RE: Hot knife for HA conduit ...

["Neil Ball" <neilball@xxxxxxxxxxxxxxx>]

Have you considered other approaches? Polarwall (A ICF supplier)
suggest
using a router to cut the channels, messy but does not require any
specialist kit. Polystyrene also reacts with the plasticisers in the cable
insulation making brittle with over time so all cabling need to be within
suitable conduit.

'wondered if someone could recommend a good hot knife for cleanly
cutting channels for conduit in polystyrene foam ... for the HA, we
need to run lots of Cat-5 & power cables, and need a quick way of
doing it before we plaster (most of our walls currently being
polystyrene on the surface) ... 'thought it would be easy, but
finding a suitable hot-wire / hot knife is proving impossible !
