The Nautilus Shutter System

The unique, patented design of the Nautilus Rolling Shutter System provides many new features and benefits. Combined with increased strength and versatility, this shutter is in a class of its own. (US Patent Number 6,095,225 and 7,409,980).

The Nautilus is the world’s most compact rolling shutter system! No other aluminum rolling shutter can match the extraordinarily compact housing sizes. 72″ Unit height = 6.0″ housing. 144″ Unit height = 7.0″ housing.

Nautilus Span & Design Pressure Capacity

  • 96″ Span = 160psf Concrete, 160psf Filled Block
  • 144″ Span = 106psf Concrete, 95psf Filled Block
  • 192″ Span = 77psf Concrete, 63psf Filled Block
  • 240″ Span = 55psf Concrete, 45psf Filled Block


The phenomenal strength and design load capacity of the Nautilus system speaks for itself. Ideal for residential, storefront, commercial, mid-rise and even high-rise applications.

This Nautilus may be small in size, but it’s huge in strength! Tested for large missile impact. Approved for FBC NHVHZ, FL 12246 and FBC HVHZ, FL17079.

The Nautilus Rolling Shutter System undergoes extensive and rigorous testing including large missile impact tests, forced entry tests for security purposes and are fatigue tested for up to 15,000 cycles to ensure the integrity and durability of each and every component. The Nautilus is Florida Building Code approved for non high velocity hurricane zones (NHVNZ) and high velocity (Dade and Broward counties) hurricane zones (HVHZ). Nautilus rolling shutters outperform every roll shutter on the market.

*The weight of the curtain is neutralized with the use of a balance spring. The base slat contains a spring loaded keyed lock.

The Nautilus Rolling Shutter System is manufactured with only the highest quality aluminum components. The slats, axles, housings, and end caps are all fabricated from 6063 T-6 aluminum alloy.

The Nautilus curtain is fabricated from ten different size slats that get progressively larger ranging in size from 1.765″ for slat number one to 3.272″ for slat number ten. Each slat is used in groups of five. Five number one slats are slid together and create one 360 degree circle around the axle. Five number two slats are added to create another 360 degree circle around slat number one. Five number three slats are then added. Slats are added in groups of five until the desired curtain height is achieved.

The Nautilus Rolling Shutter System has a variety of uses including hurricane shutter protection for typically mounted and built-in applications, storefront, security, countertops and is ideal for large porches and balconies.

Interlocking Hinge

The Nautilus slat uses an interlocking hinge which eliminates all “play” between slats. This allows the balance spring to operate to 100% of its capacity, neutralizing the weight of the entire curtain. This enables the end user to operate a very large 120 sq. ft. shutter manually with a crank or by pulling the shutter up and down by hand. The use of the starter slat which is affixed directly to the axle, the #12 retention screw and interlocking hinge create a shutter which is virtually impossible to breach by way of forced entry.

Back To Top

Side Rail

The end retention side rail measures 4″ in width and 1 ¼” deep. The rail is designed with two grooves on the inside of each side of the track to receive felt strips. A single felt strip on each side is utilized for standard household applications and a double felt strip is installed for shutters that are used on a daily basis such as storefront and countertop applications. A decorative snap cover is used to conceal fastening hardware and deter access for security purposes. Rails are pre punched.

End Cap

The Nautilus is the only shutter in the industry that utilizes an extruded aluminum end cap. This adds substantial strength to the shutter and eliminates the problem of end cap failure; a common occurrence with cast end caps. The end cap goes through a five step pre-treatment process to prep the substrate prior to painting. The process includes a chemical bath, clean water rinse, acid etch, a second clean water rinse and a deionization treatment to eliminate any mineral residue. The end cap is then painted with marine grade super durable polyester powder coat paint. Using an extruded aluminum end cap eliminates the potential for out gassing; a common occurrence for cast end caps. Out gassing is the cause of paint failure resulting in cracking and peeling of the paint. Nothing gets through the bolted end cap; all components are attached from within the shutter. This allows for end to end and trapped installations to be serviced without removing the shutter.

Bayonet/End Cap Leg

The Nautilus bayonet is extruded aluminum and has been tested to 400lbs. eliminating the problem of the end cap leg snapping off during installation; unlike cast end cap legs. The extruded bayonet allows the installer to simply slide the side rails on each bayonet, lean the shutter forward and secure it, cutting down installation time.

Back To Top


The Nautilus utilizes 60mm and 70mm extruded aluminum axles. All axles are painted with an electro-statically applied baked on enamel paint. This helps eliminate the wear lines that typically appear on the upper slats.

Assembly Hardware

Only 316 or 410 series marine grade stainless steel hardware is used in the construction of the Nautilus Rolling Shutter. The end retention screw is a 2 ¾” #12- 410 stainless steel truss head. The screw is spray coated with AC-Silver, a two part corrosive resistant coating. A zinc-rich base coat provides sacrificial protection of the stainless steel substrate while the aluminum rich organic top coat creates a durable barrier which provides exceptional galvanic corrosion resistance. AC-Silver is salt spray tested for 1000 hours. The retention bushing is made of high performance acetel polymer.

Motorization & Electronics

The Nautilus Rolling Shutter System uses only Somfy and Simu motors and control systems. Somfy is the world’s leading manufacturer of roll shutter motors and control systems including hand held remote controls, override systems, built-in receivers, keyed and keypad entry systems. Somfy and simu products are ISO 9001 certified and posses safety approvals from Underwriters Laboratories. Somfy and Simu motors and control systems carry a 5 year warranty.

In order to better serve our customers, in the event a motor or component failure occurs, E.S.S. mfg. will immediately send out a new motor or component. The damaged part must be returned to E.S.S. mfg. and we will handle the warranty with Somfy and Simu.

E.S.S. mfg. has reduced the cost of all Somfy and Simu brand motors and control systems, allowing you to compete favorably with the less expensive, less reliable Chinese motors.

Nautilus Shutter Measuring Instructions

Width-use only finished width outside of track to outside of track

-Tracks measure 4″ so add minimum of 8″ for finished width

-Design pressures or substrate may require greater edge distance that would increase finished width. Check engineering details.

Back To Top

Hood-use finished height to top of hood

-Add any distance you want the shutter to extend below the opening to the opening height before calculating finished height. Add 1″ to the bottom for a sill angle. Opening height for doors should include the distance from the bottom of the opening to the floor or deck.

-Bottom slat hangs down 2 ¾” below the hood for hand and manual units. Electric unit limits can be set so bottom slat only extends 1″ to 2″ below hood.

Back To Top

Hood capacities

6″ hood-up to 72″ finished height

7″ hood-up to 144″ finished height

8″ hood-up to 168″ finished height

9″ hood-up to 192″ finished height

Back To Top

Addition to opening height-non motorized

6″ hood add 2 ¾” = opening height plus 8 ¾”

7″ hood add 2 ¾” = opening height plus 9 ¾”

8″ hood add 2 ¾” = opening height plus 10 ¾”

9″ hood add 2 ¾” = buck opening height plus 11 ¾”
