I invite you to explore my YouTube channel, where you'll see first-hand how insulation looks in dark and mysterious attics, crawl spaces, and basements scattered across Maryland. Witness first-hand how we tackle the unique challenges found in these hidden spaces, and gain valuable knowledge on how to conquer your own house.
Written by Eric Gans, Building Analyst & Envelope Professional I'm a certified energy auditor and insulation contractor in Maryland. I have completed over 2000 energy audits and taken over 2000 trips to an attic.
Maryland Home Insulation Guide
An under-insulated attic is the #1 reason for poor home comfort and high energy bills. Use this guide for Maryland home and attic insulation solutions.
1. No significant gaps
2. Fits in any cavity
3. 13-18" Depth
Does that look or sound like your attic insulation?
Not likely...ENERGY STAR says 9 out of 10 homes are under-insulated, and everything I see in Maryland attics proves it.
According to a recent Forbes Magazine article, there are approximately 124 million houses in the United States, and roughly 20% were built before 1980. Older homes mean older, outdated methods of insulating that don't measure up to today's standards.
So where do you begin? This guide can help. It will answer many of the questions homeowners have about insulation.
Winter: We place caps on our children's heads on a cold day to keep the heat from escaping, and we need to do the same to our homes. Check out these great ways to change the trend and get a hold of always being cold:
Preventing Rapid Heat Loss -Attic air sealing is one of the most effective ways to improve home comfort and energy efficiency - learn the basics.
Improving Indoor Air Quality -Learn about the relationship between indoor air quality, air changes per hour, and energy efficiency for your home.
It is essential to measure insulation through a different lens. Try not to focus on which insulation is better. Instead, please focus on the proper R-value, especially for the places where it is most important.
There are two things to know about R-value:
1. How to Measure R-Value
Insulation has one job - to resist heat flow. The higher the R-value, the better the insulation resists heat transfer.
2. How R-Value Requirements Change
As your home's features twist and turn, insulation requirements change. R-values decrease in less critical areas.
Batt Insulation: Prevalent and, unfortunately, the worst performer.
How Much Does Insulation Cost?
Home Performance contractors look for insulation fixes in existing homes that will make the most impact for the lowest cost. Accessible areas are first priority and usually the most important. Investigation and testing play a role in helping to shape solution decisions. Taking this approach will factor in the overall cost.
Here are important considerations if you plan to insulate your home:
ENERGY STAR® says to look at the many systems around your home. Evaluating the "whole house" can lead to better comfort and efficiency. Their stats show that 9 out of 10 homes in the U.S. are under-insulated.
Maryland Utilities (BGE & Pepco) offer a portfolio of programs promoting energy efficiency and conservation, including rebates, education, and services. The program is designed around a consultative approach.
Air sealing and insulation are considered the most critical measures to complete to achieve energy efficiency - before windows, doors, and replacing older HVAC. The initial qualifier for rebates is to get a home energy audit.
Why is the room on the front of the house colder? Do you have enough insulation? Why is it so stuffy upstairs during the summer? Should I remove old insulation from my attic? Why does my HVAC run all of the time? Is spray foam insulation the best solution for my home? Why are my new windows feeling drafty? Do my walls have insulation?
