Secondhand windows

[Crofter]

Looking to do a low budget build, some years in the future, and I was wondering about picking up some good quality windows on Gumtree etc. There seems to be quite a lot of stuff around, I don't know if it's from renovations, or wrong sizes being ordered etc. 

 

Question is, would I need some sort of certification to satisfy BCO about u values etc? If so, what would they be looking for, and would it be stamped on the frame or would I be needing documentation?

Not sure BCO will give a monkeys. If the SAP report says you pass go, you are good to go. It's what the SAP assessor wants really. Mine wanted manufacturers calculations for U value for the whole window.

Probably depends on the inspector.  One thing they may well check (and you do want to get right!) is whether safety glazing is used where it's required. That should be marked on the glass.

SAP assessor and BCO will want documentary evidence of window performance including Uw value & G value (and, as above, safety glass where needed for BCO)

If not a available, they do tend to accept therm calculations.

Love this. 

 

Ok,  first thing is if double glazing often the spacer bar will have  a mark and date with the BS code, sometimes the year of manufacture of the unit. So you can bench mark that with the historic U value of the unit.

 

If you can find that then we might explore more.

It's hypothetical at the moment- was just wondering if I might be wasting my time going hunting for windows on Gumtree.

Why would anyone sell good spec functioning windows?  You may get a few one-off mis measures but not a house worth.

 

Another option could be new housing that has been condemned e.g. substandard mortar or foundations and the houses get binned and rebuilt.

You'd be surprised.

Internorm for example offer a purenit transport bead on their windows, I've known suppliers to not add it, making the window full height and nowhere for the window cill to be added, meaning the opening needs increased or new window. If all windows are the same, they all are wrong and need the opening amended or the whole order reordered (it's happened). Tiny little mistakes can ruin an entire order and expensive to rectify, whether building or order related.

First hit on Gumtree:

(IMHO it's a ugly thing but you get the idea- people make mistakes).

This is actually a more useful link- a whole set of windows and much more local to me. Shame I'm not actually looking to buy yet 😂

Could anybody tell me if the stickers on these indicate enough information for me to satisfy SAP/BCO?
