What Are Structural Insulated Panels (SIPs)

Structural insulation panels, commonly known as SIPs, continue to gain traction. While they date back to the 1950s, they’re now used as a faster and more effective building system than traditional options. The sudden upturn in popularity has left many homeowners wondering if they’re the next big thing in the construction niche or just a fad. In this blog post, we’ll explore in detail what SIP construction is, different SIP types, and the pros and cons to help you decide whether they’re the right choice for your next construction project.

Structural insulated panels are prefabricated OSB panels made from various insulation materials mainly used to build walls, ceilings, and floors for residential and light commercial buildings. Other materials used to make SIPs besides the OSB panels are plywood, steel, aluminum, cement board, stainless steel, fiber-reinforced plastic, agricultural fiber, or fiber-cement. They’re prefabricated, meaning that they are fitted on the construction site. They’re installed in a standard system that helps builders to quickly and easily install them during construction.

When taking your DIY home renovation project to the next level, Structural Insulated Panels (SIPs) are the secret weapon you never knew you needed. These aren’t just ordinary panels; SIPs are known for their ability to fit nearly any building design and provide far superior performance compared to traditional construction. Let’s dive into the details to better understand what makes SIPs unique.

Components (How they are Made)

SIP panels are assembled under controlled conditions to ensure quality and performance. An insulating foam core is sandwiched between two structural facings at the core of a SIP. This sandwich panel construction often includes sheet metal and creates a firm and efficient building envelope that is structurally sound.

  • Insulating Foam Core Sandwiched Between Two Structural Facings: The panel’s core is where the magic happens. With high r-values, the foam core sandwiched between two layers provides remarkable insulation.

  • High R-Values: With R-values surpassing many other building panels, SIPs offer remarkable insulation, contributing to greener living.
  • Comparative Efficiency: Compared to alternatives like insulated concrete forms, SIPs work in synergy with other elements of your home to create a more energy-efficient space.

Structural Insulated Panels are no longer just for professionals. Whether it’s sheathing a wall or creating an entire roof system, the versatility, structural integrity, and energy efficiency of SIPs offer DIY enthusiasts a way to take their projects to new heights. Their ability to adapt and provide solutions for everyday problems in traditional construction methods makes SIPs an invaluable tool in the modern DIY renovation toolkit. From the foam core sandwiched between two facings to the proper ventilation they ensure, SIPs are revolutionizing how people think about home renovation. And they’re just waiting for you to give them a try.

Types of Structural Insulated Panels

The most common types of SIPs use insulation foam cores made from expanded polystyrene (EPS), rigid polyurethane foam(PUR), and extruded polystyrene (XPS).

Expanded Polystyrene SIPs (EPS)

Expanded polystyrene is a type of wall construction method made up of a lightweight white, rigid, thermoplastic foam membrane made using polystyrene beads. Depending on its intended application, it’s made in varying densities for different physical properties. It’s majorly used in the packaging and construction industries for:

  • Shipment protection
  • Floatation
  • Insulation
  • Geoform
  • Insulated panel systems
  • Wall cladding systems
  • Waffle pods
  • Home roofing insulation

EPS for packaging is shock absorbent, making it ideal for storing and transporting fragile and expensive items such as pharmaceuticals and electronics. Its exceptional thermal insulation, moisture resistance, and compression resistance properties ensure that perishable goods stay fresh and correctly stacked throughout transportation.

EPS used in the building and construction industry is inert, does not rot, and has no nutritional value. This means that it does not attract pests. It’s also strong, durable, and lightweight, making it a versatile building material. Besides making insulated panels for walls, roofs, and floors, it’s also used to fill voids in civil engineering projects, railway and road construction, and as a floatation material while constructing pontoons and marinas.

Rigid Polyurethane Foam (PUR)

Polyurethane foam is a filling material used in engineering. Its physical and mechanical properties, including high thermal insulation, low density, and high shock absorption, make it ideal for thermal insulation, potting, and load-bearing. These foams are used in window and door assembly. It’s used to insulate electricity installation, hot and cold water pipes, roofing tiles adhesion, tightening terraces, insulating industrial roofing, and concrete shear wall buildings.

Extruded Polystyrene (XPS)

Extruded Polystyrene is a high-performance, rigid thermoplastic polymer with a closed-cell structure. It’s a strong, lightweight, and flexible insulator that’s absorption resistant, making it ideal for various building applications. It’s used for wall and ceiling insulation under concrete slabs such as car parks, decks, balconies, insulating inverted roofs, and commercial suspended ceilings.

Advantages of SIPs

There are endless reasons to build your residential or commercial properties with SIPs. Below is an overview of a few of these reasons:

Saves Heating or Cooling Bills

If your current energy bills are high, your home is likely losing heat through air leakage or wall conduction. Using Structural Insulated Panels ensures a high insulation efficiency to prevent heat loss. As these panels reduce heat loss, you can save up to 60% or more on heating and cooling costs.

Eco-Friendly Homes

The need for carbon-neutral energy efficient homes is surging. SIPs are among the most environmentally friendly construction methods in today’s market.  The foam core of SIP panels is made from oriented strand board (OSB3) extracted from young farm-grown trees that produce oxygen and remove a lot of carbon dioxide from the atmosphere. Compared to mature trees, these young trees are renewable, recyclable, and biodegradable.

Building Design Flexibility

If you’re still getting familiar with the latest building technologies, you might confuse SIPs with old prefabricated buildings. With the help of Excel Builders, you can use SIPs to build different designs, from complex to simple yet beautiful designs.

You can uniquely design and custom-build your project. The only potential limitation is your imagination. You can clad the project with anything you prefer once the project is done. Whether a traditional build with a classical stone finish or a modern white abode with large swathes of glass, the sky’s the limit with SIPs.

Long Lasting Buildings

Following SIPs general precautions during construction ensures that the SIP structure lasts longer. Some safeguards include thorough drying of panels should they get wet before construction and loosely covering to enhance air movement and drying.

The long-term performance of a construction project largely depends on its repair and maintenance. SIPs are durable and can withstand extreme weather conditions. As long as they remain weather-tight and you maintain them accordingly, you can expect them to last for at least 60 years.

Tips for a Successful SIPs Project

Whether you or your builder are using structural insulated panels for the first time, here’s what you should consider for a successful project:

Do a Thorough Panel Research

If you’ve decided to build your new home with SIPs, It’s good to note that there are different SIPs. With different types available on the market, ensure you know the panels’ composition and advantages. Along with your budget, consider critical factors such as thermal qualities, jointing system for airtight envelope, certifications and fire performance, strength, and stability.

Plan Ahead

Plan to know where the electrical chases, backer panels, and rough openings are needed before the project’s onset. Think about the labor and equipment when handling the SIP panels. If your project requires large panels, consider using a crane or a forklift to install them. Arrange for this equipment beforehand for a seamless installation.
