Yes, Virginia, there is a Santa Claus, and he would recommend a product everyone can agree on: PermaBASE CI® Insulated Cement Board. A win-win for architects and contractors alike, it’s sure to bring peace to your project jobsite. And with the cold winter months ahead, PermaBASE CI will keep all the warmth inside the walls.

While contributing to Energy Code compliance and providing NFPA 285 approvals, PermaBASE CI is a composite insulated cement board that combines the strength and features of PermaBASE® Cement Board with rigid insulation to create an ideal substrate for exterior finishes.

Continuous insulation moderates temperatures inside the wall cavity, reducing the potential for convective heat loss and increasing the insulation value of the wall system.

Not all insulations are created equal. Less efficient solutions require more thickness of insulation material to achieve the same R-Value as PermaBASE CI. 

PermaBASE CI is a great product to specify for residential, multi-family and low-rise commercial applications. It will help lower utility costs, provide better thermal comfort and reduce the likelihood of trapped moisture over conventional construction.


According to Tony Fuller, Product Manager – Cement Board, the demand for improved thermal efficiency continues to rise and PermaBASE CI is well-positioned to deliver outstanding performance in a cost-effective solution.
