What Is Retrofit Insulation?
Retrofit insulation—sometimes called re-insulation—is the process of adding new insulation to an existing home or building. Unlike new construction insulation, which is installed while a structure is being built, retrofit insulation is designed to improve insulation performance in homes that are already finished and occupied.
Many older homes were built with little to no insulation, or with materials that no longer perform well. In other cases, insulation may have been installed incorrectly or has settled over time, leaving gaps that allow heat loss and air leakage. Retrofit insulation corrects these issues and restores your home’s thermal efficiency.
Insulation Solutions for Existing Homes
If your home was built in the 1970s or earlier, there’s a strong chance it doesn’t have enough insulation by today’s standards. Even newer homes can benefit from retrofit insulation if the original installation was inadequate.
You may want to consider retrofit insulation if you notice:
- Rising energy bills
- Drafty rooms or cold and hot spots
- Uneven temperatures throughout the home
- Rooms that are difficult to heat or cool
While these are common signs, the best way to know for sure is with a professional insulation evaluation.
Retrofit Insulation Materials We Use
Retrofit insulation uses many of the same materials as new construction insulation. The best option for your home depends on factors such as your attic type, wall construction, HVAC system, and overall energy goals.
OJ Insulation offers retrofit installation using:
- Cellulose insulation
- Fiberglass insulation
- Spray foam insulation
- Radiant barrier insulation
In many cases, a combination of insulation types provides the best results. For example, radiant barrier insulation may be installed in the attic to reduce radiant heat, while cellulose or fiberglass is added to walls or attic floors for thermal resistance.
Our team will recommend the most effective solution based on your home’s specific needs.
Retrofit Insulation & Superinsulation
In some cases, retrofit insulation can be part of a superinsulation approach. Superinsulation focuses on dramatically reducing heat loss and heat gain by combining higher insulation levels with improved air sealing.
This approach can significantly improve indoor comfort, reduce energy usage, and lower long-term utility costs. Professional installation is essential to ensure materials are installed correctly and meet local building codes and regulations.
