polystyrene, rigid insulation board.
Polyfoam Raftersqueeze is supplied straight edged and has a
series of grooves along each long edge. The grooves are designed to
compress during installation to provide a friction fit between
rafters.
Application
Polyfoam Raftersqueeze is used for thermal insulation of pitched
roofs. It is designed to be friction fitted between rafters at
600mm centres, and allows for some timber variation.
Polyfoam Raftersqueeze is often used in combination with
Polyfoam Pitched Roofboard.
Standards
Polyfoam Raftersqueeze is manufactured in accordance with BSI
Quality Assurance Standard BS EN ISO 9001: 2000.
Durability
The continuous service temperature limits of Polyfoam
Raftersqueeze are -50 to +75º C.
Moisture absorption
Polyfoam Raftersqueeze has a moisture absorption of 0.3% by
volume.
Thermal Performance
Polyfoam Raftersqueeze has a thermal conductivity of 0.030
W/mK.
- Friction fit between rafters
- Compressible for easy installation
- Allows for some variation in timber centres
- Excellent thermal performance
- Lightweight and easy to install
Environmental
Polyfoam Raftersqueeze is free from CFCs, HCFCs and any other
material with ozone depletion potential in its manufacture and
content and represents no known threat to the environment. Polyfoam
Raftersqueeze is non bio-degradable.
Polyfoam Raftersqueeze is 100% recyclable.
Compression resistance
The rigidity of Polyfoam Raftersqueeze makes the board easy to
handle and less prone to site damage than less robust
materials.
The grooves along each long edge allow a degree of compression
across the width of the board. This allows it to be friction fitted
between rafters.
Moisture resistance
Polyfoam Raftersqueeze is highly resistant to moisture
absorption and will perform as stated if exposed to condensation or
moisture in use.
Vapour Resistivity
Polyfoam Raftersqueeze has a vapour resistivity of 480
MNs/gm.
Handling and storage
The boards are easy to handle and nonirritant, no special
protective clothing is required when installing them.
Polyfoam Raftersqueeze is supplied in polythene packs, labelled
with identifying product and manufacturing data.
Ensure the boards are not stored close to open flame or other
ignition source, also avoid volatile compounds and chemicals such
as solvents.
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.
