Sing Core SIP Sale and Free Book

The Sing Core company, and builders of the Sing Tiny House, are having a clearance sale on their reinforced structural insulated panels and are also giving away a free book on tiny houses, “Sing a Song of Tiny House“, about the tiny house “rebellion” and the benefits of their lightweight panels.

The structural panels are on sale for $128 each and are being sold in minimum packs of 20. The panels can be used to construct all four sides of an average tiny house on wheels. Each panel is 4×8 feet and 1.5 inches thick and are fully insulated. The sale is good until the end of February 2015.

The benefits of panels include high strength (they have been tested at 660 PSI), an R-value of 6.5 per square inch and they are lightweight. They are also easy and quick to build with. The walls, floor and roof of Sing Tiny Homes are built in less than four hours. The company also construct custom panels made of wood, plywood, aluminum, metal and cement board.

If you have a specific size tiny house in mind, the company also sells various kits that are currently being offered to the Tiny House Community for 50 percent off. Sizes include 8×8 feet, 8×12 feet, 8×16 feet, 8×20 feet and 8×24 feet.

R ten for insulation is way below standard
would be cold in north half of US

    A 2000 sq. ft. home with R-21 insulation could cost $600 per month to heat in the winter.

    While an un-insulated tiny house is only 120 sq. ft. and can easily be heated for as little as $1 per day with a small electric space heater.

    Sing RSIPS can be customized to meet the R-value that you desire for your tiny house design.

    In many cases tiny house builders use standard Tiny House RSIPS and modify them slightly for added insulation in the roof and floor by sandwiching an extra later of foam between 2 panels for extreme weather insulation in areas like Alaska as an alternative to using a custom panel.

    Sing RSIPS are extremely popular throughout Alaska due to being able to quickly build an insulated structure quickly, and cost of transporting and handling materials is less expensive (especially in remote areas) not requiring standard 2×4 framing.

$128 for a 1.5″ SIP (which I would be hesitant to build anything with) is not what I’d consider a “Sale” price. Compared to competitor’s prices, this would be regular priced.

    SIPS were (and still are) a good design. Sing RSIPS are manufactured in the USA and when you factor in the embedded torsion box and foam composition, these patented panels are a value at ten times the price.

kind of confused about their “kits”. The regular price of their 8’x16′ kit is $7680. But their website states “This offer is not for a Tiny House kit, no instructions are provided. This is for pre-manufactured… insulated structural panels”

An 8×16′ tiny house would use approx. 12 of their panels. That means that the price of each panel in their “kit” is $640! That seems crazy expensive. traditional stick construction of walls would cost only a fraction of that price.

But then the sale price stated above for each panel is $128. Am I missing something? Is there more in the kit that is not a kit than just the panels?

We built our house out of sips and 1.5″ is way too flimsy. Sips should be thick enough that you can join them and frame out your window bucks with 2 x4’s. Also not sure what the little strips of wood in the foam are doing there…

    David Singcore - January 27, 2015 Reply

    This is true. SIPS have very little structure strength, unlike Sing’s RSIPS which were independently strength tested at the University of Washington and rated at 660+ PSI (which is stronger than steel pound for pound).

    If you visit Sing’s site, you can see thin 1-inch thick wall panels supporting huge upper structure and roof beams with no additional support except the 1-inch panels themselves. Very impressive.

    Another advantage of being able to use a panel that is so thin is that space is precious for any tiny house meaning more useable space inside the house for the homeowner.

    The strips of wood within Sing RSIPS are actually a huge component of the structure strength of these patented panels. These strips are constructed of vertical grain wood and form small boxes for the torsion box core resulting in superior strength.

    Then he packs the voids of the torsion box (that would traditionally be left hollow) wall-to-wall with solid foam strengthening his panels exponentially.

I can get 4-1/2″ SIP’s for a comparable cost. These panels look as if they have a thermal break every few inches? If so, that defeats one of my main attractions to Structural Insulated Panels.

    Rico - January 27, 2015 Reply

    Yeah.. I think you’re being generous. Those gaps in the polystyrene are inconsistent and maybe a quality issue. PS is also not as durable or strong as Polyurethane foam typically used by SIP producers.

“…walls, floor and roof…” Floors? You can walk on these?

    David Singcore - January 27, 2015 Reply

    Sing’s site has a photo of 20 ft. x 5 ft. 1-inch thick panel with two people standing on it (any other type of SIPS would collapse even without people).

    The structure strength of Sing’s RSIPS are an excellent resource for flooring and is used in many high-end (multi-million dollar) homes.

    You could combine two or more standard Sing RSIPS for added R-value or strength or have custom panels designed per your specifications.

So how does plumbing and electric work with these panels being so thin?

Rob Mair - January 29, 2015 Reply

SIP’s are the only way to go with THOWs. I have done enough building and research to know that for a self build they are so quick and easy to work with.

If constructed correctly they will not move unlike stick construction which is a technique for static buildings.

Check out coolroom SIP panels. They are strong, pre-painted and you only need to clad them if you desire an ascetic finish.

I understand that budget is important but in some areas of building a THOW one must spend for the long term good of the project.
