Wild West Window Installation – How To Install A Vinyl Window
Now you might believe you understand how to put in a window. Odds are… you do not. You may be asking yourself”Why would this guy know more than I do?” . Trust me, many installers who’ve been installing windows for 20 years don’t have any clue the way to correctly put in a window. Yeah right! What makes you an expert? Well to Begin with I’m a Certified Window Installer. I had been until a Couple of months past that the Inspector for the Siding and Window Dealers Association of Canada at Calgary. I had been frequently known as”the Association’s best inspector” I do not know whether this was accurate, but I discovered it several times. The reason why I left the institution was that I was miserable that the Association wouldn’t impose their own rules, which makes my job useless. I began building homes in 1982 and have assembled all of the doors and windows in my house from walnut. I understand windows.
Producers offer windows with nailing fins. These nailing fins are generally utilized to hold the window in position with no other support. As I have explained in a former article, this isn’t right. There is a really important record titled CSA A440.4-07. Here is the right way of installing a window. Now, it is 114 pages long and I’m not likely to attempt and cover everything in this report. Can it be required from the Building Code? Yes, at least in Alberta and I guess everywhere else in Canada. Article 220.127.116.11. Environmental Separation of the Alberta Code lists this CSA Standard. The Standard itself says it is supplementary to some Manufacturers’ Installation Instructions. That means that whatever the manufacturers’ directions are, you still need to abide by this Standard. Are Installers complying with the Standard? No. I guess that over 90 percent of those windows installed don’t comply with the Standard. Including new houses and renovations. Therefore, in the event that you’ve only had windows installed, then odds are they’re installed incorrect. If the chances were good in Vegas, my money could be on the desk.
“My widows work fine! They look great and the Installer cleaned up nicely when he was done. What’s the difference?” The distinction is durability. In the event that you should place new windows in your home the bill would likely exceed $10,000. 00, bigger houses are . How long do you prefer those windows to continue? If the window isn’t supported correctly, the window will melt and change. Most windows nowadays are made from vinyl, so the vinyl is only going to take as much stress. Since the window , the framework will crack, or even the glass can break. Lately, I scrutinized a new residence. I started a casement window and discovered that I couldn’t close it. The framework had sagged along with the window no more match the framework. This was brand new! I believed the window may be re-installed, however after speaking to the Manufacturer’s Rep. I discovered that the window couldn’t be salvaged and might need to be substituted. The Manufacturer was providing the window totally free of charge into the Builder, since they did not need to eliminate the Builder for a customer. If widows aren’t installed correctly they’ll fail , how badly depends on how badly they have been installed.
As I mentioned previously, I can not expect to offer you everything from the 114 page document that’s CSA A440.4-07. I will attempt and narrow it down. Many widows are plastic, many windows are sliders and many window replacements are full tear workouts rather than installed within the old framework. This is supposed to be pretty manageable. You will find differences with various materials and forms of window, and thus don’t attempt to extrapolate.
Step 1: Ordering Your Windows
Take the casings (moldings) enclosing the windows. If you feel that can assess the window without even taking off the casing, you’re mistaken. You don’t have any clue what the former installer did. The present window might be too big and can be pressured in or too little. I know of a young renovator who got stuck with the job of installing windows which his father ordered. Dad did not measure very nicely and all of the windows were too large for its rough openings. He could not return . If it was not his daddy he could have said no. The notion of the project makes me cringe. Measure the diagonals and be certain that the rough opening is square. You desire the new windows to be roughly 1 inch smaller in both dimensions than the opening. That will provide you around 1/2″ all around the window for shims. If the openings are not square, as determined by measuring the diagonals, you might want to make the windows a little smaller, because you want the window square. The supplier will want to know if the wall is 2×6 or 2×4. You’ll also want to decide if you want a “brick molding” or not on the exterior. You’ll have to figure out how big the brick molding should be and compare that to what is available from the manufacturer, and adjust from there. If you want my opinion order the windows without a nailing fin. For more information click custom window installation nyc
Step 2: Removal of the Old Windows
Once the new windows arrive, inspect them. First check the new windows and make sure there is no damage and that they are the right size. You don’t want to find that out once you’ve removed the old window.
The idea here is to remove the old windows with as little damage to the house as possible. That means you have to put the sledge hammer away. Cut any caulking, that way it won’t be a problem, and it can be a problem. If you can find fasteners, remove them. Sometimes there are nails through the brick molding or screws through the frame or nails in the nailing fin. You’ll only find the nailing fin if you remove the trim or siding around the window. If you are dealing with stucco or synthetic stucco and there is no trim around the window, cut the fin off and leave the fin there. Once you’ve removed all the fasteners you can find, it’s time to remove the old window. Again, no sledge hammer. The window will probably be difficult to move, but it should be loose everywhere. You can use a hacksaw blade to run around the window, there may be some fasteners that you were not able to find. You can use a reciprocating saw to cut any fasteners in the gap, but do it gently. Remove the sashes (operating windows) and try to remove the fixed panes without breaking them. I usually use a small pry bar with a wide blade. If the window won’t just slide out with some gentle tapping, I usually cut through the bottom of the frame around the middle and pry the two halves up. I can usually remove the other frame pieces easily from there. Try to put as little stress on the building as possible.
