Common Materials Used in Basement Insulation
One of the things you can do to find the best insulation material for your basement walls is to take a look at the most popular materials used and those that meet the Ontario building code. Some of the common materials used in basement insulation are:
- Foamboard
- Fiberglass
- Spray foam
You must, however, keep in mind that not every popular material will work for your basement. The material you select should be able to withstand the conditions in your home. This is why it is important to review each basement insulation option keenly. Take a moment to look at both the pros and cons of each recommended option and select the one that offers the most benefits.
Basements are often neglected spaces in the home because they are damp, cold, and sometimes a health hazard due to poor insulation. To deal with the insulation problems in your basement once and for all, you need to take time and find the best product. Insulation board suppliers usually recommend rigid foam insulation for basements.
There are several different options for rigid foam insulation. Let’s learn more about this product and find out if it’s an ideal option for your home.
Blanket Insulation (Fiberglass)
When trying to improve the energy efficiency of your building, one of the terms you will come across is blanket insulation. Blanket insulation is the most common type of rigid foam insulation. The basement insulation blanket is made of small fibres, mostly fibreglass. It is installed in spaces that don’t have many obstructions, such as unfinished walls, ceilings, and floors. The insulation can be fitted between studs, joists, and beams.
Banket insulation is preferred because of the following benefits:
- It is affordable
The basement insulation blankets are preferred not just for their energy efficiency but also for their affordability. When compared to other insulation materials, insulation blankets made of fibreglass are a great low-cost option. Moreover, the material is quite durable. It can serve you reliably for between 10 to 20 years, requiring minimal maintenance.
- Reduces your energy bills
Fiberglass insulation boasts a high R-value and thermal conductivity. This leads to lowered energy bills. The solution can reduce your heating and cooling bills by up to 50%.
- Improves the efficiency of your HVAC system
When there is a high energy loss, the HVAC system is forced to work harder. This often leads to high HVAC operating costs and an increased risk of HVAC damage. When fibreglass is installed on basement walls, you will notice a significant energy loss reduction. This means less strain on the HVAC. When you have the right basement insulation, you can get away with a smaller HVAC unit. The insulation enables you to keep the building more comfortable, irrespective of the time of year.
- Reduces noise pollution
Fiberglass insulation comes highly recommended because of its good acoustical properties. It can absorb and block sound waves, thus reducing the level of noise that passes through the ceiling or walls. Its density determines how much noise is blocked. Blanket basement insulation can thus be used to reduce noise between different floors and rooms in a building.
- It is eco-friendly
Fiberglass insulation is made using recycled glass. Moreover, once it is used, it can still be recycled instead of being disposed of. This helps conserve the environment. It is also good to note that most manufacturers use energy-efficient production methods which lower carbon emissions.
- It is mould and mildew-resistant
Fiberglass insulation is a natural mould-resistant material. However, you must remember that the material is fibrous, which means it can trap moisture and cause condensation issues. Buying faced insulation can help prevent this problem.
In addition to homes, blanket insulation is used in commercial and industrial buildings. In areas with warmer climates, the solution is used to supplement the radiant barrier in the walls and ceiling. This combination not only enables the roof to reflect heat but also keeps more heat from getting into your home.
In general, fibreglass is a commonly used insulation material in most homes because of its low cost. Rigid foam insulation is a better alternative, although it happens to cost a lot more than fibreglass. If you don’t have any major moisture concerns in your basement or your budget is extremely limited, fibreglass is an ideal option.
If you are interested in blanket basement insulation, contact Bernardi Building Supply as your first choice. The company not only supplies the best insulation supplies but will also help you pick the right materials that will help your family save money and stay comfortable even in the harshest winter and summer conditions.
Why XPS (Rigid Foam Board Insulation)?
XPS insulation, also known as extruded polystyrene, is another common type of rigid foam board insulation. The insulation is very popular in both residential and commercial basement insulation. It is available in different thicknesses to suit specific needs.
Advantages of XPS
- High R-Value
The main reason extruded polystyrene comes highly recommended in exterior insulation is because of its high R-value. This insulation material provides you with a thermal capability of R-value 5 per inch of thickness. The high R-value makes this material a very effective insulator that reduces heat transfer through the roofs, walls, and floors. XPS will significantly improve energy efficiency in your basement.
