High performance insulation and rain barrier

Alreflex Platinum

An all encompassing cavity wall solution to Part L 2006 and Part 6 Scottish Standards

  • A 50mm thickness of Alreflex Platinum ® can achieve a U-Value better than 0.35W/m2K in a 100mm cavity using any 100mm standard medium density block.
  • This detail will still meet the requirements of the new Part L 2006 based on current information.
  • Available in a range of thicknesses to meet the various building regulations requirements. (See U-Value solutions on back page.)
  • BBA Certificated Platinum board laminated to BBA Certificated Alreflex 1L-1 Super R Class O of which approximately 4 million sq.m. has been successfully installed in UK housing.
  • Special overlapping joints secured by wall tie clips creating a waterproof rain barrier to prevent ingress of water across the cavity.
  • Continuous overlapping system to aid air tightness of wall.
  • 1200 x 450 boards installed as standard cavity wall boards but with laps secured on wall ties.

Installation Procedure

Walls are constructed in the conventional manner with special Alreflex ® wall ties spaced at 450mm vertically and 900mm horizontally. Alreflex Platinum ® is installed on top of a run of wall ties in the normal way with the lap slit with a knife at the wall-ties to allow the flap to run past the wall-tie and lie flat on the board.

Secure the board with the clips in the normal way. The special downstand on the Alreflex ® wall ties takes up any possible vertical pressure experienced when installing the boards and clips.

Alreflex Platinum ® Cavity Board

Cavity wall insulation and rain barrier. Laps provide a continuous water proof barrier against the ingress of rainwater etc.

25mm Board achieves: U = 0.35W/m2K with 100mm (K=0.11) aerated block

  • Achieves Part L 2006 requirements with a minimum 75mm cavity in most house types.

50mm Board achieves: U = 0.35W/m2K with 100mm concrete block

U = 0.30W/m2K with 100mm (K=0.19) aerated block

  • Can achieve Part L 2006 requirements with a minimum 100mm cavity in most house types.
  • Extensions in England & Wales; U Value of 0.30 is the elemental value for walls in extensions based on Part L 2006

*These details are especially suitable for high rise and commercial buildings.

U = 0.27W/m2K with 100mm (k=0.11) aerated block

  • Extensions in Scotland; U Value of 0.27 is the elemental value for walls in extensions based on Part 6 Scottish Standards

50mm THICK ALREFLEX PLATINUM ® CAVITY BOARD WITH ALREFLEX 1L1 DRY LINING OR THERMAL LAMINATE BOARD

Cavity wall insulation and rain barrier with high performance dry lining and vapour barrier. Laps provide a continuous water proof barrier against the ingress of rain water etc. U = 0.25W/m2K with 100mm (K=0.19) aerated block.

  • Suitable for all areas and projects where a low U-value is required (i.e. in electrically heated flats etc.)
  • High comfort level with quick "heat-up" period.
  • Also suitable for 3-storey housing and flat construction.
  • Ideal for all exposure areas.

Please note: If a laminated board with a dot and dab fixing is preferred to the 1L1 DRY LINING detail shown, please contact our technical department for suitable boards and thicknesses.
