Phoenix Domes 2-Pack Opening Triangle Glass Windows

Upgrade your Dome with 2 opening, double pane glass windows for clearer views and optimal airflow!

Featuring a hydraulic arm to ensure your window stays open to the desired level, as well as a standard locking latch. Custom velcro mosquito screens are available where desired.

Includes mounting & finishing brackets for 6m or  7m to install in the center of the triangle, or install it in the bottom of the triangle for any size Dome

* Please note: due to the size, the website is unable to calculate freight accurately, so additional shipping charges may apply - if in doubt, best to contact us for a quote

Our triangle windows are all one size, which means they most likely will not fully cover an existing window opening on your Dome unless it is one of our smaller sizes. We recommend installing your triangle window in a new location of your Dome for the easiest installation, which is what the attachment struts are designed for (this will centre your window in the opening). If you are planning to install your glass window in an existing vent, you may want to install it low in the triangle and glue the top of the flap down for ease of access and weatherproofing. please consult our instructions for more information. 

 * Back in stock but currently only available in 2-packs unless ordered with a custom dome and packed at the factory - we don't currently have a way to separate the 2-packs and repack them safely for shipping individually * 

 

This Kit Includes:

  • Opening triangle window with hydraulic arm
  • Thick triangle mounting bracket
  • 3 x attachment bars specific to the size of your Dome
  • Thin metal finishing strips
  • Packet of self-tapping metal screws
  • Tube of Weathermaster sealant for waterproofing

 

Outer Perimeter - 43x42x43”

Inner Perimeter - 35x34x35”

Window Placement:

Our triangle windows are isosceles (2 sides of equal length) and are optimized for downward-facing 3-2-3 triangles in 3V Domes, as per the 3V Dome layout diagram included above with the photo set. If you plan to install a loft, this can be a consideration for window placement. Our glass windows are also well-suited for 4V Domes, however they may require the fabrication of custom bracket struts in order to compensate for the larger triangles involved.

You have the option of replacing an existing triangle window with a glass one, or simply cutting through your Dome cover/bubble liner insulation layer to create a window in a new location. For a clean finish when used with our Oxford fabric liner (or similar), our window kits do include strips of stainless steel trim that can be painted to your desired shade and secured to the interior triangle bracket (also included) with your Oxford liner tucked underneath.

Specifying Window Location in Advance:

If you are ordering a Custom Dome, it can add to your aesthetic and save you time during installation to specify your glass window's location prior to your Dome's manufacture.

If you will be placing it overtop an existing triangle window, this ensures you will not have to remove the velcro window flap strips during installation (it will simply be manufactured with one triangle window left open, and most likely be cut slightly smaller than a standard velcro vent would otherwise be). Removing the velcro will be unavoidable, but not massively problematic, if you plan to install your glass window overtop an existing window on a 4-Season Glamping Package Dome or one that you've already had for however long. 

Depending on the size of your Dome or the existing triangle vent, the glass window may be smaller than the vent. In that case, you can glue down the flap at the top of your vent such that it reaches the window, or request additional cover vinyl from us as necessary. The glass window includes a heavy duty vinyl sealant for this purpose. 

If you intend to create an additional window in a new location, it this is easily done by cutting the cover to the size of the window at installation. 

Please get in touch with us via prior to purchase in order to ensure the correct size window for your Dome and its placement.

PLANNING AND BUILDING

What size Dome do I need?

  • 16’/5m – 210 sqft - suitable for short-term guest accommodation for a single or couple with little room for more, if outside facilities are existing for bathroom, kitchen, etc. Also a nice size for an art studio or massage space
  • 20’/6m – 300 sqft. - suitable for a couple with room to lounge/stretch out and a sink/kitchenette if outside bathroom facilities exist. A small bathroom cell can be added for short-term guest accommodation. Also a great size for a studio or yoga/ movement space.
  • 23’/7m – 400 sqft – suitable for a couple or family of 4 with a full bathroom, king size bed, loft bed or pullout couch, and plenty of room to lounge. Our most popular and versatile glamping size. A loft bed above the bathroom/kitchenette is possible.
  • 26’/8m – 540 sqft. – Luxury accommodation that can fit larger families. The height makes a loft area attractive, which can be above the bathroom/kitchen. A separate bedroom is also a possibility.
  • 30’/9m – 700 sqft – This size is great for a yoga studio, outdoor classroom, workshop space, or a long term residence for 2.
  • 33’/10m – 850 sqft – Yoga studio, circus arts, events, dance and workshop, a restaurant dining area, or full time residence for a small family – possibilities are endless!
What kind of floor will I put my Dome on?

