Crittall Windows has introduced Fineo vacuum insulating glass across its entire range of steel window and door systems, expanding the glazing options available to architects and specifiers seeking improved thermal and acoustic performance without compromising slim steel profiles.
Manufactured by AGC Glass Europe, Fineo uses a microscopic vacuum between two glass panes to reduce heat transfer. In its Fineo 8 configuration, the glazing measures just 7.7 mm in thickness and achieves a centre-pane U-value of 0.7 W/m²K, with light transmission of approximately 80%.
The system also provides a sound reduction rating of 35 dB under laboratory test conditions. Actual acoustic performance will depend on the complete window assembly and installation.
The thin construction offers particular advantages in refurbishment projects and applications where conventional insulating glass units may be difficult to accommodate. It also allows architects to retain the characteristic narrow sightlines associated with steel windows while improving the thermal performance of the glazing. 
According to Crittall, Fineo is 100% recyclable and supplied with a 20-year warranty. The expanded offering provides another option for projects balancing energy efficiency, acoustic comfort and the architectural character of steel-framed glazing.
