Fire-protection boards and
mineral roof layers

The right layer for your roof: SHEET beneath new waterproofing, VLOEI as a site-applied mineral roof coating and WEER as boards above the membrane beneath PV.

Roof build-up

Where each layer sits, and what it does there.

Select a layer below or above the waterproofing in the section. Below the membrane, the mineral layer is sheltered from direct weather exposure. Above it, rain, frost, wind and contact with the existing membrane also matter.

Schematic positions, not an installation drawing. WEER and VLOEI show alternative material routes above the membrane; SHEET sits below it. The illustrated layers are not automatically combined.

VlamShield PV mounting system

PV mounting system · With WEER boards

VlamShield PV mounting system

One board performs several jobs: weather-resistant WEER forms the mineral fire-protection and roof-protection layer beneath the modules. Directly connecting it to the supports also makes its own weight available as ballast. The connected boards support load spreading across the roof build-up.
