One of the busiest buildings at the University of Dundee has benefited from a complete replacement of its waterproof roofing, with Alumasc Derbigum Olivine roofing membranes.
The project ran, which ran in August last year and lasted for six weeks, was completed on time, with no complications, after a thorough site survey to correctly identify the project needs.
During the survey, it was discovered that the roofing in place had exceeded its lifetime, and was in very poor condition.
After receiving specifications from Alumasc, the client took the opportunity to install a high-quality roofing solution that would also contribute positively to the environment.
Permatop Roofing headed up the project; Director at the company, Jim McVeagh, commented on how ‘Olivine membranes are extremely special’
“Olivine is a highly effective, durable waterproofing solution for roofs which also actively purifies the air by neutralising CO2 in rainwater,” he added.
Olivine membranes use a naturally occurring mineral upper layer that neutralises the most prevalent greenhouse gas via an irreversible chemical reaction when it comes into contact with rainfall.
This technology was developed with the objective of contributing positively to the on-going challenge that climate change poses.
The Olivine grains within the membrane decrease in size with each reaction, however, once installed, clients can rest assured that they’ll continue to work for up to 30 years before the grains will have completely reacted. Each membrane is 100% recyclable and British Board of Agrément (BBA) approved.
1kg of Olivine granules have the capacity to neutralise 1.25kg of CO2, meaning over its 30-year life time, this 600m2 project could potentially absorb nearly 3500kg of carbon dioxide.
Alumasc Derbigum Olivine roofing is ideal for warm roof applications; its high melting point ensures membrane stability in the hottest weather whilst the polyester/glass fibre reinforcement provides high tensile strength. In the middle of the summer, this was an extremely important consideration for Jim.
Jim added: “Personally, I think the technology that goes into Olivine is amazing. Anyone who chooses to install Olivine on their rooftop is actually doing something positive for the environment, while also ensuring a high quality, built-to-last waterproof solution for their roof. It couldn’t be easier, so why not?”
Approved by the BBA (Certificate No 86/1593), all Derbigum roofing membranes, including underlays and vapour barriers, are CE marked, with Declaration of Performance (DoP) certificates available.
Alumasc Roofing carefully carry out site surveys, and offer specifications, CAD/BIM calculations and designs, site reports and monitoring and roof maintenance to ensure that each and every project is executed and maintained to the highest standard.
Permatop Roofing are an approved contractor to install Alumasc products, and won the tender for this project based on their experience and expertise in this type of refurbishment work.
Jim continued: “Permatop will only work with the best quality roofing products, which is one of the reasons why we work with Alumasc: the products are of excellent quality, great to work with, and the company is overall very reliable.”
