Features and Benefits
Tensile Membrane Structure
True tensile membrane structure
Like a well-trimmed sail, En-Fold’s patented drive mechanism applies precise biaxial pretension to the fabric membrane, thus transforming it into a lightweight tensile structure.

En-Fold comes standard with Sefar Tenara 4T40, the industry’s most translucent, long lasting and pliable fabric membrane material.
Attributes include: Strength (high strength-to-weight ratio), Chemical inertness Biocompatibility, High thermal resistance, High chemical resistance in harsh environments, Low flammability, Low coefficient of friction, Low dielectric constant, Low water adsorption, Good weathering properties.
For applications where cost, or color options are a primary criteria En-Fold is also available with other water proof, pliable fabric membrane materials such as Serge Ferrari 502, 702, 1002 S2 and 1202 S2.
Additional fabric options are possible as Uni-Systems’ engineers are always researching and testing the applicability of new fabric membranes.

Picking up where other commercially available retractable awnings reach their limits, En-Fold is perfectly suited for medium to very large applications.
En-Fold’s high performance extruded aluminum drive beams are capable of spans from 20 feet to 40 feet without added support.
With supplemental support, En-Fold’s drive beams are capable of spans up to 100 feet. Due to En-fold’s unique modular construction widths in excess of 200 feet in a single unit are possible.

Weather Protection Sun/Rain/Wind
Redefining the line between indoors and out; En-Fold retractable fabric roof maintains the open sky when weather permits or a protective cover in the case of inclement weather.
Wind mitigation plays an important role in the creation of appealing indoor/outdoor spaces and surprisingly the simple addition of an En-Fold roof can greatly reduce wind in many instances by creating a pressure pocket in the semienclosed space, thus causing the wind to go up and over the structure.
Excessive sunshine will almost always prevent customers from sitting outdoors, unless shade can be provided. Depending on fabric selection, En-Fold allows from 5% to 40% light transmission and effectively blocks 100% of the sun’s harmful UV rays.
Even the remote threat of rain can prevent customers from booking reservations for an outdoor table and the water tight En-Fold can guarantee that customers will stay dry even in the worst of rainstorms.
En-Fold is made up of a small number of identical sub-assemblies that join in an unlimited number of configurations.
The primary sub-assemblies are the patented drive beams that house all of the mechanization and support the entire system, the individual fabric membrane panels and the idler beams that run perpendicular to the drive beams and support fabric.
En-Fold’s fabric membrane panels are divided up into long narrow strips that slide into the keder edge retaining features integral to the lightweight extruded aluminum idler beams.

With any retractable system, the desired effect is minimal structure overhead, to provide the most open feel and clearest view of the sky.
En-Fold’s unique design allows for wide drive beam spacing which means that when the membrane is retracted very little structure remains to block the view.
All exposed materials are corrosion resistant.
Anodized aluminum structural members.
Stainless steel cables and fittings.
The standard fabric membrane is composed of 100% ePTFE (expanded polytetraflouroethelene) a thin, lightweight waterproof, windproof chemically inert material with excellent weathering properties.
Control Systems Options
Control System Options
Standard control package includes one cabinet mounted operator control station (OCS) and one handheld remote control.
Tie-in to building management system.
Tie-in to fire/smoke detection systems.
Tie-in to anemometer.

When fully tensioned, the interface between the individual fabric panels and the aluminum idler beams creates a watertight seal.
Watertight seals are available for all En-Fold-to-building interfaces.
Integral gutters are also available for En-Fold-to-building interfaces.
Adaptable to Surrounding Architecture
Adaptable to Surrounding Architecture
En-Fold is highly adaptable due to its modular construction and infinite configuration options.
Can be customized to suit the design criteria of the owner or architect.

En-Fold’s extruded aluminum structural members are available in standard clear anodized finish, or a number of premium finishes.
These finishes include a limited number of anodized colors, or an infinite number of Sherwin Williams Acrolon acrylic polyurethane paint colors.

Easy to Purchase
Easy to Purchase
En-Fold is a customizable architectural product that can easily be purchased off a P.O., just like any other piece of capital equipment.

Off-the-shelf components means rapid assembly and the modular construction results in very short installation times given the square footage the product is able to cover.
Return on Investment
ROI is an important calculation for any large capital expense.
Outdoor seating can increase the number of customers served during dinner service hours, but only when the weather cooperates. Studies conducted in the sports industry on the cost benefit of retractable roofs concluded that at $1m revenue per game a rain-out can cost a ball club as much as $7m per year, but the losses don’t stop there. Even the threat of rain over an 80 game season can cost a ball club an additional $2.5m per year and rain delays can net an additional $600k in losses. All tallied this can mean losses of over $10m annually.
While restaurants and bars don’t see revenue of $1m per night the weather will influence customer behavior in a similar manner and will have a negative impact on RevPASH.
En-Fold is a lightweight structure that covers large spaces with minimal amount of material.
The standard Tenara fabric membrane material has a 25+ year life expectancy and is 100% recyclable.
The all-aluminum structural members are also 100% recyclable.
Blurring the lines between indoors and out, En-Fold allows for natural ventilation and day lighting, to reduce the load on HVAC and electrical systems.
En-Fold is also an excellent source of shade and can help to reduce thermal gain in adjoining structures.
