How double glazing works.

Timber Retrofit double glazing uses an innovative and efficient system designed to create a warmer, drier, healthier and quieter home for you and your family.

Timber Retrofit replaces your existing single glazed glass with new sealed double glazed units which are made of two panels of glass bonded together with a thermal spacer creating a cavity that is filled with either air or argon gas that provides an insulated barrier, keeping the cold out and the warmth in.

Timber Retrofit is an authorised licensed installer of Thermawood, New Zealand’s most advanced double glazing system for existing timber windows and doors.

Each double glazed unit is custom made to you and your home allowing you the greatest benefits. Our system allows you the comforts of double glazing without compromising originality and character of your home.