Most of our customers choose to build wooden platforms – they can be elevated off the ground, erected on uneven or sloped terrain, are low-impact on the environment and ultimately removable. For year round use, we recommend insulating the platform.

We provide engineered platform plans for our common dome sizes with detailed cuts, measurements, and angles that you can use to build it yourself or give to a local contractor.

Other options for flooring are poured concrete slabs (potentially insulated with radiant heat), or earthen/ cob floors. For a temporary setup, we can provide heavy duty waterproof ground tarps that can be spread directly on the ground.

We have also built a sprung dancefloor in a dome with a plywood floor over recycled tires!

How do I attach the Dome to the platform?

The dome frame has feet that can bolt into the platform - or into a concrete pad if needed. If setting up directly on the ground, you can also use ground screws or rebar to attach the feet. 

Then, the outer cover ideally extends past the edge of the platform if it is a close fit (use our Platform Plans that fit our domes exactly!), and can be fastened with staples or trim to keep weather and critters out. 

This type of trim works well and looks neat.  

Please note that we recommend building the platform to our plans to fit the dome exactly – that way it is easy to seal the cover skirt around the edges with some trim to keep weather and critters out. An outside deck can be built off the side of it. If you want to put your dome on a larger, rectangular deck, you need to account for a drainage gap around the dome perimeter to ensure rainwater cannot run under the edge of the dome. Usually in this case, you will want to build up an insulated floor on the inside.

How do I heat my Dome?

A dome can be heated in all the ways a house can be heated.

For off-grid applications, a wood stove is best. However, if you are doing a commercial glamping rental, you may not want to teach all of your guests from the city how to safely and efficiently operate a wood stove. In this case, Pellet stoves, externally vented propane stoves, radiant infloor heat, electric heat or a combination thereof are all good options.

Please make sure to upsize your heat source as a dome does not have the same insulation as a house. If the dome is 400 sqft, use a stove that is good for 800-1000.

We supply chimney and vent flashing kits to fit any size – they can be installed wherever you need on the dome without a pre-determined hole. Just let us know what size you need!

How is a Dome insulated?

Our insulation liner consists of 2 separate layers – a double reflective bubble wrap layer that is pulled over top of the frame, and underneath the outer cover – and an inner fabric liner that creates an additional air pocket to help with insulation. The way the reflective layer works is that it will reflect heat back into the space, aided by the spherical, very energy efficient shape of the dome. This will result in about an R5 overall. However, it will not hold heat for very long after the heat source is out – for this you would need several inches of insulation material.

Many of our customers operate year round with our insulation package and good stoves.

For a permanent structure, you can get the inside of your dome sprayfoamed by a local company to achieve a much higher R-Value more similar to a cabin or house while also eliminating any thermal bridging or condensation on the frame – but it means that the dome cannot be taken down easily anymore. The sprayfoam can then still be covered with the inner fabric liner.

What does it take to set up a Dome?

A dome can usually be set up in 1-3 days with a team of 3 people. You will need extra help, a winch or a truck to pull the heavy cover over. Domes up to 23’ can be set up with a couple of ladders alone, larger ones will require some scaffolding. Other than that, some wrenches, ideally an impact driver with a couple of long sockets (17mm and 19mm), a rope to pull the cover and some ratchet straps to get the tensioning hooks on are all you need.

You can download our installation instructions here.

Do you sell washrooms, kitchens, heating and cooling appliances?

No – due to the myriad ways a dome can be used, styled and outfitted, we decided to leave the creativity up to the customer instead of trying to fit prefab units – you will be able to get much better quality and unique design by sourcing furniture, appliances and fixtures locally or online, hiring local contractors and going with your own style.

How strong are Domes?

Geodesic domes are the strongest structure invented by man (in relation to the materials used) – just like nature invented the egg, Canadian visionary and architect Buckminster Fuller invented the geodesic dome structure consisting of triangles that disperse loads across the entire structure. 

We have a few different frame sizes that have been engineered for various snow and wind loads (40-100 psf and up to 300 kmh winds) so you can rest assured that your dome with withstand any weather conditions you may encounter.

