what are the impacts of physics on the society?
I have installed both typesThey both have benefits and drawbacksI prefer blown in because it is a recycled product and if done correctly dose a far better job eliminating the gapsFiberglass insulation is very uncomfortable to work with but if used correctly can do as good of a jobBut, it must be cut properly to eliminate gaps and should not be compressed or it losses it's insulative propertiesOverall, Blow in is quicker and more forgiving but cannot be applied to thickIt compresses over time so it can't be used in walls or on an angle very wellSo if your attic is flat and level I would go with the blow inIt is ease to do yourself and many hardware stores lend you the equipment if you buy the supplies from themBlow in did a better job in my atticShawn
Oakridge National Laboratory created a chart listing the approximate R-value per inch for the various types of insulationAging was factored into the lab’s figuresOnce you determine the existing R-value, you can tell what you need to get to bring the R-value up to your regionYou could get the extra R-value in just one layer of R-30 battsThis, however, would leave the joists exposed and structural lumber has proven to be a key source of heat lossYou get a better insulation job by using two layers of R-15 battsThe first layer goes directly on top of the existing insulation, inside the joistsThe second layer is placed horizontally across the joistsThe second layer encloses the joists, making the insulation more effectiveA more efficient method would be to use blown-in Fiberglass or celluloseBoth would fill all the gaps and enclose the joists completelyBlown-in cellulose gives slightly more bang for the buck because it seals out drafts as well as insulatesWhenever you use blown or loose-fill insulation, it is important to install attic ventilation channels (rafter baffles) to keep the soffit vents from being accidentally blockedIt’s also a good idea to increase soffit and roof or ridge venting whenever you add insulation.
According to the different areas of physics: Classical Mechanics: gears, springs, cars, airplanes, bikes, trucks, motorcycles, cranes, boats, buildings, bridges, tunnels and just about any machine, tool, or structure with moving parts or where balancing of forces is required Electromagnetics: lights, vacuum machines, microwaves, refrigerators, televisions, radios, iPods, telephones, and just about any machine, tool, or structure that uses electricity or light Quantum Mechanics: computers, CD players, DVD players, anything with a flat display screen, solar panels, laser surgery, and just about any machine, tool, or structure that uses a computer chip Beyond providing society with technology, physics explains the universe around us, from the innards of atoms to the motion of galaxiesIn this way, physics impacts society by making us an enlightened, wise, fulfilled and happy people! :)
Blown in insulation is better for many reasonsIf however, you're on a budget and need to save on labor costs, go buy rolled fiberglass and install it yourself for about one-third the cost of blown insulationGood luck
