Q&A

Josh Lowe's Dr. Energy Saver Q&A

Can you add insulation to existing walls?

You can, yet there are many items to consider. During a home energy audit, Josh Lowe's Dr. Energy Saver will be able to inspect and assess home insulation levels. If wall insulation is missing or inadequate, there are several options available to remedy this problem. In terms of improving home energy performance, wall insulation may be the least of your worries. Most homes already have some wall insulation. It's tricky to insulate finished walls because it's more difficult to get insulation inside the wall, in the cavities between studs.

Does the Oregon building code require insulation in the crawlspace?

Western Oregon is in Zone 4, and new construction code here for the floor is a minimum of R-30. For attic insulation, it is R-38 minimum.  However, we do recommend insulating your attic to R-60.  Walls have a minimum R-value of R-21.

How do you get rid of mold?

Mold in your home’s crawl space or attic can develop in a variety of ways. The usual ways are from high humidity in the space, or from water leaking in. This will create perfect breeding grounds for mold.

This hazardous allergen can create ailments so removing mold from your home is critical for your family's health.

Our Energy Consultant will investigate your home to determine what is happening to cause the mold growth.  The first step is to swiftly treat the mold growth and to stop it from growing further. Our company uses Mold-X and Mold-X2, and our energy consultant will work with you to determine which product will be the best choice for your situation.

How much fiberglass do I need in the attic?

We advise our clients to NOT use fiberglass! It is just a big air filter (it just slows down air, rather than stopping it) and rodents love to live in it.

You can re-insulate with fiberglass, but you will have to do it over again and again, and it just never performs as well as all the other options you have. We are amazed that new construction houses still choose to use it.

What is spray foam?

The closed-cell spray foam we chose to use (rather than open-cell) to help make our client’s home more comfortable and energy efficient is a 2-part foam. As it is sprayed, the two liquid materials, a resin and a catalyst, combine and expand. They fill cracks and crevices so it gets rid of un-insulated voids and helps stop air movement. You want to keep your conditioned air that you paid to condition inside your home!

What is the insulation value of spray in insulation?

Our company uses "closed-cell" spray foam, which has an R-value of R-6.8 per inch. 

A client usually has us spray between 2 inches and 4 inches.  It seals everything, eliminating all air gaps and stopping air flow, and has a non-conductive property so heat cannot transfer through it like that of fiberglass.

All these properties make it perform far better than any other insulating materials.

What kind of insulation do I need for my attIc?

Blown-in cellulose insulation and spray foam insulation are the options that out-perform fiberglass. In an attic, fiberglass just acts like an air filter as the air flows through it. You want a giant thick blanket in your attic to help keep your home more comfortable, and spray foam or cellulose will do this. Our Energy Consultant will evaluate your attic and help you determine the best route for your home.

What R-value do I need?

It depends!  Is it your attic, your crawl space or basement, your walls? Plus, what are you looking to accomplish?

The higher the R-value, the better the performance will be for the level of insulation to resist heat traveling through it.

In Western Oregon in zone 4, code for new construction says attics should be R-38.  We recommend R-60 for a better insulating factor. Unless a wall cavity is really really deep, you would not be able to get that much blown-in cellulose into a wall.  Hence why we say “it depends”!

Why are my utility bills so high?

Air you pay to heat, or cool, may be quickly leaking out of your house! You want that air to stay in your home, thereby heating or cooling all the items in your home and keeping YOU comfortable.

There are many places where air can leak out. Attic spaces are notorious for leakage, whether it’s where lights from rooms below are cut in to the attic floor, where the roof meets the house, or construction issues. Even if your home is new, it doesn’t mean it was built well. 

Sealing leaks and properly insulating your attic can be an amazing solution to reduce your utility bills and make you more comfortable in your home. Contact us to set up your free whole home evaluation.

Why is my house so cold?

There usually will be a variety of reasons why your home is cold, thereby making YOU uncomfortable in your home! The best thing is to get a full evaluation of your home by one of our energy consultants.

We don’t just stick our head into the attic or crawl space and say, “Yep, you need more insulation.” Our energy consultants actually suit up with protective gear and crawl into the attic and/or crawl space to see what is actually going on.

Are there can lights cut into the attic and air is escaping from your living space through there? Are your soffits not insulated?

You may have some insulation in your attic and crawl space, but chances are it’s not doing much other than being an air filter (e.g., fiberglass).  Instead of insulating over it, it is better to remove it. Then our insulation crew can cover can lights, seal air leaks, and then re-insulate.  We offer blow-in cellulose and spray foam.

Each situation is unique, so since we offer different insulation materials. Contact us to set up your free evaluation to discover how to be comfortable again!
