Expect the T1-11 Siding prices to fluctuate between various companies – each and every company have different operation expenses and over-head. You can get Plytanium 4×8 feet panels for as little as $23, although it will also cost some money to get a pro to install it if you’re not going to be doing it yourself. This sheet of T1-11 siding costs $33 per sheet. Being 48 inches by 96 inches, that equates to the common 4×8 feet, meaning it has a total square footage of 32 square feet.

Robert asked

I want to build a shed using vinyl windows with T-111 siding. There is no other sheathing under the siding so how should I frame the window openings so the windows don’t leak and how do I cover up the nailing flange on the windows

Robert,

There are several methods of installing vinyl windows with T-111 siding. One of the simplest and most maintenance free methods is to utilize vinyl brick mold to seal and

vinyl window without J-channel

cover the nail flange. I recommend using vinyl windows that do not have built in J-channel. If it does have a built in J-channel extra care must be exercised to ensure a good seal between the J-channel and the vinyl brick molding.

Frame window opening to the rough opening size recommended by the window manufacturer
Install T-111 siding with window openings cut out to the same size as framing
Wrap jamb with plastic vapor barrier that covers framing and extends about 3 or 4 inches onto the t-111
Apply a liberal bead of caulk on the window wrap all the way around the window opening
Set the window in the opening ensuring that the caulking seals the window flange to the wrap on all sides and nail the window in place
Apply a continuous bead of caulk on the face of the nailing flange centered over the nails/nail slots and another bead on the adjacent side of the window jamb
Cover the nailing flange by installing vinyl brick molding around all four sides of the vinyl window in a “picture frame” configuration
Use PVC glue or adhesive caulking on the corner miters to prevent water infiltration
Caulk the exterior of the brick mold to seal it to the siding/window wrap with special emphasis on the top
For increased weather protection install a metal or vinyl drip cap over the window

This method will make the window installation watertight, mostly maintenance free and allow for replacement of the window if needed without having to disrupt the siding. Routine maintenance such as caulking and painting will extend the life of the shed indefinitely.

T1-11 is made for outside, like you said. It will gas off formaldehyde & all kinds of other nasties you really don't want to be breathing. It probably also has insecticide built into it as well. I can think of 100 reasons not to use it indoors, but not one to actually use it.

Also asked, how long does t1 11 siding last?

This is all part of What Makes a Quality Paint Job. We believe it will last far better than T1-11 siding, and should last about 20 years before it needs its first repainting.

Secondly, what sizes does t1 11 come in? Description. T1-11 plywood sheets are available in 48-by-96-inch or 48-by-120-inch sheets. Sheet thickness is either 3/8, 5/8 or 3/4 inch. T1-11 is available with a rough-surfaced, textured finish or a smooth, sanded finish.

Also to know, can't 111 siding be installed horizontally?

Originally, T-1-11 siding was made from standard A-C plywood with a “textured” face ply (thus the T symbol in its name) and grooves cut into the plywood along the 8' length. Installing the siding with the grooves vertical or horizontal doesn't matter with the inner plies plugged. Moisture cannot enter the siding.

Do you need to prime t1 11 siding?

Prime the siding with a heavy acrylic primer. I've used XIM Peel Bond with great success. Because of its finish, painting T1-11 siding is rather tricky. Use a roller for large areas, and a brush to get into grooves, and tight spots.
