Class 2 Rooflight, Impact Test

Class 2 Rooflight, Impact Test

One of our ongoing projects Lakeside House includes Schüco FWS 60 rooflights which must meet Class 2 for safety and fragility of overhead glazing. For that reason we constructed a test rig which we then tested in accordance with TN 66 and TN 67 where the rooflight is assessed in 3 ways:

• Soft body impact test – Where a 300mm cylindrical sand bag weighing 45kg is dropped from a height of 1200mm.
• Hard body impact test – A 100mm diameter steel ball weighing 4.11kg is dropped from a height of 1200mm.
• Static load test – For this test the glass must be broken if not already, then a static load of 180kg is placed on the test rig for 30 minutes.

We are pleased to announce the rooflight successfully passed in all areas, images of the testing can be found below.
