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.
