Creating SIP foam panels

Alaska Insulated Panels (AIP) is dedicated to providing energy-efficient cost-effective solutions to the many challenges associated with constructing buildings in cold climate environments. Alaska Insulated Panels is a manufacturer of polyurethane (PUR) structural insulated panels (SIP’s), utilizing state-of-the-art equipment. Polyurethane is a superior foam to expanded polystyrene (EPS or Styrofoam) which is used by most other SIP manufacturers.


Our commitment to providing a sustainable environment comes from our founding philosophy: "We must do the best we can to serve ourselves, but we must not forget that in the final analysis, we serve society whose approval of our actions forms the basis for the existence of our company."


AIP was founded to enhance and control the quality of SIPs used in the manufacturing of R-Valued Homes. The rising costs of shipping and poor quality control by other suppliers created the need for an Alaskan manufacturing plant to supply R-Valued Homes with quality SIPs.

AIP SIPs are manufactured under closely monitored conditions and can be fabricated to fit nearly any building design. The result is a building product that is extremely strong, energy-efficient, cost-effective, and eco-friendly.  Our SIPs will save you time, money, and labor.

The Process:

Fabrication is a process that starts with a set of building plans (blueprints) that have been developed by architects, building designers, or owners. From these plans, shop drawings are created and engineered to specific geographical design parameters. Shop drawings detail all of the fabrication pertaining to the building envelope i.e. wall length and height, window and door rough openings, gables, floor, roof, and added details specified by the engineer.


SIP panels are then fabricated to the specific dimensions shown on the shop drawings and routed to be able to add dimensional framing lumber for top and bottom plates, corners, window and door openings, headers, electrical chases, etc. as specified. Panels are then marked and numbered as shown on the shop drawing; these numbers also reference the location and sequence of installation on the job site. Wall assemblies are then dry-fitted and checked for accuracy. Panels are packaged by location, (i.e. foundation, floor, roof, east wall, etc.) wrapped, and banded for shipment.

Design Friendly

AIP SIPs can be used in almost any structure design.

Highest Fire Rating

The Polyurethane foam used by AIP is UL rated class “1”, has a flame spread number of 25, a smoke-developed number of 300, and is resistant to attacks by fuel, oils, most solvents, and other chemicals. Polyurethane is a cross-linked thermoset plastic that is highly resistant to heat, capable of withstanding temperatures of 800 ºF (427 ºC). When exposed to high temperatures, the polyurethane foam only chars, it does not melt. In residential applications, building codes require that the interior surface of any foam products to be covered with a 15-minute thermal barrier.

Structural Integrity

SIP’s are 4 times stronger than standard “2x” framed construction. When polyurethane foam is injected between two skins of standard building materials, a natural bond develops, thereby making the panel structurally analogous to an I-beam.

Energy Efficiency

Polyurethane foam has the highest R-value per inch of all the foam family, making it one of the most efficient insulating materials currently available. AIP’s polyurethane SIP’s have the highest R-values (R-8.0 @20⁰ F) per inch of all the insulating materials available in the market place today. Nominal panel sizes are 4 feet wide and 8,9,10 or 12 feet long with thicknesses of 4-1/2 inches (R-28), and 6-1/2 inches (R-44).


AIP pre-manufactured SIP building envelopes can be assembled by workers without extensive training 3 to 4 times faster than conventional stick framing, thus saving time and money without compromising quality.


The cost of the total completed project is comparable to all other current building types.  AIP panels are pre-cut and dry-fit (to check for accuracy) at the factory. This process reduces on-site labor costs, eliminates on-site waste, reduces the shipping of excess materials, interest on borrowed capital, and the environmental impact on local landfills - just to name a few.

Healthy Home

AIP SIPs help to prevent mold and mildew and block airborne pollutants. When a properly designed heating/cooling and ventilation system is added to an AIP SIP building system, you get the most energy-efficient and healthiest building available in the market today.

By combining its structural integrity, high R-value, and perm rating, a polyurethane foam core SIP creates an alternative building product that delivers the most energy-efficient solution to homeowners, builders, and commercial businesses available today.

How you can save money building with AIP SIPs:

  • Building your project using AIP SIPs allows you or your builder to complete six framing processes at one time

  • Pre-fabricated and cut in our manufacturing plant where it's dry fit and checked for accuracy before being shipped to you

  • Locally made in Alaska, not on a barge to Alaska

  • Electrical chases and boxes are pre-cut, saving your electrician time and materials and making the installation of wires a breeze

  • Installation of the building envelope can be completed 75% faster than conventional stick framing, resulting in saved man-hours

  • Reduced landfill cost because AIP SIPs have been precut at the factory

  • Reduced mechanical equipment costs because of the superior R-value of AIP SIPs

  • Healthier home - better indoor air quality when used with a proper mechanical ventilation system

  • 20 year limited warranty
