SIP panelCan be orderedFischerSIPS ↗
FischerSIPS has no published price and is engineered to 200 mph wind.
FischerSIPS does not publish a snow load or a price for this model, so 56 percent of the fields we score are blank.
None of that tells you whether it works on your land. Wind, snow, seismic and flood performance are site specific engineering, so the only useful answer comes from running this kit against your address.
Completeness
44 percent of the fields we score are backed by something FischerSIPS published. Why completeness is never part of the grade.
The thing nobody else will tell you
This kit cannot be scored on its own. Nothing on this page tells you whether it works on your land.
Wind, snow, seismic and flood performance come from your address, not from this kit. Put in an address and the gates run against the real requirement at that point.
Free, and it stays free.
Against our own kit
The owner of this site makes a kit home too. Rather than hide that at the bottom of a policy page, here it is at the top of every kit page, on published data only, with the same eight questions in the same order every time. Where a maker publishes nothing, this says so instead of guessing.

Both publish 2 of these 5 measurable figures. We publish no design wind speed and no snow load, which are the two figures that decide whether any kit can be permitted on a given lot, so on the numbers that matter most we cannot yet prove anything. A blank is a maker who has not published a figure, and it is not a fail. How this conflict is handled.
The Octolithic Kit Grade
Rubric v1.0, August 2026. Site fit is not in this grade, because it depends on your land rather than on the kit. Every weight, and what we refuse to grade.
What the maker publishes
Everything here came off FischerSIPS's own pages, cited at the bottom. A blank is a blank: we never fill one in.

What the maker says it resists
Design capability as published. Not a certification, not a rating of your house, and not proof against anything.
| Engineered wind speed | 200 mph |
|---|---|
| Roof snow capability | Not published |
| Seismic | Company cites the 2016 Kaikoura, NZ earthquake (SIP structures reportedly undamaged) and notes SIPs have been recognized in the IRC since 2007 (Section R610). This is marketing/case-study content, not a specific engineered seismic design value for a project. |
| Fire | Company states 1-hour fire-resistance rating for a typical SIP wall assembly with 1/2in Type X gypsum interior; cites Intertek testing to NFPA 286 and ASTM E119 with some assemblies rated up to 2 hours. |
Price
Not published
This maker publishes no price. That is the single most common gap in the Index, and it is the first thing to ask them.

What else we found
The 200 mph figure and fire/seismic notes come from FischerSIPS' own marketing/case-study page (hurricane-earthquake-fire-resistance), not a stamped engineering design table for a specific project - treat as a company claim, not a code-report design value. No pricing published; quote-only.
Questions to send this maker
Generated from what they left blank. Every one of these is a thing they could answer today and have chosen not to publish. Copy them into an email. If they answer, tell us and we will update this page with the citation.
- What does this cost, in dollars, and exactly which build stages does that number cover?
- What ground snow load can the roof carry, in pounds per square foot, and is that the ground load or the roof load?
- Which foundation types does this kit support, and can it sit on piers above a base flood elevation?
- What is the roof R value, and is it nominal or whole assembly?
- What is the finished square footage of this model?
- What is the lead time in weeks from deposit to delivery, right now?
Across the whole Index, the average kit publishes about a quarter of what a buyer needs. This maker is at 44 percent.
Questions people ask about the FischerSIPS
Answered from what FischerSIPS publishes, including the answers that are "they do not say".
How much does the FischerSIPS cost?
FischerSIPS publishes no price for this model. Across the whole Index only about a third of makers publish a price in dollars at all.
What wind speed is the FischerSIPS engineered to?
FischerSIPS publishes 200 mph for this model. That is their design capability at the conditions they assume, not a rating of your house. Your required design wind speed depends on your address, your Risk Category and your Exposure Category.
What snow load can the FischerSIPS roof take?
FischerSIPS does not publish a snow load for this model. Around one maker in twenty does.
Can you actually buy the FischerSIPS?
Yes. FischerSIPS takes orders for this model today.
What foundation does the FischerSIPS need?
FischerSIPS does not publish foundation options for this model. That matters more than it sounds: in a FEMA A or V flood zone the finished floor has to sit above the base flood elevation, and a kit offered on a slab only cannot get there.
How well does the FischerSIPS stand up to a hurricane or a wildfire?
The honest answer is what it resists, and under what conditions. No kit home is proof against either, and any page telling you otherwise is selling. "Hurricane rated" has no legal definition in the United States, no house can be tornado rated, and whole building certifications like LEED, Passive House and HERS all require a built, sited, inspected home and cannot be attached to a model from a spec sheet. What a maker can honestly tell you is what the design resists and under what conditions. For this model, that is a 200 mph design wind speed.
Will the FischerSIPS work on my land?
Nothing on any spec sheet can answer that, including this one. Wind, snow, seismic, flood and soil requirements come from your address, not from the kit. The Octolithic runs every kit in the Index against the published hazard data for your point and shows you what survives and why the rest did not. It is free.
Compare
Nothing here is ranked by what anyone pays us, because no kit maker has ever paid for placement on this site.
Other sip panel kits in the Index
How it compares
It documents more than the average sip panel kit, 44 percent against 30, and more than 20 of the other 24 we hold. Publishing a design wind speed puts it in the 4 percent of sip panel makers that do.
Computed across all 515 kit homes in the Index, 25 of them sip panel. Recomputed on every build.
