Upgrading insulation can make your home more energy-efficient, which is an attractive selling point for potential buyers. Buyers are increasingly looking for homes that are energy-efficient and environmentally friendly. A well-insulated home can command a higher resale price.
How to Upgrade Your Home’s Insulation During Renovations
Upgrading insulation is an essential part of any renovation project. Whether you’re upgrading outdated insulation or adding insulation to areas that lack it, there are several strategies you can use to improve your home’s insulation during renovations.
1. Assess Your Current Insulation
Before you begin upgrading your insulation, it’s important to assess the current state of your home’s insulation. You can do this by:
- Inspecting your attic: Many homes, especially older ones, lack adequate attic insulation. Check if your attic has enough insulation and whether it has been damaged by moisture or pests.
- Looking for drafts: Feel around windows, doors, and walls for drafts. These are areas where heat is escaping and where insulation might be insufficient.
- Checking insulation in walls and floors: If you’re renovating specific rooms or floors, inspect the insulation in the walls, floors, and ceiling. If insulation is absent or inadequate, this is an opportunity to add or replace it.
- Consulting a professional: An energy audit by a professional can help pinpoint areas in your home that require insulation upgrades. They may use infrared cameras to detect energy leaks and suggest where improvements can be made.
2. Choosing the Right Insulation Material
There are several types of insulation materials available, each with its own advantages and disadvantages. The choice of insulation will depend on the area of the home you’re working on, the climate, and your budget. The following are some of the most commonly used insulation materials:
2.1. Fiberglass Insulation
Fiberglass is one of the most widely used insulation materials. It is relatively inexpensive, available in batt and roll forms for easy installation, and highly effective at reducing heat loss and gain. However, fiberglass insulation can irritate the skin and respiratory system, so it is important to wear protective gear when handling it.

- Cons: May settle over time and lose effectiveness, can irritate the skin and lungs.
2.2. Spray Foam Insulation
Spray foam insulation expands upon application, filling gaps and sealing leaks. It provides an airtight seal and is highly effective at preventing both heat transfer and air leaks. Spray foam insulation is typically more expensive than fiberglass, but it offers superior performance.
- Best for: Attics, crawlspaces, and areas with irregular shapes.
- Pros: Excellent air sealant, moisture-resistant, high R-value.
- Cons: Expensive, requires professional installation, may release harmful fumes during application.
2.3. Cellulose Insulation
Made from recycled paper products, cellulose insulation is an eco-friendly option that works well in walls and attics. It’s blown into place and offers good coverage. Cellulose is a good choice for retrofitting existing homes and filling gaps around electrical outlets, pipes, and wires.
- Best for: Attics, walls, and floors.
- Pros: Environmentally friendly, good soundproofing qualities, fills gaps well.
- Cons: Can settle over time, potentially more expensive than fiberglass.
2.4. Rigid Foam Insulation
Rigid foam boards come in various thicknesses and are used for insulating areas such as foundations, basements, and exterior walls. They provide excellent thermal resistance and are resistant to moisture. Rigid foam boards are lightweight, but they can be challenging to install in certain areas without professional help.
- Best for: Foundations, exterior walls, and basements.
- Pros: Moisture-resistant, excellent thermal resistance, lightweight.
- Cons: Expensive, difficult to install in certain areas.
2.5. Mineral Wool (Rock Wool) Insulation
Mineral wool, also known as rock wool, is a fire-resistant insulation material made from volcanic rock. It is highly effective in both soundproofing and thermal insulation. Mineral wool can be used in various areas, including attics, walls, and floors.
- Best for: Attics, walls, and floors.
- Pros: Fire-resistant, good soundproofing, moisture-resistant.

3. Areas to Focus on When Upgrading Insulation
The areas of your home that will benefit most from upgraded insulation are the ones that experience the greatest heat loss or gain. These areas include:
3.1. Attics
Attics are often one of the primary culprits when it comes to heat loss. If your attic isn’t properly insulated, heat can escape during the winter, and your home may become unbearably hot during the summer. Adding or upgrading insulation in the attic is a highly effective way to improve energy efficiency.
3.2. Walls
Many homes have insufficient insulation in the walls, particularly older homes built before modern insulation standards. If you’re planning to renovate or remodel a room, take the opportunity to add or upgrade the insulation in the walls. Blown-in cellulose or spray foam can be great options for insulating existing walls without needing to tear them down.
3.3. Floors
If your home has a crawlspace or uninsulated floors, this is an area that could benefit from additional insulation. Insulating floors helps prevent heat loss and reduces drafts that can make rooms feel uncomfortable.
3.4. Windows and Doors
Though not technically insulation, upgrading your windows and doors can have a significant impact on the energy efficiency of your home. Replacing old, single-pane windows with double-glazed or triple-glazed windows can reduce heat loss and improve comfort.
3.5. Basements
Basements are notorious for being cold and damp, and poor insulation in this area can contribute to higher heating bills. Insulating basement walls and floors can create a more comfortable living space while preventing heat from escaping.
