Reply To: Double Glazing – Retrofits

[Heidi Mardon]

I don’t know of any guidelines that help in decison-making about double glazing; a friend is asking me these questions at the moment as she is trying to decide should she rip her existing windows out and double glaze, get retro-fitted DG or just spend more money on heating…… The Guideline series that BRANZ is developing at the moment could be a good format for a suit of decision-making tools – each subject is about 4 pages with the following concise info:

1. overview, what is [the system in question], how does it work?

2. case study findings from the system installed,

3. computer modeling results

4. questions for homeowners and designers to answer

5. checklist – minimum criteria for installing the system
