Fischer SIPS — Superior Insulation, FSC OSB also Available

Fischer SIPS being installed

Fischer SIPS contacted me regarding their company’s SIPS panels. I’ve written about SIPS before and their benefit for any building project.

Fischer SIPS have an added benefit of specifying SIPS with FSC certified wood.

If you’re not familiar with SIPS, they are “structurally insulated panels” used for building homes and commercial structures and are an “all-in-one” product providing the framework and insulation for a project at the same time. SIPS are a made as a “sandwich” of Oriented Strand Board (OSB), insulation, and OSB. SIPS are available in varying dimensions with varying projected R-values. The benefits of using SIPS in a building project are numerous.

  • Energy efficiency is significant. According to the Fischer website, SIPS’ actual R-value (ie., the number they’re given based on their thickness), and their performance R-value are significantly different, with the latter being higher than the performance R-value. This statistic is unusual because, generally speaking, R-values will be the same or lower than “performance R-value” due to other factors (construction methods, thermal bridging, etc.). Further, air tightness is superior to a stick-frame built home because the SIPS are fully insulated and there are fewer thermal bridges (where heat can transfer from warmer to cooler areas). Heating bills are significantly lower than a traditional stick-frame and fibreglass insulated home.
  • Less waste on site. Building a house is one of the highest waste producing activities around. Using SIPS that are constructed in a factory significantly cuts down on waste on the building site. Within the manufacturing facility, excess insulation (in this case expanded polystyrene — EPS) from SIPS production can be reused for other EPS uses.
  • Use of rapidly renewable resources. OSB is made from small, rapidly growing trees not suitable for other uses. A full 85-90% of the tree can be used to make OSBs.
  • Speed of Constructing a home. SIPS can be assembled in up to 30% less time than a stick-framed house (although a crane is necessary for the roofing panels) because the frame and insulation are all in one.
  • SIPS are ideal for cathedral ceilings because of the insulation already in the panels.
  • Fischer SIPS are available with FSC certified OSB (in 4’x8′ and 4×12′ dimensions only).

Fischer ships its products across the United States and Canada and as far away as Russia.

Thermapan SIPs From Fort Erie Ontario

October 18th, 2010

Thermapan Wall SIP

Structural Insulated Panels (SIPs) offer many advantages over traditional home building techniques which use 2×4 lumber framing and concrete foundations. For one, the panels can be assembled much faster than a house can be framed, for another, using SIPs for exterior wall panels will replace studs, insulation vapor and air barriers. SIPs are structurally very strong, and can bear three times as much weight across an even surface as traditional stick-framed walls.

But SIPs are probably best known for their insulation properties. Thermapan SIPs consist of a sandwich of two 7/16″ oriented strand board (OSB) with a “filling” of Expanded polystyrene (EPS) insulation. Because EPS is a closed cell insulation, it prevents air from entering the form which keeps its R value constant. Further, when SIPs are used to frame a house, they provide a superior air-tight seal that is difficult to match in traditional stick-framed homes.

Thermapan manufactures several different types of SIPs, each developed for a different application. Below are a few of the products they carry:

  • Exterior Wall SIP: (7/16 OSB, interior layer of expanded polystyrene). Dimensions: available in 4′ widths, and 8′, 9′ or 10′ lengths. Thicknesses: 4 1/2″ (R19), 6 1/2″ (R29) and 8 1/4″ (R38).
  • Roof and Ceiling SIP: Can be used for framing and insulating (including air and vapor barrier) cathedral ceilings, as well as for green roofs.  Available in 4′ widths, 8-16′ in length, 6.5-12.24″ thickness. R values range from R29-R58.
  • Floor SIP: Great for living spaces above garages and sunrooms. Width: 4′. Length: 8-16”; thickness: 6.5″-12.25″. R-value range: R29-R58.
  • PWF Foundation SIP: made for below grade uses. Consists of pressure-treated exterior sheathing that resists decay. These panels are constructed to support heavy loads. Exterior side of panel is 5/8″ PWF plywood, interior side is 7/16″ OSB. Length 8′, 9′ or 10′; thickness 8.25″ or 10.25″. R values: R38 or R48.
