Safetyline offers thermally broken frame options — the SJ Thermique and SJ Espacer, that reduce heat transfer across the frame for improved winter performance. For maximum glazing efficiency, vacuum glazing is available as an option comparable to conventional double glazing in terms of U-values, in a much slimmer profile, reducing heating loads in Melbourne’s cold winters without added frame depth. Combined, these options support NCC Section J compliance for Victorian residential and commercial projects.
