You work with the same person through the entire process for continuity so there’s no confusion. After all, it’s all about those little details. Cover that treadmill or seal around that particular drafty door where my daughter plays the piano.

How home insulation works

Go from insulation geek to insulation guru. Knowledge is Power.

Einstein always said, make things as simple as possible, but not any simpler. Our goal with this section is to demystify insulation. To truly understand home insulation, it is critical to understand the fundamentals of heat transfer. We break this down in Insulation 101 and Insulation 102. Also we hope to continue to bring you more projects with Our Blog and Our Videos. Think we may be the right home insulation company for you? READ OUR FAQs here.


Why the Lab?

We call ourselves Mass Energy Lab Insulation because we realized that there is a gap in the insulation industry. A gap between the disciplines of physics and materials science and the construction industry. And that gap isn’t in a lab. It’s in the field, where the insulation is actually being installed. We have heard many roofing contractors talk incorrectly about “breathing roofs”, as well as many HVAC folks talk about “hot roofs” and attic ventilation in a manner that defies the laws of physics, just because it can be confusing. We see and hear highly suspect implementations and explanations of vapor barriers, water-resistant vs water-repellent, causes of ice dams, even the seemingly lowly water pipe insulation wraps. We believe our customers deserve real, science-backed explanations. Its one of the many reasons why we use an infrared camera on all home insulation assessments. After all, it’s your home.

Learning about Insulation is not enough. We must also learn about how insulation acts and reacts with other components of the home. Its why we've completed the Mold Remediation Training and Certification. Just so we can understand how and why mold grows in homes and how do we actually work to make sure that insulation installs don't cause a mold issue. Its why we've completed HVAC trainings and certification, along with the ASHI (American Society of Home Inspection) trainings and certifications. We even have completed all the ASHRAE 90.1 Ventilation Design, Assessment and Install Certifications for homes so that we can understand exactly how much a home should "breathe".

Our quest for learning all about home insulation starts with learning all about homes. This is critical to understand for all industry trades, in our opinion.


We are on a mission to bridge this gap between science and construction installations. We follow physics first principles such as heat transfer and the laws of thermodynamics. We understand the chemistry involved and extrapolate it to your home’s benefit. All with good craftsmanship. We are on a mission to ensure that when we install insulation and ventilation solutions in your home, it always solves your problem, not causes more. Hey, we're a Cambridge, Massachusetts-based company. What else did you expect ?


WE ARE A LEARNING ORGANIZATION. We want to learn about the latest in construction, building science, insulation, ventilation and so on. Below are some of the latest research and training conducted by our teams to understand how insulation works.
