S E C T I O N 5 VALLEY Where the valley meets the eaves beam, the angle between the eaves beam sections should be 90˚ as shown in diagram A). The situation as shown in diagram B) should be avoided especially with glass roofs:- 7 SERIES LIGHT BAR DIAGRAM A) 83 100 83 Transom/Victorian Georgian Starter Note: add 5mm for chambered top capping heights. Minimum return 300mm 7 SERIES BAR Valley on 90˚ eaves beam 83 100 83 DIAGRAM B) AVOID IF POSSIBLE Transom/Victorian Georgian Starter Note: add 5mm for chambered top capping heights. 7 SERIES+REINFORCING BAR Valley on 135˚ eaves beam This method requires a fabricated valley manufactured by Ultraframe Transom/Victorian Georgian Note: add 5mm for chambered top capping heights. 7 SERIES+BOLSTER BAR For information on maximum valley spans please use the UK Structural Design Guide (electronic version). GLAZING BARS There is a choice of 2 glazing bars - 7 light and 7 standard. 7 standard is available with inserts for additional strength or with bolsters for additional performance. When ordering a complete roof, it is not necessary to state the glazing bar, as Ultraframe will select the appropriate bar for the roof in question. However, if required, further information on glazing bar spans can be found in the UK Structural Design Guide (electronic version). 168 73 73 Transom/Victorian Georgian Note: add 5mm for chambered top capping heights. 182 19 © ULTRAFRAME 2000
