Sizes

Maximum sizes for bay and greenhouse windows and sashes vary by width, height, wind zone, and glazing requirement. Your local Bradnam's branch will be able to advise you whether a configuration is possible or contact Altus Technical support.

As a guide, fixed window panels up to 1.2m high by 1.2m wide are attainable. Normal configurations involve multiple mullions and transoms that can be used in combination to meet most requirements. Limitations often relate to the structural nature of the support for the window, i.e. how much weight they can they hold.

Note: For compliance with NZS4211:2008 and or the NZ Building Code a security stay, safety latch, or restrictor may be required for certain sash sizes.
