Secondary Glazing |
|---|
| message from Dalesgate on 12 May 2004 |
I have just had a quote for secondary glazing a traditional 1930s curved
5-section bay window., with 2 top openers and 3 bottom openers, and the
estimate was £1750. This is almost as much as double glazing (i.e. complete
replacement) of the same window.
Is this typical, as I thought secondary glazing was supposed to be a cheap
alternative?
What are the typical cost savings compared to double glazing?
Also, can anyone recommend a good (cheap) installer of secondary glazing in
the East Midlands area?

Piggy Back Glazing using clear acrylic sheeting is a good way to install extra thermal
protection and noise reduction to single glazed windows. In fact Screwfix sell a pack
of six sheets of 4mm thick by 1220mm by 915mm sizes for::: Here's a link to tell you
more about the sheeting:

The acrylic can be sawn to the size of the window panel and drilled and sealed to
either the inside or outside of the old windows to create a decent gap to improve the
properties of the heat loss and noise ingress.

Doesn't matter how much or how little it is you don't want secondary
glazing. Yes it is an improvement over single glazing but has some
serious problems.
It makes it difficult to open the real windows. Condensation will be a
problem in the gap, and with a traditional timber window frame this
will lead to rot from the inside out. Yes, you can proabably put
silica gel absorbers in the gap but they will need regular removal and
drying out.
Have you thought about putting sealed units into the existing frames?
OK you won't get 20mm gap units in but even 4 or 6mm makes a
considerable difference. (Wonder if building regs allow this?)

Any idea of cost (parts & fitting)?
Top panes are 430 x 230mm (x5) and bottom panes are 430 x 900mm (x5)...

Not really but sealed units are not expensive. Tracking down a decent
local maker might be harder, follow all the usual stuff, in business
for 5 to 10 years plus, recomendation, see the previous work etc etc.

Does anyone have suggestions for places to get
secondary glazing frames?
I've put in Polycell secondary glazing
in a large number of sash windows,
and have been extremely pleased with the result.
Unfortunately Polycell seem to have ceased to make these units,
so I am looking for an alternative.
I remember Which magazine did a survey some years ago,
but unfortunately I no longer have that copy.
I vaguely recall that Sellotape and Polycell
were considered joint best,
but it may well not have been Sellotape.
Any suggestions or information gratefully received.
