When building for airtightness is an education: Tyvek® at the John Taylor Free School

November 2018

When building for airtightness is an education: Tyvek® at the John Taylor Free School:

Building for education presents both challenges and opportunities in today’s public sector construction. While budgets must be carefully controlled, it’s also essential to achieve the highest specifications in order to ensure a lasting and cost-effective investment. The best in modern building technology is vital to delivering a project that performs as designed and meets all key criteria, particularly in terms of sustainability and reduced maintenance.

The John Taylor free high school in Burton-on-Trent is a complete new-build development on a greenfield site, commissioned to meet the growing needs of the Staffordshire education system. The £25m PPP funded complex by Glancy Nicholls Architects includes a state-of-the-art sports hall and caters for 1,400 secondary and sixth form pupils.
When Perkins Plasterers were contracted by Seddon Construction Ltd to ensure the integrity of the building envelope, with particular regard to airtightness, it soon became apparent that a cheap or inferior solution would do neither the project, nor the reputation of a group of proud professionals, any good.

Gareth Jones of Perkins Plasterers explains: “The original material that had been considered presented a high risk of failure in our view, and we were not convinced it would perform as needed, particularly for the scale and complexity of this project. So, in consultation with Seddon we decided to upgrade the specification. It soon became clear that we had made the right decision in choosing the Tyvek® and AirGuard® products. Being a school building it needed to function for the long term in a way that would keep costs down so there was no point in cutting corners in the short term. And in fact ‘corners’ were one of the key places where this material came into its own, as together with its special tapes and sealants, it has a flexibility that works brilliantly with windows and doors, or wherever there are cuts or penetrations that need to be completely sealed.”
Gareth and team were impressed by the experience of working with DuPont, “The customer support from start to finish was second to none. We had a full day’s training, plus further site visits, and very clear guidelines which helped us understand how easy the system was to work with. It was obvious even during the build that everything was performing as it should because it helped to keep out some awful weather conditions. Once fully installed and tested it gave us excellent results. The school is now open and the airtightness of the envelope is performing very well. We would definitely work with these products for similar projects in the future.”

The products Gareth refers to are Tyvek® Housewrap breather membrane, which was applied to the sports hall, and Tyvek® AirGuard® Control which was used on the main school building as a vapour control layer. These function as part of a holistic system together with specially created accessories Tyvek® FlexWrap EZ concertina-style tape and Tyvek® Double-Sided Tape, thus ensuring the integrity of the airtight seal even around awkward corners, servicing ducts and structural penetrations.

Tyvek® breather membranes are unique because of their high-quality single layer construction and are naturally vapour open while also being dependably – and lastingly – water-tight, as proven by comprehensive field tests. Tyvek® AirGuard® Control is a light-weight, easy to install AVCL which offers superior mechanical strength and is designed to reduce uncontrolled air leakage and minimise convective heat loss in roofs, walls and floors.
So, the new John Taylor Free School benefits from the best in the business. According to the RIBA report The Better Spaces for Learning published in May 2016, “Good design makes schools cheaper to run – we estimate that up to £150m annually is being spent on unnecessary services and maintenance which could have been avoided if schools were better designed.” DuPont™ Tyvek® and DuPont™ AirGuard® products can form a key part of the solution to such avoidable costs – the definition of a wise investment in quality, expertise and reliable service.
About DuPont™ Tyvek® & DuPont Building Membranes and Products: DuPont™ Tyvek® advanced building membranes are unique in the market due to their high-quality single layer construction. Tyvek®, in all its specialised versions, is naturally vapour open but also durably wind and water-tight. Lightweight yet robust, it is easy to install and offers long-term, proven reliability. Designed to protect the building envelope against the effects of weather and moisture, this family of membranes also offers optimal air-tightness and can help to improve the thermal performance, energy-efficiency and interior climatic stability.

Tyvek® is also designed to work as part of a holistic and optimal system with a range of other proven DuPont products for the building envelope, including the DuPont™ AirGuard® advanced AVCL series, the highly versatile Tyvek® FlexWrap air and water sealing tape, plus other specialised tapes and sealants. All DuPont building products come with the renowned service, expertise and technical back-up of a world-class science company.

Tyvek® is proven to simply outperform cheaper products in a complex market

September 2018

The Reality Checks Continue:
Tyvek® is proven to simply outperform cheaper products in a complex market

Following on from the revelatory results in the 2016 tests for watertightness in ‘real life’ roofs, a further 20% of roofs were opened with their membranes tested under the same strict, independent criteria. All the results from these additional tests have reinforced the initial conclusions: Tyvek® gives lasting performance and peace of mind, where cheaper membranes fail.

The percentages speak for themselves: 94% of roofs over 20 years old fitted with Tyvek® pass with flying colours. Compare that with roofs less than 10 years old fitted with other underlays, where only 21% remain watertight. The testing demonstrates why Tyvek® is such a highly trusted product.

Concerned by multiple reports of some alternative vapour-open underlays failing in their secondary water shedding role, a couple of years ago Tyvek® instigated a thorough investigation into ‘real world’ performance. These reports put the reputation of a whole class of roofing underlays at risk, and as industry codes have yet to catch up, it was right that the market leader stepped up to investigate the issue.

Qualities such as long term water hold out – which most crucially affects the homeowner – can only be effectively assessed after exposure to natural environmental stresses, both during the build and when occupied. While ageing of underlays can positively affect vapour diffusion with increased porosity, this may adversely affect the water shedding function, should the primary covering fail. This unfortunate occurrence is becoming more prevalent in today’s increasingly stormier weather. Ultimately, the primary quality in terms of membrane longevity is watertightness – an area which presents the most risk for property, insurance, and reputations.

All membrane samples were taken from the roofs and the tests were performed by an independent expert, using the EN13859-1&2 W1 classification system for watertightness. Each specimen was exposed to a 20cm water column for 2 hours to measure not only whether any leakage occurred, but how much, over what surface area and how quickly.


This established, in crucial and revealing detail, precisely how well each underlay withstood water after 5 to 10 years in a roof, or, in the case of Tyvek®, for more than 20 years. Please visit the updated page about these ageing tests, which includes a short video, for a summary of the findings. http://tyvek.construction.dupont.com/rooftest
