Glidevale abutment
ventilation systems have been designed to provide a range of
solutions to provide high level ventilation into the roofspace in an
unobtrusive way.
MR50Monovent
The MR50 Monovent
provides unobtrusive ventilation to top edge abutments of lean-to
roofs. The innovative design ensures a continuous ventilation gap of
5000mm²/m. MR50 Monovent is recommended to be used in conjunction
with Glidevale eaves ventilation systems to ensure through
ventilation of the roofspace from low to high level. When used with
Type LR underlay such as Protect VP400 PLUS LR it can also be used on
its own to provide the ventilation requirement.
Benefits MR50 Monovent:
- Guaranteed
5000mm²/m ventilation provision to comply with BS 5250 and Building
Regulations.
- Deluge and driving
rain resistant as well as preventing large insect ingress.
- Suitable for
installation under dormer window sills when insulation is at rafter
level.
- Unobtrusive when
installed. Hidden within the roof flashings.
- Available with
integral AluFlash, the environmentally friendly lead free
alternative.
- Each unit overlaps
the next to ensure integrity of flashing.
- Quick and easy to
install.
AV50 AbVent
The Glidevale AV50
AbVent provides unobtrusive high-level ventilation and can be used in
conjunction with traditional ‘lead roll’ details on plain tile
and slate roofs. It is also particularly useful in top edge abutment
situations where MR50 Monovent cannot be installed because of limited
vertical clearance.
Benefits AV50 AbVent:
- Guaranteed
5000mm²/m ventilation provision to comply with BS 5250 and Building
Regulations.
- Deluge and driving
rain resistant as well as preventing large insect ingress.
- Unobtrusive when
installed. Hidden within the roof flashings.
- Available with
integral AluFlash, the environmentally friendly lead free
alternative.
- Each unit overlaps
the next to ensure integrity of flashing.
- Quick and easy to
install. Does not affect the normal laying of the roof covering.
- Minimum pitch 20º.
