1. What are Premier SIPs?
Premier Structural Insulated Panels (or SIPs) are a high-performance engineered wood product with a super-insulating core of rigid expanded polystyrene (EPS), structurally laminated and pressure cured between two sheets of oriented strand board (OSB). The result is a highly efficient structural building system that is extremely strong, predictable, energy efficient and cost effective.
Premier SIPs can be used for a building’s roof, walls and/or floors.
2. Why should I choose Premier SIPs over stick built methods?
Quality – Have you ever looked down a stud wall and noticed how it bends, bulges, twists and cups due to the increasingly poor quality of lumber? Have you ever tried to hang a large picture or mirror and had trouble finding the stud?
This does not happen with a Premier wall. Our walls are straight, plumb and square. The continuous wood surface also offers a sound nail-base for all exterior and interior finishes. SIPs are also structurally far stonger than Stick and Batt walls, far exceeding all NZ earthquake regulations.
Comfort – Without hesitation, your Premier SIPs home will be one of the most comfortable, quiet and clean structures you will ever own. Unlike a stick-frame home, in which thermal performance is an afterthought, insulation is an integral part of a Premier SIPs Home. Air and moisture infiltration is greatly reduced because the exterior envelope is tighter.
Peace of Mind – People who consider building their dream home do so because they want it to be uniquely theirs and to be perfect for a lifetime. Too often, frightened by the horror stories that their friends have told them, they choose to buy a “spec” house instead.
In a Premier home the framer “installs” the panel sections rather than “builds” them. This saves time and ensures that the walls are straight and plum.
Premier SIPs can positively impact many stages of the building process and help you stay on schedule. A few examples:
- The insulation is already incorporated into our panels.
- The electrical chases are factory installed in the foam, eliminating the time and labor expense associated with onsite drilling.
- The walls are flat and plum so the drywall, door and window installers complete their work faster along with a better final finish.
- The interior finishes, including cabinetry, flooring, moldings, counter tops, etc. will be installed easier due to the continuous attachment surface provided by the OSB. No more searching for studs or shimming bowed walls.
- The engineered advantage of building with Premier SIPs is that they are made with “factory precision.” Perfect panels mean perfect walls allowing a building to be very tight. This reduces the size of your heating and air conditioning unit (HVAC) by up to 40%, giving you immediate savings. And, homeowners will enjoy up to 60% lower energy bills annually.
3. What is the cost?
Building with SIPs generally costs about the same as building with wood frame construction, when you factor in the labor savings resulting from shorter construction time and less job-site waste.
Other savings include reduced heating and cooling bills for the lifetime of your SIPs home.
The cost to build a SIPs house depends entirely on its design. Generally the installed cost of Premier SIPs is comparable to stick framed construction. But when you look at the benefits of labor savings, and less waste, SIPs offer short-term construction savings as well as long-term benefits for the homeowner in energy savings.
The following is an independent study demonstrating these energy savings: Mark Whitaker, an independent energy consultant in Mesquite, Texas, compares SIPs vs. stick frame building envelopes and projects the utility cost one can expect to pay based on the type of HVAC system, local utility rates and heating and cooling days. Here is an analysis comparing the operating costs of a 1,522-square-foot (approx 144m) Dallas home using two different construction envelopes.
|SIP Energy Efficient Home||Conventionally Constructed Home||Home Owners Pocketed Savings|
|Estimated Operating Costs @ 4% Annual Cost Increase||5 years
4. What style of houses can be built with SIPs?
Virtually all styles of houses can be built using Premier’s structural insulated panels. Premier structures are being built in all kinds of environments. North Island, South Island, by the beach or in the mountains. Any environment, hot, cold or wet is ideal for Premier SIPs.
5. What is the insulation advantage to building with SIPs?
R-Value is a measure of a material’s resistance to heat flow. The higher the number the better the material is at insulating. According to the Dept. of?Energy, thermal breaks such as corners, windows, doors, and stud walls dramatically reduce the stated R-Value of virtually every product on the market except SIPs. As an example, a 2×6-stud wall with R-3.3 fiberglass batts has an R-Value of 2.4. A six-inch Premier wall has an R-Value of 3.8. Simply put, a 6″ Premier wall out performs a 6″ stud wall by 58%.
6. How strong are Premier SIPs?
Premier SIPs are extremely strong. Studies have shown that Premier SIPs are at minimum 20% stronger than dimensional lumber.
