3×4 Concrete Blankets

Powerblanket’s 3’x4’ insulated concrete blankets protect concrete pours from conditions that are too cold or too hot for optimal curing. Maintain hydration and successfully work through freezing winters and burning summers with these insulated curing blankets. Our patented design eliminates hot and cold spots by applying uniform full-coverage heat across the entire surface of the blanket. Use yours to thaw ground before pouring concrete and again after finishing for freeze protection. 3’x4’ concrete curing blankets come in three different thermal rating classes: Powerblanket – Designed for standard heating applications.
