Dan Bleoju, the parkade manager for the West Edmonton Mall sprang into action to find the right solution when leaks in the skylights began to occur over the World Waterpark and Mayfield Toyota Ice Palace. He originally tried different roofing membranes with neutral cure silicones; however, this provided only a temporary fix and the leaks persisted.
To handle the extreme movement required for the application, Bleoju decided on Tremco's Spectrem Simple Seal, a high-performance silicone extrusion. A custom profile of the product was created to provide a perfect fit matching the width and shape of the existing mullion. Simple Seal was also a perfect match for Alberta's climate which tends to be very cold mornings in the spring and rising temperatures throughout the day.
In conjunction with Simple Seal, Tremco's Spectrem 2 Silicone sealant was applied over the skylight's mullions that was no small task but this solution offers long-term durability and refreshed aesthetics significantly cheaper than replacing the full fenestration system. Simple Seal provides an added benefit in that it is easily patched and repaied, requiring an overlap of silicone sealant approximately one inch onto the existing membrane.
