Regulatory requirements for Windows: Northern Ireland - A summary of the requirements (Version 1)

TRADA image

The number of regulatory requirements placed on windows has grown considerably in the last 50 years. At first take one might think that a window is only required to let in the light, provide fresh air when required and keep out the weather. As the following sections show, this is certainly not the case.

As part of our revision of the TRADA publication Wood windows: designing for high performance, a review was undertaken of the main regulatory (and some code-related) requirements for windows. This Construction Briefing has been designed to summarise the results of this exercise in tabular form for ease of reference. Over half of the Technical Booklets for Northern Ireland have some impact on window design, so this summary is likely to change quite frequently in the future.

Wood Windows: designing for high performance provides detailed guidance on how to design to windows to achieve these requirements and therefore the two publications are complementary.
