New Home Insulation

The go-to Insulation Company Builders Choose for Reliability and Quality

Install Green Home Insulation To Increase a Home Values

Building a house isn’t just putting the bricks together, you know that. You need professionals you can rely on for technical expertise to make the new building safe, energy-efficient, and comfortable. Hiring a professional insulation company can provide you peace of mind that the insulation of your new house is in good hands.  

Builders are well aware that material costs may add up quickly, but insulation is one area where you should never skimp. It may add significant value to a home, and with Connecticut’s severe winters, a house with adequate insulation can attract more buyers. Therefore, it makes sense for a savvy builder to insulate to the maximum level.

At Green Apple Spray Foam, we help in building energy-efficient houses of high value by aligning the insulation plan with other building components. We don’t offer run-on-the-mill solutions. Instead, we support the builders to create the design that allows for the right insulation levels to be achieved.   

We understand that building a house is a complete system. The planning of your project encompasses several areas. Let us help you with the insulation; we will ensure that the right services are provided and the correct approach is taken.

Where do we Insulate in New Home Construction?

Interior and Exterior Wall Insulation

If not insulated properly, exterior walls can allow a lot of air to leak into and out of homes and buildings, which reduces energy efficiency and can cause energy bills to increase.

Attic Insulation and Ceiling Insulation

As one of the biggest culprits of energy loss in homes, attics are a good place to start when you need to insulate. Insulation can be installed in attic knee walls, ceilings, etc. Insulating the attic can help reduce energy loss, which can help homes stay more energy-efficient and comfortable.

Basements/Crawl Spaces

The lower levels of a home (basements and crawl spaces) are a huge source of energy loss and moisture infiltration. Both ventilated and unventilated crawl spaces should be insulated.

Why It Is Important to Add Insulation During New Construction

Oftentimes, adding insulation to an existing home doesn’t ensure enduring performance and efficiency. Insulation is part of a broader system and works best during the construction phase. Proper insulation and vapor barriers must be applied and thoroughly air-sealed while building the home, to provide a tight thermal envelope for maximum efficiency and minimum energy expenses.

It is quite difficult to produce a continuous vapor barrier after the home has been completed and sold, therefore it is vital to get it correctly during the construction period.

Factors We Consider When Insulating New Homes


Spray foam insulation is the ideal way to achieve a proper R-value. However, Foam insulation is two to three times more expensive than standard insulation materials, such as cellulose or fiberglass.

While foam insulation is initially more expensive, the air seal reduces the long-term cost of spray foam through lower monthly energy expenses, no future insulation repair costs, and the elimination of comfort issues that foam insulation resolves.

When constructing a new home, it is essential to consider not just the initial expenditures, but also the lifetime costs and potential problems that the insulation will prevent.

In addition, it is crucial to note that cellulose and fiberglass will settle and degrade with time, losing their insulating effectiveness. This also increases costs because these materials must be replaced.

The selection of insulation material is determined by R-values. R-values vary based on the type of insulation, its thickness, and its density. A material with a higher R-value performs more effectively than one with a lower value. Another factor to consider while choosing an insulation material is budget. While closed-cell foam has a greater R-value, the material is quite expensive. Some builders choose the less expensive options to meet their budget requirements.

Spray foam insulation specifically has an off-gassing period of 24 hours. During this time, all the crew has to vacate the property to stay safe.

You’ll need a different R-Value depending on your location and the area of your home you’re insulating (walls, crawlspace, attic, etc.). R-13 through R-23 are typical recommendations for exterior walls, whereas R-30, R-38, and R-49 are recommended for ceilings and attics.

Applying closed-cell spray foam is the best option to achieve the proper R-value in tight spaces. However, a builder might not prefer closed cell spray foam for several reasons. In this case, fiberglass batting or cellulose is used.
