Alreflex 1L1 is a foil bubble insulation that can be used in cavity wall, dry lining and cold bridging applications. It is a very versatile and low cost insulation that can also be seal as a vapour barrier or used as a dpm in detailing work. It is BBA certified for use as a cavity wall insulation and dry lining insulation.Product Benefits:
- Over 100 million m2 installed in the UK.
- Only 3mm thick.
- Can be used as a vapour barrier or DPM.
- Simple installation.
- Zero GWP and ODP.

Alreflex 1L1 can be used in cavity wall construction to achieve a U-value of 0.45W/m2K. This is a low cost solution to provide a reasonable level of insulation where building regulations are not required or are not applicable.Dry Lining
Alreflex 1L1 can be used as a dry lining to lower U-values, reduce air permeability and lower thermal mass in new-build and refurbishment applications. Alrelfex 1L1 can be used within the Green Deal scheme providing a thin, incredibly cost effective insulation for existing dwellings. In a standard 225mm solid brick construction the addition of Alreflex 1L1 dry lining will improve the U-value of the structure by 59%.Detailing Work
Alreflex 1L1 is only 3mm thick and is extremely flexible, this makes it the ideal solution for preventing cold bridging in difficult detailing areas and in reduced cavity widths. It is regularly used around steel columns, windows and doors, slab edges and wind posts in this type of application.
Alreflex 1L1 is a versatile insulation that has been used by some of the largest house builders in the UK for the past 25 years in various applications. Initially used as cavity wall insulation, it is now predominantly used as a dry lining providing the dual function of enhancing the U-value and reducing air permeability. As a completely flexible and waterproof product Alreflex 1L1 is also used in difficult detailing work and curved structures, where it is not possible to use rigid conventional insulations.
Alreflex 1L1 has excellent environmental credentials. It has a Global Warming Potential of zero and an Ozone Depletion Potential of Zero. No CFCs, HFCs or HCFCs are used in the production of Alreflex 1L1.
