Trosifol® announces the launch of SentryGlas® TW ionoplast interlayer

SentryGlas® TW (Translucent White) combines all the technical benefits and structural properties of SentryGlas® ionoplast interlayer i.e. safer, lighter, tougher structural glass solutions with a variety of white shades that provide both a pleasing aesthetic effect and a sense of privacy.

The official launch of the SentryGlas® TW interlayer follows a number of successful building projects that have benefited from the new interlayer, including the College Football Hall of Fame and Chick-fil-A Fan Experience in Atlanta, Georgia, USA.

This three-storey, 94,000 square feet (8,733m2) museum uses SentryGlas® TW interlayer for the exterior glass façade and the interior entrance tunnel ceiling.

Jennifer Schneider, Structural and Security Market Manager, Trosifol® Business explains:

“Architects and glazing contractors that desire a structural interlayer combined with a white colour effect now have an option.

They can now specify an interlayer with the proven technical advantages and structural properties of SentryGlas®, while also delivering privacy and a translucency effect.

SentryGlas® TW provides a unique combination of colour and structural properties that no other current PVB interlayer can match.”

SentryGlas® TW interlayer gives architects much more freedom in their designs, combined with the improved structural properties of SentryGlas®.

For example, the interlayer’s stiffness and strength (SentryGlas® ionoplast interlayer is 100 times stiffer and five times stronger than traditional PVB) help to create lighter and safer structural glass that can withstand greater loads and harsher conditions.

As well as providing excellent post-breakage performance, SentryGlas® TW interlayer offers excellent durability and edge stability too, even when exposed to extreme weather conditions – an important consideration in minimally supported applications such as glass canopies, balustrades, exterior façades and flooring.

Available to laminators on roll, SentryGlas® TW ionoplast interlayers can be stacked to achieve different visible light transmission properties, giving designers even more scope.

For example, a 65% visible transmittance (Tvis) is achieved by stacking two plies of 31 mil (0.80 mm) thickness interlayer together during the lamination process. Higher or lower Tvis values are achieved by varying the number and thicknesses of the plies.

“In accelerated outdoor weathering tests, SentryGlas® TW interlayer showed no signs of discolouration after 10 years,” adds Jennifer Schneider.

Like SentryGlas® ionoplast interlayers, SentryGlas® TW interlayer has achieved Miami-Dade County approval for use in hurricane-impact-resistant glazing applications.

SentryGlas® TW interlayer is available on rolls in widths of 122 cm (48 in), 153 cm (60 in) and 183 cm (72 in), in lengths of 200 m (656 ft). 153 cm (60 in) width is also available in 50 m (164 ft) roll lengths.
