Whether you’ve seen it advertised as T1-11 or T-111 siding, this “go-to” familiar siding product is made of wood, giving homes a natural woodgrain appearance. A mainstay when it comes to home construction, it’s easy to work with. Cutting and maneuvering it is simple, making its installation less time-consuming than other siding materials. Its unintimidating nature makes DIY projects both quick and cost-effective.
The problem is that if its high maintenance requirements aren’t strictly followed, it will fail.
What Is T1-11 Siding?
Used for a variety of DIY home construction projects like tool sheds, dog houses, and interior ceilings, and popular in the 1960s through 1980s, this once trendy, cost-effective siding comes in two types: plywood and oriented strand board (OSB). OSB is the more cost-effective option due to its makeup of wood flakes glued and pressed together.
It’s cut into practical panels, often with exterior grooves that make a shiplap or rustic board-and-batten look easy to achieve. It can be painted, stained, cut, and arranged in different ways to create a variety of looks.
If you cover your home with T1-11 siding, and you want to switch up the look of your exterior after a few years, it’s fairly easy with this versatile material.
T1-11 is available in both smooth or rough finishes, and comes in three different thicknesses: 3/8”, 5/8”, and 3/4”.
The Disadvantages of T1-11 Siding
- Moisture intrusion—T1-11 siding may look great, but typically it fails due to moisture damage. When OSB T1-11 gets wet, it swells, expands, and eventually flakes, chips, and rots.
- High maintenance—T1-11 lasts and keeps looking good only if it is well maintained. It needs to be properly installed, painted, stained, and sealed. It must be meticulously tended and kept sealed so it can protect your home from moisture damage. It needs to be stained every 3-5 years.
- Wrong uses—Some homeowners choose to install this siding on their roof and deck, causing problems beginning when it’s installed.
- Absorbent edges—If T1-11 boards come into contact with the ground before installation, its highly absorbent edges may draw in moisture.
- Not eco-friendly—T1-11 adds to the overall carbon footprint of the homes it covers.
- Not fire resistant—The flammability of T1-11 ranks much higher than other siding materials like brick, stone, or fiber cement.
- Easily damaged—This siding tends to rot, warp, corrode, and mold when left untreated. Your home’s curb appeal and value can be negatively impacted as a result.
- Needs frequent repairs—Not only does this siding require high maintenance, but it also has high repair needs. Damage can occur from the weather, woodpeckers, pests, or even fire. If you procrastinate repairing damaged T1-11 siding, additional problems can occur, leaving you with even more to repair. If problems are extensive, siding replacement becomes a better choice than repairs.
- Installation problems—When T1-11 isn’t installed properly, your home may become exposed to additional moisture as gaps or loose panels hinder insulation and produce pockets for dampness to build up—leading to more extensive and costly damage. It should never be installed flush to the ground, as that type of contact may increase moisture buildup in the siding.
