INVENTORY & PRICES                                             

                                   See bottom of page for DELIVERY SERVICES available.


August 15, 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.  I will have to visually confirm stock for any orders more than a few bunks.  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.
