Developing the modeling effort in man hours there is A LOT of R&D cost most builders cannot afford. DIY work involved. Typically, a higher insulation R rating means better climate control and better energy efficiency for your home. I now know that the A/C reduces the temperature of the air so that the living space can then transfer its heat to the cool air. Includes on site setup, site preparation, job completion, trash removal and work area cleanup. But OK split the difference, call it 2lbs. That is where it gets complex, ORNL attempted to quantify it using concrete but, fell far short. can be considerable. Synthetic manufactured gypsum is a bad choice, most concretes with high levels of portland cement as the binder is another. It's calculable, but it's in the measurement noise of a real house. Helps reduce interior and exterior noise, Seals gaps for air tightness. Some have a reported a 10 degree load drop at the expense of running a water pump. All Rights Reserved. I agree with Nathaniel a pitfall of the industrial revolution and manufactured products that cost more and do not perform as well. The only major heat sources at night: 2 people & a refrigerator. That's why even though radiant barriers at the rafters will reduce the peak attic temps in a ventilated attic, the energy use benefits of radiant barriers when there is R50 on the floor is in the statistical noise (less than the estimation error of air infiltration rates in most load calculations), and not cost effective. R-value measures how well building insulation can prevent the flow of heat into and out of the home. Improves moisture control. I really liked Michael's comments on something to be aware of. Keeping the house at constant temp would be both more comfortable, and it will use less overall cooling energy. The mass / heat diffusivity effects on peak & average cooling & heating loads are at least measurable in R-C-R assemblies, where that C is concrete (such as a 6" wall built with insulated concrete forms), but that's more than an order of magnitude greater thermal mass than we are talking about with 2lbs per square foot of cellulose. Reflectix requires only basic tools: A stapler, tape measure, utility knife, straight edge and safety glasses. And soon the sun will be out, heating the roof and the attic again, causing the same process to repeat. Since our insulation is fibre free, no protective garments or respirators are required. Includes basic coverage quantities and typical overage. When my A/C is on, it has no problem cooling down the space; it is functional & effective when it is turned on - don't know where I mentioned that it couldn't cool the house. That way, the heat flow will not only be lower, but there will be less heat stored in the insulation, and finally--critically--the direction of heat transfer can reverse during the night, which will actually pull heat OUT of the insulation, “recharging” it for the coming day, and potentially even pulling some heat out of the ceiling drywall too. Another way to cool mass if you had it is HR, pump water from the hot mass during the day to the metal roof at night to cool by night time radiation, send the cool water back to the mass during the day. There is also a case here for eliminating the roof sheathing entirely to reduce the weight and turn the underside of a bare metal roof into an automatic radiant barrier, as long as there’s enough racking resistance added instead. Input project size, product quality and labor type to get R60 Insulation material pricing and installation cost estimates. Thankyou Peter & David. I imagine budget constraints, it does take lots of R&D money. It uses a sheet of paper to control moisture vapor between walls and floors. The thermal mass of open-blown R60 cellulose is about 3x as much, but still small ~0.33 BTU/ degree-F-lb at about 2lbs per square foot of ceiling, for about 0.66 BTU/degree-foot^2 . As a general rule of thumb we seem to find here in warm humid N. Carolina (a very broad rule, with many exceptions according to the specific condition of the home), attic insulation upgrades improve heating season performance, closing and insulating vented crawl spaces has the greatest impact on summer cooling performance. Foam board insulation is easy to install between wall studs and over existing blanket insulation. Like you, I'm interested in hearing Dana's response.
