First Surface Ceramic Frit

In the not too distant past the application of ceramic frit on first surface building exteriors would result in weathering from the elements. Goldray saw this challenge as an opportunity, and were able to obtain a ceramic frit to be applied on the first surface of glass.

In addition to more vibrant images, the shading coefficient is increased and most importantly glare is significantly reduced. Goldray's First Surface Ceramic Frit has encouraged the specification of glass, which as a building material offers design flexibility.

A benefit of first surface ceramic frit is it's ability to prevent bird strikes. Bird Friendly glass is quickly becoming common request within the architectural industry as millions of birds are killed every year due to impacts with reflective building materials.

Features & Benefits

  • First Surface Ceramic Frit can be applied to glass for a cost-effective, low-maintenance solution to design needs as well as acting as a bird collision deterrence feature.
  • Goldray products produced with First Surface Ceramic Frit are highly durable, long lasting and abrasion resistant.
    It is available in laminated or monolithic form.
  • Studies have shown that patterns covering as little as 5% of the total glass surface can deter 90% of bird strikes under experimental conditions.
  • Most birds will not attempt to fly through horizontal spaces less than 2" high nor through vertical spaces 4" wide or less. Goldray recommends that patterns on glass are designed to follow the 2" x 4" rule.
