Bump outs are just extra surface area that will conduct heat. There essentially unnecessary. Certainly the designer/architect could have found ways to end up with the same square footage without a bump-out. But then if the customer wanted a bump-out!

Supplying energy to make up a house's heat loss is a deign failure. Design failures are the designer's fault, particularly now when a house's building energy demand can be easily modelled at the design stage.

"Now to find out whether Andy Engel was right when he told me that working with mineral wool was worse than fiberglass..."

Having installed both, I'd prefer the Roxul. It's a little more solid and holds together pretty well.

People's past impressions with mineral wool, which is a pretty old (archaic) term, may not be valid. I recall coming across old mineral wool during renovations and Roxul isn't the same stuff.

The big box stores and lumberyards up here in the region around Canada's national capital (Ottawa-Gatineau) only stock the residential batts too.

The kind of Roxul products you are looking for are more likely to be found, around here anyway, at suppliers who sell to contractors working on the commercial side of the business; those suppliers who sell to contractors doing flat roofs or apartments and office buildings. It may still be a special order, but it might be a special order from another location of that supplier. And they tend to ship back and forth between locations pretty regularly. I can think of Convoy Supply and Givesco in Ontario and Quebec as two options though that won't help you down your way.

Hi Kevin,

You have the wrong URL for Thermotech...

http://www.thermotechfiberglass.com/

Thermotech Fibreglass the window manufacturer and Thermotech Windows the window sales and installation company aren't the same company. They kind of once were... you'll have to ask Stephen Thwaite about that history. It does seem to create some confusion.!

They are indeed very good windows. I have a bunch in my house, alas they aren't all Thermotech's. I wish they were!

Cheers,

Andrew

Is it a house or a convention centre?

Either way it will never be a home!

Can't seem to find a way to contact you directly so I'll try via a comment. I guess in a way it has to do with something to do with adding value to your house, intrinsic value. A few years back FHB had a piece highlighting the work FHB staff members did on their own homes, the small cool projects. One of the projects was a window seat that had a shelf that pulled out so that a person reclining could set a mug down without having to put it on the floor. My wife would love to see a picture of that window seat again, as we have one in our plans. I tried searching, no luck... asked for help on Breaktime, and a member there thought that it was your window seat. Any chance you could send me a picture of "your" (?) window seat? Or the issue number.

Thanks for your help.
