Application
Powerlon® UltraBlock AVCLs suitable for all roof and wall applications.
Storage and handling:
- Store the membrane rolls horizontally in a cool, dry, sheltered store.
- Handle the membrane with care and ensure that the membrane is not creased or folded.
Installation:
- Powerlon® UltraBlock membranes should be continuous over the whole plan area of the structure.
- All laps should be sealed with Powerbond® FR Aluminium Tape and the number of joints should be kept to a minimum.
- Cold roofs with Powerlon® UltraBlock membrane draped between purlins, with the insulation above are harder to seal at the laps. In high-risk areas, a rigid lining sheet is recommended throughout to support the Powerlon® UltraBlock.
- Warm roofs where the membrane is supported by the structural deck directly beneath is easier to seal. Sealing tape allows for any slight expansion or contraction movement in the decking.
- Service penetrations should be kept to a minimum. Airtight seals are required around each point of entry including soil pipes, vent pipes, roof lights as well as the roof perimeter.
- Powerlon® UltraBlock should be laid loose, flat and without wrinkles, ensure that the membrane is not creased or folded.
- Cold makes Powerlon® UltraBlock less supple. Installations should be avoided when temperatures fall below 5℃. Installation in windy conditions is not recommended as Powerlon® UltraBlock will become difficult to handle and liable to flap in the wind.
- Timber frame fixings should not puncture the barrier.
- Joins should only be made where the membrane is supported.
- A continuous double row of Powerbond® Butyl Tape spaced 75 mm apart is recommended for overlap sealing. The overlap should be sealed using Powerbond® FR Aluminium Tape. For optimal water resistance and airtightness, using both methods is recommended.
- All joins should be firmly pressed together using a hand-held pressure roller. Only apply tapes in temperatures over 5℃.
- Prior to covering, Powerlon® UltraBlock should be thoroughly inspected to verify the integrity of the joining and sealing to ensure that no damage has occurred. Any damage should be repaired to ensure an airtight seal.
- Damaged areas should be repaired using Powerlon® UltraBlock. The patch must not extend beyond 150 mm of the damaged area. Fix the patch using a continuous double row of Powerbond® Butyl Tape, spaced 75 mm apart.
- Protect Powerlon® UltraBlock from UV exposure. Cover and finish the construction of the VCL installation within a maximum of 3 months.
Overlaps:
- Horizontal overlaps should be 150 mm minimum.
- Vertical overlaps should be 150 mm minimum.

Description
Powerlon® UltraBlock is a range of thermo-reflective air and vapour control layers (AVCLs) incorporating encapsulated aluminium foil to maximize energy efficiency. The reflective foil surface improves the insulation characteristics of the installation, reflecting heat back into the building.
Air & vapour control layers (AVCLs) ensure that the building envelope is properly sealed to control ventilation and prevent heat loss in compliance with Building Regulations Part L. Installed on the warm side of insulation AVCLs prevent moisture within the building's warm air from reaching the insulation therefore protecting insulates from interstitial condensation.
Powerlon® UltraBlock membranes contribute to both BS 9250 for the airtightness in ‘a well-sealed ceiling’ and BS 5250 aiding the control of condensation within a roof space.
Features and benefits:
- Suitable for roof and wall installations.
- Reinforcement scrim.
- Air barrier for controlling ventilation.
- Reflective foil layer for enhanced retention of thermal energy.
- Exceptional water vapour resistance.
- Powerlon® UltraBlock 300 - suited to high-humidity builds >25,000 MNs/g.
- Powerlon® UltraBlock 200 - for general builds > 630 MNs/g.
- UltraBlock SA - Self-adhesive version available.
- CE approval.
