Top hats for sealing to a gas barrier and at the intersection of pipe projections, available in sizes from 55mm to 160mm. Compliant with Building Regulation Approved Documents C1 and C2.
Common applications are for soil and service pipes passing vertically via a gas barrier or membrane to maintain a continuous seal. Top hats are suitable for installation at ceiling level for pipe protrusions to assist in reducing air leakage. All jubilee clips are supplied separate to top hat units.
Flexible top hats for sealing to a gas barrier and at the intersection of pipe projections. Designed to be flexible enough to fit around difficult applications and are ideal for use in tight situations where a pipe is close to a wall. Compliant with Building Regulation Approved Documents C1 and C2.
Uses:
In areas outlined in BRE document ‘Radon’ guidance on protective measures in new dwellings
When gas protection is required across the footprint of the building
Crossing cavity wall constructions to maintain gas barrier integrity
Forming internal perimeter trays to allow membranes continuity
Collars for service pipe protrusions
Following a risk assessment where the requirement is for a good gas protection measure against Radon, Co2, Methane and Hydrocarbon
To be designed and installed in a continuous system around the whole building perimeter
Installation advice Units will require tape and seal - tape sold separately. Use Gtape01 to make the seal between joint surfaces. Use Gtape02 to seal upper surface to minimise lap lifting if used in concrete floors
