General: The PRIME/plus window system is to be installed on the interior casing of the existing energy inefficient prime window. It is designed to work in tandem with, but independent of, the prime window.
All inserts are to be fully removable without detaching expanders or main frame members from the opening.
The system shall be designed in such a manner that its performance characteristics shall meet the follow:
A. Air infiltration: Stand alone air infiltration rates shall not exceed the following air infiltration levels when tested at 1.56 psf (25 m.p.h. - equivalent) er ASTM: E283-73.
Unit Per Lineal
Window Type Size Ft. of Crack
2200 non-ventilating (1 lite) 54" x 76" .23 c.f.m.
2100 double hung (2 lite) 45" x 76" .164 c.f.m.
2000 slider (2 lite) 72" x 60" .199 c.f.m.
1200 non-ventilating 48" x 48" .158 c.f.m.
1000 slider (2 lite) 60" x 48" .214 c.f.m.
B. Combined U-Value: Combined U-Value shall not exceed .59 Btu/hr/sq. ft./ °F when tested by use of heat flow meter methods at a minimum of 18 °F inside/outside temperarture differential.
C. Uniform Load: The inside system shall show no damage when subjected to a load of 15 psf exterior and 15 psf interior when tested per ASTM E 330-70. The test sample shall be 42 x 60 inches, with two inserts (2000 series).

2000 Series: Any 1/8, 3/16, or 1/4 in. material listed on glazing chart (see glazing chart).
Expanders shall be further attached with mechanical fasteners on 12 in. centers. Any gaps between expanders and the casing shall be filled with Sonneborn® Sonolastic® sealant or equal.
The main frame shall be true and square inside the opening without regard to out-of-square and run-out in the casting.
All inserts must close smoothly and tightly. Meeting rails between inserts must seal completely upon closing.
All system glazing materials, as well as the inside glazing surface of the orginal prime window, shall be left clean.
Where necessary, appropriate matching touch-up paint shall be used to repair scratches to painted surface.
