The movement toward smaller homes is accelerating. The appeal of living a more simple life without the hassle and cost of a regular size home is attracting more and more people. As more people turn toward this sustainable lifestyle, they are looking to build their small house with materials that reflect that lifestyle. One of the best ways to do that is by building with SIPs or Structural Insulated Panels. SIPs are the building blocks of every prefabricated small house kit we sell.

What are SIPS?

Structural insulated panels (SIPs) are a high-performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facing boards.

SIPs are manufactured under factory controlled conditions and can be fabricated to fit nearly any building design.  The result is a building system that is extremely strong, energy-efficient, and cost-effective. Building with SIPs will save you time, money, and labor as well as delivering long-term value.

There are many reasons to choose SIPs for your small home build, but six, in particular, stand out.

6 Reasons to Choose SIPs for Home Building

1. SIPs are sustainable

One of the most significant selling points for choosing SIPs is it allows you to have a sustainable build. Sustainable building or “Green Building” uses less energy and reduces damaging carbon dioxide emissions. Structures built with SIPs often can be LEED certified. The Leadership in Energy and Environmental Design (LEED) is a set of rating systems for the design, construction, operation, and maintenance of green building which was developed by the U.S. Green Building Council. LEED-certified buildings achieve the most rigorous standards in sustainable building.

Sustainable building reduces the overall impact on human health and the natural environment. SIPs panels are one of the most sustainable choices for framing and roofing. A home built with SIPs is airtight and well insulated, making them a natural green product. This greater level of insulation means SIPs use less energy to heat and cool, reducing the reliance on greenhouse gases to maintain a comfortable temperature in your home.  Additionally, because SIPs panels are manufactured ahead of time to the exact specifications of your home design, they dramatically reduce construction waste.  

By choosing to build with sustainable SIPs, you can have a strong environmental impact. The best part? Energy efficiency means less heating and cooling costs, saving you money down the road. Building with SIPs panels is a win for the environment.

2. SIPs are quicker to build with

SIPs are faster and easier to build than traditional stick-built homes.  For one, you can get prefab small home kits that contain pre-measured and pre-cut SIPs. House kits come in a variety of floor plans but eliminate the need for a long design phase. Even if you build a custom home kit from SIPs, the panels offer significant time savings. Because the panels are self-contained framing and insulation, they eliminate steps in the home building process.

When you start building with SIPs panels, the entire wall and roof sections can be put up quickly. The panels are shipped to you to the exact measurements and specifications of your blueprint. SIPs are ready to install when they arrive, eliminating the time needed to perform the individual jobsite operations of framing, insulating, and sheathing traditional stick-framed walls. Piece your SIPs panels together, and voila!

3. SIPs are extremely energy efficient

SIPs are a great way to save energy. SIPs create a superior building envelope with high thermal resistance and minimal air infiltration. Many new home builders see energy savings of 50%-70% after moving into a house built with SIPs.  SIPs panels kits have a low impact on the environment and reduce energy costs. SIPs are fabricated in a controlled environment allowing for greater efficiency than site-built framing. SIPs also take less energy and raw materials to produce than other structural building systems. Yes, they are “green.”

4. SIPs improve air quality

Building with SIPs panels allows for better control over indoor air quality because the airtight building envelope limits incoming air to controlled ventilation. Controlled ventilation filters out contaminants and allergens, and also allows for incoming air to controlled ventilation. This will reduce the possibility of mold and dust. Many ventilation strategies can help with airtight homes. Many air filtration systems are constructed with materials that emit Volatile Organic Compounds (VOCs), but not SIPs. You can have a sustainable home that feels sustainable, too.

5. SIPs are strong

If you are building your own home, you want to ensure the product that you are using is durable. SIPs are one of the strongest building products available, with durability similar to a steel I-beam. The combination of the outer layer of SIPS, the oriented strand board and the inner layer of thick foam creates a long-lasting, strong product. SIPs are far more durable to inclement weather than traditionally framed homes. For the small home builder wanting to move to a more open environment, this is especially important. Additionally,  SIPs can have significant fire resistance if constructed properly.

6. SIPs offer better long-term value

SIPs are one of the fastest-growing new building methods. Although building with SIPs may initially have a slightly higher materials cost than building with wood frame, they provide far better, long-term value. SIPs are quicker to construct and reduce the time on construction on your home. Building with SIPs is far easier to install for the DIY home builder than traditional framed and insulated homes, significantly reducing labor and time costs.  Even if you do use a contractor or building crew to assemble your home kit with SIPs panels, the job can be done quicker and more efficiently than traditional building methods.

Of course, building with SIPs also has a positive impact by reducing energy costs.  The airtightness in the SIPs building envelope prevents air from gaining access to the interior of the home, reducing the costs to heat and cool your home. Additionally, if you build with SIPs you are likely to have less health impact from molds and dust.  The growth of the green, energy-efficient home market has led to an increased demand for a high-performance building.

Homebuyers are interested in sustainability according to a National Association of Realtors® survey that found to 62% of realtors had clients at least somewhat interested in sustainability. Also, 71% of survey respondents said energy efficiency promotion was very or somewhat valuable.

SIPs are definitely worth the investment. The improved indoor air quality decreased energy costs, and lower labor needs all add to the long-term value of choosing to build with SIPs. You can reduce construction labor costs. In the long run, this would be a significant investment.
