Roofing DuPont™ Tyvek® Reflex
and DuPont™ AirGuard® achieve impressive results for a new timber frame house build in Ireland
Kilbroney Timber Frame are experts in the increasingly popular method of sustainable and efficient construction, with over thirty years of experience in the Irish house building market. For several of their high-spec projects they have chosen to work with DuPont membranes, both for peace of mind and in order to achieve the desired superior results.
Their latest project is an upmarket detached private home in Rostrevor, Ireland built to special commission. A two storey construction with warm- pitched roof and attic rooms, the house offers three bedrooms and a large open plan kitchen living area with a vaulted ceiling.
Built to standards beyond regulation and for optimum energy performance, the project features the very best in building envelope technology. Over an ecologically sourced timber frame, DuPont™ Tyvek® installed to the external walls with DuPont™ AirGuard®
Reflex has been Reflective AVCL
to the interior walls. In between is fitted 140mm insulation board and a service batten. Finally, the walls are finished internally with plasterboard and externally they are rendered. The roof covering is slate and the windows are Alu clad and double glazed.
The house performs as impressively as it looks, with pressure tests for airtightness from the use of the DuPont membrane system coming in as 0.94m3/(h.m2)@50Pa, with U values of 0.12wm2 external walls, 0.12wm2 ceiling.

Mark Cooper of Kilbroney Timber Frame says, “the DuPont membranes were selected following a lot of research to ensure this project would perform as designed, and these were clearly the best materials from what we know to be a trusted brand. The membranes were extremely easy to work with and to install and the results have been outstanding, we will definitely continue to work with these products.”
DuPont™ AirGuard® Reflective is a materialised air and vapour control
layer which is 100% airtight and protects against vapour transmission from the interior into the building envelope. Combining high reflectivity and very low emissivity DuPont™ AirGuard® performance. DuPont™ AirGuard® in the DuPont™ Tyvek®
also enhances thermal works together with other membranes family and special tapes and sealants to create
an air-tight building envelope. This minimises internal thermal losses and helps to create a more comfortable interior environment, while offering significant energy savings. Although sophisticated in terms of technology, DuPont™ AirGuard®
is lightweight and simple to install and suitable for
either new build or renovation projects. DuPont™ Tyvek®
Reflex is a vapour permeable, windtight and watertight membrane ideal for timber frame and vertical cladding, where its properties allow water vapour to diffuse from the structure while also protecting it from the elements. The lacquered, low-emissivity surface ensures long term performance by preventing the materialised surface from oxidising. This means that the functionality of the material is assured from the initial construction process through many years over the life of the building. DuPont™ Tyvek®
membranes offer proven durability against
both heat and UV stress and ageing. This combination of reliability, service and technical assistance helps to ensure that a building operates as the design intends.