In addition to the high R-value, it is good to note that XPS has a low thermal conductivity. This means its closed-cell structure reduces the flow of heat, thus improving thermal insulation. This property is quite important in areas with extreme temperatures.
- Moisture Resistance
Another property that makes XPS so effective is the fact that it is a closed-cell foam. This means it has a highly dense and closed structure. The closed-cell structure of the insulation panels helps resist moisture infiltration. XPS will not absorb water. This makes it ideal for basement walls where moisture resistance is crucial.
- Durable
XPS is quite durable mostly because it can withstand compression. This enables it to maintain its insulating properties for years. Moreover, the material is highly resistant to rot and other forms of deterioration.
- Offers Structural Support
Because XPS is a rigid material, it is a great option for applications where structural support is required. The material can be used as a sheathing in a basement wall system as well as under slabs where a strong and durable material is needed.
- Versatility
XPS is quite versatile and can be used in many applications, including inside basement walls, foundations, floors, and roofs. The material is also available in different thicknesses, and it can be cut easily to fit specific dimensions.
- Fire Resistance
When choosing a basement insulation material, you have to ensure that it satisfies the Ontario building code. XPS is resistant to ignition and doesn’t contribute to the spread of flames. This factor helps meet building code requirements for fire safety.
- Installing Insulation is Easy
The XPS boards are lightweight, easy to cut, and can be shaped to fit any space. The boards also come in different sizes, which makes them convenient to install.
Thanks to the many benefits offered, XPS is certainly more expensive than fiberglass insulation. There are other forms of insulation to consider, such as loose-fill. The major drawback with many of the other options is that they are not DIY-friendly. XPS is easy to install without much technical knowledge. It doesn’t require any special equipment; therefore, it’s not costly to install.
Basement Fiberglass Insulation
Fiberglass insulation is common for insulating basement walls and ceilings. This is because of its effectiveness and ease of installation. Moreover, compared to other basement insulation materials, fiberglass is more affordable.
Fiberglass consists of thin glass fibers often available in rolls and batts. Fiberglass insulation helps to slow the spread of cold, heat, and sound in buildings. The insulation makes a home cooler in the summer and warm in the winter.
The prime benefits of fiberglass basement insulation are:
- Easy Installation
Fiberglass insulation is available in batts or rolls. This is what makes fiberglass easy to install and suitable even for DIY basement renovation projects. It is, however, important to wear protective gloves and masks during installation to avoid skin irritation and respiratory problems. This is more so when working with foam compatible adhesive. Moreover, the insulation should be done snugly against the basement walls, leaving no gaps. A vapour barrier should also be used when necessary.
- Moisture Resistance
While fibreglass doesn’t absorb water, it can trap moisture. If your basement is prone to moisture issues, consider addressing moisture issues in the basement and installing a vapour barrier to prevent moisture infiltration.
- Fire Resistance
Fiberglass insulation is non-combustible. It doesn’t contribute to the spread of fire.
Spray Foam Insulation
We have cans of spray foam to fill any gaps under windows and doors. As you may already know, spray foam insulation is an insulation material that is applied as a liquid and expands into a foam. Spray foam offers excellent insulating properties thanks to its high R-value and its ability to seal cracks and gaps.
There are two main spray foam insulation types. The first is the open-cell foam. This has a lower R-value and is more cost-effective. It is less dense and has a spongy, tender feel.
Closed-cell foam is the second type of spray foam insulation. It has a higher R-value and is more rigid. It is preferred on a basement wall because it creates superior moisture and air barriers.
Spray foam insulation can be used for:
- Creating an airtight barrier in the basement walls
- Insulating crawl spaces and areas that are hard to reach
- Soundproofing because of its ability to expand and fill gaps
- Sealing gaps between panels to prevent air leakage
- Insulating HVAC ducts to improve energy efficiency
Although spray foam insulation offers numerous benefits, it is advisable to consult with insulation experts to determine the best type and application method for your specific crawl space, basement ceiling, or walls. This is because the proper installation of spray foam is the key to ensuring optimal performance and safety. You also need to consider the local building codes more so when it comes to the R-values.
