Building owners and project managers are going for the green in 2023 when it comes to construction.

The “green” in this case is just as much about the cost of money in the current economic environment as it is about the environment.

“Growth in the industry has been slowed by high input costs, rising interest rates, inflationary pressures, and supply chain issues,” notes a global construction consultant firm in ForConstructionPros.com.

Both cost-effectiveness and sustainability are on the construction radar and insulated metal panels (IMPs) are a versatile “green solution” that can help achieve both goals.

With their unique properties, IMP roofs and walls provide significant benefits, including cost savings, energy efficiency, longevity, and reduced maintenance requirements – allowing building owners and projects to save money and construction costs while also contributing to a greener future.

Retrofitting with IMPs: An Economical Choice

Building owners seeking to upgrade their existing structures often face the challenge of balancing cost-effectiveness with desired improvements.

The question then becomes, when it is time to replace an aging roof, should you start from scratch and install an entirely new roof, or can you retrofit over your existing roof?

Retrofitting with IMPs offers several advantages, making it an economical choice compared to installing a completely new roof:

• Cost Savings: Retrofitting with IMPs can result in substantial cost savings compared to a full roof replacement. Traditional roof replacement involves labor-intensive and time-consuming processes, including the removal of the existing roof. This can be expensive, particularly if there are multiple layers of roofing materials to remove. With IMPs, the existing roof can remain in place, eliminating the need for costly tear-off procedures. The IMPs are directly installed over the existing roof, saving both time and money.
  
  
• Reduced Labor and Material Expenses: Retrofitting with IMPs significantly reduces labor and material costs. The installation process is relatively quick and straightforward, requiring fewer man-hours compared to a complete roof replacement. As IMPs come as prefabricated panels, there is no need for on-site cutting or extensive construction work. The panels are simply installed onto the existing roof using a specialized system, resulting in shorter project timelines and reduced labor costs.
  
  
• Minimal Disruption: Retrofitting with IMPs causes minimal disruption to building operations. The installation process is typically non-intrusive, allowing businesses to continue functioning with minimal downtime. This is particularly advantageous for commercial buildings or facilities where disruptions can lead to financial losses. By avoiding the need for extensive construction activities, building owners can save money while maintaining the smooth operation of their businesses.
  
  
• Enhanced Energy Efficiency: Retrofitting with IMPs brings energy efficiency benefits to existing structures. The insulation properties of IMPs provide superior thermal performance, reducing heat transfer through the building envelope. This results in improved energy efficiency and a more comfortable indoor environment. By reducing heating and cooling needs, building owners can experience significant cost savings on energy bills over the long term.
  
  
• Improved Building Performance: The superior insulation properties of IMPs help regulate internal temperatures, reducing temperature fluctuations and creating a more stable environment. This can enhance occupant comfort and productivity, particularly in areas where external weather conditions vary widely. IMPs also contribute to sound insulation, reducing noise transmission, and creating quieter indoor spaces.

IMPs Offer Energy Efficiency and Lowered Bills

IMPs are known for their exceptional insulation properties, making them a powerful tool for enhancing energy efficiency and reducing utility bills.

The insulation within IMPs acts as a barrier, minimizing heat transfer and maintaining a stable indoor temperature regardless of external weather conditions.

Key IMP energy efficiency benefits include:

• Reduced Heating and Cooling Needs: The superior insulation provided by IMPs significantly reduces the building's heating and cooling demands. The insulation core within the panels inhibits heat flow through the walls and roof, resulting in reduced heat loss during winter and decreased heat gain during summer. As a result, the building's reliance on HVAC systems for temperature control is reduced, leading to substantial energy savings and lower utility bills.
  
  
• Enhanced Thermal Performance: IMPs offer high R-values, indicating their thermal resistance and effectiveness in preventing heat transfer. This thermal performance prevents air leakage and thermal bridging, which are common sources of energy loss in buildings. By creating a highly insulated building envelope, IMPs minimize energy waste and maintain a more comfortable and consistent indoor environment throughout the year.
  
  
• HVAC System Optimization: The improved energy efficiency provided by IMPs can have a positive impact on HVAC system performance. With reduced heating and cooling loads, HVAC systems can operate more efficiently, requiring less energy to maintain desired indoor temperatures. This optimization not only saves energy but also extends the lifespan of HVAC equipment, reducing maintenance and replacement costs.
  
  
• Passive Design Integration: IMPs align with passive design principles, which focus on harnessing natural elements to maintain a comfortable indoor environment. By effectively insulating the building envelope, IMPs support passive heating and cooling strategies.
  
  
• Environmental Benefits: The energy savings achieved through IMPs contribute to a greener future by reducing the building's carbon footprint. Lower energy consumption means a reduced demand for fossil fuels and a corresponding decrease in greenhouse gas emissions.
  
  
• Compliance with Energy Codes and Certifications: IMPs' excellent insulation properties align with stringent energy codes and certifications, ensuring compliance with sustainability standards. Many IMP manufacturers offer panels that meet or exceed the requirements of programs such as LEED (Leadership in Energy and Environmental Design) and ENERGY STAR. By incorporating IMPs into building projects, owners can achieve energy efficiency goals and potentially qualify for incentives or certifications that demonstrate their commitment to sustainability.

IMPs Longevity and Lifespan vs. Other Materials

IMP’s durability and longevity, make them a wise investment for building owners.

With their robust construction and resistance to various environmental factors, IMPs offer an extended lifespan compared to many other building materials.

When it comes to longevity and lifespan, IMPs can boast:

• Durability: IMPs are constructed with high-quality materials, including durable metal exteriors and core insulation material. These components work together to create a strong and resilient panel system. The metal exteriors are often coated with protective finishes that enhance their resistance to corrosion, fading, and weathering. This durability ensures that IMPs can withstand the test of time and maintain their structural integrity in various climatic conditions.
  
  
• Resistance to Environmental Factors: IMPs excel in withstanding harsh environmental elements that can degrade other building materials. They offer exceptional resistance to moisture, preventing water infiltration and subsequent damage such as rot, mold, or structural decay. IMPs are also fire-resistant, providing an added layer of safety to the building. Additionally, they are resistant to pests, such as insects and rodents, which can cause damage to other building materials. The ability of IMPs to withstand these environmental challenges contributes to their longevity.
  
  
• Minimal Maintenance Requirements: IMPs require minimal maintenance over their lifespan, leading to cost savings and convenience for building owners. Unlike some other materials that may require regular painting, sealing, or repairs, IMPs generally maintain their appearance and functionality with minimal attention. The protective finishes on the metal exteriors help preserve their aesthetics and protect against corrosion. Periodic cleaning and inspections are typically sufficient to keep IMPs in optimal condition, reducing the need for costly and time-consuming maintenance tasks.
  
  
• Structural Stability: IMPs provide structural stability due to their rigid panel construction. The interlocking panels create a continuous and solid surface that enhances the building's strength and resistance to structural deformations.
