Panel

Polyurethane Insulation: Steel + Insulation + Steel
State-of-the-art polyurethane insulation is foamed between the door's steel skins and expands to fill 100% of the door's interior space. This delivers the industry's best insulation efficiency and provides for maximum structural integrity, strength and soundproofing.

Polyurethane
Climate control, reliability, durability-- our Dafayardr polyurethane insulated steel overhead doors have it all, providing excellent temperature control, energy efficiency and long-lasting service for a wide range of applications, such as firehouses, warehouses, and municipal buildings.
With today's high energy costs, insulation in a garage door is just as valuable as anywhere else in your home.Even more people use their garage as a work place or social gathering spot, and not just storage.
A polyurethane insulated door might look thinner but actually offers a much higher insulation R-value. That is because of the way the insulation expands during the manufacturing process to tightly fill the cavity between the two steel panels as it chemically bonds to the skins of the door.
Not only does this make the door better insulated, it also makes the door incredibly strong and helps lessen noise while the door operates, as is common with single sheet metal doors that have no insulation or even polystyrene insulation.
Panel finish(wood grain , stipple are available)
deeply-embossed, Dafayard offers a deep, rich wood grain pattern that looks remarkably like real wood and stipple finish, unlike any other garage door on the market.

This exceptional line of overhead doors incorporates a thermally-broken section design for superior weather protection. 0.326-0.45 mm exterior steel skin and 0.326-0.45mm interior steel skin filled with foamed-in-place polyurethane creates an extremely rigid barrier. A continuous section joint seal that impedes air infiltration additionally enhances this door. Available in customization factory finish paint colors and a diverse collection of window options, this door will add value and appeal to your home for years to come.
    
Thermal Break & Air Seal
Thermal break and air seal prevent heat loss from metal-to-metal contact between inside and outside surfaces.
Weatherseal
To help keep out wind and rain, all Dafayard overhead doors feature a vinyl bottom weatherseal attached to a sturdy aluminum or PVC bottom profile.
Joint Design
Tongue & groove section with continuous foam thermal break
Window designs
Don't think you want windows in your garage door? Think again!
They allow natural light into the garage that can make a gloomy garage interior much more appealing during the day. If you want to be able to look out your garage door, have the windows put in the third section from the bottom. If you don't want to look out the door, but want the beauty and natural light of windows, then have them put in the top section of the door.
Hardware
14 gauge hinges, commercial 10 ball steel rollers, 10,000 cycle torsion springs
Lift Handles and Pull Ropes
A lift handle is a handle attached to the door that allows you to manually open or close a door. A pull rope performs the same function and is usually attached to the bottom bracket in the lower corner of the door.
The lift handles and pull ropes are intended for use with a door that is opened and closed by hand.
Photocell and Sensing Edges
Photocell are sensors that are mounted about 5 to 6 inches off the floor on both sides of a garage door. These sensors operate with a garage door opener and send an invisible beam across the door opening. If that beam is broken while a motorized door is closing, the garage door opener will cause the door to reverse direction to the fully open position.
A sensing edge is attached to the bottom edge of a garage door. When this sensor contacts an obstruction during the closing of the door, the opener will cause the door to reverse direction to the fully open position.
Remote Controls
Garage door openers are usually operated by a wall-mounted push button, a hand-held remote control, or a keyless entry pad that requires you to enter a numerical code.
Limited Warranty
Good warranties offer you the peace of mind that the manufacturer is confident about the design and construction of its doors, and will back that up should the door happen to fail for reasons noted in the warranty. We offer 5-year paint / one-year material & workmanship.

Garage Door Safety

Safety is a concern with any product. The garage door is the largest moving object in the typical home. Because of its size and complexity, it should have as many safety features as possible. The following garage door parts can be dangerous. Familiarize yourself with these parts and know how to treat them safely.
Section Joints
This is the area between garage door sections.
People have been injured by attempting to close a door by placing their fingers in an open section joint and pulling down on the door. Some garage doors, like our finger-protection doors feature a design that pushes fingers out of harm's way should they accidentally be placed too close to a closing door.
As a safety precaution, however, never attempt to place your fingers in the section joint.
Corner Brackets
The corner brackets are the two brackets that are attached to the lower left and lower right corners of the garage door. The cables that lift your garage door are typically attached to these brackets.
Since these cables are under high tension, the brackets could fly dangerously when disconnected. Only an experienced technician should service these brackets.
Torsion Springs
Garage doors are typically balanced either by torsion springs. Torsion springs are usually mounted above a closed door, parallel and horizontal to the top section of the door. They provide lifting power for the door by winding and unwinding while the door is opened and closed.
The torsion spring is under high tension and requires special tools for adjustment. Because of the high tension, the torsion spring, and any part associated with the counterbalance system, should be adjusted only by a professional. These parts include: the springs, the cables, the corner brackets attached to the cables, the cable drums, and the center bearing bracket that holds the torsion spring shaft.
Garage Door Openers
A garage door opener is a separate product from a garage door. Openers are electric motorized devices that open and close garage doors.
Most garage door openers include an internal reversing mechanism that causes the the door to reverse when it hits an obstruction. However, garage door openers with inadequate or poorly maintained reversing mechanisms have caused injury and even death to children who are caught underneath motor-operated garage doors.
Lift Handles and Pull Ropes
A lift handle is a handle attached to the door that allows you to manually open or close a door. A pull rope performs the same function and is usually attached to the bottom bracket in the lower corner of the door.
The lift handles and pull ropes are intended for use with a door that is opened and closed by hand. But when an opener is attached to the door, the pull rope should be removed. Otherwise, they can snag or hook on people or loose clothing while the door is being opened by the operator. If you have a power outage and need to manually close your motor-operated door, don't close the door by placing your fingers between the door sections.
Photocell and Sensing Edges
Photocell are sensors that are mounted about 5 to 6 inches off the floor on both sides of a garage door. These sensors operate with a garage door opener and send an invisible beam across the door opening. If that beam is broken while a motorized door is closing, the garage door opener will cause the door to reverse direction to the fully open position.
A sensing edge is attached to the bottom edge of a garage door. When this sensor contacts an obstruction during the closing of the door, the opener will cause the door to reverse direction to the fully open position.
Remote Controls
Garage door openers are usually operated by a wall-mounted push button, a hand-held remote control, or a keyless entry pad that requires you to enter a numerical code.
Small children have been seriously injured by playing with the remote controls of motor-operated garage doors. Running under a closing door can be a deadly game. Do not let children play with or use the push button or any remote controls for your door. Keep all such controls out of the reach of children.
