Dupont™ Tyvek® Is Cast As A Reliable Performer In Poldark Country
DuPont™ Tyvek® Supro, which offers unrestricted BS5534 compliance, is the favoured choice of Marnick Roofing Ltd and has been chosen for a development project in Cornwall’s beautiful, windswept Sennen Cove. Photo Bradley Cameron for DuPont™ Tyvek® all rights reserved
The windswept shore line of beautiful Sennen Cove in Cornwall offers both an inspiring outlook – and a particular set of challenges for building to contemporary codes. On a rugged rise overlooking the bay, a developer has completely renovated a 19th Century two-storey stone built cottage, while complementing it with a sympathetic addition to create one large, luxury, four-bedroom house with pool and terrace.
The renewed property is designed to the highest standards and so concerns such as interior climate comfort were as much a consideration as was protecting the structure from the Cornish coastal weather. For the construction of the pitched, slated roofs, contractors Marnick Roofing Ltd of Falmouth chose to rely on the company’s favoured underlay material: the advanced breather membrane DuPont™ Tyvek® Supro Plus.
Long established as a proven performer in terms of water-shedding, moisture management, airtightness and enhanced thermal efficiency, DuPont™ Tyvek® also offers unrestricted compliance with BS5534:2014 for all wind zones and at all altitudes. Considering the exposed location of the property, this wind-uplift resistance together with trouble-free installation, made DuPont™ Tyvek® a wise investment for a development designed to perform for the long term.
Paul Marks of Marnick Roofing Ltd says, “The choice was clear, not only in terms of the quality of the product, but also because we know we can depend on great service from DuPont. This is a high-spec project in a spectacular natural setting and we are proud to have been involved.”
DuPont™ Tyvek® is unique in the market because of its high-quality single layer construction which is naturally vapour open but also wind and water-tight. This is due to its composition of millions of micro fibres bonded together to make a “maze” that’s impermeable to air and moisture but which allows water vapour to pass through its natural pores.
In terms of wind-uplift resistance, all three BBA approved roofing underlays in the group: DuPont™ Tyvek® Supro, DuPont™ Tyvek® Supro Plus (with integral tape) and DuPont™ Tyvek® Enercor roof offer unrestricted application when tested in accordance with BS5534:2014 – and with no counter battens required in any zone. This allows contractors to be confident that they in are full compliance, not only with the code, but with all the weathering and thermal performance expectations of an advanced breather membrane.
Lethame House Aims High with DuPont Building Membrane Solutions
For their luxury housing project at Strathaven near Glasgow (Scotland), Apex Developments Ltd. opted for high-class specifications throughout. That included one key feature that isn’t immediately visible – energy efficiency. To provide both moisture and weather proofing and energy efficiency, Apex chose DuPont thermal performance solutions.
The Challenge
The Lethame House development was designed to offer the best of both worlds by combining traditional, locally sourced materials (timber frames, stone cladding and slate roofing) with state-of-the-art energy efficiency. The developers specified a thermal solution that would not just meet, but exceed thermal efficiency and airtightness regulations.
“We chose these membranes because they are renowned as a reliable, durable brand”, said Jim Simpson, Managing Director of Apex Developments. “We have worked with DuPont™ Tyvek® before, and have every faith in the material. We wouldn’t want to gamble on something that might be substandard on a project with such high aims. We want to be confident in handing over the keys to a quality home that will bring enjoyment and value for many generations.”
The Solution
Lethame House combines an array of advanced systems and technologies for all-round energy efficiency. These include geothermal heating systems with 200-metre boreholes, and a modern heat recovery system that keeps energy wastage to a minimum.
Another key component is the high quality DuPont thermal solution, which protects the structure while keeping occupants cooler in summer, and warmer in winter.
Key Advantages
The combination of three lightweight, top quality DuPont building membranes provides all-round protection and thermal efficiency – improving interior comfort while also reducing the carbon footprint.
Internal walls were clad with AirGuard® Reflective, a low-emissivity membrane that is impermeable to air and moisture. During the winter, AirGuard® Reflective plays a key role in preventing heat loss by reflecting up to 95% of internal radiant heat.
For external walls and roofing, two building membranes made of proven Tyvek® were chosen. Tyvek® breather membranes have a unique single-layer construction and are naturally vapour open, yet wind and watertight.
External walls were covered with Tyvek® Reflex, a metallised, low-emissivity membrane. For the roof, Tyvek® Supro breather building membrane was specified.
