Interior Insulation by ER Systems

Energy Conservation - Energy Savings

R-Tech Insulation located in Cromwell Minnesota.
We've been insulating homes and businesses since 1998.

We specialize in ER Systems Close-cell Polyurethane Insulation

ER Systems Polyurethane Foam provides the highest performance of any insulation per inch:

• Highest R Value
• Air Infiltration Control
• Air Convection Control
• Moisture Control in Building Cavities

Air Quality

Limiting the movement of allergens, toxins or other harmful airborne contaminants greatly improves the indoor air quality of your home. Because polyurethane foam insulation is 90% close-cell, air infiltrations limited and in most cases completely prevented. Polyurethane foam also prevents moisture movement and condensation, this in turn limits the growth of indoor contaminants such as mold, mildew, and fungi.

Energy Conservation

70% of heat loss from conductance is stopped by the first one inch of spray polyurethane foam. The second inch stops approximately 90% of heat loss and the third inch will prevent 95%. Polyurethane insulation also prevents nearly 100% of heat loss through air infiltration convection with the first one-fourth inch, all this translates into 20-40% energy savings.
