We offer a 35mm glazing option with an increased height glazing bar to accommodate the extra 10mm of glazing. This allows the use of the same top cap as the 25mm option to eliminate the usual ‘squat’ top cap.

Rather than taking the short cut used by some who simply use the same glazing bars and just reduce the depth of the top cap. This was an important consideration in the design, because as with all our new product developments, we researched what the market wanted, and the squat top cap was flagged as the main reason people were shying away from greater polycarbonate depths.

The other benefit to the increased bar height is that even greater spans can be achieved. By using 35mm polycarbonate with an increased glazing bar height, we are able to offer even greater spans than our current structural recommendations, just by upgrading the glazing specification!

Of course as well as the additional performance in terms of strength and heat retention, customers choosing the 35mm option will also be well placed to stay ahead of potentially more stringent regulations on the thermal efficiency of conservatories.
