Sounds bloody expensive to me whatever sort you get. No wonder there are so
many door to door sellers of double glazing.

Actually - if you can afford and get good people, subcontract. It gets
depressing as it drags out.

Our slowness was due to lack of dosh. That problem has reduced and I have
happily got some help on certain areas, whilst being lucky enough to
maintain the original design ideas.


Q1. The existing windows are narrow spacing double glazed in brown
painted pine. Two or three panels are blown and need renewing anyway. My
first thought was to strip out the glass and strip off the paint.
Re-paint in white and fit modern argon filled panels. However, the
glazing rebate is much too narrow to use 4:16:4 units.

Six new windows are required for the alterations so current thinking is
to go for new throughout. First estimate for 12 windows and two doors
came in at 18K fitted. This afternoon was spent trawling round the local
showrooms. I'm not much wiser:-( The much vaunted narrow mullion
aluminium does not seem to exist. By the time they have put in the
plastic thermal break and endless folds for strength and appearance they
are as fat as uPVC.

If you look at windowsanddoors.co.uk you will get an idea of the cost of
the units - at least for uPVC


Also, what happened to window hinges and stays? They all seem to use a
fancy sliding meccano mechanism which relies on a tiny strip of plastic
in a groove to retain the window against a stiff breeze.

I know what you mean. Not as bad as they look - and hinge bolts mitigate.
I recommend you specify egress (corner swinging) hinges - they always seem
to default to "easy clean" which I hate.

And why do doors supplied by such outlets have such flimsy threshold
strips?

You can get uPVC with a low profile ali threshold - I have one. And you
can bond or seal that down whereby it is pretty solid.

Also, also my wife who is somewhat challenged vertically came back from
a jaunt to the Cotswolds determined that fanlights are out! (hard to
clean and hard to reach). The new *in* is top hung bottom latched full
length openers.

Thoughts please. Does uPVC really stay clean and shiny for 20 years?

Non white might.


Are these fancy sliding fixings reliable?

Yes, IME.

Can a bottom opening style meet the fire escape regulations.


Pass.

Why not go for full height casement with egress hinges? (and egress hinges
often have an "easy clean" mode).
