I tried twice to get some, nay any info from our “kin” at breaktime and got zero. I need to put at least 3 awning windows in a basement shop(24’x48′) block foundation wall. The windows are 17×32 the equal to two blocks long and two blocks high, (block is 8×16 +grout and face bricked on the outside). Floor to bottom of joist/house plate is 7’10” and I would remove the 2nd and 3rd block from the top and stay 2 blocks from the corner. Above is a 3br ranch 1.300 sq.ft. with a center beam support pipe every 12′ down the 48′ starting between the two garage doors.
1- is one block above the window sufficient?
2- what kind of header is needed across the opening and how far need it extend past the opening? dual cripple studs on both sides from block row 4 to support the top row(the house) or header?
3- is there a special technique to frame the rough opening to accept an Anderson window, considering weather seal, rain runoff-sill drip curf or metal- ?
4- should the window be mounted and caulked more flush with the inside or outside or centered on the 8″+ brick face wall?
Any info would help as I must start framing out the interior side and need to allow for the windows.
It ammazed me that there was no response as this is not brain surgery for builders who come to Knots and get more good info than they can accomodate.
I have already read every Taunton and other’s books that have the words”BLOCK WALL” printed on any page, to no avail. Thanks, Pat

Paddy,
I wouldn't have any blocks above the window.
Install the windows directly below the sill plate.
Double up your joist header where it runs past the windows; you'll have to shorten the joists to do this.
Run the doubler at least 8 inches past the opening or to the nearest joist beyond.
Use bricks on edge for the sill; slope them for drainage; use the bricks you remove from the wall for the sill; put fabric flashing below the brick sill; let the sill overhang 1 inch minimum.
Install the windows towards the outside rather than the inside; bed them in caulk; shim them with shingles.
The window manuf. should give you the rough opening size needed.
Kid, thanks a million, makes perfect sense to me. Regards, Pat
I should have noted that while I really needed the light, I also wanted the windows as high as I could get them because the soil line falls away from the long back wall. We really don't need folks lookin in at all those fine tool now do we?
I assume sawzall the joists, fit the doubler(2x8 or 10 I think) renail the joists(I will also use hangers) and then cut out the block.pfh

"We really don't need folks lookin in at all those fine tool now do we?"Have you thought about frosted or one-way glass for the lights?Cadiddlehopper
Dear Mr. Hopper, I am lucky to find any awning window under $300, I really don't want to consider special glass. The property falls away sharply on the wall any way. I have been looking for 6 months and found that there are only two sizes in stock, an over size horizontal and a 24 5/8 square by anderson for about $175. The "custom" Home Despot anderson 17x 32 is $182 at last count. I will put two of the 24's in my new barn shed and 4 to 5 of the customs in the shop. The alternatives were the replacement contractors "specials" and there are at least a dozen replacement window plants here on Long Island waiting for a contractor to waltz in with some guy and his princess and quote them a discount price of $380 a window with assuredly a different billing to the contractor. I pressed that issue and the salesman called Big Guido at the plant and got an $80 reduction as they didn't have to field measure. This was for a white foam filled heat welded(poorly with slag sticking up at all the 45 miters) vinyl with a thermal glued pane. I told them " I'll let ya know", and that was the best one.
I didn't think it would be so hard. I was ready to make my own for the shed and buy time for the shop. One wouldn't think that an awning window that keeps out the weather but ventilates would be in such demand or so scarce. It could also be the game to crank up the costs. Best regds. Pat
I was typing too fast and I should state that it's 7'10" inside and 9' 10" outside declining at 2" or more to the foot as you leave the wall. This makes it tough to get a look inside. I was delighted at " The Kids idea to put the windows at the top of the sill plate. thanks again for the concern. pfh

If you go to Anderson's site, they have installation guidelines. Are you using the 200 basement and utility series? The top row of blocks will get loose when you remove the others. They won't actually hold much but you will need some steel to hold them up. 1/2" plate will lie in the mortar joint. The same can be used with the brick and a solder course over. You will be breaking the brick and block back to a joint, so there is plenty of purchase for the steel plate on each side. Generally, the outside face of the window will come about halfway on the brick.
If you use the 200 series, they are 31 5/8" wide or two blocks, and 19 1/4" high. Take out three courses and then build up. This is often worked in with the angle of the sill bricks. You don't have room for any wood on the side with this installation, the widow just fits.
I hope this link doesn't run off the page. You can go to the Anderson site, look up your window and download some installation guides in PDF.

Beat it to fit / Paint it to match
Hammer, thanks , great info, just as I expected at Knots, I will mount the windows in the top tier and be thankfull of my friends on Knots. I have been beating this to death for at least 3 months , now I have answers and can move forward, Pat
Window should be flush with the outside wall. You would'nt want a place for water to gather at the bottom seal. Max 5000 caulk
Kelly, much thanks, Padraig I see the wisdom.
