Man Door Access Doors

About Man Doors

Man doors are doors within doors. For instance, you can have a large sliding door, say 14 ft tall and 20 ft wide. You might not want to slide that big door back and forth every time you access the space. No problem. Just install a separate egress point (a man door) inside that large oversized door and you have simple method or entering and exiting the space without having to articulate the mother door.

Man doors can be tricky because the host door (which can be very large, potentially up to 40 ft or more) must be built with very high structural integrity so as to accommodate the regular and potentially heavy use of the man door.

That’s why the world’s best large doors with man doors are made with Sing Core, because using Sing Core is the only way to build such a door which can be guaranteed not to warp, bend, twist, or otherwise fail, and you need this high precision dimensional stability to accomplish such a feat, over time.

That’s why inventor Peter Sing guarantees his warp-free large door solution to remain warp-free for 50 years. No other lightweight, fully insulated, sound deadening and climate control large door in the world can make such a claim. Not only is Sing Core the best way to do it, it is the only way to do  it.

Metal-Sliding Hot Rolled Steel Metal Door-Man Door

A Man Door is a man-sized access door that is pre-built ~ or after market modified ~ in a larger door to provide access of an individual without having to open the entire large door, exposing the entire area.  Man Doors are also referred to as pedestrian doors, pass doors and/or access doors.  Man doors are one of the absolute best ways possible to add additional functionality and character to your high end residential and commercial locations.  What’s more, you can order your man door in any skin, even metal skins, like hot rolled and cold rolled steel, aluminum, bronze, brass, and copper.

Sing Core makes the best man doors. Why? Because our Eco-friendly high-precision lightweight and high strength core material allows door manufacturers to create doors of enormous size while keeping them straight and true. So perfectly straight and true, in fact, that Sing Core offers a free large door consultation that can result in a professional large door that can be guaranteed true flat and to remain true flat for 50 years.

When you have a super large door (could be as big as a hangar door) in many cases you don’t want to open the entire door area just to access the space. That’s where the Sing Man Door comes in. There’s no doubt that Sing Core is the go to source for insulated large doors of any size that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years.

It is quite common for someone who seeks out the services of Sing Core to request that a large oversize door come with an access door that allows egress without having to unsecure the entire big door area. In most cases Sing Man Doors are simply Sing Metal Doors incorporated into the design of the original oversized door.

Very few companies can compete with Sing Core when it comes to man doors, because of the extremely high precision, strength, and lightweight characteristics required in making a man door suitable for use for decades to come.  Our Professional Man Doors come with our 50 Year Warp Free Guarantee and are 100% made in USA using materials sourced from USA.  We pride ourselves on making the best man doors in the business.

Large doors with articulating access panels are common, and are increasing in popularity amongst garage door companies who use Sing Core as their substrate material for their large garage doors.

Man Doors can be includes in all types of doors, including (but not limited to) large sliding doors, overhead doors, large pivot doors, large swing doors, large carriage doors, and more…

Maybe it’s time you thought about having pedestrian access via a specially designed pedestrian door to be used as a pass door allowing access to your space in a smart, more economical and secure fashion.

Millworks

Looking for a millwork to finish your SingCore project?

patented Sing sliding non warp large doorOur primary affiliation is with the millworks that are highly skilled and qualified to deliver an end product which exemplifies the highest and best use of our patented SingCore building materials. In fact, when we receive inquiries about our products, our first question is, “Who is your millwork company?” If they do not have one they are working with, we suggest they get one and have them contact us directly.

SingCore is an extraordinary building material that left to itself is not much more glamorous than any other engineered plywood, even though nothing can compare to SingCore’s unparalleled light weight and strength. Yet, in the hands of a skilled millwork, their specialized craftsmanship is what makes Eco-friendly SingCore shine with the beauty and elegance SingCore products are known for.

Millworks face many challenges when bringing the architect’s vision to life. In some cases, the limitation of available building material can render a potential job impractical or even impossible.

Problem

Large non warp exterior sliding doors guaranteed for 50 years lightweight high strengthFor instance, a particular project might include a large wooden door. If the large wood door is an exterior door over seven feet tall or over four feet wide (as is the case for most modern pivot entry doors) millworks and custom door manufacturers will simply pass on the large door portion of the job, forfeit the entire job altogether based on the oversized exterior door, or if they do take the job may agree to build the large door according to the architectural specifications but will not offer a warranty on the performance of the big door.

Large exterior doors, especially large wood doors, are a problem because millworks and door manufacturers know the doors will fail due to warping. It’s nothing personal; it’s just the nature of the beast being the wood grain itself which tends to move according to changes in temperature, moisture or other environmental conditions.

Solution

Building warp-free wood doors of any size with SingCorePatented SingCore when engineered by the warp-free team can prevent any large door from failing over time. Millworks are confident they can provide a solution for any project including large doors of any size if they have SingCore inside, guaranteed.

