Roofshield® protects
the heritage of Northern
Ireland Church
The world-renowned Roofshield membrane from the A. Proctor Group is now an integral
part of protecting the heritage of St Andrew’s Presbyterian Church, Bangor, and enabling it
to continue serving the local community.
The current church building opened in 1957, and as part
of a £10,000 Cornerstone grant, the redevelopment works
at St Andrew’s will include replacement of the roof,
repairs to the heating system, and a building extension.
air changes to that of a roof using traditional eaves/ridge
ventilation.
A unique performance characteristic of Roofshield is
its patented SMS (Spunbond Meltblown Spunbond) structure, which allows high levels of airflow and the transport
of moisture vapour, making the formation of condensation
in the roof space virtually impossible. Numerous vapour
permeable membranes use an airtight vapour permeable
film layer to achieve their performance. However, the exceptionally high degree of vapour permeability and air permeability of Roofshield means that it can perform in
conditions in which air tight alternatives will not.
Architects Knox and Markwell, specialists in church
design and conservation projects, will lead the project
design. Specialist roofing contractor D. Harkin & Co.
Roofing will carry out the roofing works.
D. Harkin chose Roofshield roofing membrane, which has
long been recognised as one of the highest performing
roofing membrane solutions, providing a pitched roof
underlay, which is both air and vapour permeable.
The products exceptional performance has proven itself in
the most demanding locations around the world. In addition,
its characteristics allow even very complex pitched roofs to
breathe without the need for air gaps or secondary venting.
Incorporating Roofshield into the roofing design can lead
to savings in labour and material costs due to removing
the need for an additional VCL.
The exceptional air permeability performance of
Roofshield means that the roof space will result in similar
