What is Fiberglass Roll Insulation?

Fiberglass roll insulation is a type of thermal and acoustic barrier made from fine glass fibers. It is commonly available in pre-cut rolls or continuous lengths and is designed to be rolled out between framing in walls, floors, and ceilings. Ideal for both residential and commercial projects, it is one of the most widely used insulation types due to its affordability, ease of installation, and reliable performance.

Types of Fibreglass Rolls

1. Faced Fiberglass Rolls

Faced fiberglass rolls come with a layer of kraft paper or foil attached to one side, acting as a built-in vapor barrier. This facing helps prevent moisture from penetrating the insulation, making it ideal for use in exterior walls, lofts, attics, and crawl spaces where humidity control is essential. The facing also makes installation easier, as it can be stapled directly to wall studs or ceiling joists. If you’re working in an area prone to condensation or want to meet building code moisture requirements, faced rolls are a practical and reliable choice.

2. Unfaced Fiberglass Rolls

Unfaced fiberglass rolls are insulation products without any attached vapor retarder. These rolls offer flexibility in use, making them suitable for interior walls, soundproofing between rooms, or layering with other insulation types. They are commonly used in renovations or retrofits, especially when additional insulation is needed but vapor control is not. Because of their open surface, unfaced rolls are also breathable, reducing the risk of trapped moisture in certain wall constructions. This type is ideal for spaces where moisture is not a concern but thermal and acoustic performance is needed.

3. Chopped Strand Mat Rolls

Chopped strand mat rolls are constructed from randomly distributed short fiberglass strands held together with a binder. These mats are commonly used in composite applications such as boat building, automotive panels, or flat roofing, where they are combined with resin to form rigid laminates. Their uniform strength in all directions makes them excellent for reinforcing curved surfaces and complex molds. Chopped strand mats are easy to cut and layer, offering versatility for custom reinforcement projects and structural repairs where strength and flexibility are both important.

4. Fiberglass Cloth / Fabric Rolls

Fiberglass cloth or fabric rolls are tightly woven for maximum durability and are primarily used in industrial, marine, and automotive applications. These fabrics provide excellent strength-to-weight ratios, making them ideal for reinforcing surfaces or creating lightweight but strong structures. When combined with epoxy or polyester resins, fiberglass fabric forms a durable, weather-resistant finish suitable for boat hulls, tanks, or insulation panels. Their resistance to high temperatures, moisture, and chemicals also makes them valuable in demanding environments where traditional insulation would degrade.

Key Benefits of Fiberglass Roll Insulation

• Excellent Thermal Resistance: Fiberglass rolls help maintain consistent indoor temperatures by reducing heat transfer, making your home or building more energy-efficient.
• Cost-Effective Solution: Compared to other insulation materials, fiberglass roll insulation is affordable while still delivering reliable results.
• Acoustic Insulation: It dampens sound between rooms and from external sources, creating a quieter and more comfortable indoor environment.
• Fire-Resistant: As a non-combustible material, fiberglass adds an extra layer of safety to your property.
• Moisture and Mould Resistant: Faced rolls provide a vapor barrier, reducing the risk of damp and mold in vulnerable areas.

• Easy to Install: Lightweight and flexible, fiberglass rolls can be cut to size and fit snugly between joists and studs, making them perfect for DIY and professional installs.

   

Fiberglass Roll Selection Guide

Choosing the right fiberglass roll is essential for effective insulation, reinforcement, and long-term performance. Use this guide to help select the best product for your project:

• R-Value: Select a roll with the appropriate thermal rating. Higher R-values provide better protection in colder climates, especially for attics and exterior walls.
• Faced vs. Unfaced Rolls: Faced rolls include a vapor retarder – ideal for moisture-prone areas. Unfaced rolls offer flexible use in layered or interior applications.
• Width & Coverage: Make sure to check the width of each roll to match your stud spacing (typically 15" or 23"). This ensures a clean fit with less trimming.
• Reinforcement Applications: For composite or resin-based builds, look for chopped strand or mat options. These are perfect for pairing with resin in waterproofing or fabric lamination projects.
• Fiberglass Fabric Type: If your project involves fiberglass cloth or fiberglass fabric, ensure compatibility with your structural needs, especially in marine, roofing, or industrial applications.
• Fire & Moisture Resistance: Fiberglass is naturally fire-resistant and works well in damp spaces, offering added protection and durability.

• Trusted Tools & Accessories: Don’t forget to add essential tools, a mat, and reinforcing accessories to your cart for a complete setup.

   

Common Applications of Fiberglass Roll

Fiberglass roll insulation is incredibly versatile. Here’s where it performs best:

• Wall & Ceiling Insulation – Insulate interior or exterior walls using wide-format rolls for fewer seams.
• Resin-Based Projects – Combine with resin to reinforce laminates or structural panels.
• Chopped Strand Reinforcement – Use in layered composite builds needing higher tensile strength.
• Fabric-Laminating – Ideal for bonding with fabrics, mats, and tools in specialist builds.

• Waterproofing Systems – Enhance durability and moisture protection in wet-prone areas.

   

What Makes Our Fiberglass Rolls Different?

• Premium Materials: Crafted from durable fiberglass fabric and available in multiple width options to suit various wall and ceiling cavities.
• Resin-Compatible: Perfect for pairing with resin systems in composite reinforcement applications like marine builds or waterproofing.
• Versatile Use: Use as part of your general reinforcement strategy or for projects requiring chopped strand and mat layers for added durability.

• Multi-Functional: Provides excellent thermal insulation, noise control, and protection against fire and moisture.
