How Good Are Our Conservatories?

Thermally Efficient - uPVC Frames

Our Lean-to uPVC conservatories have been updated to meet modern standards. This means that they achieve A+ standards of thermal efficiency.


Global Roof System Standard On All Our Conservatories. 

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 )

The Global 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.

Wind speed resistance > 250 kph

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