Benefits Of Rigid Foam Insulation
Foam board insulation comprises panels that consist of polyurethane, polystyrene, or polyisocyanurate. Foam board insulations come in different lengths, thicknesses, and facings. Foam board insulation reduces heat conduction through structural elements like steel studs and wood. It also provides excellent thermal resistance.
The benefits of foam board insulation are:
- High R-Value
Foam board insulation offers high thermal resistance per inch of thickness. This enables it to resist the flow of heat effectively. Consequently, the insulation option enables you to maintain a comfortable indoor temperature and reduce energy consumption. Moreover, it is good to note that when it is properly installed, the rigid foam board installation creates an air barrier that prevents air leakage.
- Durability
Most foam board materials are durable and do not require replacement. The material can withstand wear and tear. Its durability further means that minimal maintenance is needed.
- Lightweight
When compared to other insulation materials, foam board is very lightweight. This makes it easy to handle, transport, and install, thus reducing labour and installation costs.
- Moisture Resistance
Some rigid foam board products are water-resistant and help prevent mildew and moisture build-up. XPS and polyisocyanurate have closed-cell structures, which make them highly resistant to moisture absorption. This prevents issues related to water damage and mould growth.
Basements are usually highly susceptible to water. The insulation material installed in your basement must do a good job of preventing moisture penetration. The best part about rigid foam insulation is that it is water-resistant. Unlike other insulation materials like fiberglass which holds water over time and creates mold, XPS helps to resolve moisture issues in the basement. Even though the drywall in your basement can still hold water, you should be able to see it and take action before it spreads.
The Installation Process
The best thing about rigid foam insulation such as XPS is that it can be applied on painted walls. You just need to make sure you perform the required treatments, such as applying basement waterproofing paint before insulating the walls. Moreover, before the installation is done, you need to ensure that you have a clean and dry surface.
Before you get started with the installation, gather all the tools required for the job. You’ll need a foam board adhesive, a drywall saw, and a caulk gun to install the rigid foam insulation. Here is a list of the key materials and tools you will need:
- Rigid insulation products
- Foam compatible adhesive
- Foam sealant or caulk
- Utility knife or saw for cutting the panels
- T-square or straightedge
- Construction adhesive gun
- Measuring tape
- Fasteners
- Protective gear
Once the required materials are ready, you can go ahead and get started with the installation. Always make sure that you comply with the local building codes.
- Prepare the Surface
For a perfect installation inside basement walls, start by making sure the wall surface is clean, dry, and free of debris. Get rid of cobwebs on the walls. It is also important to handle any repairs of damaged areas and address moisture problems before installing insulation.
- Measure and Cut the Panels
The next thing you need to do is measure the dimensions of the basement wall to determine the size of the panels you will need. If you plan on insulating the basement ceiling and floors, you should get the measurements, too. You can use the T-square to mark the dimensions on foam board insulation and cut to the desired size using your saw or utility knife.
- Apply Adhesive
You now need to apply adhesive to the back of the panels and attach them firmly to the basement walls. Start from one corner and work your way across the wall.
- Secure the Panels to the Wall
Depending on the local building codes and the application method, you may have to secure the panels firmly using nails or screws. Use the fasteners at the recommended intervals.
- Seal the Edges and Joints
To create an air barrier in basement insulation, you need to use caulk or spray foam to seal the seams or joints between the panels. Pay attention to the edges and corners to achieve a continuous air seal.
If you go the DIY route, it is important to follow the manufacturer’s guidelines and recommendations for the specific spray foam and rigid foam insulation product you are using. Moreover, you have to adhere to the Ontario building code. If you are not experienced with insulation installation, consult a professional installer to ensure an effective installation.
Application Tips For Rigid Foam
- Use the adhesive liberally making sure you’ve covered the corners and along the edges.
- As you wait for the adhesive to cure, use something to hold the boards firmly in place against the wall.
- To ensure that all areas are covered, install full pieces, and after the adhesive is cured, you can use a drywall saw to cut the openings.
- Make sure the seams are tight enough to prevent air from entering or escaping through the insulation.
- Use tapes across the joints when you finish applying the insulation. If there are larger gaps remaining, you can use expandable foam to fill them up.