Step 3: Cleanup & Preparing the Hole
At this point you want to examine the framing around the window opening. Any wood that is rotted should be replaced. That’s easy to say. It’s sometimes tricky to remove the wood, replace it and keep the strength of the structure intact. If there is just some mould, spray it down with some bleach and move on. The building paper probably got mangled when you were removing the window. Trim it back and repaper as best you can. The purpose is to protect the wood. You can use a peel and stick product, it works really well. You are limited though, because in some cases the siding is still in place. Remember that higher pieces overlap lower pieces. Water runs downhill… usually. Start at the bottom and work your way up. There are lots of diagrams to show you how to get this right. The bottom sill piece is made longer than the hole and cut so that it folds up the sides of the hole, and hopefully there’s a little room below the hole so the piece can fold onto the exterior sheathing and run past the hole on either side. The side pieces should be cut so they fold onto the bottom of the hole and fold onto the sheathing. The extension of this piece should overlap the bottom piece. The top piece is a little trickier. It should tuck under the paper above the window if possible and be cut and folded as the other pieces. The point is to restrict water entry and protect the wood framing. There is a good diagram available on the internet.
Step 4: Installing the Window
Place two sets of shims about a 1/2 inch thick on the rough sill and check for level. I say two sets because shims should be used in pairs, assuming that the framing is relatively straight, and it often isn’t. Rough sills are rarely level and you will have to adjust your shims to get a level surface to rest the window on. While someone holds the window in place for you, get the bottom frame member of the window level. Drill holes through the side frame pieces about eight inches down from the top of the window and run screws in to hold it in place, not tight. Alternatively, you can drive nails in on each side of the window. You’re just trying to stop it from falling out while you are working on it.
You will have to add shims at strategic points under the bottom frame member. These shims are critical to the durability of the window. Without them the window will sag. You need a shim set under each vertical member of the window. You will also need a shim set under the quarter points of any fixed pane unit. Measure the width of the fixed pane, let’s say it is 24″ wide. Divide by 4, which provides us “. Measure that distance in from each end. You need shims there. You’re probably wondering why. The manufacturer supports the glass in the frame at those points. If there is no shim under it, the weight of the glass will warp the frame downward at those points. I’ve seen it many times. Once these points are taken care of, check to see if there is more than 16″ between some of those shims. Install extra shims as required to decrease the spacing to 16” or less. Make sure the bottom is level.
On a slider you can just about put your level away at this point. If the bottom is level, it’s just a matter of making the window fit properly. Open the window, just a bit so you have a very small space between the sash and the frame. Use shims to adjust the frame until that space is even from top to bottom. Work from the bottom up. First shim set goes at 8 inches up. Now the Standard says you don’t have to fasten the shim in place. If you don’t the shim becomes useless once the insulation is installed. The frame will bow in. If you run a screw through the shim as is suggested but not required in the Standard, the window frame is trapped between the screw head and the shim. It’s not going anywhere. Shim sets (and screws) should be placed every 24″ up the side of the window along with 8″ from the top. You’re probably wondering why 8″ in the top and 8″ from the bottom.
Vinyl expands with heat. If we put the shim too close to the corner. The vinyl expanding sideways will have nowhere to go. It will either bow or break. We don’t want either one to happen. When the shim is 8″ in the corner, then the vinyl can enlarge along with the shim is close enough to coax back the window to the original place once it cools. There aren’t any shims at the surface of the window, unless it is a major window and it’s sagging. As soon as you’re delighted with the setup, cut on your shims off marginally back from flush on the inside as well as out.
Step 5: Insulating
Use polyurethane expanding foam which expands a bit. Leave the 3X expanding foam onto the shelf. Install the foam . If you use a lot of foam you will distort the window pushing the framework . You can see why, in case you have not employed any screws to secure the shims in place, the shims become unworthy. Use the minimum quantity of material. Start with a coating in the outside, about a half inch deep and broad enough when enlarged to fill the gap between the window and the construction paper you installed before. When there’s a brick molding installed, then you’ll need to put in this from the interior. Then do the same on the interior. You want the foam to bulge out a bit and also contact the vapour barrier. At this point you have two layers of insulation along with also a dead air space between them and also a constant vapour barrier. When the foam has installed, trim it off flush with the drywall. The endings of your shims should pretty much flush with the expanding foam at the time and they’ll allow air passing, so caulk the endings of these to seal them onto the inside. Install casings on the inside and caulk the joints. Install casings on the exterior if you do not have brick moldings and caulk there.
There is a good deal of detail I haven’t covered, like kind of screws, measurement I and high quality of shims. Additionally, there are answers to quite a few issues you may encounter on the way. If you are an installer, then you understand exactly what I mean. It is not merely a matter of moving to the building supply store and sticking the chimney in the weekend.
