Category: Spray Foam Insulation

Are you wondering why your basement smells different from the rest of your home? It might be because it’s not properly insulated. An uninsulated basement can lead to higher utility costs and condensation from air leaks. Poor insulation can also mean that your basement won’t stay cool during the next summer heat wave, leaving you with no cool place to escape the heat.

If you want to make your basement more comfortable and energy-efficient, spray foam insulation could be the answer. In this guide, we’ll explore the benefits of using spray foam insulation for your basement walls, address common concerns, and provide tips on preparing your basement for insulation.

Is Installing Spray Foam Insulation in My Basement Worth It?

When it comes to insulating your basement, traditional batting insulation requires a perfect vapour and air barrier to prevent moisture from seeping into the walls. Over time, you may find that your basement has taken on a musty scent from poor insulation and condensation. 

However, spray foam insulation is impermeable, isolating warm indoor air from the cold exterior walls. This makes it a superior choice for maintaining a consistent temperature in your basement.

Benefits of Spray Foam Insulation

• Long-term Energy Savings: Spray foam insulation reduces HVAC energy consumption and helps eliminate thermal bridging, resulting in more consistent temperatures throughout your home and lower energy bills.
• Increased Property Value: Spray foam insulation can increase your property’s value, making it a worthwhile investment for new and existing basement walls.
• Long-lasting Performance and Durability: Unlike traditional insulation materials, spray foam does not sag or lose shape over time, ensuring long-lasting performance and better indoor air quality.
• Versatile Use: Spray foam can provide comprehensive insulation on basement walls, ceilings, and around the rim joists.
• Water Resistance: Spray foam is water-resistant and helps reduce condensation, maintaining better indoor air quality and avoiding potential moisture buildup issues before they begin.
• High R-Value: Spray foam insulation has a high R-value, providing superior thermal resistance and enhancing overall home comfort.

Although spray foam insulation costs more upfront, it pays off with long-term energy savings and added home value.

Will Spray Foam Insulation Stop Water Leaks in the Basement?

It’s important to note that spray foam insulation is not a solution for existing water leaks. You need to repair any leaks before installing spray foam. Once leaks are fixed, spray foam can help keep out moisture from condensation, but it won’t stop a significant water flow.

How Do You Prep a Basement for Spray Foam Insulation?

Proper preparation is crucial for successfully installing spray foam insulation in your basement. To help you better prepare, follow along with our team at Thermo Solutions’ spray foam insulation process:

1. Assessment: At Thermo Solutions, we believe in a collaborative approach, working closely with homeowners to ensure the best results. Once the basement walls are bare, our team will do an evaluation to determine the best approach to insulating your basement, including insulating around your electrical system. Before we begin, keep an eye out for any potential water damage that will need to be addressed before installing spray foam insulation.
2. Preparation: All windows, doors, and outlets must be prepped to prevent the foam from seeping into unwanted areas.
3. Application: Spray foam is applied around rim joists and concrete block walls before installing drywall. This method ensures the foam can get behind the studs to prevent thermal bridging.

Find the Best Time to Install Spray Foam

The ideal time to install spray foam insulation is when you’re working on an unfinished basement or completing a basement renovation. Once the framing is complete, the spray foam can be applied to maximize floor space for the finished product. It can be challenging to spray after the walls are built due to access issues with the joists.

Are your utility bills skyrocketing with the weather, or is there no rest from noise pollution, making being in your home uncomfortable? Amidst rising utility costs in Alberta, choosing the right insulation during renovations can be a game-changer. Spray foam insulation not only cuts down on energy expenses but also helps create a quieter, more serene living space. Here’s what to know about spray foam insulation installations in your home.

Can You Use Spray Foam Insulation Around Electrical Boxes?

You can safely use spray foam insulation around electrical wires and boxes, but it isn’t something to try without training. Preparation is everything! Before you begin, know the type of wiring you’re possibly coming in contact with and prep any boxes and panels so the foam cannot enter and be next to connections. 

Generally speaking, wiring is safe to be in contact with, except in instances with very old knob and tube wiring. If you’re not sure what wiring your home has, ask us! Properly applied spray foam insulation provides an airtight seal, improving your home’s energy efficiency by preventing air leaks and drafts. Closed-cell spray foam insulation application should consider the following:

• Create a Seal: Spray foam creates an effective seal to prevent air leaks, enhancing energy efficiency and maintaining consistent indoor temperatures.
• Accessibility: Always leave access to junction boxes. Do not spray overtop fixtures that are not rated for direct contact. We recommend going a step further since spray foam is a liquid applied. It is far safer to create a barrier overtop of fixtures, such as pot lights, prior to spraying.
• Application: Spray around the electrical box, not inside, and avoid overfilling to prevent unwanted pressure. This ensures that the electrical connections remain secure and accessible.
• Building Codes: Always check local codes and consider pre-inspections to check for any existing wiring issues. Compliance with regulations ensures safety and reliability.

1/2lb spray foam insulation can also be an air barrier for your home, protecting your electrical system and home, while also acting helping with noise pollution.

Can You Leave Spray Foam Insulation Exposed?

In many cases, spray foam insulation should be covered by a thermal barrier, such as a spray-on thermal barrier, mineral wool or drywall. This is key for protecting your and your family’s safety in a fire, as it provides more time to evacuate. Always check with your local jurisdictional requirements, or ask the experts! As you plan, consider where the spray foam will be applied:

• Living Spaces: If the insulation is in living areas or storage spaces, it should be covered. This can include warm crawlspaces or attics designed to supply the home with plumbing and heat. It’s essential to understand the difference. You must also protect the foam from areas next to air returns. Should there be a fire, it’s code to allow more time before harmful smoke can be pulled back into the furnace and redistributed throughout the home.
• Cold Attics and Crawl Spaces: These areas often don’t require covering, but it’s always best to check local regulations. Exposed foam in these non-living areas is typically acceptable.

If you’re looking for a second opinion, our spray foam experts are here to help answer any questions you have and find the areas in your home where the heat is escaping before we begin.

Can You Spray Foam Insulation Over Electrical Wires?

Yes, spray foam insulation can be used over electrical wires, but keep these considerations in mind:

• Type of Foam: Closed-cell foam is used for better insulation and rigidity, and open-cell foam is used for flexibility. Closed-cell foam is denser and provides a higher R-value, while open-cell foam is softer and better for filling nooks and crannies.
• Future Access: Think about future accessibility for repairs. Encasing wires can make future work more challenging.
• Code Compliance: Always follow local building codes. This ensures that your installation meets all safety standards.
• Professional Installation: Hiring professionals ensures a safe and proper application. Expert installers know the best practices to avoid damaging the wires.

How Many Inches of Spray Foam Insulation Do I Need?

The thickness of spray foam insulation depends on the area of application, Alberta code requirements, and your insulating goals:

• Walls: 2-4 inches of closed-cell foam is typically sufficient for walls, providing excellent thermal resistance and structural support.
• Roof Deck: 4-7 inches for optimal insulation. This thickness helps protect against heat loss in winter and heat gain in summer.

Spray foam insulation has a long lifespan, as it doesn’t sag or break over time, providing a durable and long-lasting solution for your home. A professional assessment will help determine the right amount for your home’s needs.
