Technical information: isofast IR and plate - treadfast |
|
| Material: |  |
| Screws: | IR hardened carbon steel
Durocoat corrosion protection
IR-S stainless steel, austenitic 316/A4 |
| Stress plate: | steel, aluzinc plated |
|
| Applications: |
| IR | for fastening membranes and insulation to steel deck |
| IR-S | - where the inside atmosphere has a permanently high relative humidity over 70%
- in chemically aggressive atmospheres or conditions
- for refurbishment when the condition of the remaining roof build-up is not known in detail or when the old roof covering damages the corrosion protection and makes it ineffective
- where abnormally long design life is required |
|
Generally:
The supporting thread under the screw head prevents damage to the waterproof
membrane when compressible insulation is used.
The IR screw can be collated for use with the automatic installation tool, IF 240.
Recommended design load:
IR 82 x 40 stress plate - 500N with reinforced membranes and
steel deck 0,7 mm thick (min.) 400 N with homogenous and bituminous membranes.
The design load can vary for each roof system. Please check with the
membrane manufacturers' data.
Installation tools for optimum efficiency:
IF 240
DI 600
