Retrofit Double Glazing

No more cold, damp and drafty windows with Thermoglaz retrofit double glazing. Extra comfort that’s 100% guaranteed.

Nothing beats a warm & comfortable home – yet thousands of New Zealander’s still suffer from cold homes, endless condensation and noise – all needlessly.

This led Thermoglaz to pioneer and develop the best retrofit double glazing system available today for timber and aluminium windows.

Whether you’re looking at retrofit double glazing for your timber framed windows, or aluminium framed windows; we’ll provide you the most professional and reliable solution available. Furthermore, we’ll guarantee it stands the test of time.

We deliver exactly what we promise and don’t cut corners. Thermoglaz is a proven brand you can trust – and we guarantee it.
