STRUCTURAL GLAZING SEALANTS FOR TABLE BAY MALL

SUPPLIED BY a.b.e.®


DOWSIL 895 structural glazing sealants, supplied by a.b.e.® Construction Chemicals, was used to seal the expansive and spectacular skylights of the new Table Bay Mall in Table View, Cape Town.

a.b.e.® is part of the CHRYSO Southern Africa Group and sole South African distributor for the Belgian-produced DOWSIL range of structural glazing sealants, insulating glass, and sealants for expansion joints on highways, airport aprons and bridges.

Grant Batty, National Manager: Silicones, Sealants and Adhesives for a.b.e.®, says DOWSIL 895 – which was specified for the Table Bay Mall skylights as well as the glazed façades around the shopping complex’s entrances – is a single component silicone sealant globally used for structural glazing.

It meets stringent European standards for structural glazing and is odourless with a non-corrosive curing system. The cured product has excellent weathering characteristics and is resistant to UV radiation, heat and humidity.”

The applicator of the structural glazing sealant for the skylights was Cloud 9 Skylights, a DOWSIL Quality Bond member.

Cloud 9 Skylights also applied DOWSIL 813 C as an exterior weatherproofing sealant to the skylights. DOWSIL 813 C is a one-part, neutral curing, low modulus sealant suitable for interior and exterior applications, such as weather seals, expansion joints, and perimeter joints in buildings and other types of structures. “It has a joint movement capability of + 50% as well as -50% and provides strong, un-primed adhesion to various substrates, including glazed surfaces, concrete, masonry, brick, wood, and some plastics,” Batty adds.

 

The application of the combination of DOWSIL 895 and 813 C at Table Bay Mall’s entrances was done by another DOWSIL Quality Bond member, CGA Fenestrations, with which a.b.e.® has also had a long-established relationship.

“With the inadequate application, even the finest sealants can fail. But now specifiers and developers are assured that DOWSIL sealants will only be applied by Quality Bond applicators who meet the company’s stringent rules of compliance. Quality Bond guarantees that the level of the workmanship and application will meet the most demanding requirements for safety and durability. Quality Bond applicators, furthermore, have to be audited annually to have their certification renewed,” Batty states.

DOWSIL also markets and promotes the services of Quality Bond members among specifiers worldwide and offers its respected technical expertise to ensure that projects are carried out according to the company’s strict quality control system. Laboratory testing on substrates to check adhesion, compatibility and staining enable DOWSIL to make formal recommendations for the product selection and use.abe-sasol-waterproof-2

“The provision of blueprint reviews, design calculations for structural and weather-sealing joints, project audits, training and warranties all contribute to the total peace of mind package now offered to specifiers,” Batty adds.

• The full ownership of Dow Corning® was transferred to The Dow Chemical Company. Dow Corning® construction products are now DOWSILTM. The two businesses will be integrated to offer an improved and expanded service to customers with a.b.e.®. continuing to serve as sole distributor of The Dow Chemical Company’s range of products in Southern Africa.
