The Global Conservatory Roof is now the UK’s market-leading aluminium and PVC-U conservatory roof system. It was designed without compromise and tested to the highest standards.

The Global conservatory roof has been exhaustively tested and the system 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.

Direct Roof Systems is the only manufacturer of the Global conservatory roof system in East Anglia. It delivers security and practicality in one great design, because of the meticulous attention to detail the global conservatory roof system allows you to be safe in the knowledge that you have a conservatory roof of quality.

BBA – test achievements: Snow load capability > 2.7

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 speed resistance > 250 kph

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 Wintech applying negative pressures to simulate increasing snow loadings.
Structural integrity testing: PASSED (equivalent to 9 feet of snow per m2).
