There’s a reason why an increasing number of people choose to call Florida home. The beautiful weather and gorgeous landscapes can’t be beaten. However, as with any warm climate, special considerations need to be taken to ensure that a house, whether new construction or an existing home, is as comfortable and cost-efficient as possible, all year-round.
The importance of residential insulation
It may seem like a house in a temperate area like Miami wouldn’t need much insulation, but the opposite is true. While houses in colder regions of the country require insulation to keep the heat in, homes in southern Florida must be insulated to hold the heat at bay and minimize the amount of work the A/C has to do.
The history of insulation use
People have been using some form of insulation for millennia. From fur-covered hides stretched over wooden frames in prehistorical times to the advent of fiberglass insulation in the 1930s and modern blown-in foam, insulation has played a significant part in making homes more comfortable and hospitable. Luckily, there is no longer a need for hair-on hides, but the modern options are greater than ever.
The best types of insulation for South Florida homes
Choosing insulation that matches the architecture of a home is important. For instance, a house with a vaulted ceiling will require a different type of insulation that will work with the home’s interior design, as opposed to a single-level ranch where it will not be obvious. The most crucial factor is the R-value of insulation. R-value indicates how well insulation will perform in keeping heat from either entering or leaving your home. The higher the number, the more efficient it will be.
Batt insulation is sold in rolls or strips. It is appropriate for walls, ceilings, and floors. It is made from fiberglass or rock wool and, while one of the older forms of insulation, it is still popular.
Blown-in Fiberglass or Cellulose Insulation
Both blown-in fiberglass and cellulose insulation gained popularity between the 1950s and 1990s. They are a particularly popular option for attics and walls. Cellulose has been shown to have a higher R-value than fiberglass. The downside to these insulations is that they can be messy if attics or other areas must be accessed regularly.
Spray Foam Insulation
Spray foam insulation has become a popular choice for many homes. It is easily applied (by qualified contractors) to walls and roofs and is shown to be watertight while having a high R-value.
Also known as foam board insulation, rigid insulation can be used in any part of the home. It can be cut to size and is easily removed if need be. It is advantageous in areas where blown-in or foam insulation may not be practical.
Foil insulation is an excellent option in hot climates in that it reflects heat away from the foil surface. Its thin composition makes it ideal for pairing with other insulations, such as batt insulation. Therefore, installing the foil side facing out will keep heat from moving through the walls and roof into the living areas.
