AS30 profile sheets are single skin (0.5mm gauge walls & 0.7mm roof). AS35 composite sheets are an insulated,
double skin panel. Both systems have a plastisol-coating to the exterior face. Note: self-build kit does not include
silicone sealant for use on drip flashings, guttering etc. Insulated buildings may also require rockwool insulation to
fill voids at corners, barge & eaves.

( 1 no per bay – approx. 1.5% of wall area)
Single skin AS30 skylights may be prone to condensation in certain conditions.
Anti-condensation Barrier
= Not required
Condensation may form on the underside of single skin steel sheets without a condensation barrier. Not required
on AS35 composite panels and cannot be applied to skylights.
