Note: Doesn’t tell you what type of insulation system to use.The Total R-value required is achieved by adding the R-Value of the basic elements, i.e.: roof and ceiling or walls, and the R-Value of any additional insulation incorporated in that element (described as the 'minimum' added R-Value of insulation). The Total R-Value of the basic roof and ceiling has been determined by adding together the R .R-value is the measurement of a material's ability to stop heat transfer. If two products have the same R-value, they have the same efficiency in stopping heat transfer. I thought I had a Higher r-value - Fiberglass Insulation Blankets Lose R-value. Once metal sheeting gets cold it creates a situation where it's colder inside the building that out. I recently did 2x12 douglas fir rafters 16OC with "R30" Rockwool, 7/16 ZIP sheathing (roll the tape!) with 5-1/2" of EPS foam board over it, 2x4 strapping fastened to the rafters through the foam board, and a 5/8 OSB roof deck for shingling - I would have skipped the 5/8 OSB had they gone with metal roofing.
The R values of both metal roofing and asphalt shingles are negligible, but this is not to be confused with energy efficiency. Energy efficiency is a totally different consideration when it comes to roof material selection. Both metal and asphalt roofs are most commonly directly exposed to the sun, and as a result both absorb and release heat. .PROPERTIES DuPont ™ Thermax Metal Building Board Insulation exhibits physical properties as indicated in Table 2 when tested as represented.

Insulation for flat metal roofs. Flat metal roofing can be insulated similarly to pitched roofs. However, there are a few extra considerations to keep in mind. The first is that you can go as thick as a 100mm Anticon blanket, which boasts an impressive 2.3 R-value.Fact Sheet on R-Values of Insul-Deck Floors & Roofs . This is Expanded Polystyrene (EPS) board insulation. Insulation Product Rating . Insul-Deck panels provide R-7.8 h•ft²•°F/BTU [= R. SI. 1.381 m²•°K/W] @ 75° F mean temperature at the concrete joists and the following calculated values between the joists: h•ft²•°F/BTU. Floor .R-value, the better the material's ability to resist the flow of heat through it. The R-value of a material is dependant on knowing its K-Value. The measure of resistance to heat flow, a material’s reciprocal of the K-Value multiplied by the thickness in metres. For example, the k-value for 6 mm ceiling board is 0.19: The R-Value of 6 mm .
For example, a metal roof, which is becoming more popular and more common, will have a lower R-Value by default because the metal is normally an excellent conductor of heat. While they are durable, metal roofs which don’t have proper coating or insulation on them will allow far more heat into your attic, which means a warmer building.
The benefit of low SA and low thermal mass metal roofing is observed in a full-scale study of seven identical homes built in the same street with different roofing, including both white tile, white metal and dark-coloured shingle roofing. 3. The white metal roof performed best at reducing cooling demands being attributed to its thermal behaviour. That means you won’t have to worry about the roof’s R-value decreasing because of a missed spot. Spray foam is one of the preferred insulation methods, especially for renovations. The main disadvantages are the aforementioned purchase cost, as well as the cost of installation because, unlike batts, you can’t DIY spray foam.
