Frequently Asked Questions About Rubber Doors


Rubber Doors Frequently Asked Questions

What are the benefits to a Rubber Door?

The benefits of rubber doors are safety, durability, and savings. When compared to operations that use steel doors, facilities with rubber doors have fewer injuries on average, limited repair needs due to being impactable, and lower energy and maintenance costs.

Safety

The springless operation design of rubber doors reduces injuries associated with torsion springs found on steel doors. At PerforMax, all our doors come standard with Inertia Brake and Reflective Photo Eye safety features. The Inertia Brake stops your door from free falling if power supply is interrupted. The Reflective Photo Eye uses an infrared beam to detect movement when the door is closing. Once the beam is interrupted, the door will roll back up.

Durability

Rubber doors can withstand harsh industrial environments and can take a hit, literally. Whether from heavy machinery, trucks, or forklifts, our door will take the impact and easily reset back into the guides.

Savings

A rubber door from PerforMax will cut down energy and maintenance costs. The quick opening and closing speeds lead to less time for the energy in your building to escape and ultimately lower heating and cooling bills. You’ll also see a reduction in maintenance and repair costs, as rubber doors have fewer wear parts and can take an impact without being damaged. A maintenance manager from Fedex told us their maintenance costs went from $50,000 a year, down to $0. For a more detailed look at rubber vs steel doors, see our post about the advantages of rubber doors.

Are rubber doors expensive?

Rubber doors have a higher upfront cost than traditional roll up steel doors but offer a significantly lower lifetime cost. Much like solar panels, investing in rubber doors will save you money in the long run. Rubber doors offer lower maintenance costs and reduced energy costs compared to rolling steel doors.

Can you add windows to a rubber door?

Windows can be added to rubber doors to improve visibility in your facility. The standard size of vision windows for rubber curtain doors is 14”x14” and depending on the size of your door, two or more can be added windows to your rubber curtain. Check our Photo Gallery to see some examples of doors with vision windows installed.

How does a rubber door affect energy savings?

Rubber doors reduces energy costs in two ways. A rubber roll-up door can have up to 4x the opening speed of a rolling steel door resulting in less energy lost during operation. It also provides a better seal from the exterior. The less air infiltration into your facility, the less you lose on heating and cooling costs. We’ve had a client let us know after installing our door, their energy costs were cut by 30%.

Warranty

What’s your warranty policy?

> Limited Lifetime Warranty on the rubber curtain > 2-year warranty on the motor > 1-year warranty on all parts and components Our fully detailed Global Warranty Policy can be found here

Does the curtain tear easily and is it covered under the warranty?

We do not commonly see reports of tears in our rubber doors. If a tear does start to form, it’s typically found around the bottom safety edge or near the sides once pushed out of the guides with excessive force. These tears are covered under the Limited Lifetime Warranty.

Does the seam on the curtain come apart?

We’ve never seen the seams coming apart on our curtains, but just in case they do it’s covered with the warranty.

Security & Ratings

How thick is a rubber door?

The curtain is ¼” thick with a 17.4 oz 1 ply fabric polyester at 1090 x 700 lbs./in break strength reinforcement.

Can you cut through a rubber door with a knife?

Rubber doors are reinforced polyester fabric and are not easily cut through. It’s designed to be difficult to puncture and would take real effort and an extremely sharp tool to cut through enough to be able to even crawl through.

How secure is a rubber door?

Our breakaway system is great at handling impact without damage to the door, but it would be impossible to push the door out manually. An intruder could even take a sledgehammer to a rubber door and not have any luck. Attempting to lift the door up from the bottom wouldn’t work either thanks to the guides and locks in place. Rubber doors are a very secure option for any type of facility. We’ve even installed our rubber door in a prison, where security is crucial.

What is the R-value of a rubber door?

Unlike fiberglass and steel, rubber is a natural breathable material, so it technically doesn’t have an R-Value. Rubber is a natural insulator however, meaning it is not easy for energy to pass through. Rubber overhead doors have no slats for air to escape through and have an airtight seal to keep your facility well-insulated.

What is the wind rating for rubber doors?

The standard wind rating on a PerforMax rubber door is 88MPH or 20PSF. For environments with harsher winds, we offer a windpackage with our door to strengthen the wind rating.

How often do rubber doors require maintenance?

Rubber doors are your low maintenance solution. There are just three components to check depending on how often the door is used. Bearings should be greased every 6 months to 1 year, windlocks should be tightened every few months, and batteries in the safety edge transmitter should be replaced every few years.

What is the typical application where the rubber doors are installed?

Rubber doors are designed to suit applications with high cycle use, harsh industrial environments, and high damage operations. They are also ideal for facilities that require fast opening times. From simple loading dock doors to transit authorities, to extra-large openings for heavy industries like mining, rubber roll-up doors can be used for any application.

If there’s no springs, how can a rubber door function in a power outage?

All direct drive units on rubber doors are equipped with an emergency manual override, either a manual crank or chain hoist that allows the door to open and close during a power outage.

Where are PerforMax rubber doors made?

We proudly make our doors right in our hometown of Aston, PA in the USA.

How long will it take to get my rubber door?

Once you order your door it will typically take 4-5 weeks to arrive.

How long does installing a rubber overhead door take and who will install it?

Depending on size, number of doors, and accessibility, install time normally takes 1-2 days. Our authorized dealers, located throughout the world, handle the majority of our installations.
