Alreflex Full Fill is a cavity wall insulation that is BBA certified for use with only a 10mm residual cavity, this means that it is classed as a full fill insulation. This allows lower U-values to be achieved or construction depths to be reduced and saleable floor area increased.

Product Benefits:
  • BBA certified insulation and cavity rainwater barrier
  • Reduces construction depth giving increased saleable floor area
  • Simple installation
  • Zero ODP and GWP<5

Board Sizes:
450mm x 1200mm

Board Thickness: available in 5mm increments from 40mm

K-value of Board: 0.030W/mK

R-value of Alreflex Foil and cavity to face: 0.38m2K/W*

Density: 13 – 15 Kg/m3

*value shown is for non-ventilated cavity of 10mm

Cavity Boards

Alreflex Full Fill cavity boards are designed for use in masonry structures. These boards have a square edge and a bubble foil outer face. All joints are sealed with Alreflex Breathable Tape and this creates a BBA certified cavity rain barrier. The exceptional performance of this cavity rain barrier means that Alreflex Full Fill is certified to be used with a reduced cavity of just 10mm.

Alreflex Full Fill is a graphite enhanced EPS insulation board with Alreflex bubble foil insulation bonded to the outer surface. The combination of high performance EPS and Alreflex foil provides an extremely cost effective alternative to PUR/PIR boards. These boards have been specifically developed for use with a reduced residual cavity of just 10mm, this means that more insulation can be used in the cavity to provide improved U-values or the overall construction depth of the wall can be reduced.

Available in 5mm thickness increments starting at 40mm, Alreflex Full Fill can be used to meet most U-value requirements. From standard regulation compliance and general improvement to achieving extremely low U-values for Home Quality Mark, Code for Sustainable Homes or FEEs compliance. Alreflex Full Fill provides a cost effective solution and is significantly cheaper than the equivalent PUR, PIR and Phenolic board insulations providing the same thermal performance.

With a BRE Green Guide A+ rating Alreflex Full Fill has excellent environmental credentials. It has a Global Warming Potential of less than 5 and an Ozone Depletion Potential of Zero. No CFCs, HFCs or HCFCs are used in the production of Alreflex Full Fill.
