PERFORMANCE RATING INFORMATION AND EGRESS CODE

As you flip through this catalog, you’ll see different ratings on the performance of our windows and doors. Here’s some brief background information:

WDMA STANDARDS

The Window and Door Manufacturers Association (WDMA) in conjunction with other organizations in the industry has developed standards
that make it easy to compare windows from different manufacturers, testing product performance regarding air and water infiltration, as well
as physical loads on the exterior and interior (very important when you consider the pressure differentials that can occur in coastal areas,
as well as forced entry resistance). Marvin products are rated in accordance with the AAMA/WDMA/CSA 101/I.S.2/A440-05, AAMA/
WDMA/CSA 101/I.S.2/A440-08, or AAMA/WDMA/CSA 101/I.S.2/A40-11 Standards are certified in compliance with the WDMA
Hallmark program.

PERFORMANCE GRADE (PG)

A Performance Grade (PG) Rating is given to products that comply with and attain a specific level of performance in accordance with current
testing standards/specifications created by AAMA/WDMA/CSA standards. Once all applicable testing has been successfully completed
for air infiltration, water penetration resistance and structural loading which also includes load deflection, ease of operation and forced entry
resistance testing, a PG rating is given. The higher a PG number has, the better the performance.

NFRC

Marvin Windows and Doors is a founding member of the National Fenestration Rating Council, an independent, non-profit organization that
has established an energy performance rating system for accurately comparing different window and door products. Some factors considered
in creating an individual window or door’s rating include: the U-factor (measuring heat loss), the solar heat gain coefficient, and visible light
transmission, evaluating the frame, sash and glass in its entirety. See Marvin.com/support/energy-data for NFRC values by product.

ENERGY STAR®

The U.S. Department of Energy and the U.S. Environmental Protection Agency created this standard to help consumers identify products that
reduce energy use. Windows and doors that qualify for ENERGY STAR are twice as efficient as an average window produced ten years ago
and must be rated, certified and labeled according to the NFRC. To get current energy data, go to energystar.gov.

EGRESS CODE

International Building Code - 2003 and 2006 Section 1009 Emergency Escape and Rescue.
1026.2 Minimum size: Emergency escape and rescue openings shall have a minimum net clear opening of 5.7 sq ft (0.53 m2). Exception:
The minimum net clear opening for emergency escape and rescue openings on the ground level at grade is 5.0 sq ft (0.46 m2).
1026.2.1 Minimum dimensions: The minimum net clear opening height dimension shall be 24 inches (610 mm). The net clear opening width
dimension shall be 20 inches (508 mm). The net clear opening dimensions shall be the result of normal operation of the opening.
1026.3 Maximum height from the floor: Emergency escape and rescue opening shall have the bottom of the clear opening not greater than
44 inches (1118 mm) measured from the floor.
1026.4 Operational constraints: Emergency escape and rescue openings shall be operational from the inside of the room without the use
of keys or tools. Bars, grilles, grates or similar devices are permitted to be placed over emergency escape and rescue openings provided the
minimum net clear opening size complies with Section 1026.2 and such devices shall be releasable or removable from the inside without the
use of a key, tool or force greater than that which is required for normal operation of the escape and rescue opening. Where such bars, grilles,
grates or similar devices are installed in existing buildings, smoke alarms shall be installed in accordance with section 907.2.10 regardless of the
valuation of the alteration.
Code restrictions may vary depending on your local building codes.
