Protect Your R-value
Prodex Total is the perfect complement to fiberglass metal building insulation. Here's why:
R-value Protection
Fiberglass R-value comes from the air pockets between the fibers, not the fibers themselves. When moisture fills these air pockets, the R-value decreases.
How Prodex Total Helps
Installing Prodex Total (insulation + radiant barrier + vapor barrier + air barrier + condensation eliminator) between the fiberglass and metal sheeting helps keep the fiberglass dry, preserving the fiberglass R-value over time.Increased Energy Efficiency
When used in conduction with Prodex Total, you'll get the stated R-value performance from fiberglass. You'll also enjoy the benefits of Prodex Total: No condensation, increased R-value, and radiant barrier protection.

Introduction to Fiberglass Insulation for Metal Buildings and Pole Barns
When it comes to insulating metal buildings and pole barns, fiberglass insulation stands out as one of the most cost-effective and efficient solutions. These types of structures, often used for agricultural, industrial, and storage purposes, are particularly vulnerable to extreme temperature fluctuations and moisture issues. Proper insulation not only ensures comfort and energy efficiency but also protects the structural integrity of these buildings.
In this article, we’ll explore why fiberglass insulation is the ideal choice for metal buildings and pole barns and highlight the key benefits it offers for building owners and operators.
Why Choose Fiberglass Insulation for Metal Buildings and Pole Barns?
Fiberglass insulation is the go-to solution for insulating metal structures and pole barn buildings due to its versatility, affordability, and superior thermal performance. Its lightweight nature makes it easy to install on metal frames or within pole barn cavities, while its moisture and mold resistance ensures long-term durability. Additionally, fiberglass insulation is non-combustible, providing an added layer of safety for buildings used to store equipment, vehicles, or flammable materials.
Whether you’re constructing a new pole barn or retrofitting an existing metal building, fiberglass insulation delivers reliable performance in a variety of applications.
Benefits of Fiberglass Insulation for Metal Buildings and Pole Barns
1. Improved Temperature Control
Metal and pole barn buildings are highly conductive, making them prone to extreme temperature swings. Fiberglass insulation provides excellent thermal resistance (R-value), keeping interiors cooler during summer and warmer in winter. This consistent temperature regulation improves comfort and functionality.
2. Energy Efficiency
By minimizing heat transfer, fiberglass insulation reduces the energy demand for heating and cooling systems. This leads to lower energy bills and a more sustainable building. For property owners looking to enhance energy efficiency, fiberglass is an excellent choice.
3. Condensation Prevention
Metal buildings are particularly susceptible to condensation, which can lead to rust, corrosion, and water damage. Fiberglass insulation acts as a barrier, reducing moisture buildup and protecting the structural components of your building. Enhance this feature and protect your fiberglass from moisture by installing Prodex Total between the fiberglass and the metal sheeting.
4. Noise Reduction
Fiberglass insulation also helps dampen external noise, making metal buildings and pole barns quieter. This is especially beneficial for buildings near busy roads, farms, or industrial sites.
5. Cost-Effectiveness
Compared to other insulation options, fiberglass is one of the most affordable solutions available. It provides excellent performance at a fraction of the cost of more expensive alternatives, making it ideal for budget-conscious building projects.
6. Sustainability
Many fiberglass insulation products are made from recycled materials, making them an environmentally friendly option. By choosing fiberglass, you’re not only enhancing your building but also reducing your environmental footprint.
Why Insulate Your Metal Building or Pole Barn?
Without proper insulation, metal buildings and pole barns can experience significant heat loss, condensation issues, and higher energy costs. Fiberglass insulation solves these problems effectively, ensuring that your building remains comfortable, efficient, and protected from environmental challenges.
Boost Your Building's Performance with Fiberglass Insulation
Fiberglass insulation is the perfect choice for metal buildings and pole barns, offering a range of benefits, including energy efficiency, condensation control, noise reduction, and affordability. Whether you’re constructing a new structure or upgrading an existing one, installing fiberglass insulation is an investment that pays off in reduced energy costs, improved durability, and enhanced comfort. Turbo boost performance, by installing Prodex Total Insulation (insulation, radiant barrier, vapor barrier and air barrier in one product) between the fiberglass insulation and the metal sheeting.
Technical Information
Banded Liner System Data Sheet
Liner Banded System (R25, R30, R36 and R38 products): Provides leading-edge OSHA-compliant Fall Protection System and meets energy code requirements. A low permeance fabric serves as the vapor retarder preventing condensation, contributing to air barrier integrity, and providing a brighter resilient finish. Reduces noise transfer inside and outside the building, providing superior sound abatement.
