Composite Slate Shingles
Allegrone Construction Co. is currently installing composite slate shingles at the new office location in Lenox. These slate shingles are rated with an SRI Index greater than 78, contributing to LEED credits pertaining to the Heat Island Effect.
Incorporating a reflective roof or green roof will help to reduce cooling loads, thereby lowering energy consumption and making for a more comfortable space.
What is “SRI?”
SRI stands for Solar Reflective Index which measures a surface’s ability to reflect solar heat. Higher reflectivity is desirable, because it helps combat the urban heat island effect. SRI can range from zero to over 100, with darker surfaces closer to zero and lighter surfaces approaching 100.
