High speed wind and rain tests on the Ubbink Ubiflex Flashing system 1 Introduction This report details testing undertaken on 30th of May 2008 to assess the performance of Ubbink Ubiflex flashing in conjunction with two sealant compounds, firstly Ubi-Seal a 15mm wide butyl tape applied in a single layer and secondly High-Tack, an adhesive sealant compound. The Ubbink Ventilated Dry Ridge System was also tested. The systems were tested under high windspeed conditions. The testing was carried out at BRE, Bucknalls Lane, Watford, WD25 9XX, UK. The client for these tests was Mr Barry Donaghue of Ubbink...

High speed wind and rain tests on the Ubbink Ubiflex Flashing system 2 Details of testing carried out The objective of the testing was to assess the performance of the Ubbink Ubiflex flashing in conjunction with two types of sealant compound under high wind speed conditions and also to assess the performance of the Ubbink Ventilated Dry Ridge System. The test systems were installed on a 2m x 2m (plan dimensions) 30° pitch test roof which was mounted at the end of the BRE wind tunnel. The flashings and sealant were used in conjunction with a chimney constructed from plywood and lined with brick...

High speed wind and rain tests on the Ubbink Ubiflex Flashing system 3 Details of the test products The chimney and tiles were installed by Ubbink at their plant and the finished assembly was shipped to BRE for testing. Each side of the roof was tiled differently and opposite sides of the chimney the flashings were fixed with different sealants. The chimney consisted of a plywood frame surfaced with brick slips. The ridge was of three sections of Marley Segmented ridge tiles two to one side of the chimney one to the other side these were secured with metal ridge clips. Side 1. Double pantiles...

High speed wind and rain tests on the Ubbink Ubiflex Flashing system 4 Test results 4.1 High Speed Testing The roof was tested with wind approaching from a range of wind directions. With wind blowing on to the gable end (wind direction 0°), on to the corner at 45° and on to the eaves (wind direction 90°). Log sheets of the tests are given in Annex B. The testing was also filmed and the wind speeds attained were indicated by holding a card in front of the Camera. Any tiles displaced during testing were reset before starting the next stage of testing. 4.1.1 Testing of side 1. Double pantiles with...

High speed wind and rain tests on the Ubbink Ubiflex Flashing system 4.1.3 Testing of Ubbink Ventilated Dry Ridge system During the course of the testing described above there was no visible damage to the Ridge tiles or to the Ubbink Ventilated Dry ridge system. To put a wind speed of 49m/s (110mph) into context, from BS6399: Part 2 (the British Standard for wind loading on buildings) the design wind speed to be expected on a two-storey house in the London area in a fifty year design life would be of the order of 25m/s (56mph) to 35m/s (78mph) (depending on factors such as the roof height, distance...

High speed wind and rain tests on the Ubbink Ubiflex Flashing system 5 Summary The results from these tests on the Ubiflex Flashing surrounding the chimney show that the flashing and the two types of sealant used will resist wind speeds of at least 49m/s (110mph) without failing or demonstrating any other visible signs of distress. It is very likely that these systems will be able to withstand higher wind speeds than the maximum applied during the testing, although this was not demonstrated in the testing because the maximum speed of the wind tunnel was reached. Testing also demonstrated that...
