WHY BUY JOINERY FROM US?
Ameribuild offers windows and doors with more standard features, higher performance, and comparatively lower cost, than nearly all other joinery companies currently operating in New Zealand.
Blast past the Building Code
Our entry level uPVC windows already exceed the Building Code updates by at least 26% for all climate zones. That makes our uPVC joinery the most affordable and energy efficient available, all at a cost comparable to thermally broken aluminium. It's safe to say our uPVC double glazing is the best value for money in New Zealand.

R values for products sold by Ameribuild represent whole window (Rw) values, not just the glass or frames by themselves, based on metric NFRC testing data. European testing methods may yield different results. Other data sourced from publicly available sources, including MBIE and BRANZ. All data was correct at the time of publication.
Save time and money
No on site measuring is required, since we order based on the rough opening/box size measurements shown on the plans, with allowances to ensure a proper fit – every time.
This means you can place your order as soon as your building consent plans have been finalised, before you even start framing. Plus, all joinery arrives on site fully assembled and glazed, installing quickly with fixing fins.


Enormous capacity
Ameribuild supplies new construction uPVC joinery made by Sierra Pacific Windows in the US, who currently produces ~20,000 uPVC windows and doors a month.
This means we’re able to supply joinery to building projects across all of New Zealand, no matter the size. Whether you need 5, 500, or 5,000 windows, we have the capacity to deliver.
Order in bulk to maximise savings
If you build a large number of the same floorplan throughout the year, you can order in advance and in bulk. Ameribuild can maintain stock in New Zealand for you, and deliver to job sites as needed.
This saves you the hassle of ordering joinery for each job individually and maximises your shipping economy. Ameribuild is the ideal solution for builders of transportable homes, tiny houses, and kitset homes.
