InsulCool Ultra Pro 76: New Soft Coat IGU Delivers 70% VLT with U-Values to 1.29 W/m²·K
Cooling Brothers Glass Company has added a new configuration to its InsulCool Ultra Pro series — the Ultra Pro 76 — a dual silver soft coat IGU engineered for high visible light transmission without compromising thermal performance in cold-climate and high-performance commercial applications.
What Is the Ultra Pro 76?
The InsulCool Ultra Pro 76 is a soft coat, magnetron sputtered Low-E IGU make-up designed for specifiers who need maximum visible light transmittance alongside the low U-values required in climate zones 6 and 7. With a visible light transmittance of 70% in 6mm configurations and 69% in 8mm, the Ultra Pro 76 addresses a common specification challenge: achieving daylight performance targets without sacrificing the thermal envelope.
The product is available in both air-filled and argon gas-filled configurations, in 6mm and 8mm substrate options, paired with a 12mm cavity and clear backing glass. For projects requiring maximum thermal performance, the Ultra Pro 76 coating is also available in a triple-glazed configuration through Cooling Brothers' IGU line.
Performance Data
All values are calculated to NFRC 2010. Centre-of-glass performance across the four standard double-glazed make-ups is as follows:

Where Ultra Pro 76 Fits
The Ultra Pro 76 is positioned for projects in Victoria, Tasmania, alpine regions, and other climate zone 6–7 locations where heating load and condensation control are the dominant energy performance drivers. It suits high-rise residential towers requiring NCC 2022 Section J or Volume 2 / H6 compliance, commercial facades with daylighting performance requirements, heritage-adjacent projects where high VLT is a design or planning consideration, and any specification where a sub-1.30 U-value is required alongside 70% visible light transmission.
When paired with a warm-edge spacer system — available from all Cooling Brothers manufacturing locations — edge-of-glass thermal bridging and condensation risk are further reduced beyond the centre-of-glass values shown above.
Specifiers working across a broader thermal range should also consider InsulCool Ultra Cool-E for climate zones 5–6, or InsulCool Ultra Plus for projects requiring the lowest available U-values.
