Created using a unique structure of interlocking concrete walls jutting out over an historic dock-front, the V&A Dundee is now one of Scotland’s most recognisable modern buildings. Opened in 2018, the structure of the design museum was created by Japanese architectural practice Kengo Kuma and Associates to mimic the appearance of a Scottish sea cliff; with world-renowned Arup providing multidisciplinary services including structural and façade engineering. Wates Construction was the main contractor for the project while Pro-Sealant Solutions Ltd, from Bellshill in North Lanarkshire, was the specialist sub-contractor responsible for sealing the building’s bespoke glazing system.
Prior to the commencement of the work on site, Pro-Sealant Solutions helped create a sample panel of the glazed, reconstructed stone façade in early 2016 for the project team to assess. The sample was constructed using DOWSIL™ 791 Weatherproofing Silicone Sealant in black for the glass to glass joints, as well as DOWSIL™ 895 Structural Glazing Sealant for a glass corner of the structure.
provided all of the technical and test data necessary to confirm the suggested DOWSIL™ products’ compatibility with the façade materials. The specified products needed to demonstrate their ability to meet the extreme weather demands of the estuary location.
Having demonstrated the suitability of the DOWSIL™ products for the job, Pro-Sealant Solutions’ installation teams were on site for more than two months over a period from the summer of 2016 to the end of the following year. It was necessary that the sealant specialists made repeat visits as different sections of the elevations were installed and came ready for glass-to-glass, and glass-to-stone sealing.
Gerry O’Brien Jnr., the son of Pro-Sealant Solutions’ founder, commented: “As a specialist in the sealing of glass façades and other flagship projects such as this, we work all over the UK and Ireland and always try to make use of the DOWSIL™ sealant range where the contract allows us.
"In addition, the fact that we are a Dow Quality Bond™ member provides an additional degree of confidence for clients and proves that our applicators are well trained and audited to meet world class application standards.”
DOWSIL™ 791 is a specially developed weather-proofing low-modulus silicone sealant: available in clear as well as white, grey, black brown, bronze, stone, buff limestone and anthracite. It is suitable for un-primed application to glass, metal, masonry and other porous or non-porous substrates, which offers +/- 50% movement of the original joint width, making it ideal for expansion, perimeter and other joints.
DOWSIL™ 895, for its part, is a specifically developed structural glazing sealant suitable for bonding glass, metal and other construction materials. It is able to provide weather resistance right up to hurricane force conditions: making it ideal for the extremely testing climate on Scotland’s east coast.
The product conforms to the European standard for structural glazing (ETA-01/0005).
