ISOFOAM TEST RESULTS
Tests to BS 4370 : Parts 1-4 : 1988
*
This is a small scale laboratory test and should be used for comparative purpose. It is NOT to be used to assess the potential fire hazard of a material in use.
****************************
The above physical properties have been obtained on the foam produced from injecting CRF into a test cavity wall with a cavity width of approximately 55mm. The test wall had a brick outer leaf and a block inner leaf.
The foam system was injected through holes drilled in the outer leaf using a Gusmer FF proportioner fitted with a model D gun. The holes were drilled at 3 brick centres horizontally and 5 brick centres vertically using a staggered drilling pattern.
The physical properties obtained when making different items using alternative conditions than those detailed above may vary, and should be determined for the intended application. |
