The Challenge for High Performance Parking Garage Doors
May 19, 2017
Parking garages are known to be very challenging applications for garage doors for several reasons: high cycle demands, high risk for vehicle impact and restricted headroom. Traditionally, these problems have simply been accepted as part of the nature of the application and sectional garage doors provided a low-cost way to easily close the opening. Additionally, the challenge of low headroom was nicely addressed by a section door that retracts onto horizontal tracks that can be installed in minimal headroom.
However, a traditional sectional door proves to be low-cost only at initial installation. With a relatively slow opening speed, the sectional door is prone to vehicle impacts as vehicles move impatiently in and out of the parking garage. Once a door section is damaged, the door is out of operation and a security guard is often required to monitor the entrance until expensive emergency door repairs services can be brought in to install replacement sections. Over time, the additional cost of hiring security, replacement door sections and installation service adds up and the initial savings of a low-cost sectional door are offset by ongoing high maintenance costs.
For several years now, property and maintenance managers tired of downtime and rising maintenance costs related to their sectional parking doors recognize the value provided by a high performance rubber door. High performance door (HPD) manufacturers, including TNR Doors, began to refine the rubber door design, developing door models specific to the urban parking environment. The biggest challenge for adapting an HPD rubber roll-up door is to fit the door header into the typically restricted headroom of a parking garage with its low ceilings. Early designs, such as TNR’s springless model HDP, succeeded in maintaining high speed while still fitting into as little as just 18 inches of headroom. Additionally, the rubber roll-up door with a knock-away bottom bar design provides fast and easy resetting of the door after an accidental vehicle impact. Resetting requires no special skills, standard tools and only standard fastener replacement parts, thereby reducing the downtime and maintenance costs involved.
The evolution of HPD roll-up doors into parking garages continues as a growing numbers of property managers see the benefits of the application in their industry. Consequently, more HPD manufacturers have developed and refined products to compete in this new market segment, limited only by the amount of minimum 18 inches headroom required by most HPD parking garage doors.
Recognizing that there was further opportunity in even tighter spaces, TNR Doors has recently developed a new additional door model – the Extra Low Headroom – for the parking garage market segment, creating a new product family – Springless Low Headroom PARK-KING™ DOORS. Now, in addition to the HDP model that fits into 18 inches of headroom, the new Extra Low Headroom (HDLH) model uses a patented design allowing it to fit into as little as 13 inches of headroom! The same time-proven rubber curtain with CurtainLok™ and NewGen® guides and high cycle drive system are combined with a new bottom bar design utilizing pivoting know-away arms that allows for a very low profile door header assembly.
The challenge of parking garages with very restricted headroom being limited to only sectional or rolling steel doors has been met. The new model HDLH proves to be a sound choice, realizing a favourable return on investment and paying back with reduced maintenance and downtime costs.
