Pembroke's Climate Data and Its Top-Rated Window Pros

What zone 5A means for a Pembroke window
Boston-Cambridge-Newton, MA-NH runs a January average near 31°F and climbs to about 74°F by July, a swing that adds up to roughly 5,309 heating degree days most winters, with 805 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Pembroke, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Pembroke's specific load is what tells you whether beating that floor is worth the extra cost.

Plymouth County's hail risk sits at Very Low and its wildfire risk at Very Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Pembroke; wildfire risk matters more for the frame material and nearby vegetation than for the glass itself.
Either way, it's a reasonable question to bring to a Pembroke installer before you settle on a product line.
