Key Learning outcomes
- The practical impact of a low thermal performance target (U-Value).
- Understanding the measure of solar gain and how it can impact on design.
- Understanding acoustic terminology and how it can impact on design.
- How each of the above can conflict with the architectural intent.
So, a window. It’s easy? A hole in the wall in which the occupants can see out of, whilst allowing light into the building and providing protection from the elements. Unfortunately, not.
Window specification can be complex, there is more to it than just keeping the cold out and the warmth in. We need to consider the levels of light required in a room, the need to create a safe and secure environment, all whilst protecting against the Earth’s natural elements and other man-made factors such as noise pollution.
There are many aspects of window specification that we are asked about as a window manufacturer, however three of the most common criteria that we are asked to comment on are: Thermal Performance, Solar Control and Acoustic Performance, as such we will focus on these throughout this article.
This article will identify how we finalise the specification of a window system, considering building regulations but also the additional requirements of third parties such as M&E consultants, acousticians or employers requirements, all of which can influence the overall design and cost of your building.
