Q. What is the difference between a Roller Door / Sectional or Panel door / Tilt Door?
A Roller Door rolls up vertically in the opening around a circular drum wheel. When open the majority of the roll usually sits above the door opening.
A 'Sectional Overhead door' or 'Panel door' is made up of horizontal panels, which have wheels that slide up along tracks section by section to lay parallel with the garage roof when open. Some panel doors fold upwards along a vertical track
A Tilt door is made in one rigid piece designed to enclose an entire opening pivoting in the garage opening, supported by J-Type or T-Type Hardware. Its movement can be controlled within horizontal and vertical track, horizontal track, or vertical track.
Q: Why does a Sectional Overhead or Panel vehicle access door have a gap to the substrate structure?
A - It is imperative that there is sufficient working clearance to prevent panels from scraping the substrate structure which could damage the moving panels and impact on the operational efficiency of the door. The working clearance should be sufficient to prevent debris from being caught between the panel face and substrate structure potentially causing damage to moving panels and impacting on the operational efficiency of the door. The gaps do not provide an entry pathway at vertical door edge into the garage as the door hardware is tightly fixed to the substrate structure.
The Australian Garage Door Association recommends provision of adequate gaps for sectional overhead and panel doors and has observed that different manufacturers in Australia, Europe, UK and USA have different gap tolerances to ensure their product performs optimally in situ and provides long product life.
Additionally these gaps provide Architectural shadow-line effect but can be disguised by brush seals.
Q - Do I need a Door lock?
A - It may not be necessary to have a lock If an electric garage door opener has been or is going to be installed on your door. Newer electric openers function as the lock, making it unlikely that someone would be able to lift your door from the outside. If you have an older opener, check to see if your door can be lifted from the outside. It is not recommend that you install a lock with an opener, because someone accidentally may try to open the door automatically when it is physically locked, possibly causing damage. A lock should be considered, if you do not intend to have an automatic opener.
Q - What safety features should come with a garage door?
A - The garage door is usually the largest moving item in your home and consequently, failures or misuse can cause serious injury. Consequently, we recommend you follow our garage door safety tips in the Consumer Safety Leaflet available under the safety tab on this web site. In addition, there are types of doors and accessories that improve safety. Many door manufacturers have included in their range a 'pinch free' design that stops fingers being trapped on both the inside and outside of the door. As an options extra, we recommend fitting an infra red beam that stops the door closing when the beam is broken. This is a great safety feature if you have small children or animals that run in and out of the garage. More information is available in the December 2011 Newsletter.
Q - Why should I use a professional installer?
A - AGDA firmly believes that the installation of a garage door is not a do-it-yourself job. A garage door is the largest moving object in your home and because of the large number of small parts; its installation is highly technical. Connecting the springs can be particularly dangerous and proper installation is critical to the performance of your door. One of the other services a Professional Garage Door Technician can provide is the disposal of your old door, if you are replacing a door. Professional Garage Door Technicians can typically install a door in a few hours and are careful to make sure safety requirements are met. Installations by most homeowners typically span several days and cause much frustration. In addition, incorrect installation can void certain warranties. Please refer to the Consumer Safety Leaflet available under the safety tab on this web site
Q - What type of care and maintenance is required for my garage door or opener?
A - A garage door is usually the largest moving part in your home and needs regular maintenance in order to prolong its life and operate safely. Please refer to the maintenance instructions that came with your door and ensure you have your garage door serviced annually. Also please refer to the Consumer Safety Leaflet available under the safety tab on this web site.
Deactivate your electric garage door opener every three (3) months by disengaging it, as described in the operating instructions. Operate the door manually in order to determine how easy it is to open. Remember that an electric garage door opener is only meant to work as a substitute for human strength. You must therefore avoid placing any unnecessary strain on it. If the door is hard to open when operated manually, contact a Professional Garage Door Technician. If the springs are not set up correctly you may find the door very heavy to lift or the springs may need readjusting as a result of some tension being lost through time. This sort of problem may result from a decompressed spring, a warped track, a loose cable or one of the springs or a couple may have snapped which may be visibly noticeable. If so equipped, it is a good idea to check the photoelectric protection system as well to make sure it is working properly.
Q - How do I exit my property if there is a power failure?
A - Disengage the opener to switch your door/gate into manual mode. Refer to your instruction manual for further information. Once you have exited the garage or property you can lower the door or close the gate and re-engage the opener to securely lock up.
Q - What Safety labels should be on or near my door?
A. AGDA has produced a newsletter on this topic and it is available from this link Newsletter#4.
Q - What impact will changes in the wind load design requirements and BCA mean for consumers?
A. The operative standard in Australia and New Zealand has been updated as a result of changes in the wind load design requirements. The Standard AS/NZS 4505:2012 has been called up in the Building Code of Australia effective for new construction from May 2013 in Cyclone Category Areas C and D. The impact for consumers in high wind areas will be the need to have garage doors designed to comply with the wind load requirements which are drafted to maintain the structural integrity of the whole building envelope and minimise the risk of failure under wind load and the possibility of objects or building pieces becoming projectiles and causing impact damage. As a result designed doors may cost a little more than standard doors.
Q. Why does the door or gate reverse before it completes the close cycle?
A. The opener is sensing an obstruction – this could be a physical object in the doorway or perhaps the door is binding at that point of its travel. Also the force margin might need to be adjusted and retested. If there is no physical obstruction and adjusting the force margin has not resolved this issue, please contact a Professional Garage Door Technician.
Q. Sometimes my door opens by itself?
A. This could be radio frequency interference, a faulty transmitter or perhaps someone in your vicinity has their transmitter accidentally coded into your door. Construction equipment operated by wireless transmission, baby monitors and other like equipment have been identified as possible causes of radio frequency interference,
