Weatherproofing building facades against wind-driven rain is a major challenge that has always faced the building industry. Each year, millions of dollars are wasted on the repair of water-damaged interiors and reconstruction of leaking facades. Despite this, many architects and builders still underestimate the effects of wind and rain and how they can interact with the design details in a facade.

Vipac's facade engineering division encompasses a test laboratory, simulating a wide range of wind and rain conditions on full-scale test models of facades or existing buildings. Besides static pressure chambers and the AAMA Aeroplane Engine methods, Vipac operates the well-known SIROWET testing system. SIROWET is a thoroughly proven building facade performance testing technique to ensure the lifetime of building facades and is routinely used on many major building projects. It verifies strength and serviceability of a particular facade including air infiltration and water penetration.

Vipac is an independent tester of facades, holding Australian NATA laboratory accreditation for such tests. Extensive experience with a wide range of manufacturer's designs and client requirements has been gained over the past 30 years through involvement in an impressive range of major facade projects throughout Australia and South East Asia.
