How to specify high performance windows
These product performance elements need expert specification as it is critical that the windows are in full compliance with building regulations which are often complex.
Some glaziers with low performing windows will quote the Ug value as the overall U value to deceive customers into thinking the system is more insulated than it is. This means it is important to make a distinction between the Uw and Ug value to ensure you know what ‘U Value’ your glazier is quoting.
As experts in glazing, Sieger® can supply up to date data on all of our aluminium windows regarding these specifications. Information such as thermal insulation, weather protection, security and pictures can all be found on our product pages and on the downloadable product sheets.
To assist architects with NBS specifications Sieger® have created individual NBS specification sheets for each Sieger® system product. These documents contain all the vital information needed for specification. If you would like one of our draft NBS specifications just ask your sales contact at Sieger®.
