Installation of Core-Fill 500 is fast and efficient, thanks to our experienced and certified crews at N-R-G Foam, Inc.
Typically, installation begins when the wall is complete. The mason can spend their time building the wall, and not have to stop production to pour the product into the cavities.
We install Core-Fill 500 by drilling a lineal series of 5/8″ holes into the mortar joint at approximately 4 foot from finished floor. When the foam is injected into the cavity, it flows throughout the wall. Horizontally, vertically and diagonally; the foam fills the ENTIRE interior structure of the wall. It even flows through the head joints of the blocks. This insures that all voids within the wall are filled by the foam. The foam will be filled to approximately 15 feet from finished floor, and then, depending on the wall height, another set of holes may be necessary to fill the wall completely to the top.
A distinct advantage of this product over all of the loose fill insulation choices is the fact that Core-Fill 500 dries to a solid. When cured, it has the consistency of a cross between sponge rubber and Styro-Foam. If the architect has a change order, it is easy to cut into the wall and remove sections of block without losing any of the insulation in the remaining block. Core-Fill 500 will never settle into any of the cavities. Once filled to the top, it remains at that level for the life of the building.
1. A series of small holes are drilled into the morter joints every 8″
2. The foam expands and flows through the entire cavity and web.
3. Holes are patched once the walls are properly filled.
