What are the best installation techniques for achieving optimal energy efficiency with R21 insulation in 2x4 walls?
The best installation techniques for achieving optimal energy efficiency with R21 insulation in 2x4 walls include ensuring a tight fit without compression, sealing any gaps or air leaks, and using a vapor barrier to prevent moisture buildup. Additionally, installing insulation properly around electrical outlets and other obstructions can help maximize its effectiveness.
What is the cost per sq ft for insulating exterior 2x4 walls 16 on center?

What do you need to build walls for houses?
That depends if it's an interior or exterior wall. Interior walls are basically studs (2x4 pine lumber) covered with drywall ("sheetrock" is a common brand). Exterior walls can use 2x4s or bigger lumber (2x6s), with insulation in between them. The inside part of the wall is covered with drywall, the exterior is usually covered with plywood or OSB sheathing. In some cases, there is simply foam board on the outside. Then that (the plywood/OSB or foam) is covered with some sort of siding material (vinyl, wood, brick, etc).
Can you install cavity wall insulation in timber framed houses?
It all depends on the wall construction. Timber frames can have conventionally framed 2x walls or SIP (structural insulated panel) walls. If the walls are made up of normal 2x4 or 2x6 studs, insulation can be installed or replaced in between the studs. If the walls are SIP's the insulation is already there. To see a typical timber frame SIP wall configuration, see the link below.
What is the wall thickness of a regular house?
Usually interior walls are usually a 2x4 3 1/2 inches thick with 1/2 drywall on each side so they are 4 1/2 inch thick. Exterior walls are a 2x4 3 1/2 inches thick with 1/2 drywall on the interior and then the exterior covering which can vary in thickness depending on type. In countries that use 'mm' as their measurement, exterior wall 270mm (110mm Brick, 50 Cavity, 110mm Brick/Stud Wood Framing) and interior walls 110mm (Brick/Stud Wood Framing).
How do you build walls?
Walls are commonly framed with 2x4 lumber, known as studs. The covering is fastened to the wall to enclose it.
What is the average wall thickness?
5-6" The average wall is a constructed 2x4 stud wall with a layer of Sheetrock on top of that. As can be found on the Internet, a 2x4 is actually 1.5" x 3.5" And a piece of Sheetrock is .75" So .75+.75+3.5= 5" An exterior wall is thicker due to the different materials used in the construction. It is also has a 2x4 stud wall framing with a layer of 3/4" OSB(Oriented Strand Board) or Plywood with a layer of plastic (negligible thickness) and the exterior material on top of that. Other Variations include various foams and insulation layers.
What is the thickness of an interior wall and exterior wall?
In the U.S., in most cases, the framing for both interior and exterior walls is 2x4 dimensional lumber with an actual dimension of 1-1/2 inches x 3-1/2 inches. With 1/2" drywall on both sides, a finished interior wall will be 4-1/2" thick. With drywall on one side, and 1/4-3/4" exterior sheathing on the other side, an exterior wall will vary in thickness. Siding, stucco, or brick veneer will add to the exterior wall's total thickness.

How do you find out how much insulation you will need in your shop that is 8 feet 10 inches tall and 14 feet x 24 feet?
Unfortunately that is not enough information. Is it built with 2x4 walls? 2x6? 2x8? 16 inch on centers? 24 inch on centers? Is there an attic? Trusses, flat roof with 2x10 rafters? If there is an attic you will be well insulated if you use blown-in cellulose. You will need about 300 cubic feet of blown in cellulose for an attic. If it's 2x10 rafters you will need about 336 square feet of 2x10 insulation blankets that are the width of the space between your rafters. If it's 24 inch on center rafters, you will need 24 inch blankets. You will need about 660 square feet of insulation for the walls, less the area of the doors and windows. Again, if it's 24 inch on center 2x6 walls, get the appropriate insulation blankets.
What are the common uses for 2x4 dimensional lumber in construction projects?
2x4 dimensional lumber is commonly used in construction projects for framing walls, building structural supports, creating door and window frames, and constructing various types of furniture and shelving.
