Flat pack timber windows

You don't need paperwork to back up use of timber windows. The u-value of timber is known, as is that of various glazing and coatings.

Sometimes you might need the unit filled with argon instead of air, other times not.


U value of timber is known and variuos glazing etc.... think you'll find you will need documentary evidence to conform to building regs .... ( as you would with Pvc too , that also has ' known ' U values...)

As for Argon Gas ...since the invention of Window energy ratings....ALL sealed units in new frames in a domestic property MUST have Argon and Low e glass at the very least

Seriously guys the thermal ratings are the easy bit. I'm only a fitting company so really you need someone from a fabricating company here but just a few to start are:
PAS24 security ratings
CE marking

I'm on a stag do at the moment and thats just 2 that spring to mind while I'm drunk!
I'm not saying timber windows are a problem (although modern timber is rubbish IMHO) it the self assembled that I cant see passing any modern regulations.
I cant even buy windows from one company and glass from another unless I pay £350 per year for a license to do that.
 
Well on paper the idea of self assembly windows is fine but can see issues arising when the DIYer begins assembly and there's a problem, is it a dodgy kit or an inexperienced DIYer? As for getting a BCO to sign it off I think will come down to the inspector, some will not entertain the very idea others will be happy if it is obvious the windows are well made, let's assume nobody's gonna seriously attempt to make their own sealed units. The Building Regulations documents are actually just one way of complying, BC can take a view on things like this sometimes.

Where are you getting your information from?

The regulations state a u-value for windows. That's all. They do not state with what all units need to be filled, nor that they need a particular coating.

You don't need any documents for any frame either. Whether you buy them assembled or make them yourself.

Sorry but I was under the impression that the regulations stated all windows had to be tested as a whole unit and not a pick and mix deal to give the U value
Or have all the major window companies that manufacture and sell Windows and doors that have had to and continue to provide calculations at extortionate costs got it wrong

Or are we ignoring Part L

If Building Control see fit, they can approve what they like, just because it's written in part L does not necessarily make it mandatory.

I am getting my information from being a member of Certass and Thermal Ratings Register .... may I ask where you are getting yours from?

But if thats the case , what is the point of Building regs , and also Trade'Competent persons schemes'?
 
In cases such as this for example, when some clown of a DIYer wants to fit some terrible old windows he's got for free off eBay, the Regs give the power to BC to prevent their installation, but if the windows seem ok then they can accept them. There is still scope in the Regs for common sense.

So ....

Certass and Fensa companies are being penalised by having to put windows of a certain u value in and average Joe public can put in what they like and BC will sign it off providing they look ok? Think Certass and Fensa ( and their members ) might be interested in that one!

Why are they being penalised. If you want, theoretically, a hassle free supply & installation and sign off to satisfy the numpty solicitors when you conme to sell you can use a fensa supplier/fitter. Or if you want you can pay BC the big fat fee they demand and get your approval that way, with (sometimes) a bit of flexibilty thrown in. Really don't understand why you've got a bee in your bonnet about this.

Who said Joe Public can put in what they like? what was said was that BC can take a view on things.

I've got a bee in my bonnet , because we pay hundreds of pounds a year to be able to self certify our window installations, that HAVE to conform to building regs, to be told that some BC's will be flexible and allow windows to be fitted that are possibly below the minimum level we have to fit. Is that fair? Does that not make a mockery of the 'competent person schemes'?

As for the OP , my suggestion would be to ask his local building control ( and get it in writing too...)
 
No it doesn't make a mockery of the CPS at all. Not everyone wants windows off the shelf. Deal with it! For every good window fitter there's a crap one. Fensa and CPS! Pfffft!
