As the exclusive Southern African distributor of Tremco illbruck products, FG Trading offers an extensive range of top-quality sealing and bonding solutions for reliable and sustainable sealing and bonding of windows, facades and interiors.
The range includes sealants, adhesives, tapes and membranes for various specialist applications including structural glazing, insulated glass unit manufacture and weatherproofing.

Case study: Sasol Headquarters
One of South Africa’s largest new commercial projects, the new Sasol Headquarters, which is located at 50 Katherine Street in Sandton, aimed to obtain a five-star Green Star rating from the Green Building Council of South Africa (GBCSA). To ensure compliance with building regulations, particularly with regards to energy efficiency and heat gain, a durable, secure and efficient facade sealing method was required.

The building, designed by Paragon Architects, features a flush-glazed unitised curtain wall system which comprises 4 500 floor-to-ceiling panels of vision glass. Manufactured by Geustyn & Horak, the curtain wall system is a versatile means of producing a facade on high-rise buildings and encompasses aesthetic appeal, control of light and is inherently weather tight, air tight and thermally efficient.

Because the facade seal is considered a crucial factor in determining the energy performance and thermal comfort of a building, the sealing method used for the 20 000m2 glazing area was of utmost importance.

For the fabrication of the four-sided structural silicone glazed (SSG) units used within the curtain wall the high-performance, SG200 Proglaze II and SG300 Spectrem 2 were used for bonding the double-glazed units to the perimeter framing. In turn, FS550 Frame and Facade Silicone and ME220 EPDM Membrane were used for weather sealing and waterproofing the interfaces between the curtain walling and structure.

According to FG Trading’s Laura Strydom, the role of these key product solutions is to sustain the performance of the construction envelope over a multitude of joints and connections which, if not given suitable consideration, could significantly impact the glazing integrity and energy performance of the facade.

Tried and tested
During the course of 2016, Tremco illbruck sealants and membranes have also been used in various other high-profile construction projects in Sandton, including the completed Webber Wentzel Offices, as well as the Discovery Global Head Office and Old Mutual Emerging Market Offices that are still being constructed.

Tremco illbruck sealants and membranes are available for specification on AutoSpec as part of the FG Trading product library. “Apart from assisting in product selection, FG Trading also offers unmatched specialist advice and technical support, ensuring that our customers gain maximum benefit from using our products,” says Strydom.
