DynaDome Enclosure Design & Construction

The Same (Standard), but Different (Custom)

Frame Spacing – As standard, all of our retractable enclosure systems are made of a series of rigid frames with 6’-1” centers that are inserted into two parallel tracks. The tracks or fixed frames are mounted/fastened to the structural supports. The frame centers can be customized to any dimension, but the standard is 6’-1”.

Inside Space / Heights – As a structure starting at ground or floor level, the standard inside minimum wall height is 7 feet. For rooftop applications, the vertical wall height is minimized to be as small as possible. For spaces requiring additional height, we can and will increase the height of the enclosure as long as our engineering department says the heights are ok.

Roof Pitch – The standard roof pitch of the enclosures is 3:12, but can be customized to any pitch. A custom pitch must be approved by a designer to make sure the proper drainage is considered as well constructability. There are other factors that may need to be considered when customizing the roof pitch, and these can be discussed with your design team.

Operation – Our standard is to have the enclosure move manually by pushing along the tracks. However, there are certain factors that will dictate the use of a motor – large span, rooftop application, commercial application, etc. If the operation of the enclosure is done by motor, then the opening and closing is all accomplished with the push of a button.

Retracted Length – As standard, our enclosures retract down to one-half (1/2) of its overall extended length. However, since we design all of our enclosures for each specific application, the retracted length could be as small as a single 6’ frame. The tradeoff with that would be a large amount of deck space taken up from the frames getting more and more narrow as it telescopes into itself.

Common Components – Although our proprietary shapes and certain standards are maintained so that many of our components are the same within each system, every enclosure we design is custom and different.


Structural Engineering & Design Loads

All of our enclosure systems are designed to meet the applicable building code requirements for your area. What that means is an engineer who is trained and licensed for your state will prepare engineering plans and calculations for your specific project. There are no rubber stamps. EVERY PROJECT IS UNIQUE!

The snow, wind, seismic, hurricane and any other structural loads dictated by your jurisdiction will be considered as we design the frame system that will be strong enough for your project. For our architects and other design friends, our DynaDome enclosures are designed to meet IBC design loading requirements for the project area. Every DynaDome system is designed for your local requirements by our engineers. You will receive stamped engineering plans that verify the structural adequacy of your DynaDome system. If your engineers require reactions at the base or service level loads so they can design the foundation or wall supports, we will provide that as well.


Materials & Construction Hardware

WITH DYNADOME, NO HVAC EQUIPMENT NECESSARY – What makes us different than general frame construction with a combination of wood, steel and drywall? In general frame construction, if the structure itself must be protected from the moisture. How do you that? With expensive HVAC equipment such as dehumidifiers, heaters, cooling systems as well as BACKUP SYSTEMS! These are all a requirement to prevent the moisture from damaging and eventually collapsing the building. As mentioned before, this equipment is a requirement and should be considered when pricing the buildings – that equipment is not cheap nor is the utility bill that keeps coming month after month to operate that equipment!

You don’t need any of those precautions or expenses in our DynaDome systems. The materials we use are primarily aluminum, plastics or glass, rubber and stainless steel. This combination of materials does not require any protection or treatment to keep the structure safe. The only reason you will add any heating or air movement equipment will be for comfort reasons. Otherwise, the materials are all safe to use in a harsh pool environment.

AIRCRAFT QUALITY ALUMINUM? – That’s right! We only use aircraft quality extruded aluminum alloys (6061-T6 or equivalent). If it is safe for use in airplanes, then you can be sure that it is safe to cover your space! What that means is any of the aluminum within the system that is meant to be structural is made of the same aluminum alloy as airplanes.

The framing connections are reinforced with a box-type heavy duty steel section that is coated to protect the steel from corrosion. This connection that keeps the frame rigid, strong and able to carry the strength

ANODIZED ALUMINUM, NOT PAINT – The protected finish on the aluminum is not a paint or other finish that will eventually peel and crack over time. Instead, we use an anodized finish that will be guaranteed for 20 years.

Why did we choose anodizing as a finish? We started in the retractable aluminum enclosure business in 1985. Over the years we have tested and used many different types of finish. The powder coating or painted finish always was a problem because of the constant temperature changes from summer to winter. What happens is the aluminum will expand and contract (gets bigger and smaller) due to the temperature changes. Well, the paint on the aluminum does not always expand and contract at the same rate. So, eventually what happened was the paint separated from the aluminum and began to peel and crack. You cannot use touchup paint or any other method to fix the peeling. That’s why we use anodizing because it is part of the aluminum – not a separate added on finish.

Anodizing will not peel or crack or otherwise separate from the aluminum. It is part of the aluminum and through a process gets enhanced to create the protected surface to prevent harmful chemicals or salt spray from damaging the aluminum itself. The anodizing process allows for the choice of colors depending on your application. Our standard color is the clear color which is called Satin (Silver). You have the option to upgrade to the rich, dark brown color (Dark Bronze) or black is also an option.

GLAZING (POLYCARBONATE AND GLASS) – In all of our enclosure systems, one of the main elements that draws customers to our products is the translucence, or in other words FREE LIGHTING! The polycarbonate we use in the roof is the thickest in the industry at 5/8” (16mm). The 16mm polycarbonate is primarily used in the roof and is very strong, lightweight material. It comes in 3-wall, 4-wall and even 5-wall construction. Although the 16mm polycarbonate is our standard, we can also use 25mm, or a combination of multi-layered 16mm panels sandwiched to an overall depth necessary for meeting energy requirements. The standard color provide is clear, but tinted bronze and opaque colors are also available as upgrades. The vertical walls are all glazed with solid transparent panels for a glass room look.

Glass panels are also available for varying levels of need including soundproofing, shading/lighting, energy efficiencies, etc. Note that there is a cost associated with the glass as compared with the polycarbonate panels.

FASTENERS – All of our screws and other fasteners are only made of stainless steel which will not rust or otherwise become corroded in a harsh environment such as a swimming pool area with chemicals and moisture in the air.

SEALS – All of the glazing is sealed with EPDM gaskets which are designed to keep the water out. If the water does make it passed the gaskets there are weep channels and guides that will redirect any water back out to keep you and your space dry within the system. The frames that overlap each other are sealed with a wall and compressible seal system to keep wind, dirt, debris and the weather outside so you can enjoy the inside. Where the system attaches or mounts to your supporting system, the buyer is required to develop a drainage or sealing system, including at the base for freestanding systems and at the wall for lean-to type systems.


DynaDome Enclosure Sizes

DynaDome Can Go the Distance!

Residential Applications

The minimum length per frame is 6 feet and increases in 4′ or 6′ increments to any length. The overall length of the entire system can be as long as you want it or need it to be.

The maximum span for residential applications is 60 feet wide. The components may vary depending on the structural loading for your area. For instance, if you live in Tampa, Florida you may not need heavy beams to hold the snow in the roof, but you may need them for the winds you get during hurricane season!

The inside height of the enclosures start at a minimum of 7 feet and can be a maximum of 10 feet.


Commercial Applications

The minimum length per frame is 12 feet and increases in 4′ or 6′ increments to any length. As is the case with our residential enclosure systems, the overall length of the entire system can be as long as you want it or need it to be.

The maximum span for commercial applications is 120’ feet. Yes, 120 feet fully retractable enclosure system by DynaDome! With the larger spans for our friends at YMCAs, JCCs, municipal pools and military installations, the shape of the enclosure is defined for you with either a 7-point or 9-point frame system.
