Reclaim Your Square Footage With Injection Foam Insulation

Reclaim your square footage and make it all livable again. Are parts of your home like a sauna in the summer or a freezer in the winter? Learn how creating an air seal with foam insulation can make all the rooms in your house liveable.

For several years my husband and I lived in South Carolina. We were in a very middle-class neighborhood in a house that was only about 3 years old when we bought it. The place was great, with a big open plan downstairs and enough bedrooms upstairs for our large family. However, within the first year, we found one major issue.

Unusable Rooms

In the summer months, the western facing side of the house became incredibly hot. Unfortunately, this was the side where the large open kitchen and family room were downstairs. We combated that with heavy curtains and blinds to block out the sun from the glass doors and multiple windows. It helped, and when we kept the AC on constantly, it was livable. Dark and somewhat depressing, but livable.

The upstairs was another matter altogether. The kid’s bedrooms were fine. However, the master suite took up the entire west-facing wall with multiple windows in both the bedroom and a huge glass block window in the attached master bath. No matter what we tried, the master suite was always several degrees hotter than the rest of the house. And the bathroom, let’s just say the phrase “like a sauna” was very appropriate.

Insulation and AirFlow

I wish I had known then what I know now about insulation and airflow and how we could have reclaimed those rooms to make them more comfortable. The rest of the year, they were bright open rooms and a relaxing place to be. But, the summer when we should have enjoyed the light openness the most, they were either too hot to enjoy or so dark and depressing you didn’t want to stay in there.

Are there rooms in your house that just aren’t comfortable? Are they too hot in the summer or too cold in the winter? There are several reasons why rooms can vary in temperature. Those can range from insulation issues, the type and number of windows or doors, air leaks around fixtures, the placement of the room, and if walls are in the sun or in the shade.

There are things that can be done to alleviate temperature differences. One is to ensure your air ducts are clean and the vents and air returns are not being blocked by furniture. Having clean air filters and regularly changing them will also affect the performance of your AC unit and keep it running better longer.

Seal Air Leaks to Increase Energy Efficiency

Another is to seal air leaks. We’ve discussed in previous posts the importance of creating an air seal to help with the energy efficiency in your home. But it also helps with temperature regulation.

When you have air leaks, the conditioned air you are spending your hard-earned money on is going out, while the warmer outside air is sneaking in, causing your AC to work harder. Those leaks can be around windows that aren’t energy-efficient or need more caulking. Or doors that need new weather stripping.

Where Can I Find Air Leaks?

Sealing around fixtures in the attic and even reinsulating the attic altogether are some other suggestions. In a room like my old master bedroom with all the beautiful recessed lighting, those fixtures went right up into the extra-hot attic. And that air was no doubt making its way into my bedroom. Air is even leaking through the walls. As outside walls heat up the heat transfer through the siding and onto the sheathing and studs heats up the cavity where your insulation is. The older the insulation, the more it has settled or is breaking down. The more the air in those cavities is heating up and then exchanging with the cooler air in your home through any crack, nail hole, or outlet. Sealing those points can help.

As we found with our old house, adding drapes, shutters, or blinds to rooms with many windows can also help keep the temperature more even as it cuts down the greenhouse effect. However, if you don’t want to feel like you’re living in a cave, and keeping the natural light is important, installing window inserts can help with the air sealing and cut down on the heat being trapped inside.

Installing Foam Insulation Is Simple

One of the best ways we’ve found to fix the temperature differences is to simply reinsulate your home. Simple, you might ask? Yes, with Retrofoam injection foam you can air-seal and insulate your home all in one. RetroFoam is injected into each stud cavity, completely filling the space and sealing any crack or crevice, eliminating air movement and leaks. Even if your walls have insulation, RetroFoam can be installed without having to tear apart walls. One of our recent customers commented that they keep their thermostat set at 72 degrees and their children’s rooms were always hot. The evening after having Retrofoam installed, the temperature in the house dropped to 70 degrees for the first time ever. One child even asked for an extra blanket. The entire home now stays at the same temperature.

You’re paying for your whole house; let us see what we can do to reclaim your square footage and make it all livable again. Our project managers would be happy to talk to you and help find solutions for your home.
