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.
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.
- Measure the width, or the shorter side, of your framed rectangle to the nearest 1/8”.
- Measure the length, or the longer side, of your framed rectangle to the nearest 1/8”.
- Determine if you’d like to have a light ring.
- Choose the style of your elongated ceiling dome: soft, half-circle or elliptical. Note the Height required for each style.
- If you choose the soft style, determine your height.
- Enter the location (place) where the elongated dome will be installed in your project (for example: Entry, Study, Hall, #1 Elongated Dome).
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.
How to Drywall an Elongated Dome Ceiling
Drywalling an elongated dome ceiling is comprised of: measuring the curvature of the dome rafters and creating the pie shaped pieces that are created from the separation of one rafter from another along the outer ring; measuring the curvature of the barrel portion of the elongated dome ceiling; measuring the curvature of the outer ring and light ring (if applicable), cutting the drywall to the curvature and length, forming and fastening in place.
- Wetting the back of the drywall (as shown in the video) will make the drywall easier to bend.
- For tighter radius elongated ceiling domes, consider using a double layer of either ¼” or ¼” flex drywall.
How to Finish an Elongated Dome Ceiling
Drywall, plaster, tile, brick veneer, trim, mural, faux…the list is seemingly endless. Whether you want your elongated ceiling dome to have a simple or an ornate finish, the choice is yours. All of our elongated dome kits can be designed to handle any finish you can imagine. Plus, they readily accept chandeliers.
Elongated Dome Ceiling Specifications
While any part of an elongated ceiling dome can be modified to our builders’ exact specifications, the most common part specifications for the outer ring, light ring, dome rafters and elongated dome tie are as follows:
|Material||Medium Density Fiberboard (MDF)(High Grade Moisture Resistant)|
|Outer Ring||The outer ring is normally 1 ½” thick and 3 ½” deep (tall) for the half-circle style or 1 ½” thick and 5 ½” deep (tall) for the soft and elliptical style.|
|Light Ring||The light ring is 1 ½” thick and 5 ½” deep (tall).|
|Rafters||Depending upon the size and style of the elongated dome ceiling, the thickness of the rafters can vary from 1” – 1 ½” thick and the depth can vary from 2” – 2 ½” thick. The quantity of the rafters depends upon the size.|
|Dome Tie||The elongated dome tie will change in size and shape to adequately account for the quantity and thickness of rafters.|
|Purlin Ring||Elongated dome ceilings larger than 18 foot may require an additional supporting ring, called a purlin ring, that sits atop the rafters and ties into the elongated dome tie for added support.|
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.
