InSkew Enquiry Form

The InSkew 600 is used as a structural batten fixing, normally being fixed through the counter-batten, the insulation sarking and then a minimum of 35mm into the rafters.  The density of fixing (the number of fixings per Mē ) must be enough to resist both the wind suction & the sliding load.

Occasionally the InSkew 600 is fixed through the tile-batten as well as the counter-batten; in this case please phone the Helifix sales office for advice.
