SIPS Platform: Structural Insulated Panel Deck
Along with choosing the size of your yurt, you will need to decide on your platform.
The choice is between:
No Deck/ I’ll build my own - or - Structural Insulated Panel Deck
If you are confused about the difference between the two, have no fear! You are not the only one, and this post should help clear up any confusion.
"No Deck / I’ll build my own" implies that you will use our engineered platform plans and build the round platform to exact specifications. Most people either hire a carpenter or contractor or use one of the many “Rainier Approved” Expert Yurt Installers scattered throughout the country. This type of platform requires a considerable amount of understructure and the circumference must be exactly round and measured within a 3” tolerance of the exact circumference and diameter.
The other option is to purchase at the time you place your order from Rainier Yurts SIPS (or Structural Insulated Panel System) prefabricated deck. Think of it like an ice cream sandwich on steroids! The highly sought-out SIPS Panels are perfect for our yurt platform.
The panels are a 21st-century composite material of expanded polystyrene with 7/16” O.S.B. board (oriented strand board structural sheathing) top and bottom skin that has the highest option for insulation and structural performance in a single building product. With an R-Value factor of R-24, your yurt will stay warm and efficient all winter long and cooler in the summer months.
This platform option requires significantly less material from the lumber yard than traditional platforms and makes building your platform a snap! You can save time and labor costs by going with SIPS. Another advantage is the ability to un-assemble the SIPS if you ever have to move your yurt. These giant puzzle pieces fit together to create one even, solid, sturdy, and long-lasting platform for the yurt to sit on.
How a SIPS Platform Enhances Yurt Stability and Efficiency
SIPS are required for building new schools and commercial buildings in areas with high winds, tornados, and hurricanes because of the intense structural ability. A SIPS yurt platform will be significantly more durable and solid than a non-SIPS. And - bonus! - it takes the guesswork of getting the platform perfectly round as it comes pre-cut in sections that snap together to create the perfect sized and shaped circle.
While conversing yesterday with new yurt owner Sunshine (yes, that is her real name!) she expressed her sentiments about the SIPS perfectly: “Why would anybody NOT get a SIPS?!"
Well, some folks can’t swing the expense in their yurt budget. Let’s face it, these puppies aren’t cheap! But after touring the SIPS manufacturing facility (one of the few components of the yurt that we do not make here at Rainier) about 35 minutes from our manufacturing plant, I quickly understood what goes into making these dense, but lightweight marvels.
They expand the polystyrene foam using steam (heat and moisture) and then form it into the 5 ½ “ thick x the required length panels. These can often be over 23’ long. OSB board is then laminated to the top and bottom of the polystyrene. Then using CAD precision, the pieces are cut to the exact size and shape of each yurt and into manageable sections. The individual sections, which average 4 feet wide by 8 to 11 feet long (the end pieces are usually longer), make it easy to build the platform in precarious places, like over a cliff, over water, at high altitudes, and in inclement weather conditions.
SIPS are maintenance-free, long-lasting, and a dependable source of insulation. If you live in a relatively wet climate, I recommend coating your SIPS on both upper and lower boards with primer or marine-grade paint to seal the OSB prior to putting your SIPS platform together. Some people have used the exposed but painted/polyurethane OSB as their finished floor.
The only downside of getting a SIPS is that they do take up significant room when shipping. But from my angle, it doesn’t cost that much more, and the reward it provides in terms of getting a solid platform with R-24 insulation that is easy to install or relocate is invaluable.
Chat with us to explore whether a SIPS panel will improve your yurt life. I have material lists for both options (SIPS and lumber constructed platform) in all of our yurt diameter sizes so that you can have your local building center quote the materials and compare the costs. The SIPS will always be slightly higher, but when you factor in the time saved with the easy installation, you might find the cost is well worth it.
Enjoy the journey!
