INVENTORY & PRICES                                             

                                   See bottom of page for DELIVERY SERVICES available.

November 1, 2015:  Please note that the tablet computer used to track inventory crashed.  The inventory numbers below are ESTIMATES ONLY.  The actual numbers could be somewhat lower.  Just call my cell phone number at the bottom of the HOME page to see if I still have the thickness(es) you want.  The effort to do a full and accurate inventory will be daunting and I just don't have the time right now.

  /R material uses a rigid and waterproof FIBER & RESIN facer material, not the standard dark paper facer. This material is new to me and was recently found when clearing out a smaller warehouse. There may be more found as I continue to close out the last of the smaller warehouses.

Note:  A "BUNK" is a volume measurement of 4'x8'x4' -  The same as a "CORD" used in firewood trade (128 cubic feet).

    *  Long Term Thermal Resistance (LTTR) values provide a 15-year time-weighted average in accordance with CAN/ULC-S770.
** Half-inch material is subject to voids and/or pockets that could degrade the sheet's insulating quality and thus is priced lower.

Please note that sheet thickness tolerance is + or -  1/6th  inch, and thus sheet measurement may vary from bunk-to-bunk and sheet-to-sheet.  If your application requires sheet thickness accuracy to be better than this, or would have a "not to exceed" or minimum thickness, let me know.  Under most circumstances I can screen sheets/bunks to your special tolerance needs for free on smaller orders.  For larger orders I may have to charge something for my time.

Remember:  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 the same since the material is priced by the cubic foot- not square footage.  So, for example, if 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-21 insulation value- the same as a single 3.5” sheet would provide.

All prices F.O.B. Grace, Idaho 83241

6% Idaho State Sales Tax charged on all non-exempt sales.  Exempt sales are those where the material is shipped by a licensed COMMERCIAL CARRIER or Zinsulation outside of the state of Idaho.



Since a fair percentage of my sales come from the Northern Wasatch Front, I usually make a FREE delivery run every other week to the North Ogden/Brigham City area.  Those delivery days are usually on a Sunday afternoon. Depending on your location and quantity ordered I might even be able to deliver right to your home/business.  You may need to bring some help if your order is more than a bunk or two.





My vehicle liability insurance company will allow me to deliver material within a 500-mile radius of Grace, Idaho.  Based on the current fuel price and other expenses (insurance, maintenance, licensing etc), my actual cost per mile driven  is around $0.85/mile.  I can schedule delivery to your home/business for my actual cost under most circumstances.  Remember, I have to charge the $0.85 per TOTAL miles (round trip) even though I only carry material on the outbound trip.  I can carry as many as 12 bunks per load but the freight price is the same whether I am delivering 1 bunk or 12 bunks since the truck’s MPG varies little either way.
