CONTRAFLAM One
One Chamber, All Ratings
Driven by sustainable innovation, CONTRAFLAM One represents the industry’s most advanced product since the invention of fire-resistive glass. Vetrotech’s over 40 years of interlayer chemistry expertise and dedicated decade of research, development, and testing led to the creation of HYBRIDCORE Technology, the key to CONTRAFLAM One’s markup of just two 6mm lites of glass and one intumescent chamber for all fire-resistive performance ratings 60-120 minutes. Where the competition achieves higher ratings by adding more chambers, thicker or more glass lites, CONTRAFLAM One achieves enhanced performance and aesthetics while reducing raw materials, and in turn, embodied carbon and product weight.
CONTRAFLAM One is clearer, lighter and more sustainable than any other fire-resistive glass on the market.
See how CONTRAFLAM One stacks up against the competition
Clearer, less obstructed views
CONTRAFLAM One boasts Visible Light Transmittance as high as 90%. In fact, its VLT is higher than competitors for all ratings. And the maximum exposed area for 120 minute products is 44.9 square feet.
Allowing more daylight to enter and reach deeper into facilities as well as offering larger views uninterrupted by framing is consistent with biophilic design principles and can improve the mental and physical health of the buildings’ occupants.
Lightest weight for fastest, easiest installation
Fewer panes of glass and thinner assemblies at higher ratings make CONTRAFLAM One products lighter than any competitors by as much as 31%. Add to this a tolerance of temperatures ranges from -40F to +140F and use of strong tempered glass and you have a product designed to make everyone’s job a little less stressful. Worry-free transport with easier handling and faster installation helps projects stay on budget and on schedule.
Lighter impact on the environment
Sustainability is a core value for Vetrotech, as it is for all Saint-Gobain companies. In addition to increasing clarity and reducing weight, CONTRAFLAM One is revolutionary for its sustainable properties. It comes down to the principle of embodied carbon. Embodied carbon represents carbon emissions released during the lifecycle of building material, from the extraction of the raw materials needed to produce it to processing and disposal of waste at the end of its useful life. Between 65% and 85% of total embodied carbon emissions are produced during the product phase – raw material acquisition, supply and transport and manufacturing.
Because CONTRAFLAM One requires less glass in production than original CONTRAFLAM, its embodied carbon is up to 35% less for the 120 minute product.
