How Thermal Glass Coat works.
It’s a liquid coating which is applied to your existing glass. This coating is very new technology that transforms your windows into thermal insulation barriers, blocking Infrared Radiation keeping heat inside in winter and outside in summer. It is a liquid “painted” onto your windows which dries to leave you with a clear view.

A couple of comparisons ...

Comparing Thermal Glass Coat as a retrofit Double Glazing alternative is easy, but Window Insulation Film is tricky because there is a massive variance in quality, performance and cost. You can get high quality Window film with comparable performance, but it does cost a lot more.

In Clarke’s beach, a couple were quoted $9,000 for 2 very large, high windows in their lounge to be Double Glazed. We did their whole house for $6,000. High performance Window Film would have cost around $11,000. The job took 2 days. After the 1st day, in the lounge we’d only done the 2 large, high windows. The next morning, the client said “that stuff is amazing, I turned the heat pump down 3 degrees last night, and you haven’t even coated the other windows in the lounge yet”.

In Mt Wellington, a Father of a local Church got 3 Double Glazing quotes for the Church’s home. The lowest was $19,000. We did it for $4,000. High performance Window Film would have cost around $7,000. He reported … “I do not use any heating during the day as it is no longer necessary.”

Thermal Glass Coat is priced at a fraction of the cost of installing retrofit double glazing; it is quick and quiet to apply; and it is guaranteed for 10yrs. It is the perfect double glazing alternative for window insulation and UV protection.

Things to consider other than price…

Retrofit Double Glazing

There maybe access equipment costs to be added as well.

It’s messy, stressful and disruptive to home owners.

Glass is incredibly heavy. Adding a second pane to many window frames is fraught with unforeseen problems. Damage, leaks, warping and bending. This is glossed over my many retrofit double glazing installers because it doesn’t become an issue until 2 or 3 years after the install.

Window Insulation film

The applicators have to leave visable join lines on large windows.

Film is known to crack, peel and bubble.

It’s known to have durability issues in hot environments and can even break windows.

We work on the inside, so usually, no access equipment is required (unless you have really high windows inside).
