Insulation for steel buildings is essential to maintain the indoor temperature and prevent corrosion (due to mold formation). Different insulation materials are available exclusively for steel buildings that provide long-term structural integrity and increased lifespan.
This article discusses the purpose and types of insulation for steel buildings.
Purpose of Insulating a Steel Building
Insulation installed for a steel building performs certain functions and provides the following benefits:
1. Stabilizes the Building Temperature
Insulation in steel buildings slows down the movement of heat in winter (cold air in summer). It helps in providing a building envelope that controls the interior temperature of the building.
2. Reduced Energy Consumption
The insulation traps the thermal energy inside the building. It enables the occupants to regulate the temperature with less power, achieving energy efficiency.
3. Prevents Mold, Mildew, Rust, and Corrosion
Significant indoor and outdoor temperature variations can result in condensation issues that lead to mold and mildew. If molds and mildew are left unattended, they can cause serious health issues to occupants with allergies and respiratory problems.
Steel building insulation controls heat flow and prevents condensation. This insulation controls mold, mildew growth, and extreme issues of corrosion and rust.
Hence, it lets the building stay in prime condition for longer and protects the health of the occupants.
4. Noise Absorption
Metal building insulation keeps the sound or noise within the building by absorbing the reverberations. This property is amplified if extra interior padding is provided to the building.
In addition to the above functions performed by insulation in steel buildings, they are an important element in improving the return on investment for a metal building.
Types of Insulation for Steel Buildings
Four different types of materials are used to insulate steel buildings. Each material differs in its function and cost. Insulation for a steel building is selected by comparing the material with the shape, size, location, and purpose of the steel building.
1. Reflective Foil Insulation for Steel Buildings
Reflective or foil insulation is an insulation barrier made of aluminum or aluminized polyester. This insulation significantly brightens the exterior of the building. Foil insulation is easy to install but it is expensive.
2. Fiberglass Insulation for Steel Buildings
Fiberglass insulation is the most popular and cheapest method to insulate steel buildings. They are available in the form of blankets or rolls.
3. Insulated Metal Panels for Steel Buildings
Insulated Metal Panels (IMPs) are exterior wall or roof panels made of steel skin and an insulating foam core. This insulation is known for its superior thermal properties, design flexibility, quick installation, and aesthetics.
4. Rigid Boards for Steel Buildings
Rigid board insulation is a good choice for roof systems of metal buildings. They are easy to install and provide continuous insulation. Rigid board insulation is made from rugged, dense sheets of certain types of foam.
Every steel building does not require insulation. But metal building insulation is a good approach for saving money on heating or cooling and for adding to the building’s life.
Insulation for steel buildings is essential to maintain the indoor temperature and prevent corrosion due to mold formation.
Types of insulation for steel buildings are:
1. Reflective foil insulation
2. Fiber glass insulation
3. Insulated metal panels
4. Rigid boards
The advantages of insulating steel buildings are:
1. Stabilizes building temperature
2. Reduces energy consumption
3. Prevents mold, mildew, rust, and corrosion
4. Noise absorption
