We've seen the difference double glazing makes. And we want you to experience it too.

No one deserves to live in cold, damp conditions.

Your home should be warm and peaceful, a place you can relax without cool drafts and road noise to contend with.
Unfortunately, this is the reality of life without double glazing.

In 2004, John Mason set out to change this.

What began as a small retrofit request for a friend, has turned into a passion to see homes and lives transformed with the benefits of double glazing.

What better way to fulfil this desire to retrofit New Zealand with genuine double-glazing, than by partnering with family-owned retrofit double glazing businesses already established within their local communities?

Now, 19 years on, the retroGLAZE® network of retrofit businesses are on a mission to deliver quality solutions that improve the health of homes all over New Zealand.

Experience the difference for yourself and improve the warmth, security and comfort of your home with retrofit double glazing.
