Fenzi North America has added Fenzi Poliver Polyurethane to its list of IG sealants. Fenzi Poliver is a two-part polyurethane especially formulated for sealing insulated glass and for use in commercial and residential window application. Available in 55-US gallon drum and pail kits, Poliver is for manual and robotic line sealing in traditional polyurethane viscosities and varying curing times to meet customers’ needs.

Blast, impact and hurricane resistance

Developed specifically for in-plant two- and four-sided structural glazing and curtain wall applications, Proglaze II Structural Silicone Sealant, from Tremco Commercial Sealants and Waterproofing, is a two-part, high-performance, high-modulus sealant that cures to a tough flexible rubber when mixed through a pump.  Proglaze II provides the superior quality and performance needed to meet hurricane, impact and blast resistance requirements.  A shortened cure time also reduces glazing/sealing production time, and snap time is as low as 30-60 minutes.

Fenzi North America has added to its product base with the addition of the Chromatech and Chromatech Ultra Stainless Steel warmedge spacers. Manufactured by Roll Tech, a Fenzi-owned company, these spacers are available with corner keys and connectors for those wishing to bend on bending equipment. With the ever-changing need to meet more stringent energy codes, the Chromatech line of stainless spacers meets the need for better sightline temperatures - both in excess of 17 per cent when compared to traditional aluminum. Both Chromatech and Chromatech Ultra spacers are available in a wide range of air space widths. The Chromatech Ultra has a polycarbonate bridge across the top, available in traditional white, grey and black colours.

Air and water barrier
dowcorning.com/construction
Dow Corning Corporation has introduced an air and water barrier system. Evaluated by the Air Barrier Association of America (ABAA), the Dow Corning Silicone Air Barrier System is a suite of compatible high-performance silicone technologies designed to work together to better protect the entire building envelope and to improve the energy efficiency of buildings. The system has passed NFPA 285 and is NFPA Class A/UBC Class 1 per ASTM E84. It can be used on both new construction and building renovation projects, and its low-VOC formulation makes it ideal for green construction. The Dow Corning Silicone Air Barrier System includes Dow Corning DefendAir 200 – a water-based, 100 per cent silicone, liquid-applied, air and water barrier. Dow Corning Silicone Transition System features 100 per cent silicone rubber strips and corners that are easy to install with silicone sealants (not mechanical fasteners), this system forms a continuous airtight transition at interfaces, including those that will experience large amounts of building movement.

Quanex Building Products is now Bostik’s exclusive sales force for its insulating glass sealants in North America. Quanex will carry Bostik sealants under the Edgetherm brand name, including Edgetherm 3500 single-part butyl rubber-based sealant, Edgetherm 3400 hot-applied desiccant matrix, Edgetherm 3100 and 3000 one-component hot-melt butyl sealants. Edgetherm 3500 is a single-part butyl-based sealant that sets quickly from its molten state, allowing units to be moved from their assembly locations between two and five minutes after application and glazed the same day. Edgetherm 3400 is a hot-applied desiccant matrix for sealing the airspace of an insulating glass unit, offering optimal absorption for both existing and invasive moisture.

Secures the window-to-wall connection
www.tremcosealants.com
Proglaze ETA, manufactured by Tremco Commercial Sealants and Waterproofing, is a patented transition assembly composed of pre-engineered, finished aluminum and silicone materials that are mechanically attached to the window and/or wall’s structural framing to ensure a durable connection and seal. The system’s design absorbs wind-loading stresses and movement caused by thermal expansion and contraction, vertical displacement, lateral shear and seismic conditions. The translucent silicone material allows the installer and/or inspector to see through the gasket to verify the recommended amount of sealant is properly applied to ensure an effective seal is achieved, while the ribs of the gasket’s design ensures a minimum sealant thickness.
