Spray Foam Insulation Pros And Cons

 

Spray foam is slowly becoming the favorite go-to option in the insulation material category for both home-owners and outdoorsy building makers. Its high popularity levels could also be attributed to its easy application and affordability. Fibreglass which has been so far used to insulate buildings against the onslaught of air and water vapor, commands a higher price than spray foam. Homes built with spray foam insulation also have a higher likelihood of ensuring comfort for its occupants aside from outdoing the efficiency of homes with fiberglass insulation.

The following is a list of advantages and disadvantages of using spray foam insulation –

Advantages

  • While fibreglass insulation easily breaks, leaving gaps through which moisture, outside heat can seep into your home or the warmth of your home can dissipate into the atmosphere, spray foam enables you to fill these gaps and salvage the insulation
  • Spray foam helps guard against invasion by insects including termites, woodlice etc.
  • The ordinary home-owners spend up to $650 on heating and air-conditioning purposes in a year. But spending a little bit on spray foam insulation can help tone down those escalating energy expenses by upto 40% every year
  • Prevents dust and pollen infiltration, reduces the chances of mold growth
  • Secures the structural integrity of the building
  • Helps in soundproofing
  • Lessens the chances of ice damages
  • R-value of spray foam remains consistent over time over fibreglass
  • It does not wilt or settle and remains in place for a long period of time

Disadvantages

  • The cost of spray foam insulation is significantly higher than traditional forms of insulation
  • The insulation procedure requires experienced professionals and generally isn’t a do-it-yourself project
  • Spray foam needs to be injected precisely into the blind spots in any building otherwise the insulation can be breached any time; too much or too little spray foam could cause damage in other ways
  • In certain rare cases, spray foam can shrink and pull away from the framing, instead of hardening and expanding. This is often witnessed in case the constituent chemicals of the foam are of poor quality or due to careless mixing at a higher temperature
  • When installed improperly, spray foam could result in problems like giving off a fishy malodour and causing breathing troubles in some people and even young children. Thus contractors hired should be efficient workers and vigilant about such lapses.
