Interlock’s (IR) reflective surface can help reduce your attic's temperature during summertime heat, saving you up to 25% on your cooling costs†.

The Alunar Coating System is a full 70% PVDF coating incorporating a unique acrylic blend and 70% polyvinylidene fluoride (PVDF). Designed as a premium finish to provide outstanding color stability, gloss retention, exceptional abrasion resistance, scratch resistance, and chemical resistance. Alunar is also formulated to be used in coastal environments. This high-performance coating is engineered to reduce the carbon footprint and lower the heat island effect.

Alunar uses infrared (IR) reflective or “cool” pigments to comply with industry energy conservation initiatives. Using “cool” pigmented coatings can help reduce energy consumption for conditioned living spaces.
