Insulation helps keep your building cooler in the summer and warmer in the winter. Combined with a good sealing effort it can also reduce persistent moisture-related problems such as floor squeaks, drywall cracks, and condensation damage. Cooling a South Florida building consumes 35%-50% of energy costs. With the correct insulation R-value in your attic, you could save as much as 20% on your energy costs (typically around $320.00 per year). 

Benefits of Fiberglass Insulation

Upgrading your attic with fiberglass insulation gives superior performance and benefits to help increase your comfort while lowering your energy bills.

  • It is made up of 100% renewable materials (60% sand and 40% recycled glass).
  • Nothing is added – no binder, glue, chemicals, or additives. 
  • It will not itch, crush, or settle over time.
  • It will not settle or lose its energy-saving abilities over time.
  • It does not require the addition of fire-retardant chemicals which could promote corrosion of pipes or wires.
  • It will not rot or decay, support fungus or mold growth, or provide sustenance for insects or vermin.

Making your building more energy efficient can be achieved with the right type of insulation. The two most popular types of insulation are fiberglass and cellulose. Which type is best for your home? Watch this video to see a safety comparison between fiberglass and cellulose to help you decide which insulation you can trust.

R-value refers to the thermal resistance of insulation. Heat moves in three ways: conduction (through solids such as insulation), convection (through the air), and radiation (through electromagnetic waves). The higher the R-value of your insulation, the insulating power it has. Every insulation type has a different R-value, with fiberglass having the greatest R-value. The amount of insulation you need is determined by many factors, including the climate, the type and size of your building, and your fuel use patterns. How your insulation is installed also affects the R-value, which is why it is essential to work with a professional installer.

Do NOT install Icynene insulation in your attic.

  • It voids all roofing manufacturer’s warranties
  • It voids Kelly Roofing workmanship warranty
  • Not recommended by the American Plywood Association
  • Currently, there are discussions of outlawing Icynene in the next revision of the Florida Building Code
  • Why? There have been incidents where a small roof or plumbing leak in buildings where Icynene was applied and caused severe structural damage and roof cave-ins before the building owner ever knew there was a problem.
  • How? Icynene, both open cell and closed cell, skims over during curing to create a waterproof layer and trap water. If a leak occurred you would not know about it until it is too late. The trapped moisture rapidly rots out wood trusses and decking. In one such case, the roof caved in and came through the ceiling right into the master bedroom. Luckily the owners were not home when it happened.
  • We strongly discourage Icynene installations and suggest proper ventilation to provide the greatest benefit.
  • Not ventilating has been shown to increase asthma and allergies.

Roofs and attic spaces have two major enemies: heat build-up and moisture accumulation. Left unchecked, these forces can cause premature deterioration of the roof structure and materials. They also damage insulation and increase energy costs. The only defense is proper attic ventilation. An effective well-balanced roof ventilation system allows air to move in a pattern which results in a uniformly cool attic space prolonging roof life and increasing living comfort.

  • Many people don’t know they’re sending money through their roof.  Overall, about 60 million homes in the U.S. are under-insulated, costing Americans $8.2 billion each year.**
  • Simply insulating existing homes to current standards would save 800 trillion BTUs (that’s 76 supertankers of oil) each year. A standard single-family home going from an existing R-19 to R-38 will see a minimum reduction of 20% on their cooling and heating bills. If your electric bill averages $200.00 per month, about half of that is typically for cooling and heating.
  • A 20% savings would equate to a $20 reduction on your bill each month.  
  • About 78% of homeowners have not added any insulation to their attic; in part because they believe their home already has enough.**
  • However, 80% of homes built before 1980 are not insulated to government standards.**
  • Even newer homes may not be as energy-efficient as you think. State energy codes are only the minimum insulation requirements for new construction–not the amount recommended to optimize energy efficiency.