Clients may ask for a warranty on the large doors (that without SingCore inside could not be warranted) and the millwork can now offer the professional SingCore guarantee – in writing – that the doors with professional SingCore inside are guaranteed not to warp, bend, twist or otherwise fail for 50 years.

Working with SingCore

millwork-cnc-router-sing-panel-sing-core-lightweight-high-strength-50-year-warp-free-guarantee

Easy to CNC router

Millworks use either open edge or closed edge Sing Panel, whichever works best for the project at hand, as well as many options for skin types, solid blocking, custom lite cut outs, solid and exterior edging options.

SingCore is easy to machine and work with using traditional woodworking tools, CNC and edge –banding machinery and equipment.

Used as substrate material, SingCore can be delivered to the millwork ready for cold press or hot press lamination. Alternatively, millworks may desire exterior surfaces to be applied in our factory, which makes their job easier.

Sing Insulated Aluminum Panels

Sing Insulated Aluminum Panels are an Eco-friendly unique combination of traditional high-end carpentry skills and modern space-age technology alternative to other insulated aluminum panels that are lightweight and high strength and proudly made in the USA.

insulated aluminum panels eco friendly lightweight high strength demonstration

Strength deflection demonstration of 1 inch 13 ft. long insulated aluminum panel

What makes Sing Insulated Aluminum Panels different from other insulated aluminum panels?

The beginning of the Sing Insulated Aluminum Panel’s uniqueness, you must start at the heart of the insulated aluminum panel, which is the SingCore. The patented core features a structure grid built of vertical grain torsion box. For many years, torsion box has been known to add strength and stability to large structures covering long spans while reducing the overall weight.

Left to itself, the torsion box structure is traditionally left empty. Instead of being left empty the empty spaces inside the torsion box structure grids are filled with rigid foam insulation, which gives the Sing Insulated Aluminum panels their insulation R value and unparalleled shear strength. The substructure is then sandwiched between two aluminum stress skins and laminated with formaldehyde-free glue, to form an insulated aluminum panel which is stronger than steel (660 PSI) pound for pound.

High Precision Insulated Aluminum Panels

insulated aluminum panels lightweight demonstration styrofoam insulation r value

Lightweight insulated aluminum panel

No other insulated aluminum panel is so high precision while other core materials vary in thickness across the span of the panel SingCore exemplifies new standards of precision with extremely accurate tolerance of +/- .006 inch.

This extreme high precision is why Sing Insulated Aluminum Panels are used in high-end industrial applications throughout the United States government and science industries including the military, aerospace and NASA.

Aluminum Raised Floor, Shelving

You can use Sing aluminum panels as shelves or raised flooring throughout your private or commercial vehicles for better handling cargo. The lightweight and high strength offers organization and clarity, without compromising vehicle weight or handling, so you can add any configuration or levels which would best suit your needs.

Photos (above) show Sing aluminum panels installed in a van being used as a raised floor, shelf, or truck bed.

Custom Insulated Aluminum Panels

Insulation R value starts at R3.5 per inch and can be increased to meet your architectural specification by filling the torsion box voids with other varieties of rigid insulation materials possessing higher insulation values and/or fully encapsulated insulation and substrate.

In fact, all Sing Insulated Aluminum Panels are custom manufactured in our factory located in the scenic Pacific Northwest to architectural specifications. It’s as if each insulated aluminum panel is an individual work of art. Specifications may include any variety of materials to meet specific high performance standards.

Other Applications

Not restricted for only use as industrial insulation panels, Sing Insulated Aluminum Panels are found in commercial applications, such as retail, office, refrigeration and hospitality industries and in high end real estate and homes as insulated aluminum doors.

Insulated Aluminum Doors

Sing Insulated Aluminum Panels are probably the best material to use for creating insulated aluminum doors, especially if the door in question is a large, oversized door. The lightweight, impressive shear strength and insulation reinforcement makes large doors foolproof with accuracy higher than solid steel at a fraction of the weight, reducing the cost of any large high-end metal door project immensely.

Cut Down on Expenses

The weight of the metal door dictates hardware and supporting structure requirements, which are expensive considerations for heavy doors. Heavy doors are also more expensive to transport and install requiring heavy equipment and labor, while insulated aluminum doors made with Sing Insulated Aluminum Panels are lightweight, less expensive to ship, handle and install. Plus the structural insulated panels cost savings of having an insulated end product as well as doors that require less maintenance over time.

50 Year No Fail Guarantee

Only Sing Insulated Aluminum Panels can be guaranteed not to warp, bend, twist or otherwise fail (including full structure guarantee) for 50 years. That’s an impressive 50 year guarantee that is not something seen in industrial, commercial or residential industries. This 50 year guarantee would not be possible if not for the unprecedented structure strength of SingCore inside each Sing Insulated Aluminum Panel.

If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.
