Mineral wool insulation is suitable for residential, retail, commercial office spaces, and institutional buildings.
Loose Fill Insulation
Loose fill insulation is made up of loose fibers or fiber pellets. The insulation is blown into building cavities much like shooting water from a hose. It can be more costly than other types of insulation, but it can get blown into corners and places where a blanket might not fit. It can also be installed without disturbing frames or finishes.
Loose fill insulation consists of small particles of fiber, foam, or other materials. These small particles form an insulation material that can conform to any space without disturbing structures or finishes. This ability to conform makes loose fill insulation well suited for retrofits and locations where it would be difficult to install other types of insulation.
For commercial spaces aiming to lower energy bills, loose fill insulation can easily fit into irregular spaces or around obstructions, ensuring a tight seal.
Spray Foam Insulation
Spray foam insulation is a liquid that turns into foam when sprayed. It expands to fill gaps and creates an airtight seal. Its insulating value is excellent, usually between R-6 to R-7 per inch. This type of insulation offers a superior air and thermal barrier.
Benefits
- Expands to fill gaps
- Creates an airtight seal
- High R-value per inch
Application
Spray foam is applied as a liquid and then expands. It can be used in walls, attics, and under floors. The goal is to achieve a consistent texture rather than an ultra-smooth finish. The foam should be evenly applied without gaps.
Considerations
- Can be expensive
- Needs to be applied by professionals
- Must be covered by sheetrock or metal as it’s flammable
Spray foam insulation is great for creating an airtight seal and filling gaps, making it a top choice for many retail spaces.
Rigid Foam Insulation
Rigid foam insulation is a dense, solid material that offers high thermal resistance due to its low thermal conductivity. Insulating values vary by type (e.g., XPS, EPS, or polyiso) but typically range from R-4 to R-8 per inch. It’s known for its effectiveness in controlling heat transfer.
Types of Rigid Foam Insulation
- Extruded Polystyrene (XPS): XPS is R5/inch, but it will be R5/inch no matter if it’s 50 below or 500 years from now. It does not degrade. You need to air seal with tape or caulking at all the seams and fill gaps with foam in a can. Again, foam needs to be covered with sheetrock or metal because it is flammable.
- Expanded Polystyrene (EPS): EPS is a lightweight material that offers good thermal resistance. It is often used in walls and roofs.
- Polyisocyanurate (Polyiso): Polyiso has the highest R-value per inch of thickness among rigid foam insulations. It is often used in commercial buildings.
Applications of Rigid Foam Insulation
- Basement Walls: For basement walls, a thicker foam board is often recommended because of its high moisture environment and the need for greater energy retention.
- Roofs: Rigid foam is commonly used in flat roofs to provide a continuous layer of insulation.
- Exterior Walls: It can be applied to the exterior of buildings to improve thermal performance.
Rigid foam panels are good for any climate, withstanding even the highest of temperatures. They are effective for dampening noise as well as resisting heat and moisture.
Fiberglass Insulation
Fiberglass insulation is made from tiny glass fibers and is available in batts, rolls, or loose-fill forms. It’s one of the most cost-effective options for insulating retail spaces. This type of insulation is known for its fire resistance and ease of installation. It provides good thermal insulation due to its low thermal conductivity, with typical R-values ranging from R-11 to R-38, depending on thickness and density.
Fiberglass insulation also has significant recycled content, with some products containing up to 80 percent recycled glass. The other main ingredient, silica sand, is a naturally renewing resource, which helps limit environmental impact during manufacturing.
However, fiberglass is not impervious to water. If exposed to moisture, it will lose its effectiveness. To prevent this, facing materials are often laminated to rolls or batts of fiberglass to act as a vapor barrier or vapor retarder, protecting the insulation from moisture.
Fiberglass insulation has been on the market for over 70 years, making it a reliable choice with a proven track record.
Here are some key points to consider:
- Available in batts, rolls, or loose-fill forms
- Cost-effective and easy to install
- Fire-resistant
- Typical R-values range from R-11 to R-38
- Contains up to 80% recycled glass
- Requires vapor barrier to protect from moisture
Reflective Insulation
Reflective insulation is a unique type of insulation that works by reflecting heat rather than absorbing it. This makes it especially useful in hot climates where keeping the heat out is a priority. Reflective insulation can also deflect radiant heat, particularly in attics, to further reduce cooling demands in warm climates.
Reflective insulation is typically installed in attics, under roofs, or in walls. Its primary function is to reduce radiant heat transfer, which helps maintain cooler indoor temperatures. While it doesn’t have a traditional R-value, it enhances energy efficiency by reflecting heat radiation.
- Reflects radiant heat away from living spaces
- More effective in hot climates
- Can lower cooling costs by 5% to 10%
Using reflective insulation can make a big difference in maintaining a comfortable environment, reducing energy costs, and ensuring longevity of your commercial property.
Cellulose Insulation
Cellulose insulation is made from recycled paper treated with fire retardants. It offers good thermal insulation, with an R-value typically ranging from R-3.2 to R-3.8 per inch. This makes it an effective choice for energy efficiency when installed properly.
Benefits
- Eco-friendly: Made from recycled materials, contributing to sustainable building design.
- Air quality: Helps minimize air leakage, preventing outdoor pollutants and allergens from entering the building.
