ELONGATED DOME CEILING SPECIFICATIONS

What do you do when you want a dome ceiling but your space is too rectangular? Simple, you choose an elongated dome ceiling. The profile of an elongated dome resembles that of a racetrack which gives you the freedom to add a touch of flair that looks purposeful without the fear that it will look off-centered in your rectangular space.

Material

Medium Density Fiberboard (MDF)
(High Grade Moisture Resistant)

Dome Tie

The elongated dome tie will change in size and shape to adequately account for the quantity of rafters and ensure proper spacing along the outer ring.

Purlin Ring

Ceiling domes larger than 18 foot may require an additional supporting ring, called a purlin ring, that sits atop the rafters and ties into the dome tie for added support.

HOW TO MEASURE AN ELONGATED DOME

Measuring a space for an elongated dome is pretty straight forward. It simply consists of measuring the width, length, determining if you want a light ring, choosing your style, naming it with a location and understanding your total height. 

  1. Measure the width, or the shorter side, of your framed rectangle to the nearest 1/8”. 
  2. Measure the length, or the longer side, of your framed rectangle to the nearest 1/8”. 
  3. Determine if you’d like to have a light ring. 
  4. Choose the style of your elongated ceiling dome: soft, half-circle or elliptical. Note the height required for the half-circle and elliptical arch styles along with the suggested height of the soft style. 
  5. If you choose the soft style, determine your height. 
  6. Enter the location (place) where the elongated dome will be installed in your project (for example: Entry, Study, Hall, #1 Elongated Dome).

CHOOSING AN ELONGATED CEILING DOME STYLE

Choosing a style for your elongated dome is mostly personal taste along with the overall design/theme of the home. The style of an elongated dome is the unique shape of the dome rafters: soft, half-circle, or elliptical. Most of our builders prefer the soft style as it provides the most flexibility in height. When you choose the soft style, we provide you with our suggested height, but you ultimately have the freedom to choose the height you want, or are potentially limited to, by the pitch of your roof or truss design. In contrast, when you choose either the half-circle or elliptical style, the height is mathematically predetermined given the size of the box and the style you’ve chosen.

HOW TO INSTALL AN ELONGATED DOME CEILING

Installing an elongated dome ceiling simply consists of marking the placement of your outer rings and light rings (if applicable) and then fastening the rings into place. Once this is complete, you will need to connect the rings with a 2×6 (sometimes a 2×4) to complete the racetrack profile of your elongated dome. Next you’ll need to set the elongated dome tie centered at the total height, which will be detailed on your instructions. Lastly, you’ll need to fasten the rafters to the elongated dome tie as marked and to the outer ring as specified in the instructions.

FAQ

How long does it take to get my elongated dome ceiling?

Elongated dome ceilings normally take 10 - 14 business days to manufacture (in most cases sooner). Then add a few days for shipping. Plan for 2 1/2 to a little over 3 weeks from date of order.

How do you drywall an elongated dome ceiling?

Drywalling a elongated dome ceiling is comprised of measuring the curvature, cutting the drywall to the curvature, forming and fastening in place. You can also watch our "How to Drywall a Dome Ceiling" YouTube video.

QUICK TIPS

  • Wetting the back of the drywall (as shown in the video) will make the drywall easier to bend.
  • For a tighter radius, consider using a double layer of either ¼” or ¼” flex drywall.

How do you finish elongated dome ceilings?

Drywall, plaster, wood veneer, brick veneer, trim, tile… the list is seemingly endless. Whether you want your elongated dome ceiling to have a simple or an ornate finish, the choice is yours. You can also watch our "7 Creative Ideas to Finish Your Ceilings & Archways" YouTube video.

what our customers are saying

We’re a fan of the groin vault kits from Archways & Ceilings. We have been using them for a few years now and the quality and the ‘WOW’ factor their groin vault kits create are well worth the cost. Plus, their customer service is excellent!

Nick Fisher/ Owner

Dream Structures LLC, Springdale, AR

We were absolutely satisfied with our dome ceiling. The service and communication we got from Archways & Ceiling was top notch. We would highly recommend working with them and using their products.

Nuchem Grunhut

Done Right Construction, Monroe, NY

I would highly recommend Archways & Ceilings for coved ceilings. Their kits takes what can be a hard task for a carpenter and makes it into a simple project. The savings over other products we have used like Styrofoam is significant with better durability.

David Hanson

Hanson Carlen, Spokane, WA

Archways & Ceilings does a great job on all of their products. Specifically, we have been using their barrel vaults exclusively since 2009 and the exact precision with which they are made cannot be replicated in the field by traditional stick framing methods. For a truly high-end finish and a shape nothing short of perfection, Archways & Ceilings materials are the way to go.

Les Owens

LRO Residential

Archways & Ceilings is a great company to have as a resource.  We know that when we take on projects that require a variety of arched ceilings, we can count on them to come through.  We recently completed a project that required an elliptical barrel vault that intersected with 6 half circle arches at different heights which they call “Igloos.”  This ceiling came out terrific and came out like the architect spec’d.
