The Wraptite external air barrier system from A. Proctor Group, selected as part
of the façade upgrade to a sea-facing property in Douglas, Isle of Man, will ensure
energy efficiency and protection from the elements.
The Peveril Buildings, previously home for 20 years to the Lloyds Banking Group,
is situated in the centre of the Isle of Man’s Business District, opposite Douglas
Sea Terminal. The iconic property is one of the first office buildings to be seen by
visitors arriving by ferry.
Based in Ballasalla on the island, Excel Construction Group was appointed to
upgrade the facade and improve the building’s structure, aesthetics, and energy
efficiency.
Andrew Burley, Quantity Surveyor at the Excel Group, explains why Wraptite, the
only self-adhering vapour permeable air barrier certified by the BBA, was selected.
“Wraptite provided the building fabric with excellent protection from the coastal
elements prior to installing the Gebrik panels. We will definitely be using Wraptite
on future projects.”
Wraptite combines the critical properties of vapour permeability and airtightness
in one self-adhering membrane. Incorporating Wraptite saves on both the labour
and material costs associated with achieving the energy efficiency demands in
building.
Wraptite is Class B1-s1,d0, compliant with Part B regulation changes for use in the
external wall systems of buildings over 18m in height, both as a continuous layer
on sheathing board behind fire classified insulation, and for use to tape joints in
insulation behind rainscreen."
