Synseal Traditional Roof Lanterns
have a 10 year guarantee, with manufacture and supply carried out under certificated
BS EN ISO9001:2000 quality management systems.
Technical compliance – UK specification Building Regulations Part A1 concerning loading of buildings is a key reference document when designing glazed roof structures. All weather parameters for specific site postcode, including an assessment of the local terrain and topography, prevailing wind speeds and pressures, are taken into account to determine how the roof will be constructed.
- Global roof sare designed to meet the requirements of: • BS 8118-1:1991
- (Code Of Practice For Structural Use Of Aluminium) • BS 6399-2:1997
- (Code Of Practice For Wind Loads) • BS 6399-3:1998
The Global roof has been exhaustively tested and thesystem has received British Board of Agrément (BBA) accreditation.
A standard Georgian conservatory was independently assessed by façade-testing specialists Wintech Engineering to prove that Global can withstand the most extreme weather conditions, with market-leading performance results that far exceeded expectations.
BBA – test achievements
- Water penetration test at 300 Pascals: PASSED (equivalent to a Force 9 severe gale)24 hour water penetration testing was carried out, during which the roof was deluged with 113 inches of water, more than twice the average annual British rainfall.
- Uplift test at 900 Pascals: PASSED (equivalent to wind speeds at 85 miles per hour)
- Load test of 120kg per m2: PASSED (equivalent weight of 4 feet of snow per m2)
Wintech Engineering – test achievements
Wind resistance testing using a modified DC6 aircraft engine and applying negative pressures to simulate increasing wind speeds.
- Wind speed of 90 miles per hour: PASSED (exceeding the UK’s great storm of 1987)
- Wind speed of 130 miles per hour: PASSED (new record for a UK-manufactured conservatory)
- Wind speed of 160 miles per hour: PASSED (equivalent to a devastating Force 17 hurricane) Structural integrity testing was then carried out on the same conservatory, after wind testing, with Win tech applying negative pressures to simulate increasing snow loadings.
- Structural integrity testing: PASSED (equivalent to 9 feet of snow per m2)
