Water Repellent Cavity Insulation

A bag of insulation will fill the cores of approximately 16 standard 8 inches concrete blocks or approximately 14 square feet of wall area.

To avoid waste seal up all openings through which the insulation might flow (pipes, wiring, etc.)

For best results lay only three of four courses of block, then fill the cores. Isulation may be poured directly from the bag into the cores or through a wood or metal hopper placed on top of the block. The insulation is emptied into the cores by sliding the form along the top course of block.

No rodding or tamping is necessary.

Blows into walls and attics. Pours over existing insulation. Can be used with firebrick. Perfect for chimney and flue liners.
