Blended Wall R-Values Print By and large, walls are made upward of several layers of dissimilar materials. The R-value of a composite wall is calculated by adding the effective R-values of each of the layers of the wall. For example, the epitome below shows a wall made up of four layers—½ inch drywall within for aesthetic purposes, real insulation in betwixt the studs, ¾ inch plywood capsule outside, and wood siding equally the final exterior finish. Together, the layers of the wall are preventing estrus loss. Diagram of a wall We can calculate this wall’southward blended R-value by adding the R-values of each layer. Plasterboard 1/2 inch + Fiberglass inches per inch + Plywood 3/iv inches + Woods Siding 1/ii inch —————————————– Total R-Value of Composite Wall We can find the R-values for the walls by using the table from the page well-nigh R-Values the table is repeated beneath Building Materials and their R-Values Fabric R-Value ftii o Fh / BTU Obviously glass, 1/8 inch Stone per inch Common Brick per inch Asphalt Roof Shingles one/2 inch Gypsum Lath Drywall or plasterboard Woods Siding, i/ii inch Plywood, 3/4 inch Insulating sheathing, 3/4 inch Fiberglass, per inch battens Polystyrene per inch Polyurethane Board per inch Cinder Block 12 inches Plasterboard 1/2 inch = + Fiberglass inches per inch = + Plywood 3/4 inches = + Wood Siding 1/ii inch = —————————————– Full R-Value of Composite Wall = ft two ° Fh Btu Examples Instance one A ceiling is insulated with plywood, 2″ of polystyrene board, and a 3″ layer of fiberglass. What is the R-Value for the ceiling? Solution The ceiling consists of iii layers, and all 3 layers together foreclose the oestrus loss. So, we need to add the R-values of all three layers ” in plywood has an R-value of 2″ of polystyrene at per inch volition have an R-value of three” of fiberglass at per inch will have an R-value of So the R-value of the ceiling is fttwo oFh / BTU. Pinkish insulation in the ceiling Example 2 Please sentry the following one31 video presentation about Instance 2. A wall consists of forest siding R = plywood R = of fiberglass R = and plasterboard R = What is the composite R-value of the wall? Click hither for a transcript of Composite Wall R-Values Problem i video. Lesson 7b, Screen 7 Blended Wall R-Values Instance 10 This trouble, we need to calculate blended R-value. The wall consists of four layers. I half inch woods siding, and its R-value is given straight abroad for half inch as .81. And we have three quarter inch plywood and this plywood’due south R-value is likewise given every bit .94, this is for iii/4″. Whereas the fiberglass, each inch has a R-value of We are using 3 and a one-half inches. And so, times would give us about R-value. And the terminal layer would be one half inch plaster board which is likewise drywall and its R-value is given as .45. 1/2″ wood siding iii/4″ plywood three 1/two Fiberglass 1/2″ plaster lath Total So when you add these up you become which means the composite R-value of this wall is degrees F, pes squared, hour over BTUs. = ° F f t two h B T U Example 3 Please sentinel the following 118 video presentation well-nigh Instance 3. What is the R-value of a wall that is made upwards of wood siding R = 5” of fiberglass R = per inch, and a layer of drywall R = Click hither for a transcript of Composite Wall R-Values Problem two video. Lesson 7b, Screen viii Composite Wall R-Values Example 11 What is the R-value of a wall that is made up of woods siding R= 5” of fiberglass R= per inch, and a layer of .v” drywall R= Here we have, again a wall made up of three different layers. The first layer is wood siding which is outside, obviously, and its R-value is given as whatever the thickness might be of that wood siding. And nosotros take a second layer of fiberglass. And this fiberglass thickness is given as five” and its R-value is given as per inch. So nosotros are using v inches and so 5 times would be And nosotros have a tertiary layer of a drywall and this drywall has an R-value of half inch drywall. Forest siding 5″ fiberglass 5× Drywall Full R-value When yous add all these 3 layers up, y’all get a total R-value of So the answer is degrees F, human foot squared, hour over BTUs. This is the composite R-value. C o m p o s i t e R − v a l u e = ° F f t 2 h B T U Example 4 Please watch the following ane44 video presentation about Example 4. A wall is fabricated upwards of eight” of rock, three” of polyurethane board, and of plywood. Summate the composite R-value for the wall. Click hither for a transcript of Blended Wall R-Values Problem 3 video. Lesson 7b, Screen ix Composite Wall R-Values Example 12 A wall is made upwardly of 8” of rock, three” of polyurethane lath, and of plywood. Calculate the composite R-value for the wall. This is a problem where we accept iii layers for a wall and those iii layers are fabricated up of stone, polyurethane lath and plywood. The first i is rock and its thickness is 8” and each inch of stone wall will provide an R-value of Therefore, all these 8” together would provide And the second layer is fabricated up of three” of polyurethane and each inch provides an R-value of therefore, together, all 3” would provide an R-value of The tertiary layer is once more 3 quarters inch plywood and information technology provides an R-value of So all these three together would have an R-value of or the composite R-value is degree F, foot squared, hour over BTUs. 8″ stone three” polyurethane plywood Total C o m p o s i t e R − 5 a fifty u e = ° F f t two h B T U Insulation Needs Past Region The Usa map below shows insulation needs by region, equally indicated past color and numbers.
