It is vital to select the correct attic insulation for your home in Summerlin. Energy efficiency and interior comfort are the two primary concerns any homeowner should have when selecting insulation, and they are especially pertinent in Summerlin's desert climate. Not only does Summerlin experience extreme heat in the summer months, but the nature of desert weather brings wide temperature swings both day and night. Reducing the workload on our air conditioners during those scorching summer months and maintaining a regulated indoor environment no matter what the outdoor conditions are will save us money and allow us to live more comfortably. Fiberglass batts, while still used in many attics, are not always the best choice given their performance-to-price ratio. A better alternative might be to look at using spray foam insulation, which has the added benefit of not absorbing any moisture.
The proper kind of attic insulation for your home in Summerlin will depend first and foremost on the layout and configuration of your attic. If you have an irregularly shaped attic or one with tricky-to-reach spots, loose-fill cellulose is the definitely the way to go. It has the flexibility to pack down tightly in even the most awkward-of-angles, and it doesn't mind working in conjunction with air to help create that "dead space" that makes an attic function as such. Rigid foam board is a less likely option for extensive attics, since its fit is usually less than perfect, but it does very well in the relatively few spaces it is employed for attic insulation. If your home has lofty cathedral ceilings or the not-so-tall "curved ceilings" often found in multisided homes, the best bet may be spray foam or blown-in insulation.
The effectiveness of insulation is determined by its R-value, which measures thermal resistance. Homes in Summerlin benefit from insulation with an R-value that is conducive to our more-than-toasty hottest months; we're talking highs generally over 105 degrees Fahrenheit. These conditioning experts work from the "what if" premise: What if air managed to sneak into and out of the attic? The little bits of outside air that manage to worm their way in become attic occupants that make it just a bit warmer up there. In daylight, a buildup of attic heat can compromise the roof: Intensely radiant sun hits the shingles, which then transfer the heat into the attic. If the attic is poorly ventilated and the insulation is only kinda' sorta' doing its job, the possibility exists that the high temperature in the attic will lead to a low temperature on the other side of the roof (in the house).
