Basics of T1 11 Siding

New Construction-House

T111 or t1 11 siding is among the most durable and long-lasting of contemporary siding options. Conventional wood sidings tend to present a host of problems ranging from moisture seepage to repeated maintenance demands like painting and staining. However, a wood-based siding like t1 11 siding is free from such issues. Further, it is much cheaper than a cedar wood siding but still exudes the same aura of a rustic, stylish siding.

Overview of T1 11 Siding

It should be noted that the use of ‘T111’ is actually a more popular misnomer and has become a mainstream method of referring to t1 11 siding. T1 11 siding is essentially a plywood panel-based siding that is laminated for extra durability. Its external appearance is cleverly manipulated to resemble that of natural wood. This is done by establishing long, vertical strands that resemble natural wood grain found in hardwoods. Most of the t1 11 sidings are retailed with a standard measurement, in the form of sheets. Being wood-based sidings, these sidings can be easily cut and manipulated to cover the demanding roofing edges and corners.

T1 11 Siding History

T1 11 siding first rose to prominence during the late 1960s. It has been in use for more than four decades wherein the core concept and the appearance of the t1 11 siding is still similar to its decades-old format.

T1 11 Siding Grades/Varieties

T1 11 sidings are sold in two, main variations:

  1. Plywood Sidings
  2. OSB sidings (oriented strand board)

Plywood T1 11 & OSB Sidings

OSB sidings are also referred to as waferboard sidings. These are more vulnerable to moisture seepage related issues than plywood sidings. This is because OSB sidings incorporates a greater concentration of natural wooden bits like wooden flakes, cellulose fiber strands and natural resins that make the siding more permeable to moisture.

The plywood variety is a bit more expensive than the OSB siding but it is reputed to have a better finished appearance and resembles natural wood to a greater extent. Plywood t1 11 siding is also referred to as Plywood T1 11 siding and is said to be a very durable option once it is stained or primed in the appropriate manner.

Plywood t1 11 siding is sold with two minor variations whereas the OSB sidings are a standard offering. Plywood t1 11 siding is sold in the hewn and sanded varieties, both of which are surprisingly similar to hardwood sidings.

Issues with T1 11 Siding Installation & Repairs

Please note that t1 11 siding is sold in the untreated form. Unlike natural hardwood sidings, wherein painting or staining isn't always needed, t1 11 sidings need to painted or primed at the time of installation—this is an unavoidable installation and maintenance expense.

Most of the older homes, with aged t1 11 sidings, present a more demanding undersurface at the time of executing repairs or replacement of sidings. This is because the t1 11 sidings were previously installed with bigger, waterproof studs. These studs were hammered much deeper than the present-day installation studs. As a result, at the time of replacing the siding, the roofing insulation or the roofing deck are likely to be damaged.