We are also able to provide engineer reports (currently for NS, NB, ON and BC) for our most common sizes in order to assist our customers with obtaining building permits.

We had multiple customers report that Hurricane Fiona was no match for their Phoenix Domes! Read more about it on our Testimonials page.

Do I need a building permit for my Dome?

It depends. Our domes are technically tents, thus temporary structures that can be dismantled in a day.

Many of our customers living rurally decide to avoid the bureaucratic hassle and not apply for permits – as long as the neighbours don’t complain, it is usually fine.

However, if your use is more high profile or a commercial vacation rental business, you may need to obtain permits.

Every province, and every municipality, may have different rules and requirements. Our engineer reports for the load rating, as well as the engineered platform plans, are usually sufficient to satisfy the authorities. We will do our best to assist with the process, however we cannot guarantee that the building department will be open to these alternative structures. In some cases, additional engineering studies are required.

What about the door?

Our domes are designed with an opening and attachment bars to accommodate a standard, 34'80x or 36x80” pre-hung exterior door which are available at any building supply. We recommend a metal door as they are affordable and very durable in the elements. You will be able to choose between a variety of window options and paint it the colour you like. To install it, you just need to create a simple 2x6 frame and bolt the dome frame attachment bars into it. This means 3 pieces of 2x6":

2 pieces of 82 1/4" for the sides

1 piece of for the top 39" for 34" door, 41" for 36" door, or . This piece goes on top of the other 2 pieces.

The door attachment bars of the dome frame are fastened into the 2x6 door frame with screws and washers or GRK fasteners.

Then the outer and inner cover layers are fastened to the door frame with trim.

If your door has a somewhat different size, you can accommodate for the difference with the wooden frame or some blocking - this is an easy and versatile solution that only requires some very basic carpentry skills. We recommend a 34" door for the 16' dome, the other sizes can accommodate both door sizes by simply angling the frame bars accordingly.

CARE AND MAINTENANCE

 

The cover lifespan is about 10 years or more depending on UV exposure. 

You can easily get a replacement cover when the time comes and enjoy it for another 10+ years. 

The frame will last indefinitely as long as it is not exposed to excess moisture or salty air!


You can use a sponge and soap, or easier yet, a pressure washer, to get any debris and algae off your dome. It will come nice and clean again even after years! 

Sometimes, there can be soot from the chimney that leaves grey streaks which are a bit harder to clean and may require some scrubbing with soap or bleach. 

Scrub the window with a non-abrasive sponge and soap or window cleaner. 

If you have the older pleather liner, you can clean it with a damp cloth and soap if needed - make sure not to scrub too hard. 

Our new Oxford Fabric liner comes in multiple sections that can be easily washed in any standard home washing machine.

 

Since the dome cover is impermeable and creates a moisture sealed space, it is important to remove excess moisture from the air in order to avoid any mold or mildew problems. 

If you have a kitchen or bathroom in the dome, install an exhaust fan to draw out the moist air. We can provide the flashing kit to install any vent pipe wherever you may need it. 

A solar fan will help keep airflow going year round while also helping with excess heat in the summer. 

We highly recommend using a dehumidifier regularly especially in the colder months to avoid any moisture buildup. 

It can be a good idea to spray some anti-mold-spray around the bottom edge of the inner cover especially behind furniture and appliances, and clean regularly. 

What if I get a hole or leak?

Holes or leaks are easily fixed with a specialized Vinyl Glue and a patch. Your dome will come with a patch kit, if you need more, just reach out to us!

What about the panorama window?

Panorama window disclaimer:

The panorama window is a flexible, clear Vinyl that is strong and UV resistant and won’t yellow. 

However, it will have some wrinkles and unevennesses that may smooth out over
time with heat and sun exposure, but not completely disappear. 

Your view will be somewhat blurry, but still beautiful and bright. 

This is normal and to be expected for the low cost. 

We are currently working on some upgrade options for a more high-end, glass or polycarbonate window - stay tuned. 


Zip-off window disclaimer:

The zip-off panorama window can be opened partially or removed fully during the hot season to allow for more airflow. 

However, it should not be opened too frequently as a zipper can wear out over time. 

It is very important to always make sure there is no tension on the zipper when opening or closing it:

- release the tension on the hooks below the window

- have one person hold and pull the window up while the other moves the zipper so there is no tension on it


We do not warranty any damage to the zipper due to improper or excessive use.
