Aluminum Bifold Doors in NJ & NYC

Bi-Folding Doors

Komar Stroy supplies and installs aluminium bi-folding door systems across New Jersey, New York City, Connecticut, Pennsylvania and Massachusetts, with supply nationwide. Bi-folds concertina back on a track so the panels stack to one or both sides, opening almost the entire structural aperture. Where a sliding door always leaves at least one panel across the opening, a bi-fold clears it.

We install bi-fold doors throughout New Jersey, from Bergen and Hudson counties in the north to South Jersey communities in Camden and Gloucester counties, as well as in New York City, Connecticut, Pennsylvania and Massachusetts.

When a Bi-Fold Is the Right Choice

Bi-folds suit projects where the wall between inside and outside should effectively disappear: rear extensions onto a garden, roof terraces, restaurant and bar frontages that open to the street in summer, and hospitality spaces that need to reconfigure.

The trade-off is the stack. Folded panels occupy depth at the jamb, so the reveal and any adjacent furniture or structure need to accommodate them. We confirm stack depth against the architectural detail before ordering.

Configurations

Systems run from two to seven leaves, folding all to one side or split between both jambs. A traffic door can be incorporated so one leaf operates as a conventional swing door for everyday access without folding the whole set back.

Tracks can be top-hung or bottom-rolling. Top-hung carries the panel weight in the head, which keeps the threshold cleaner and reduces debris problems in the track; it requires adequate structural support above the opening, which we coordinate with the structural engineer.

Thresholds and Weather Performance

Thresholds can be specified flush for a genuinely level transition between interior floor and terrace, or with a weathered upstand where exposure demands it. Flush thresholds look better and meet barrier-free requirements, but need proper drainage design beneath, which we detail rather than leave to the general contractor.

Panels are thermally broken and glazed double or triple with low-E coatings, warm-edge spacers, and argon fill. Because the glazed area is large and the panels are operable, gasket quality and hardware adjustment matter as much as the glass specification.

What We Handle

Field measurement, structural coordination for the head condition, shop drawings, factory ordering, delivery, and installation by our own crews. Bi-folds require an accurately level and plumb opening to run smoothly over their life, so we survey and correct before the frame is set, and we adjust the hardware at handover.

Bifold Doors in South Jersey

We supply and install aluminum bifold doors in South Jersey, in Camden County and Gloucester County, including Haddonfield, Collingswood, West Deptford, Swedesboro, Mickleton, Clarksboro, Wenonah, Pitman and Washington Township. Each project gets the same scope as our North Jersey and New York work: field measurement, shop drawings, factory ordering, delivery and installation by our own crews.

Bifold doors suit rear extensions opening onto a garden or terrace, kitchen and family-room walls that open fully to the outside, and restaurant or bar frontages that open to the street in summer.

Bifold Doors in North Jersey and NYC

From our Teterboro facility we also install bifold doors across Bergen and Hudson counties and the rest of New Jersey, in all five New York City boroughs, Long Island and Westchester, and in Connecticut, Pennsylvania and Massachusetts.

Bifold Door Performance

Our aluminum bi-folding doors run from two to seven panels, with US U-factors of 0.23–0.30, sound insulation up to STC 48, glass up to 2 15/32 in thick and forced entry resistance tested to ASTM F588 Grade 10. For the most demanding projects we also supply Schüco door systems as an authorized Schüco partner.

Frequently Asked Questions

How many panels can a bifold door have?

Our aluminum bifold systems run from two to seven panels, folding all to one side or split between both jambs. A traffic door can be included so one panel works as an everyday swing door.

Should I choose a bifold or a sliding door?

A bifold clears almost the entire opening because the panels stack to the side. A sliding or lift-and-slide door always leaves at least one panel across the opening, but gives slimmer sightlines and no stack at the jamb.

Do you install bifold doors in South Jersey?

Yes. We install bifold doors across Camden and Gloucester counties, including Haddonfield, Collingswood, West Deptford, Swedesboro, Mickleton, Clarksboro, Wenonah, Pitman and Washington Township, as well as throughout North Jersey and New York City.

How energy efficient are aluminum bifold doors?

Our bifold panels are thermally broken and glazed double or triple with low-E coatings, warm-edge spacers and argon fill, with US U-factors of 0.23–0.30.

How long does a bifold door take to order?

Bifold doors are made to order. Typical lead time is about 2.5 months including production and shipping.
