Radiant Barrier Vs Spray Foam

A significant issue cropping up in case of home insulation, especially if you live in a city which records soaring temperatures during the summer, is the idea of reducing the heat your attic is prone to absorbing.

There are two conventional alternatives to insulating the attic –

  • Radiant barrier sheathing
  • Spray foam insulation

Radiant barrier sheathingRadiant barrier sheathing can reflect back up to 95% of the heat absorbed and can consequently reduce attic temperatures by up to 20 degrees F. This means that radiant barrier sheathing keeps your home comfortably insulated against outside heat and saves energy your power utility bills up to 17%. The installation of the radiant barrier sheathing does not require any special tools or professional expertise. However, radiant barrier sheathing can only be used if your house is in one of the cooling climate zones 1,2 and 3. In addition the whole roofing has to be redone if it is to be installed with the sheeting facing the house and there must be a good amount of airflow space in the attic for the radiation method to work. If the ventilation in the attic isn’t adequate, then the water vapor wafting upwards from the house could condense on one side of the barrier causing the existing insulation to lessen in efficacy. The use of a tough radiant barrier material will also reduce efficiency and lead to fast wear and tear.Spray Foam Attic insulation Tucson Job

Spray foam– Spray foam is another option if you are planning to insulate your attic since it succeeds in keeping out heat during the summer months thanks to its high R-values. Spray foam is good for insulating small buildings and tricky nooks and crannies. Spray foam, although quite expensive, has the capacity to last for decades and can withstand high and freezing temperatures for up to 80 years. If the air ducts in your home are placed in this space, then spray foam will aid in the heating and cooling processes. Spray foam is known to reduce power bills by a wide margin and prevents the entry of dust, pollen, water vapor and air when installed properly. It prevents spread of heat through convection because the foam obstructs the flow of air through it under all circumstances. Aside from all these advantages, spray foam also allows you to move the divide between conditioned and unconditioned spaces from the attic floor to the roof without needing to change the general design of your house. The only downside to using spray foam is that it is quite expensive in comparison to other forms of insulation and cannot be installed without professional assistance.