Strength in building materials and systems is judged by the materials’ ability to withstand the forces of nature. Data to determine strength properties is gathered by destructive testing, and specific tests are utilized to evaluate a SIPs’ performance in high winds, earthquakes and snow load conditions The testing program on Premier’s panel systems is the most extensive in the industry. Our SIPs are exceptionally strong in racking diaphragm shear capacities, which are the primary structural properties that engineers are concerned with when designing for seismic and hurricane events. Not only do test results show Premier SIPs are stronger, but natural disasters have proven it time and again.
7. How are SIPs more environmentally friendly than other building methods?
Premier SIPs are better for the world around us. Premier’s SIPs panels are so energy efficient, that homeowners regularly save up to 60% on utility bills. Premier SIPs help reduce the demand for fossil fuel consumption (such as gas, oil and coal) and also reduce the release of greenhouse gas emissions (like carbon dioxide) into the atmosphere during the years you heat and cool your home, resulting in a cleaner environment.
Premier SIPs also promote green building benefits, as they are 100% recyclable and they significantly reduce jobsite waste (by up to 60% reduction) in comparison to conventional stick-framing construction methods.
Premier SIPs are better for your personal environment. Studies linking respiratory disease, allergies and other diseases to indoor air quality have spawned an array of non/less toxic products and improved indoor ventilation. Our panels are very airtight giving you precise control over the indoor air quality of your home, which helps to keep out allergens, humidity, dust, etc.
Premier selectively chooses materials that are best for the environment. The Expanded polystyrene (EPS) core used in Premier’s structural insulated panels is manufactured using a low-environmental impact process of steam expansion that uses pentane and contains no CFCs (Chlorofluorocarbons) or HCFCs (Hydrochlorofluorocarbons) or formaldehyde. EPS is an inert material, so there are no issues with dust or off-gassing.
The oriented strand board (OSB) sheathing used in Premier SIPs is made from harvesting fast growing new-growth trees, making the resources renewable and sustainable, no old-growth timber is used.

8. Are Premier SIPs insect-resistant?
Ants, termites and other insects are common throughout the United States and can affect both stick frame and SIPs buildings. Our expanded polystyrene beads are coated with an insect-resistant product before the molding process. Premier SIPs are also sprayed with a natural, non-toxic insect-resistant mineral through our quality control procedures to help combat these types of insects. SIPs are no more susceptible to infestation than stick frame. Good construction practices should be used in the design and construction of SIP buildings to avoid insect infestation.
9. How do Plumbing and Electrical integrate with SIPs?
While there are some specific techniques that your subcontractors will need to become familiar with, building with SIPs will not create a significant roadblock in your construction.
Plumbing is very much the same as Sick frame techniques.
Electrical chases are manufactured into our panels at 16″ and 45″ above the floor and every 4 feet on center vertically in the walls. Special chases can also be installed into our panels to accommodate low voltage wiring. Wiring is simply pulled through the chases after the panels have been installed.
10. Why is a Premier SIPs project completed faster?
The panelized portion of a structure goes up much faster than standard stick frame construction, and our panels will be stronger, straighter and greener than stick frame methods.
SIPs arrive on the jobsite precut per your floor plans. Your dedicated Premier project manager will help coordinate drafting and engineer your shop drawings. Your SIPs are manufactured in large panels according to your plans. When premier manufactures your custom panels to size, we cut out windows, oors and gable ends. Reducing the need for time intensive (and costly) window and door framing.
To further ensure speedy installation, all PBS SIPs arrive to the jobsite pre-numbered to coordinate with shop drawings.
The simple fact that SIPs are pre-insulated also saves the insulation step in the construction process.
11. Why are more people building with SIPs now than ever before?
Stronger houses. Straighter, more predictable roofs, walls and floors. Greener structures.
Consumers are demanding better quality building products, healthier indoor environments and they also have a higher level of environmental responsibility than in previous decades. Builders and architects are designing to meet these needs. And SIPs fit the need perfectly.
Builders are finding once they start with SIPs they have a hard time going back to stick frame construction. Premier SIPs save builders time and money with faster installation, while creating a stronger, more efficient home.
Across the country, Premier SIPs are a part of luxury homes, industrial warehouses, tract developments, multifamily units, churches, wineries, health care facilities and retail shops. If someone can dream it up, SIPs can help build it.
