What is the standard framing stud size?

Most homes in North America are framed with 2x4 and 2x6 studs. Newer, more efficient homes take advantage of 2x8 studs allowing for more insulation and a higher R-value wall. The standard lengths for 2x4 and 2x6 studs range between 8 feet and 16 feet.

Are insulated studs code compliant?

Yes, insulated studs comply with building codes in the United States and Canada. They have also met ASTM (American Society for Testing and Materials) standards.

Are insulated studs energy-efficient?

Yes, insulated studs are very energy efficient. Traditional studs have an R-value of 6, while insulated studs carry an R-value of 20 but may differ depending on the type of insulation you use.

What is the R-value of an insulated stud?

Insulated studs are energy-efficient and carry an R-value of 20, compared to traditional framing's R-value of roughly 4.38 and 6.88 for 2x4 and 2x6, respectively. They create a 99.23% complete thermal break with the stud, meaning nothing gets through. Studies found the thermally broken wall assembly, like those made with Tstuds, is 150% to 280% more efficient than standard 2 x 6 framing.

What types of insulation can use with insulated studs?

Insulated studs can come pre-filled with insulation factory direct. Builders and homeowners also can purchase an uninsulated assembly to add any insulation type of their choosing.

Are insulated studs load-bearing?

Insulated studs are three times stronger than 2x6s. Builders can use insulated studs to construct buildings up to 6 stories and walls up to 16 feet.

Do insulated studs reduce the amount of lumber required for framing?

Yes, the load-bearing strength of insulated studs reduces the number of studs required to frame the average home by up to 58 wall studs.

Are insulated studs soundproof?

Thermally broken wall assemblies absorb noise and can reduce sound by 22%. United States Gypsum found that broken wall assemblies offer a +6 sound transmissions class rating.

Are insulated studs fire resistant?

Insulated studs offer a Class A rating on the Y-axis fire rating compared to Class C for traditional 2x6 studs. An E84 flame spread test found 90% structural strength retention in insulated studs, which have also been extensively tested by UL.

Insulated studs are a replacement for the traditional 2x6 stud used in framing. An insulated stud contains two boards separated by 2.5" of space for insulation. The open space can be pre-insulated at the factory with closed-cell foam, or builders and homeowners can add insulation during installation. Insulated studs add structural integrity and offer a solution to heat loss through home framing.

Traditional studs are a weak point in high-performance building because they have a low R-value, indicating they allow heat to transfer quickly. Insulated studs create an almost complete thermal break with the stud meaning virtually no heat can move through. If you select an insulated stud assembly without preinstalled insulation, the builder or homeowner can choose a preferred insulation type. In this scenario, it's essential to consult with the manufacturer about the best kind of insulation.

Studies found that thermally broken wall assemblies are 150% to 280% more efficient than traditional 2x6 framing.

While the number of studs for the average home decreases by 58 when using insulated studs, insulate studs also reduce the need for up to 200 lineal feet and 2,000 fasteners.
