Structural and Performance Features

• Doors can impact a home or building’s energy performance, safety, security, accessibility and durability depending on…

- Insulation values- Fire ratings- Recycled material content- Frame strength- ADA guidelines- Impact Resistance


• Determine which features and performance characteristics are most important to each project

• Environment & Safety- ENERGY STAR, “green,” fire ratings, lock-position

• Performance Features

- Durability, weather resistance

• Aesthetics

- Aesthetics: color, profile, style

The door and frame must perform together

- Wood, steel and fiberglass doors are hung primarily in wood or steel frames

- Frames are susceptible to the same problems as the door material unless the frames are made of composite frames.

ASTM E 330

- Determines structural performance of doors by uniform static air pressure difference

- Look for a door that has passed this test




ASTM E 547- Determines resistance to water penetration under cyclic

static air pressure differences- Performance results will depend on the construction

quality and proper installation of the wall and its componentswww.astm.org/Standards/E547.htm



ASTM F 1450- Test for hollow metal, swinging doors in detention facilities –helps

determine how much abuse a door can handle. - Helps improve safety measures in detention facilities www.astm.org/Stndards/F1450.htm


Performance Features: Strength & Durability

ASTM E 1886

- Tests impact resistance of exterior fenestration products

- Identifies products that can withstand impact of large and small objects that would be similar to wind-borne debris during severe weather


ASTM E 1996

- Tests impact resistance of exterior fenestration products

- Identifies products that are able to withstand hurricane-like forces



Performance Features: Strength & Durability

www.2.iccsafe.org/states/Florida2001/FL_TestProtocols.htm

MR Credits 4.1 and 4.2: Recycled Content

- Percent of recycled content must be converted to cost of the product

- Projects with 10% of total materials cost with recycled content contribute 1 point

- Projects with 20% of total materials cost with recycled content contribute 2 points


LEED V3 for New Construction & Major Renovations

Example: Door has 10.4% pre-consumer recycled content Door costs $680 680 x .104 = $70.72 per door


LEED V3 for New Construction & Major Renovations

MR Credit 6: Rapidly renewable materials

- Projects with 2.5% of total materials costs from rapidly renewable materials contribute 1 point

Example- Door has 0.9% rapidly renewable

materials

- Door costs $680

- 680 x .009 = $6.12 per door

Learning Objectives






To have a complete entry system, you must also consider the door frame


Structural and Performance Features: Entry Systems

Closed Cell Technology

- Used to build door frames

- Creates stronger dimensions than wood door frames

- Will not absorb moisture

- Resists splitting and molding

- Wood frames rot, warp, crack, etc.

- Steel frames rust, dent, and transmit heat and cold

- Composite frames along with fiberglass doors resist rot, warp, crack, dent, heat or cold air transmission

Full length composite top and bottom rails and stiles of non-porous protection

- Prevents water from leaking into the door- Stops build up of mold


Structural and Performance Features: Composite Entry Systems
