Secondary glazing

FreddieFrugal

Hello, has anyone had experience of ordering/purchasing secondary glazing units?
I'm trying to get an idea of costs for comparison and also looking for recommendations for good companies.

We want to get a secondary glazing window to install within the existing window recess to reduce noise penetration from outside.

I found Duration Windows which have various specifications of secondary glazing units and actually provide easy online quotes, had quote of £250 inc vat for a unit with a fixed panel in the centre and two horizontal sliding panels either side to get access to the main window. (4mm glass)

£297 with 6.4mm laminated glass

I put in a rough estimate of window size as about 1m x 1.6m

I have found that they look cheap and tacky, Probably be better off looking at replacing the window instead for a decent one.

It's going behind a double glazed window.
The look isn't important to be honest. It would be behind a large wooden Venetian blind, mostly obscured from vision and it's in the main bedroom at the rear of the house.

The idea behind it is to try and reduce noise (specifically from next door when they're in the garden late at night which they seem to be every day)
I believe that having a secondary barrier with a gap will provide a much better sound barrier than a single window can achieve on its own.

I doubt you will notice a great deal of difference really, A bit but not what you could be hoping for if it is quite noisy.

Secondary glazing seems to be the recommended solution for reducing noise.
You might consider replacing the rubber seals around the windows 1st though. Over time, they turn brittle and you loose the air tight seal.

Secondary glazing is a good option for noise reduction. Most DG is rubbish at noise reduction (ok it's better than single glazing).
If fitted property secondary glazing will give you great noise reduction.
Cost depends on the type of unit, you can get all sorts of sliding, folding or manual fit on/off.

The problem is, it's quite specialist. The big names don't do it so you need to look for local firms who do all sorts of glazing.

With a 4" gap SG is very good. Freddie I know a company but only in Birmingham, no idea where you are. They can also upgrade your existing DG units to triple which helps even more.

Have you considered triple glazing? This is getting more popular now as the double glazed unit can be replaced with a triple glazed unit quickly, with no disturbance to any decorating. Whole job can be done in a morning on most houses.

I use to be a rep for Everest, and i got secondaries. Most of the reps bought them for their own houses so long the main frames were ok. When the origional windows started to rot 20yrs later and needed replacing i kept some of the new replacements to the same design and refitted the secondaries giving me triple glazing.

For it to be quite effective it would have to be 3 diff sizes. I have 6.4 outer, 4 middle and 6 inside.

A standard 4:4:4 triple unit only helps a little

Secondary glazing is something else providing it's at least 100mm away from the existing window.

Fair enough, it was just a thought. You have obviously researched the problem.
