| IR / IR-S: | |
- for fastening membranes and insulation to steel deck
- 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

Generally
The supporting thread under the screw head prevents damage to the waterproof membrane when compressible insulation is used. The IR screw is collated for use with the automatic installation tool, IF 160/240.
Recommended design load:
IR 82 x 40 stress plate - 500 N with reinforced membranes and steel deck 0,7 mm thick (min.) 400 N with homogenous and bituminous membranes.
Installation tools for optimum efficiency: IF 240 and DI 600
