Spec-Thermal®
Featuring Korfil Hi-R® & Korfil Hi-R-H from Concrete Products Group.
The Spec-Thermal™ Insulated Masonry system is a pre-insulated concrete masonry unit which provides significantly enhanced thermal performance over conventional masonry or foamed in place masonry.
The block and the insulation are combined at the block manufacturing plant prior to delivery to the job site.
- Provides guaranteed consistent insulation value
- Permits excess moisture to escape
- Allows easy installation of pipes, conduits, etc.
- Improves dewpoint
- Improves sound resistance
- Eliminates concern of shrinkage, toxic fumes or odors
- Improves the ability of blocks to resist wind driven rain.
- Can be used above or below grade
- No lost time or rework if inspection rejects the quality of on-site workmanship
- Work by other trades is performed with little danger of damage to insulation
- The block itself can be used as a bond beam
