Don’t take a risk with Non-Compliant Windows and Doors
Today’s windows and doors have to meet not only design needs but a myriad of performance requirements relating to standards and regulations.
Following is a simple checklist that covers common issues involving window and door compliance.
- Correct wind loads for the site and construction type. There are 3 different construction types: Housing, Residential and Commercial. The wind load requirements determine the windows and doors needed for the project.
- To help reduce the incidences of small children falling from windows, window restriction and screening are now mandatory in certain applications. The key factors to keep in mind are the size and height of the opening and the existence of foothold that can be used for climbing.
- Selected windows and doors comply with thermal comfort requirements. Ensure that the supplier match or exceed the required U value and Solar Heat Gain Co-efficient with their WERS rated products.
- Many construction sites now fall within bushfire-prone areas. It is important that windows and doors comply with the required bushfire attack level (BAL) as stipulated in AS3959.
- Houses and buildings located in a transport noise corridor must comply with minimum acoustic requirements. Selected windows and doors need to match or exceed the required Rw rating. It is important to note that glass only Rw rating is non-compliant.
- The windows and doors must be supplied with performance labels attached to them. This is a requirement in housing and optional in residential & commercial buildings. These labels confirm that the windows and doors are certified to comply with AS2047.
- All suppliers must be able to verify compliance by providing a Certificate of Compliance on request.
The potential for liability as a result of using non-conforming windows and doors is enormous; from a financial perspective and more importantly from a safety standpoint.
