This came from another post, and could be proven wrong, but although the average commercial job for me is way larger than any residential I have, my round is 90% residential.

My question is if we counted every pain of glass in the country on residential properties and did the same with commercial properties, which total would be greater?

More panes of glass for residential but not in square metres

Major window cleaning contractors do not carry out residential window cleaning.
Their are thousands of establisments that have teams of static window cleaners working just on them month in month out.
If you forget about the exterior glass just think about all the internal glass partitions,lifts, escalators, curtain walls etc on each and every floor of any type of commercial building.

Still think its resi, but might be close. This isn't a go at you though, you seem adamant is comi, and I think resi, so would be interested to see what everyone thinks.

From the 2001 cencus

There are a total of 22,539,000 households in England and Wales

The average number of rooms per household is 5.34.

that's 120,358,260 windows if there is one in every room and thats just England and Wales.

The population of the United Kingdom grew steadily over the last decade of the 20th Century to stand at 58,789,194 on Census Day 2001.

I guess I am going to have to find the sqm of glass intalled into commercial premises now

Does a farm count as residential or commercial?

What about all the trains,buses,coaches ?
