SIKA SARNAFIL EXPLOSIVE SUCCESS FOR ROYAL GUNPOWDER MILLS HERITAGE ROOF REFURBISHMENT
The high-quality roofing system was chosen after the project ’ s main contractors Courtenay Builders Limited were impressed with the results from similar Sika Sarnafil projects . They also entrusted Contour Roofing with the specification and installation after seeing its award-winning track record with Sika Sarnafil .
The Royal Gunpowder Mills heritage site had
Sika Sarnafil products installed to guarantee a stunning aesthetic and durable roofing solution .
A historic and archaeological treasure , the Royal Gunpowder Mills heritage site in Waltham Abbey , Essex , has been given a new lease of life with a stunning and sympathetic roof refurbishment .
Consisting of listed buildings , ancient monuments and natural aspect features , the site is a well-loved attraction . A busy hub of activity , it attracts thousands of visitors every year , with exhibitions and a programme of hands-on activities for school groups .
With previous roof coverings across the site ’ s buildings close to derelict , a new roofing system was needed that would both guarantee a durable solution and fit with the aesthetic of the heritage buildings . To meet those needs , Sika Sarnafil G410-15EL FSA Lead Grey was specified alongside Sarnavap 1000E air and vapour control layer .
As a site once home to tonnes of explosives and with visitors in throughout the refurbishment , the project proved challenging , requiring extensive attention to health and safety . A strict ban on naked flames and hot works meant that the plywood boards had to be primed immediately after installation and before exposure to any wet weather . The specification therefore considered this and the original system , which would have needed a completely dry substrate , was switched to a loose laid polyethylene air and vapour control layer that was more equipped for a faster installation in the expected conditions .
Securing a 20-year Sarnafil guarantee , the newly refurbished roofs have not only met the client ’ s need for a stunning aesthetic , but have also provided a durable weatherproof roofing system – upholding the heritage charity ’ s mission to conserve the site for the benefit of the general public .
