It’s no longer business as usual for skylights

The next important factor to consider is the window size (or aspect ratio) as this also has an impact on the construction R-value of a skylight as a building element. Normally the thermal resistances of the glazing and the frames are dissimilar. For large windows, the thermal resistance of the glazing will have more impact on the overall window construction R-value than in a small window, which is dominated by the frame performance. This means that the construction R-values of two differently sized windows consisting of identical frame and glazing materials will be different.

With the above in mind this therefore rules out the possibility of using a generic skylight R Value in compliance documentation and means each skylight will have to have its Construction R Value calculated separately.

This may all sound rather daunting as it differs from the way we have done things in the past, however Adlux are here to help. All you need to do is send your plans to sales@adlux.co.nz and provide us with is the following information and we will be able to produce a skylight construction report for your project.

–              The overall size for each skylight

–              The pitch of each

–              Building Consent Number (if known)

–              The project name or address

It is also important to note that whilst there is no minimum R Value requirement in H1/As1 for windows, doors or skylights unless the Scheduled Method is being used as the pathway for compliance, Adlux is working hard to bring you the best performance possible across our range of products.
