Double Glazing Units - Failure ??

Recommended Posts

Anyone in the window trade happen to know if it's usual for the standard double glazing units to fail after 10 years?

As far as I know these were not premium like Everest ones and I know little about who made them.

This house was a new build 10 years ago, so far I've had 5 units fail.  Whilst they're easy to replace, far easier than traditional glazing, it strikes me it's a not very long time for them to begin to fail

Would failure be covered by the NHBC warranty, for that matter?

If they were fitted by a lower class company then a failed unit is not uncommon.

Most warranties don't go past 5 years tbh unless from a major company.

It's termed in the trade as 'cheap and nasty - cold and draughty'.

I did a 3 month stint with a company while waiting for my military joining date many moons ago and you'd be amazed at just how much profit those companies make.

Once a sealed unit leaks there's no point resealing them as you'll never get rid of dust and moisture between the layers.

There are loads of companies that do replacement units and shouldn't be too pricey.

My flat is only about 12 years old and all the windows are failing!  Not only the seals but one frame is loose from the wall (slightly worrying!), the French doors can't handle wind and there's a huge gap between one window and it's frame.  I've done my best with the draught proofing for now lol.  I don't expect they were quality windows when fitted but also thought they should last a bit longer myself!

Double glazing is old school now anyway, saw an ad on TV for triple glazing the other day...  Now I'm wondering where we'll be in a few years time...12" thick octuple glazing maybe? :laugh:

Thanks Clive:smile:

That'll be them "cheap and nasty - cold and draughty" 

So, failing after 10 years: I've had exceptional use from them.:cool:

The developer seemed to specialise in in cheap and nasty except, bizarrely, for the sanitary ware.  But even that might be factory seconds or thirds.  If you ever want to see "how not to lay a pavior drive - I have one, a testament to appalling workmanship and incompetence:huh:

A good double glazed window can easily last 25+ years, so I'd have a word with either the company their from (should be printed somewhere between the two pains), the company who fitted them or NHBC like you said.

I agree with that, I know of cheap council double glazing that's now 15-20 years old that's never had any issues since it was installed. 

We have had a couple units fail on our house which are now 10-12 years old but they were cheap units. 

The glazing unit itself is simple to swap over and shim. We have replaced our faulty units with argon filled ones - whether you notice any difference or not I can't say I've noticed.
