Do I (or my builder) need special skills to build with Grid-WALL?
If your builder can run a saw and a level, he can build with Grid-WALL. It is forgiving of changes and errors until it is filled with concrete.
With so much concrete in the walls, how well does the insulation properties compare with traditionally built wood framed walls?
Grid-WALL’s combination of insulation, thermal mass and reduced air infiltration creates a structure that can reduce energy consumption over 50% as compared to traditionally built wood framed walls.
Will the styrofoam in the blocks burn?
Even though our blocks are made of 85% styrofoam, they will not support combustion.
Your blocks are square. How difficult is it to create curved surfaces or arches?
Grid-WALL is actually one of the easiest systems available to create any kind of curved surface. The curved design is drawn onto the blocks, the line is cut, and a thin piece of flexible fiberboard is inserted. This stops the flow of cement during the pour. Afterwards, the fiberboard and the material below it is removed, leaving perfect arcs.
The blocks can be cut to create custom angles quickly and easily, making any curved or angular wall possible with little difficulty. More information is available in the construction section
Does it take longer to build with Grid-WALL?
Erection time is cut with the Grid-WALL system. It goes up FAST and EASY.
What about termites?
Termites and other insects cannot eat or burrow into Grid-WALL.
Do I need to stagger the blocks like bricks?
No! But you MAY stagger them, if you prefer. Staggering the blocks helps to hold the wall in place as you are gluing it. Either way is acceptable. Align the seams so that the pour is uniform.
How much concrete does it take to fill the blocks?
It takes about 1 cubic yard of concrete to fill about 100 sq. feet of wall area.
Do I use #4 rebar in every hole?
All plans should be reviewed by an engineer. The usual placement is #4 rebar horizontally and vertically. In some areas you might use less, it just depends upon the engineering.
Do I need to put up wood strips to put up sheetrock?
No. Glue and screw sheetrock directly to Grid-WALL™.
What about Plumbing and Electrical? Can they go inside the walls?
Yes. Use conduit for electrical wiring and place the electrical conduit and the plumbing in the voids prior to pouring the concrete. More details and photos available here
