Insulation Boards vs. Rolls: Which is Better?
The debate over whether insulation boards or rolls are superior has long been a topic of discussion. Both options offer their own unique benefits, so it ultimately comes down to personal preference and specific needs.
Insulation boards are often favored for their durability and ability to provide a higher R-value per inch of thickness. This means that they can effectively reduce heat transfer and improve energy efficiency. Additionally, insulation boards are known for their ease of installation, as they can be easily cut to fit any space.
On the other hand, insulation rolls are preferred for their versatility and cost-effectiveness. They are available in various sizes and thicknesses, making them suitable for different applications. Insulation rolls are also beneficial for covering larger areas quickly and efficiently.
When deciding between insulation boards and rolls, it’s important to consider factors such as the desired R-value, ease of installation, and specific project requirements. Additionally, it can be helpful to consult with a professional to ensure that the chosen insulation method is the most suitable for the specific application.
In conclusion, both insulation boards and rolls have their own advantages, and the choice ultimately depends on individual needs and preferences. Whether it’s durability and efficiency with insulation boards, or versatility and cost-effectiveness with rolls, there is no definitive answer.
Insulation boards offer higher R-value than roll insulation. They are versatile and can be used inside and outside buildings. Roll insulation is less expensive and requires less time and precision to install.
Both products provide good insulation when used in the right situations. Homeowner choice depends on budget, space, area, and preferred R-value.
Insulation rolls, also known as blanket insulation, insulate stud, joist, and rafter cavities, as well as attic floors. Some rolled insulation has a vapor barrier. The most popular type is fiberglass, but other options include mineral wool and sheep wool rolls. Fiberglass rolls are inexpensive and widely available, with an approximate R-value of 3.5 per inch.
Mineral wool rolls have an R-value of 3.2 per inch and provide excellent soundproofing. Sheep wool rolls, with an R-value of 4.3 per inch, are all-natural but more expensive.
Pros:
– Blanket insulation–rolls or batts–is the most commonly used type of insulation, with fiberglass being the dominant material.
– Inexpensive: Fiberglass is the most affordable insulation option.
– Easy installation: It is a simple and quick DIY project.
– Designed for cavities: Manufactured to fit stud cavities with various thicknesses available.
– Flexible: Easy to cut and fit around obstructions.
Cons:
– Moisture absorption: Fiberglass insulation absorbs moisture and loses its insulation value when wet.
– Non-compressible: Its R-value decreases when compressed.
– Health risks: Fiberglass can cause itchiness and respiratory problems when its fibers are inhaled.
Rigid insulation boards insulate all parts of buildings, including basement and above-grade walls, attics, and roofs. They are available in different sizes and thicknesses and are moisture resistant but flammable, so they need to be covered with non-combustible material like drywall. The three main types of insulation boards are Expanded Polystyrene (EPS) with an R-value of approximately 3.8 to 4.2 per inch, Extruded Polystyrene (XPS) with an R-value of approximately 5.0 per inch, and Polyisocyanurate (ISO, PIR) with an R-value of approximately 6.5 per inch.
Insulation boards are versatile and offer excellent R-values for the money invested. They have better R-values than most roll insulation. They are moisture resistant and do not require a vapor barrier. Installation is easy and safe.
Additionally, they require less floor space due to higher R-values. However, the cost is the biggest difference between insulation boards and rolls. Insulation boards are expensive, costing twice as much as fiberglass.
They are also combustible and must be covered with a non-combustible product. Installation can be time-consuming.
When choosing insulation, consider its versatility, excellent R-values, and moisture resistance. Take into account the cost, as insulation boards are more expensive. Also, keep in mind that installation can be time-consuming.
If cost and time are important, roll insulation is a valid option. Both products meet code standards. Northern codes may require higher R-values but not different insulation. Terry Schutz is a freelance writer specializing in home renovations, DIY advice, and construction.
