Types of Home Insulation
Fiberglass Insulation
Advantages:
Widely available and relatively inexpensive.
Easy to install in standard wall cavities, attics, and floors.
Non-combustible and does not settle over time when properly installed.
Disadvantages:
Can irritate skin, eyes, and respiratory system during installation.
Not as effective in blocking air infiltration compared to other types.
Requires protective clothing and gear during installation due to glass fibers.
Cellulose Insulation
Advantages:
Made from recycled paper products, environmentally friendly.
Good thermal performance and effective at reducing air infiltration.
Fire retardant additives improve fire resistance.
Disadvantages:
May settle over time, reducing effectiveness unless properly installed.
Can absorb moisture, leading to mold or mildew if not adequately protected.
Requires specialized equipment and training for proper installation.
Spray Foam Insulation
Advantages:
Provides excellent thermal resistance and air sealing properties.
Expands to fill gaps, cracks, and irregular spaces, creating a seamless barrier.
Can improve structural integrity and noise reduction.
Disadvantages:
More expensive than other types of insulation.
Installation requires professional expertise and specialized equipment.
Some formulations can off-gas chemicals during installation, requiring proper ventilation.
Rigid Foam Insulation
Advantages:
High R-value per inch, providing superior thermal resistance.
Resistant to moisture, insects, and rot, making it suitable for below-grade applications.
Lightweight, durable, and easy to cut for custom fitting.
Disadvantages:
More expensive than fiberglass or cellulose insulation.
May require additional fire protection in certain applications.
Can be challenging to retrofit in existing walls due to its rigidity.
Mineral Wool Insulation
Advantages:
Excellent fire resistance and thermal performance.
Water repellent and does not promote mold or mildew growth.
Good sound absorption properties, improving acoustic insulation.
Disadvantages:
Can be more expensive than fiberglass insulation.
Heavier and denser than other types, requiring proper support during installation.
May cause skin irritation, so protective clothing is recommended during installation.
Reflective Insulation
Advantages:
Effectively blocks radiant heat transfer, especially in hot climates.
Lightweight and easy to install, typically in attics or under roofs.
May improve energy efficiency when used in combination with other insulation types.
Disadvantages:
Less effective in colder climates where radiant heat transfer is less significant.
Relies on air gaps to provide thermal resistance, so installation must be precise.
Limited effectiveness as a standalone insulation in regions with significant temperature fluctuations.
Each type of insulation has its own set of advantages and disadvantages, so it's essential to consider factors such as climate, budget, and installation requirements when choosing the right insulation for your home.
