The certified scope
We process coated glass as a Guardian-certified fabricator, certificate HA220726. The certified scope is SunGuard SN, DS and HP, plus ClimaGuard coatings, at 4, 6 and 8 mm: mechanical processing, heat treatment, and insulated-glass assembly.
We procure the coated glass ourselves and fabricate it here; a quotation from this page prices supply and fabrication together. Certification is renewed annually; what it attests is processing to Guardian’s guidelines. A spec outside that scope, a different thickness or another maker’s coating, is not a wall: name it in the quote request and the answer comes in writing. What each certification covers →
