Experience
Extreme Panels has been manufacturing SIPs since 1992. We are a family-owned business located in Cottonwood MN, in southwest Minnesota about fifteen miles north of Marshall.
Product
We manufacture wall and roof panels consisting of 7/16” OSB on both sides with expanded polystyrene in the middle. We also manufacture foundation panels consisting of 5/8” treated plywood with expanded polystyrene in the middle. Glu-lam splines are installed in every foundation panel 4’ on center for easy installation.
One-Stop Shopping
Once you have your plan, we can give you an estimate on as much or as little of the job as you want. We will estimate the foundation, floor, walls, ridge beams, roof panels or roof trusses, plus the miscellaneous materials – everything that’s needed to complete the structural shell. We pride ourselves in providing one of the most complete packages in the SIPs industry.
Service
We take pride in providing the highest quality panels together with the best customer service available. We will work with you from the day you bring us your plan until you glue and screw the last panel. If required, we’ll work with your building code officials providing them all the information necessary to grant you a building permit. We have NER code approval and are third-party monitored by UL Listings.
Once you have finalized your plan we will give you a free estimate breaking down each section (foundation, walls, and roof) so you know what each section will cost. We will also itemize the miscellaneous materials (screws, adhesive, expandable foam, splines, top and bottom plates) so you will know exactly what is needed for each section. Then, if you decide you would like to get your lumber locally, you can do that.
Most of the panels are laminated together with a fully-automated press that can laminate panels up to 8’ x 24’. The window and door openings, along with roof pitches,etc., are cut with a CNC German-made machine called a Hundegger. We can pre-cut all the window and door openings at the plant or you can do it at the jobsite. If needed, we will install the headers over the doors and windows also.

Terms
When the contract is signed, we require a down payment of 1/2 the total cost. The balance is due when the panels are delivered or picked up.
Freight
We have two of our own semis to deliver your panels. We also have a forklift that fits on the back of the semi so you don’t have to worry about having one on site to unload the panels. For farther distances we utilize outside freight carriers that tarp every load ensuring your panels arrive to the site dry and on time.
