Other Factors That Affect Cost
SIPs are known for having improved strength and insulation, which saves money in the long run. However, when it comes to cost, several factors can affect the overall price of a SIP panel project, including the thickness and R-Value of the panel.
Cost by R-Value of SIPs
The R-Value of each SIP panel determines how much insulation it provides and is correlated to the panel’s thickness and the material used. The most popular insulation used for SIPs is expanded polystyrene rigid foam (EPS), which has an R-Value of about 3.6 per inch of thickness.
On the other hand, polyurethane has a much higher R-Value of 6.8 per inch and is an ideal option if your budget allows it. SIPs range in thickness from 4.6 inches to 12.25 inches, with total R-Values ranging from 16 to 48.
Generally, a 4′ x 8′ panel with an R-value of 16 may cost up to $240, while a 48 R-Value panel may cost up to $290 on average. Prices increase by about 5% for every 8 points of R-Value and each inch of thickness. So, the higher the R-Value or the thicker the panel is, the more you can expect to pay.
With this in mind, here is a breakdown of the average cost of 4′ x 8′ panels with different insulation levels:
| Panel Thickness(Inches) | R-Value | Average Cost Per Square Foot | Average Cost Per 4′ x 8′ Panel |
| 4.6” | 16 | $7.50 per sq. ft. | $240/panel |
| 6.5” | 24 | $7.87 per sq. ft. | $252/panel |
| 8.2” | 32 | $8.26 per sq. ft. | $263/panel |
| 10.2” | 40 | $8.67 per sq. ft. | $276/panel |
| 12.25” | 48 | $9.10 per sq. ft. | $290/panel |
Generally speaking, when selecting SIP panels for a project, investing in higher-quality material that offers greater insulation is worthwhile. That way, it will help reduce heating and cooling costs down the road.
SIP Cost By House Size
The size of your home is directly related to the cost of your SIP installation. More panels will be needed for a larger, multi-story home, increasing the price.
The cost of R-16 insulation SIPs will typically range between $7 and $12 per square foot, depending on the panel size. A homeowner with a 2,000 sq. ft. home without a truss timber frame can expect to invest somewhere between $14,000 and $24,000 on the panels alone.
In a similar manner, R-30 SIPs for the roof may cost around $8.26 per square foot or $826 per roof square (100 square feet). You will likely require about 20 roofing squares for a 2,000 sq. ft. house, bringing your roof costs alone to approximately $16,500, without professional installation.
Here is a breakdown of SIP costs for several home sizes:
| Home Size(Square Footage) | Average Cost for Wall Panels | Average Cost for Roof Panels | Total Cost (Materials Only) |
| 1,800 sq. ft. | $12,600 – $21,600 | $14,870 | $27,470 – $36,470 |
| 2,000 sq. ft. | $14,000 – $24,000 | $16,500 | $30,500 – $40,500 |
| 2,200 sq. ft. | $15,400 – $26,000 | $18,170 | $22,570 – $44,170 |
*Note: According to EnergyStar.gov, for optimal performance, a SIP project should use insulation panels with an R-value of at least R-16 for the walls and R-30 for the roof. For a higher-performance SIP house, an R-value of R-21 for walls and R-50 for the attic is recommended.
It’s important to bear in mind that these are only rough estimates of the cost of SIPs for different home sizes. Factors such as the size and configuration of your house, as well as local climate conditions, could cause the actual cost to vary significantly.
To get an accurate estimate, it’s best to consult a professional contractor or home builder, someone with experience in SIP construction, who will factor in all these considerations.
SIP Material Type
On average, the prices of SIPs range from $7 to $12 per square foot, depending on several factors, including the material and insulation type used. SIP panels are usually made from OSB (Oriented Strand Board) and rigid insulation material. They are typically used to create high-performance walls, roofs, or floors.
SIPs OSB
The OSB used for SIP panels, also called insulated panel skin, is one of the most popular components in the industry due to its durability and energy efficiency. The oriented strand boards are made of wood strands that have been chemically glued and compressed together to create a strong, lightweight material.
SIPs Rigid Insulation Material
Regarding rigid insulation material, polystyrene foam is the most widely used. This foam is often referred to as EPS (Expanded Polystyrene).
EPS is an excellent choice for insulation, providing a solid barrier with a high R-Value. However, if you’re looking for even better insulation, polyurethane foam (PUR) is the way to go. Polyurethane foam is more expensive than EPS but offers a higher R-Value.
Other insulation materials that can be used with SIP panels are:
- Polyisocyanurate
- Magnesium oxide
- Graphite
Labor Costs
SIPs are becoming increasingly popular for home construction and renovations, given their fast installation time, which reduces labor costs. Framing a home with SIPs takes around a week, whereas traditional stick framing can take much longer.
Since the SIP panels are assembled in a factory, much less labor is needed on-site during installation. Installing them can substantially reduce total construction time, resulting in savings on labor costs. Compared to other building methods, a homeowner can save up to 55% when using SIPs.
A carpenter and crew would typically charge an hourly fee to install SIPs, but factors such as the regional cost of labor, complexity of the structure, supplies, and tools needed can influence that rate. Generally, foundations, roofing, and windows will be the most expensive components to install. On average, a carpenter will charge anywhere from $50 to 100 per hour.
