Wind suction tests to determine the resistance to wind load on bonded or mechanically fastened roof waterproofing systems is one of the first services that I.F.I. has been providing to industrial clients since its foundation. Over the years, we have constantly updated our know-how and test rigs, in order not only to conduct tests in accordance with the current guidelines and standards, but also to broaden our range of services.
As a result, we do not only test flexible sheets for waterproofing in accordance with EN 16002 and EN 17686, but we also conduct tests on wind permeable systems and green roofs.
Whether according to guidelines or to standards: after the tests, you will receive a report that documents the set up, the damage or the results and includes information on the characteristic load.
*** NEW ***
We now also offer the option of having the test set up for the wind load tests made by a local authorised master roofer, so that you no longer have to send employees to do this and can save costs. If you are interested, do not hesitate to tell us and we will take your wish into account in our quotation.
For mechanically fastened flexible sheets for roof waterproofing, failure of the test specimen is tested in accordance with EN 16002 in the I.F.I. roof and façade test rig. With the test chamber having been extended to 6 m x 2.5 m x 0.75 m, we are able to test large sheets as well. Using a computer-controlled fan combined with a pressure control flap, we build up a defined pressure-time curve in the test chamber, thus allowing for a realistic simulation of the gust effect.
Until recently these systems were tested on the basis of EN 16002. End of 2022 the EN 17686 was released, providing specific instructions regarding the test equipment and test procedure for roof build-up systems with bonded waterproofing systems. Our test rig complies with the requirement of EN 17686, so that you can be sure that your systems are tested according to the latest standards.
For tests on wind-permeable systems such as roof tiles, roof shingles and paving slabs, the pressure equalization between the top and underside of the roof element must be taken into account. For these systems too, we can offer you individual testing and evaluation options.
On behalf of our clients, we also determine the positional stability of green roof structures for inverted roofs.
For this purpose, the pressure equalization between the roof cladding and the surroundings and a wind load reduction factor are determined in order to be able to calculate the actual uplifting wind force acting on the green roof components. The appropriate ballasting for the roof is then determined on this basis.
