When it comes to renovating a home, one crucial consideration is the type of insulation used in the walls. With so many options available, it can be overwhelming for homeowners to decide which material will best suit their needs. In this article, we'll explore the different types of wall insulation and provide guidance on choosing the right one for your renovation.

Insulating plaster and lath walls is a complex process that requires careful consideration of several factors, including site conditions, budget, and installation requirements. According to Andre Desjarlais, director of a program at Oak Ridge National Laboratory in Tennessee that focuses on building better buildings, there's no simple answer when it comes to choosing the best type of wall insulation.

One key factor to consider is the R-value, which measures resistance to heat transfer. Different types of insulation have varying levels of efficiency, and some may be more suitable for certain applications than others. For example, Tom Silva, a general contractor on Season 28 of This Old House, chose to use a slow-pour version of foam insulation in living rooms and bedrooms, while opting for polyicynene in open areas such as kitchens, bathrooms, and attic stud bays.

Another important consideration is the skill level required for installation. Some types of insulation may require specialized equipment or training, which can add to the overall cost of the project. Homeowners should also think about the cost of materials and labor when choosing an insulation type.

In some cases, retrofitting new insulation into existing walls can be a challenge, especially if the walls are made of plaster and lath. In these situations, it may be necessary to use specialized techniques or products to ensure effective insulation without damaging the surrounding structure.

Ultimately, the best type of wall insulation for your home will depend on your specific needs and circumstances. By considering factors such as cost, efficiency, and installation requirements, you can make an informed decision about which material is right for your renovation project.

For homeowners who are looking to improve their home's energy efficiency, adding insulation to existing walls may be the single best way to reduce heating and cooling costs. According to Tom, a house with no insulation in its attic or roof can be particularly vulnerable to cold temperatures, making it essential to prioritize wall insulation in these areas.

In conclusion, insulating plaster and lath walls is a complex process that requires careful consideration of several factors. By choosing the right type of insulation for your project, you can ensure effective energy efficiency, comfort, and cost savings for years to come.
