Collingswood, NJ Climate Specs + Top-Rated Window Installers
Collingswood sits in IECC climate zone 4A, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Collingswood on this site, so Google Maps supplies the 10 ranked names you see below. Checked September 2026.

Collingswood's climate zone, in plain terms
Philadelphia-Camden-Wilmington, PA-NJ-DE-MD runs a January average near 33°F and climbs to about 77°F by July, a swing that adds up to roughly 4,858 heating degree days most winters, with 1,171 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Collingswood, separate from anything a brochure claims.
Zone 4A's requirement is the floor; Collingswood's specific load is what tells you whether beating that floor is worth the extra cost.
