Is OSB good insulation?
LAMINATED TO A. 7/16″ OSB ISOBRACE OSB combines the insulation performance of an expanded polystyrene panel with the rigidity of a 7/16″ oriented strand board (OSB). In addition to providing high performance and continuous insulation, it helps to increase the structural rigidity of the building.

Is 7/16 OSB OK for roofing?
OSB is the most-used sheathing material for new roofs and roof replacements. You can use 7/16-inch thick OSB sheets without support for areas where the snow load is 30 pounds per square foot because it's durable and maintains building integrity much longer than other sizes.
Is 7/16 OSB good for exterior walls?
Wood frame exterior walls must be fully sheathed, including areas above or below wall openings, with minimum 7/16-in. wood structural panels. Interior shear walls must be fully sheathed including areas above or below wall openings with minimum 7/16-in.
Is OSB a vapor barrier?
OSB wall sheathing panels are 'smart' vapor barriers as their permeance is low when relative humidity is low, but it increases as relative humidity increases in the warmer months. This allows for greater air movement which enables the wall to dry faster.
Does OSB board insulate?
59mm Plydeck Xtratherm (PIR with OSB Board) - 50mm PIR + 9mm OSB Board. Xtratherm Plydeck is a composite insulated panel of 50mm Xtratherm Polyisocyanurate core with a composite foil face, bonded to 9mm OSB board. The Xtratherm Plydeck provides a high level of thermal insulation and decking in one application.
What size OSB should be on exterior wall?
Exterior walls Minimum thickness of wall sheathing for use on walls; 3/8" plywood or 5/16" OSB. If you use fibre cement siding, go with 1/2" plywood or 7/16" OSB for the exterior walls.
What material has the best R-value?
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
What is the R-value of Hardie board?
0.37Standard vinyl siding has an R-value of 0.61, and Hardie siding's R-value is 0.37. While vinyl siding is more energy-efficient, neither makes a significant difference in how much energy your home will save.

What are R-values?
In construction, the R-value is the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation.
R-value Units
As we said before, the R-value measures the thermal resistance of a material. This can also be expressed as the temperature difference that will cause one unit of heat to pass through one unit of area over a period of time.
What are U-factors?
Many energy modeling programs and code calculations require U-factors (sometimes called U-values) of assemblies. The U-factor is the heat transfer coefficient, which simply means that is is a measure of an assembly's capacity to transfer thermal energy across its thickness.
Tables of Building Material R-values
The R-values for specific assemblies like doors and glazing in the table below are generalizations because they can vary significantly based on special materials that the manufacturer uses. For instance, using argon gas in a double pane insulating glass unit will dramatically improve the R-value.
Doors and Assemblies
In the chart above, you will notice that there are two vastly different R-values provided for insulated metal doors with polyurethane insulation. Based on ASTM C518 (Calculation Method) the door has an R-value of up to 11, but using ASTM C1363 (Tested/Operable) the same door only have an R-value of up to 3.5.

R-Value Units
- As we said before, the R-value measures the thermal resistance of a material. This can also be expressed as the temperature difference that will cause one unit of heat to pass through one unit of area over a period of time. The two equations above are used to calculate the R-value of a material. Keep in mind that, due to the units, the Imperial R-value will be quite a bit smaller than t…
What Are U-Factors?
- Many energy modeling programs and code calculations require U-factors (sometimes called U-values) of assemblies. The U-factor is the heat transfer coefficient, which simply means that is is a measure of an assembly's capacity to transferthermal energy across its thickness. The U-factor of an assembly is the reciprocal of the total R-value of the assembly. The equation is shown bel…
