Fully Supported Rooflight
This is a compact and elegant solution where the glazing bar is fully supported. The minimum suggested pitch is 15 degrees and the system can be double glazed with 24mm to 28mm units.
The Trilight System requires fixing shoes at approximately 1 metre centres.
If used in a non-supported aplication the following span chart applies.
| Working |
| PT1 Glazing Bar|| PT1 Glazing Bar|
| n/m2|| 600mm Centres || 750mm Centres|
| 1250|| 1500|| 1400|
| 1500|| 1400|| 1300|
| 2000|| 1300|| 1200|
Spans should be measured along the pitch.
Please note that these charts are indicative and should be used for design purposes only.
