FOR SALE:  POLYISOCYANURATE FOAM INSULATION SHEETS

IMPORTANT NOTICE:

On Friday, January 31, 2014 I received my last truckload of insulation from the manufacturer.  Their upgraded facility now produces material at such high precision that “Factory Seconds” are no longer produced.

After 20+ years of buying, using, and (since 2009) selling this excellent product I must shift gears and wind down this little operation.  Everything will now be focused on selling the inventory I have and closing warehouses as they are emptied.

Based on previous years' sales, the current stock should last for 2-3 years although popular sizes/thicknesses will obviously deplete sooner.

There still is a considerable quantity of material to be sorted and inventoried and I will strive to get it all listed on this website soon.  And although there isn’t a price increase planned, I may have to should paying rent on the warehouses outpace income.

Thank you for your business, past and future.

Sincerely,

Dan V.


ADDITIONAL NOTES:

* This material is in SOUTH-EAST IDAHO and shipping more than a few hundred miles gets quite expensive!  More than 1000 miles is totally uneconomical.

FOR SALE:  POLYISOCYANURATE FOAM INSULATION SHEETS

Energy prices have nowhere to go but UP.    And on a fixed income how am I supposed to keep my home and shop warm?    After considerable research I determined the best way to hedge against rising energy costs is to INSULATE THE HECK OUT OF MY HOUSE/SHOP before even the price of insulation goes sky-high (all foam insulation products are made from oil and other hydrocarbon sources).   What better way to stay comfortable using a small fraction of the energy otherwise required?   It's called SUPER-INSULATING and every homeowner should learn about it and act before $300.00+/barrel oil gets here. Just one cockup by Iran or North Korea or ________ and it will be too late. (fill in the blank with who you think it will be)

Additional research then led me to this type material since it has the highest and most stable R-Value-per-inch-of-thickness (R-6/inch) of any insulation material commonly available to commercial and residential builders.  See HERE and HERE for good discussions of insulation materials.  A standard 2x4" wall using the common pink or white fiberglass batting has an R-13 value.  With the Poly-Iso insulation, that same 2x4" wall becomes R-23, which is even higher than a 2x6" wall using fiberglass batting( R-19).   With Poly-Iso insulation, that 2x6" wall jumps to R-35.   And being in a lightweight, rigid sheet form which is easily cut to fit between framed walls and rafters and glued to concrete walls, I knew I could install it myself, saving additional money.

One bad thing:  The cost of new Poly-Iso is quite expensive.   So to get the best price I bought the entire inventory (that's the only way I could get a good price break) of “over-runs” and “seconds” Polyisocyanurate insulation material from a large insulation manufacturer to use in my house, shop, potato cellars, and other out-buildings here in South-East Idaho.  I had much more than I needed to finish my projects and sold off the surplus.  Up until February 2014 I had occasionally been able to buy additional material.  To keep the Idaho State Tax Commission happy I had to incorporate as Zinsulation, L.L.C. and collect Idaho sales tax on non-exempt sales.  "Uncle Iris" is now happy, too.

 

This material comes in 4 foot by 8 foot (4’X8’) or 4 foot by 4 foot (4'X4') rigid insulation sheets in many different thicknesses/R-Values.  Typical R-Value is about R-6 per inch of thickness.  It has 15-25% better insulation R-value per inch thickness than expanded/extruded polystyrene or other similar materials found at the big-box home improvement stores.  (See the Product/Pricing Info page for more details).


If you don’t find the exact thickness material you want, the same R-Value is achieved by using multiple layers of thinner sheets.  And the cost is exactly the same since the material is priced by the cubic foot- not square footage.  So, for example, you want to fill the 3.5” void between 2X4 wall studs, you can stack two 1.5” sheets along with a ½” sheet to completely fill that 3.5” cavity while having a R-23 insulation value- the same as a single 3.5” sheet would provide.

This material is useful for insulating: homes, basements, shops, overhead doors, trailers, metal buildings, wood frame or concrete buildings, concrete floors/walls, greenhouses, animal shelter/barns, water pump/tank/well enclosures, and many other spaces where the highest R-Value-per-inch-thickness is desired (See the Picture Gallery page for more details and installation ideas)

 

As with most insulation materials, this material IS NOT FIREPROOF and thus must be transported, stored, handled, and installed using proper safety measures.  See Warranty Disclaimer page for more information on safety and building code requirements.

Material may be purchased by the sheet,  by the bunk, or by the truckload.   A "bunk" is a cubic volume bundle of material that measures 4'x4'x8' in size.  The number of sheets in a bunk is determined by the sheet thickness.  Since a bunk should be 48" (4') in height, only enough sheets are stacked up to get as close to that height - rounding as needed.  Thus a bunk of 1" sheets would be stacked 48 sheets high.  Please see Product/Pricing Info page for price breaks/quantity discounts.  But no matter how much you purchase, the price-per-sheet will be less than half of what the home improvement stores charge for similar products.

 

Material purchased in “bunk” units allows better pricing.  The square-footage per bunk will vary depending on the thickness/number of sheets in the bunk.  Individual bunks contain one material size and thickness only.  Refer to the table in the Product/Pricing Info page for number of sheets and square footage per bunk data.

 

These insulation sheets consist of a closed-cell polyisocyanurate foam core with dark-brown, glass-reinforced mat facers laminated to both sides.  This facer material is much like a heavy-duty version of the construction-paper your teacher gave you in Elementary School to cut into shapes for art projects.  This makes for a rigid, lightweight sheet that typically exhibits standard compressive strength of 20 psi and an insulating value of R-6 per inch of thickness.  See MISCELLANEOUS page for more info.

 

 “OVER-RUN” sheets usually appear factory-perfect in every respect.  They may be of standard thicknesses/dimensions, or custom-run material of unique dimensions.  OVERRUN bunks are packaged in heavy-duty white shrink-wrap bags.  Although of a higher standard than “seconds”, they nonetheless come without warranty of any kind, just like the “SECONDS” material.

 

“SECONDS” are sheets that were pulled from the production line by the Quality Assurance inspectors for visible irregularities such as cosmetic defects, interior/edge pockets and/or voids, irregular or rough edges, out-of-tolerance dimensions/density, etc.  Typically, only the ½ inch material might have pockets or voids that could materially affect the insulating value of the sheet (See PICTURE GALLERY page).  SECONDS bunks are not wrapped or packaged in bags as the OVERRUN material is.
