Are there any options to double-glazing?

The benefit of assessing a project through a NatHERS thermal assessment,is that glazing performance is considered together with all other building elements. A Do It Yourself (DIY) Assessment, requires glazing to be independently assessed from the other building elements and in most cases requires improvement to glazing. Using an accredited NaTHERS assessor and approved software, the project can be improved in more cost effective ways before double glazing needs to be considered. This can result in thousands of dollars being saved.
