about 9 1/2 inches thick
The higher the R-value, the better the insulation. Therefore, a material with an R38 insulation value will have less heat loss compared to a material with an R30 insulation value since it provides greater resistance to heat flow.
Using fiberglass insulation R30 in a residential property provides several benefits, including improved energy efficiency, reduced heating and cooling costs, better sound insulation, and increased comfort for occupants.
An R30 requires 12". You will need to look into the spray foam installation. I think it will need to be around 8 to 10" for an R38.
The benefits of using R30 faced insulation in a residential property include improved energy efficiency, better temperature regulation, reduced energy costs, and increased comfort for occupants.
The benefits of using r30 batt insulation in a residential property include improved energy efficiency, better temperature regulation, reduced energy costs, and increased comfort for occupants.
R 13 for 3.5" wall cavities, R19 for 5.5". R30 for blown in insulation and batts in ceilings.
R30 fiberglass insulation is beneficial for home renovation projects because it provides high thermal resistance, helps reduce energy costs, and improves overall comfort by maintaining consistent indoor temperatures.
Everything is geared tward energy conservation. A R30 attic blanket is the standard. R38 is better.
57% gain. A R30 would be the same as a R19 + a R11 batt.
This is the process commercial insulators use. It involves a large truck mounted blower and as much as 200 feet of hose to shred and blow insulation into an attic area. If you are a do-it-your-selfer, you may want to consider R30 batts.
