Choosing the right window tint isn't just about looks or privacy. It also has to suit your glass type so it performs well and lasts. The wrong pairing can lead to costly issues like reduced efficiency or even cracked glass. If you're upgrading your home or office, understanding the nuances of different glass types is essential.
Tempered glass
Tempered glass is often used in commercial buildings and is known for its strength and safety features. It undergoes a heat treatment process that makes it highly durable, and most window tints are compatible with it. Ceramic tints are an excellent choice for their superior heat rejection and UV-blocking capabilities. Metalised tints offer added durability and a sleek look, while dual-reflective tints balance aesthetics with functionality.
Single-pane float annealed glass
If you have single-pane glass windows, you're in luck, they're one of the easiest types to tint. Most residential and commercial tints work well on single-pane glass. These tints enhance energy efficiency, block harmful UV rays, and improve indoor comfort. Ceramic tints are a reliable choice thanks to their non-reflective appearance and high heat-reduction properties.
Double-pane glass
Double-pane glass, found in many modern homes and offices, offers excellent insulation. However, its construction (two layers of glass separated by a sealed air or gas space) requires careful tint selection. Tints with high absorption rates can trap heat between the panes, causing thermal stress that may result in cracks.
If you want to reduce heat entering the building, the best application for double glazing is an external window film. We offer a clear IR film that reduces heat by 70%, or a tinted/reflective film that delivers a minimum 70% heat reduction. Internal films can achieve 50–60% heat reduction. The best internal option is a metallised reflective tint, the less the film absorbs, the better. Films that absorb too much heat can build up radiant heat in the glass, sometimes to the point where you can't touch it.
Low-E glass
Low-E (low emissivity) glass is coated to reflect heat and improve energy efficiency. It's used widely across Melbourne, often in combination with double glazing. Some tints can interfere with the Low-E coating, so it's essential to select a tint explicitly designed for compatibility. Spectrally selective tints are an excellent choice, they enhance thermal performance without disrupting the original Low-E features.
The importance of professional advice
Choosing the right window tint isn't a one-size-fits-all decision. Each glass type has unique requirements, and using the wrong tint can lead to a range of issues. Consulting a professional ensures your tint enhances functionality and preserves structural integrity.
Glass type also drives which heat-control product is safe to use — we cover that in our guide to solar and thermal window film.
