8′ Low Income Homes 3.5 Multiplier (1,000 sq ft house x 3.5 = 3,500 sq ft of PANELS)
9′ Mid Level Homes 3.6 Multiplier (1,000 sq ft x 3.6 = 3,600 sq ft of PANELS)
10′ High End Homes (high ceilings/roofs etc) 3.7 Multiplier (1,000 sq ft x 3.7 = 3,700 sq ft of PANELS)
Above 10′ will be difficult, highly customized plans will have a 4.0 multiplier
Rough Guide To Estimating Costs
Step 1 Provide the quantity of panels for the walls & the roof/ceiling.
Step 2 – Mesh Accessories – You take the mesh multiplier (0.63) and multiply the number of total sq ft of panels for the the project to account for the total amount of accessory mesh that will be needed. This is a rough approximation to be used for pricing proposed only. (ex. 1,000 sq ft x 0.63 = 630 sq ft of Accessory Mesh)
Step 3 – Pick out Multiplier (Cost of panels & mesh + delivery to site) example at $8, multiplied by the number of sq ft of the project (1,000 sq ft x $8 = $8,000 cost for panels & mesh accessories) & delivery/freight cost. This price is a rough approximation including cost of the panels, accessory mesh, and freight/delivery to job sight.
25% – Cost of panels, mesh accessories & shipping delivered to build site
25% – Cost to install Dry trades (installing the panels), door jams, framing window openings, placing all rebar, removing foam forming, shoring etc. Any carpentry and everything ready to pour or spray/apply cement.
50% – Cost for all the Wet trades – applying Portland cement skin over panels (by hand, pneumatic application or by shotcrete)
Knowing the Price per sq ft – Approximation Only
Another method is knowing the price per sq ft of the panels cost multiplied by a rough approximation cost to install. It is very important you must keep in mind price variance between geographic locations as well as what you think you will be able to build/sell the panels for. (For example, $25 per sq ft for 1,000 sq ft house would be approximately $25,000)
Note: Unit cost will vary per design of the structure and type of architecture chosen. Also factoring into unit cost will be interior and exterior finishes as well as geographical variables (depending on the state/country/county) including average labor cost, equipment available in the area, using pumps, shoring, scaffolding etc.
Panel Product Description
All panels are four (4) feet wide with a MINIMUM height of 8′ for each panel.
The panels can be cut every 8″ (ex. 8’8″, 9’4″, 10’8″. 11’4″ etc. ) to a MAXIMUM length of 40′. The foam thickness varies starting at 2″, 2.5″, 4″, 5″.
The wire mesh is 5/8″ off the surface of the foam on each side of the surface of the panel. **Adding 1.25″ to the foam thickness will equal the full panel thickness from wire to wire**.
The 9 gauge cross wire is pushed diagonally through the foam & welded to the 2″x2″ welded wire mesh, every 4″ , this creates 12 strusses in each panel.
Description of Accessory Mesh
Flat mesh – used to connect all panels together this is required on both sides of each panel (doubling the length of each panel will give you this quantity) as well as at ALL diagonal corner surroundings each window and each door opening. Allow 4 pieces of 1’x4′ Flat Mesh. They will be cut in half at 1’x2′ pieces and 4 pieces will be placed on each window (diagonally at a 45 degree angle at all 4 corners above & below each window) on both sides of the wall.
Allow 2 pieces, 1’x4′, flat mesh for each door opening, and place diagonally above door openings on each side of the wall.

6″ Interior Angles
1′ x 4′
12″ Exterior Angles
2′ x 4′
2′ x 4′
Interior Corner Angles – 1’x4′, the same size as flat mesh only these are bent at a right angle and placed at all interior inside corners. These angles will be connecting the panels together. Measure the length in lintel ft of the corner and divide by 4′. This will give you the quantities of 1′ x 4′ 6″ angles. .
Exterior Corner Angles – 2’x4′ Exterior corner angles – Used on all exterior corners. I also use them under and above panel floors and ceiling. I also order extra and will sometimes cut them in half, length wise, and use them for flat mesh. They are 2′ wide 12″ in each direction. They are this width (12″ wide) so that when they are placed upright they cover the raw edge of the foam and add strength, and 4″ length, to the corner.
U-MESH – Use depending on the engineering. Use to wrap any raw edge where foam is exposed, around window openings, parapet caps on tops of the walls, the ends of roof over hangs, the bottom side of lintels or beam, around garage door opening etc.
Trade tip, use two pieces of 6″, 1’x4′ angles in place of the U-MESH. This is all figured by lintel ft and divided by 4 ft. This gives you the quantity of U-MESH. If using 6″ angles be sure to double the quantity of pieces. ***The 6″ angles are much easier to ship and fit tighter to the panel***
COST , QUANTITY and SHIPPING
Shipping of panels & MeshThe panels are usually shipped on open flat bed trucks, 43′ trailers or longer, depending on panel lengths and foam thickness. The approximate amount of panels that can shipped will fall in the between a minimum of 6,000 sq ft and a maximum of 8,000 sq ft at a cost of approximately $1.00 per sq ft, depending on distance shipped.
How to Order When placing panel orders keep the panel quantity at a minimum of 10 each per size, for ease of shipping, and resetting the machine to make custom small cuts or quantities.
When ordering roofs & ceilings/panels you will need full length panels. Also on the walls it is best to order & use full length panels.
