Christoffel Australia is a family owned and run business which was first established in 1986. Since then we’ve successfully manufactured and sold proudly Australian made uPVC windows and doors.
Our windows are built to be low maintenance, energy saving and noise reducing, and we can offer a Weighted Sound Reduction Index (Rw) of 45 in a single window. They can also provide a Uw energy rating of 1.0, with a Solar Heat Gain Coefficient (SHGC) up to 2.0 possible. You can choose to enhance your windows or doors with fireproofing properties, with a Bushfire Attack Level of up to BAL 40.
With our windows, you don’t have to sacrifice style for function. We offer a variety of colour finishes, including anthracite, black, golden oak woodgrain, ivory, signal grey, and white.
