Call 978-423-6051 today to discuss your project insulation needs. We'll provide a free evaluation of your project and an estimate. Then you can decide if it's cost-effective to subcontract this work and leave yourself free to work on other items.

Having the right specialists on your team can keep a project running smoothly as they apply their specialized experience to your building project. Just as you have traditionally subcontracted work to a trusted plumber as part of your team, you can hire the insulation installers of Pro Insulators, a division of National Lumber.

Building code compliance and OSHA safety compliance are met when you hire Pro Insulators. We have all the proper safety and work equipment. Most importantly, we are up-to-date on meeting codes for energy efficiency and current building standards.

IMPORTANT: Click here for IECC (International Energy Conservation Code) Code Changes
DISCLAIMER: This is an interpretation of the code changes occurring on July 1, 2014 as it relates to the energy conservation component. There are other changes to the code that are affecting other items such as duct sealing, lighting, etc that we are not covering in this presentation. All customers are advised to discuss the changes to their local code official or HERS rater to get answers to how these code changes are going to affect their specific projects after July 1, 2014.

IMPORTANT: Click here for Wall Construction/Insulation Comparison The code requirement is R-20 wall cavity insulation, as the National Energy Code has been adopted by the state of Massachusetts in all townships. Stretch Code townships, however, operate under a different set of design and testing standards, which require outside resources such as HERs raters be used by builders for all areas of energy compliance, thereby relieving the building department(s) of this portion of the building construction review & inspection.

Not all Massachusetts cities and towns have yet adopted the Stretch Code, but those which have are indicated on the map and are enforcing its provisions with tenacity. Click here for a map showing those Massachusetts towns.

Check out the slideshow showing the team at work. You'll see their attention to detail as they locate and fill potential leak areas with spray foam insulation and then install batts & rolls of fiberglass insulation. Observe their methods as they systematically work around plumbing and wiring to guarantee all areas are covered.

The team also install Blown-In Fiberglass Insulation. The fiberglass insulation is sprayed into a wall cavity, completely filling in around pipes, wires, electrical outlets and other objects, significantly reducing voids and air gaps, resulting in high R-values.

If you prefer spray foam insulation, we also install open and closed cell foam. Click here or on the photo at upper left for a photo slideshow of these products.
