sIP Manufacturers
There are hundreds of manufacturers shipping SIP panels (sandwiched foam) worldwide, mainly in Europe and North America (where the numbers amount to several dozen). To reduce shipping costs and to ease the collaboration between your project architect and the SIP manufacturer, choose a manufacturer near to you.
Environmental considerations
SIP - or Structural Insulated Panels - are large engineered building panels for walls (and floors and roofs). SIP walls can be erected in just some few days, with minimal equipment.
Choosing a manufacturer that uses soy-based or other low-toxic adhesives, that is, a manufacturer that do not use formaldehyde in their products is an eco-friendly choice.
Also prefer a manufacturer that uses recycled content foam, polyisocyanurate, compressed straw panels, or EPS foam. EPS is the most common element of the core layer of SIP panels, and is more eco-friendly than polyurethane.
Alternative panels
Some manufacturers are offering alternative panels using fiber-cement siding, waterproofing materials, drywall in their interior skin, etc. Pay attention to these small-big details.
Pre-cut
SIP panels typically come to jobsite ready for assembly, without needing or allowing site adjustments. To achieve it, manufacturers use computer controlled equipment able to incorporate panel cutting instructions via CAD (computer aided design), following homeowner's guidelines.
Support
Most SIP manufacturers are able to provide technical design services and support for code construction acceptance. This last issue is important due to possible obstacles posed by building departments (lack of acquaintance with the SIP technology is common).
Warranties
Most Structural Insulated Panel manufacturers provide a typical structural warranty for the whole expected life of the building, subject to a proper installation and use. Warranties may include the insulation performance or insect-resistance.
finding manufacturers
To find manufacturers and certified installers, see organizations like SIPS (USA) and UKSIPS (UK).
