Great question, especially since we are using the same OEM hardware as the leading brands. There is of course a longer answer to this question, but it really comes down to simplicity. A folding door system has three major components; the frame, panels, and hardware. We do no mass produce any of these components (a.k.a, large investments) which means our products are made to order. This significantly reduces overhead cost and the savings are passed on to our customers.

Yes. We can completely customize a hardware kit to include all components necessary for your particular configuration and need.

Fiberglass doors are manufactured from Plastpro® using a compression mold process. The expense associated with tooling the molds is quite substantial, making popular standard sizes the only reasonable option.

Because out-swing always outperforms against the exterior elements. When it comes to folding doors, out-swing is the industry standard unless something else prevents it, such as a certain commercial building code or a structural anomaly.

We can give you resources to help guide the installation but that is really a question only you can answer. Some questions worth considering would be, do you have door installation experience of any kind? Do you feel confident with your ability to prepare the rough opening of your structure for weather tight performance using appropriate flashing, caulking, sill pan, etc? Do you have someone willing to assist with lifting the door frame into place of your rough opening? Are you confident that the header material of your opening is structurally sound to support a top hanging door system? Because there is a degree of complexity from planning and installation, most people opt for a professional installation through a contractor or dealer. 

This is really a question for your engineer to determine based on weight and width of the door. However, we strongly suggest constructing an engineered beam, preferably with steel support.

Both vertical and horizontal adjustments are possible with all of our systems for fine tuning an installation and to correct any minor settling issues. This is a critical feature that not all bi-fold doors & window systems include.

There is no way to guarantee a ship date but we can certainly give you some averages.

Standard stock items such as smooth fiberglass (Nova 90) and stock timber doors: 4-6 weeks

Special order or custom doors: 7-9 weeks

Delivery dates are subject to change due to (but not limited to) production volume, supplier delays, or transportation delays.

Centor® Integrated Systems are manufactured at their headquarters and lead times vary according to their own variables. Most orders are produced within 12-13 weeks.



Integrated Doors & Windows by Centor® are unique in that they have integrated screen and shade systems directly into the units and in turn can be recessed easily into the structure of a rough opening, making a true “integration” with your home’s architectural design. Additionally, all hardware (hinges, rollers, locks, etc) is either minimally exposed or not exposed at all for a true seamless operation, without compromises.

At this time we only limit sales of Integrated Doors & Windows to Houston & Austin Texas to best serve our customers.

While we do allow direct customers purchasing our own line of doors to handle their installation by whatever means works best for them, Integrated Doors & Windows are a slightly different “breed”. Centor requires Dealers to use only their certified installers to manage the process.

Both vertical and horizontal adjustments are possible for fine tuning an installation and to correct any minor settling issues.


Novare folding doors, swing doors, and Genius® Retractable screens ship to the contiguous United States.

Centor® Integrated Systems, S4 and S2 screen & shade systems are limited to Houston & Austin Texas regions only.

Our systems are packaged as knock-down kits to be fully assembled on site. We crate them with plywood, fasteners, and crating straps for extra security. A fork-lift or a large team would need to be available to unload upon delivery. Most shipments are LTL.

We work with various carrier brokers to provide the best shipping options available. We collect your zip code during the estimate process to project a close calculation. If we determine later that we have over-estimated shipping costs, we refund that amount on the final invoice.
