Glazing - Getting what i've paid for!

Hi all

been having teething problems with a conservatory company and upon asking them to confirm the glass they will be installing for all glazing other than the roof they replied it would be:

The glazing in the frames will toughened 28mm sealed units made up of 4mm/20mm black spacer/ 4mm low e/ argon filled.

on the spec they gave us they stated it would be:
all glass was to be 28mm with l/e Pilkington KS glass to internal pane and pilkington opti-white externally - all - argon filled with warm edge spacer bars.

I know very little about glazing so I am wondering if a) the two specs match up ( i can already see the spacer bars are different colours (not that i know what a spacer bar is!) and b) how can i check/ensure that the written spec they gave me is what they actually install.

Any advice please

It won't make much difference it'll still be cold in the winter and boiling in the summer. I'd worry more about the installation quality rather than the components quality.

what sort of thing do i look for in installation quality?

That's a bit harsh seeing as you don't know the spec,orientation, size or anything about this conservatory. Someone has paid a lot of money for it and just wants advice.

The glass spec is just about the same. It'll depend on who supplies the glass, as different companies can achieve the same energy rating in different ways, like a car companies make different engines but achieve the same performance.

Spacer bars were always a weak spot for cold transference. Warm edge spacers are made from a material that will stop that from happening, they are usually black, not always though.

If you've spoken to a salesman, they will be vague because they have little knowledge about the product mechanics. Talk to the owner of the company for reassurance, if they are vague that's when alarm bells should ring.

Build quality is important but you should have already done your homework on this and gone for a company with good references.

You can use a heater in the winter for heating your conservatory but I wouldn't think you'd really want to spend that much time out there during the winter, likewise in the summer when you'll spend your time in the garden and use the conservatory in the evening to relax.
