Technical information: isofast IP |
|
| Material: |  |
| Screw: | Fibreglass reinforced (Zytel ®) |
| Stress plates: | Aluzinc coated steel |
|
Application:
For fastening membranes and insulation to woodwool structural roof decks (to BS 1105) of minimum thickness 50 mm.
Generally:
Minimum embedment of 38 mm into the woodwool must be achieved. Maximum pull out values are achieved by full thread engagement, i.e. 58 mm.
Unwinding under dynamic wind loads is prevented by the unique ratchet system and barbed stress plates.
Pre-screeded woodwool requires a clearance hole of 18 mm be made into the screed only.
Installation must be made with slow speed (max. 700 rpm).
Normally, the isofast IP screw can be installed into woodwool without pre-drilling.
On some refurbishment contrcts pre-drilling of the existing build-up may be required.
Pull-out tests must always be made on all projects to confirm performance and suitability - contact SFS.
Recommended design load to be maximum 400 N and is dependent on on-site pull-out tests.
Installation tools for optimum performance:
DI 600 (speed control by trigger) electric screwdriver
