Construction and Materials
MMI Door offers a diverse range of exterior doors, designed to enhance both the aesthetics and functionality of your home. Their collection includes options crafted from fiberglass, steel, wood, and composite materials, as well as specialized fire-rated and glass door solutions.
Fiberglass Doors
MMI Door's fiberglass doors are engineered for durability and low maintenance. They provide the look of natural wood without the susceptibility to warping, cracking, or rotting. The construction typically involves:
- Construction: A composite or engineered wood core for strength and stability, encased in a molded fiberglass skin.
- Materials: High-density fiberglass skins that are resistant to dents and weathering. The skins can be embossed with wood grain textures to mimic the appearance of various wood species.
- Insulation: Often filled with a polyurethane foam core for enhanced thermal performance, contributing to energy efficiency.
- Finishes: Available in a wide array of colors and can be stained or painted to match existing architectural styles.
Steel Doors
Steel doors from MMI Door are recognized for their robust security and affordability. These doors offer a strong barrier against the elements and potential intruders.
- Construction: Typically constructed from heavy-gauge steel panels that are formed and assembled into a door slab.
- Materials: Galvanized steel for corrosion resistance. The door skins are often roll-formed or stamped to create various panel designs and decorative elements.
- Insulation: Similar to fiberglass doors, steel doors frequently incorporate a polyurethane or polystyrene foam core for insulation.
- Security Features: Often include reinforced lock areas and sturdy construction for enhanced security.
- Finishes: Available in factory-applied finishes that are durable and resistant to chipping and fading.
Wood Doors
For a classic and elegant appearance, MMI Door provides wood exterior doors. These offer natural beauty and can be customized to suit traditional and contemporary designs.
- Construction: Can range from solid wood construction to engineered wood cores with solid wood veneers. Panels and stiles are typically joined using mortise and tenon construction for durability.
- Materials: A variety of wood species may be used, including hardwoods like oak, mahogany, or maple, as well as softer woods depending on the specific product line and desired aesthetic.
- Design Options: Offer a wide range of design possibilities, including intricate carvings, multiple panels, and the integration of glass lites.
- Finishes: Require finishing (staining or painting) to protect the wood from the elements and enhance its natural beauty.
Storm/Screen Doors
MMI Door's storm and screen doors provide an extra layer of protection and ventilation for your home.
- Construction: Typically feature a lightweight frame, often made of aluminum or vinyl, housing interchangeable screen and storm panels.
- Materials: Frames are commonly constructed from extruded aluminum for strength and weather resistance. Screens are usually made of fiberglass or aluminum mesh. Storm panels are often made of glass or durable plastic.
- Features: Many models include self-storing glass or screen panels for easy conversion between ventilation and protection. Other features may include built-in closers and decorative hardware.
Glass Doors (Including Entry Doors with Glass Lites)
MMI Door incorporates glass elements into many of their exterior door offerings, from full glass entry doors to doors with decorative glass lites.
- Construction: The construction varies depending on the door type. For entry doors with glass lites, the glass is typically sealed within the door panel using a frame or beveled edge. For full glass doors, the glass is often the primary structural component, supported by a frame.
- Materials: Glass can range from clear tempered glass for safety and durability to decorative options such as stained glass, etched glass, or glass with intricate metal inserts.
- Insulation: When incorporated into entry doors, insulated glass units (double or triple pane) are often used to improve energy efficiency.
Fire-Rated Doors
For applications requiring enhanced safety and fire resistance, MMI Door offers fire-rated doors.
- Construction: Engineered with specialized core materials and construction techniques to meet specific fire-resistance ratings.
- Materials: Core materials may include mineral composites or fire-retardant treated wood. The skins and framing are also designed to contribute to the fire rating.
- Ratings: Available in various fire-resistance ratings (e.g., 20-minute, 45-minute, 90-minute) to comply with building codes.
