Improve Home Performance with Spray Foam Insulation

Published on: August 23, 2012

With the rising cost of energy, everyone is interested in how they can reduce their heating and cooling costs. The price of keeping interiors at a comfortable temperature can easily exceed 50% of total energy costs.

This article will discuss a few ways that spray foam insulation can be used to increase the energy efficiency of your home.

Spray foam insulation can be used to optimize the performance of attic insulation in two different ways, and it can also be used in AC maintenance.

Attic insulation – floor

Spray foam insulation can be used both as attic insulation and as an air barrier. In cold and mixed climates, it’s currently standard practice to lay attic insulation in between the attic joists or truss bottom chords. However, without a great deal of ventilation, the warm, moist that leaks into the attic from the house below through recessed lighting, electrical and HVAC penetrations can cause chronic condensation on the underside of the roof structure. The moisture promotes the growth of mold and rot, and after 10-20 years, the roof structure can be badly damaged.

Spray foam insulation not only blocks the passage of heat, it blocks the passage of air. It can be used to seal electrical and HVAC openings in the attic floor, and it will help to prevent condensation on the underside of the roof.

Attic insulation – ceiling
Spray foam insulation can also be used to insulate the underside of the roof. In climates where cooling is the main issue, air conditioning ducts are often routed through the attic. Insulating the attic floor leaves the ducts above exposed to very high temperatures. Spray foam is a convenient and effective way to insulate the attic ceiling rather than the floor, making the loft a temperature-controlled space where the ducts will stay cool. It will also leave the attic fully accessible for AC maintenance.

AC maintenance

Spray foam insulation can also be used in AC maintenance. It can seal ducts and air conditioning equipment on roofs and in unconditioned spaces, such as attics with insulated floors. It can also create a continuous layer of insulation on the outside of exposed ducts. This helps to ensure that your conditioned air will still be cool when it arrives at your living or work space. Paying for air conditioning and then allowing the air to heat back up in the ducts is like throwing money away.

A qualified and reputable HVAC contractor can choose the right spray foam insulation for your needs, balancing cost and energy efficiency. Spray foam insulation is an amazing product.
