What zone 5A means for a Goffstown window

That load is the actual argument for paying up for a better U-factor in Goffstown, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Goffstown's specific load is what tells you whether beating that floor is worth the extra cost.
