Questions

How does insulation work?

Heat flows naturally from a warmer to a cooler space. In cold weather, it flows from heated rooms to the unheated attic, garage or basement, or to the outdoors. In hot weather, heat flows from outside your home to its interior. To maintain comfort, the heat lost in winter must be replaced by your heating system, and the heat gained in summer must be removed by your air conditioner. Insulation resists the flow of heat, preventing unwanted circulation. Thus, in a well-insulated house, rooms stay warmer in winter, cooler in summer, with less energy expenditure.

What is the benefit of attic insulation?

Heating and cooling account for more than half of the energy use in a typical U.S. home*, making it the largest energy expense for most homes. You will save on your energy costs if you reduce the amount of energy needed for heating and cooling. Insulation helps your home retain heat in cold weather and reject heat in warm seasons. *For more information visit: http://www.energy.gov/public-services/homes/heating-cooling

Doesn't my house already have insulation?

The insulation you have may be inadequate or improperly installed. It is also possible that the R-value of your existing insulation has degraded over the years. If your home has drafty rooms, uneven temperature between rooms, high heating or cooling bills, or ice dams in winter, we recommend inspecting your insulation. Even in newer homes, additional attic insulation could save money in reduced utility bills, and those savings can continue year after year. Upgraded attic insulation may also increase the value of your home.

What is a radiant barrier?

In residential applications, radiant barriers consist of a highly reflective material (spray or foil), which reflects radiant heat. When properly installed, it can help save money in reduced utility bills.

Why use a spray-on radiant barrier?

A spray-on radiant barrier is an innovative application of a high-tech material that safely reflects radiant heat. It has great advantages over other types of radiant barriers (like foil) including better coverage and a longer effective life-span. It is sprayed over all nail punctures in a uniform manner, so there are no holes or gaps. It does not create a vapor barrier, so it will not contribute to mold, and it does not affect antenna and mobile phone reception.

Where is SolaShield™ installed?

SolaShield™ is sprayed on the underside of your roof deck. By applying a thin, even coat of “liquid foil,” SolaShield™ can stop up to nearly 80% of the sun's radiant heat before it enters your attic space.

How long does SolaShield™ take to install?

Depending on the pitch of the roof and maneuverability, most installations can be completed within two to four hours.

Is there an odor associated with SolaShield™?

As with most paints, there is generally a minimal odor that will disperse within a few hours after application. Since SolaShield™ is applied in the attic, most homeowners will never notice an odor.

How many coats are required?

One single coat of SolaShield™ will form an effective radiant barrier and block up to 80% of the sun's radiant energy from entering your attic space.

How long does this product last?

The SolaShield™ radiant barrier by EAS has the durability of a premium latex paint. It should provide up to 25 years of service and energy savings.

What is R-value?

The R-value rating refers to the insulation's thermal resistance - its ability to resist heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and density. Adding more insulation in your home generally increases the total R-value and the resistance to heat flow.

What does emissivity mean?

Emissivity is the factor that determines the amount of radiant heat allowed to pass through the material, or in other words, the amount that is not reflected. SolaShield™ has an emissivity of 0.23, therefore it reflects up to nearly 80% of the sun's radiant heat hitting your roof.

Wouldn't the most energy-efficient home be one that is the most airtight?

Controlled ventilation and air leakage are two different matters. Sealing unwanted air leaks is vital to a home's energy efficiency. However, controlled ventilation in your attic is also very necessary.

Do I need an attic fan?

Proper ventilation is very important to having an efficient attic. In winter, the colder outdoor air keeps your attic cooler to minimize the potential for creating ice dams from excessive snow melt. In summer, the fresh air helps remove moisture and keep your attic/home cooler. Attic fans are designed to keep attics cooler in summer by using electricity or solar power to encourage good air circulation. However, if the soffit vents are blocked or if there’s no other venting, attic fans can actually pull cool air out of your house into the attic. The ventilation experts at EAS can offer the best ventilation solution for your attic to optimize your energy savings.

What kind of ventilation system do you recommend?

The Energy Efficient Attic® solution employs a ridge vent at the peak of the roof, plus vented soffits under the eaves. However, depending upon the structure of your roof, other systems may be recommended. We also install wind turbines, air hawks, and a variety of powered and solar-powered vents, if appropriate.
