BSI Testing

Marvin Windows and Doors have been tested to the following British Standards:

• BS 6206:1981 – Safety Glass for use in Buildings
• BS EN 1026, 1027 and 12211 - Weather Tightness Test on Marvin Clad Ultimate Sliding Sash Window

(previously BS 6375: Part 1: 1989 Performance of Windows)

Building Regulations

Marvin Windows and Doors comply with all of the relevant Building Regulations and in particular with recent amendments to the following building regulations:

• Part B: Fire Safety
• Part E: Resistance to the passage of sound
• Part F: Ventilation
• Part L1: Conservation of fuel and power in dwellings
• Part L2: Conservation of fuel and power in buildings other than dwellings
• Part M: Access and facilities for disabled people

American Standards

In addition, Marvin windows and doors meet stringent performance, environmental and manufacturing standards in the USA. These include:

Energy Star^®

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 (see below).

Window and Door Manufacturers Association (WDMA)

Marvin Windows and Doors meet or exceeds these standards, which relate to product performance on air and water infiltration and physical loads on the exterior and interior. This is key for pressure differentials in coastal areas. Marvin products are rated in accordance with the AAMA/WDMA 101/I.S.2-97 standard and certified in compliance with the WDMA hallmark program.

Design Pressure (DP)

A design pressure rating, as created by AAMA/WDMA 101/I.S.2-97, is a measure of the amount of pressure a window or door is designed to withstand when closed and locked. Each DP rating also establishes other performance factors such as structural pressure, water penetration and air infiltration. The higher a DP number a window or door has, the better the performance. As a frame of reference: DP 40 means that a window or door is tested to 60 pounds per square foot equal to a 155 m.p.h. (250 km/h) wind and must withstand water penetration under conditions equal to 8 inches (20 cm) of rain per hour driven by 50 m.p.h. (80 km/h) winds.

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 to each other. Some factors considered in creating an individual window or door's rating include: the U-factor (measuring heat loss), the solar heat gain coefficient, visible light transmission, and whole product performance (evaluating the frame, sash and glass in its entirety).
