Proctor Roofshield roof applications from Dynamic Composite Technologies
Proctor Roofshield was developed in Europe to address the breather
membrane needs of building envelope construction. Roofshield is a 3-ply spun bonded
polypropylene fabric that is used as a breathing underlayment for roof systems. It
is U.V. stabilised, rot proof and tear resistant.
Prevention of water migration into the building is the primary function of the roof
construction and external cladding. A roof underlay acts as a secondary drainage layer
under the roofing material to provide added protection from the ingress of water into
the roof space. The Roofshield breathable roof underlay offers the added benefit of
enabling the roof cavity to naturally release vapour before condensation forms within
the roof space of building envelope.
Long Term Condensation Control
The concept of a weather resistant barrier may not be new in the construction industry.
A product that is able to keep moisture out while still allowing your building to breathe
is unique.
Unlike foil products, Roofshield due to high vapour permeability lets the building breath.
In temperate climates this permits vapour to escape without reaching dew point thus
preventing condensation and related problems such as mould, swelling, distortion &
rotting of timber, corrosion, and loss off thermal insulation performance.
Reduces Risk of Mould and Mildew
The subject of mould and mildew is of great importance and concern in the construction
industry today. The concept of "sick buildings" is a term that all designers and building
owners are aware of and are trying to prevent. Products which do not allow your building
to breathe adequately may actually be trapping moisture, which is the primary cause of mould.
