SIP Panels Structural Insulated Panels

SIP Panels Stronger than Steel Reinforced Structural Insulated Panels

Can SIPs be stronger than steel? Introducing the next evolution in SIP panels, the Sing Reinforced Structural Insulated Panels (RSIPs). The SIP panels have been gaining popularity among many phases of construction from tiny houses to panelized homes, commercial buildings and temporary shelters that can be manufactured in very little time while providing full insulation.

SIP Panels Structural Insulated Panels

SIP Panels

Traditional SIP panels come in a standard 4×8 configuration with a thickness of four inches. The standard SIP panels feature OSB skins sandwiching a foam insulation material, such as EPS foam, resulting in a preconfigured SIP wall panel which can be quickly and easily assembled. While offering the convenience of a preconfigured wall panel, the lack of strength has left a void in the SIP industry for insulated panels.

Reinforced SIP Panels

That’s where Sing Core comes in. Sing Core is a patented torsion box core, when combined with EPS foam creates a solid substrate which is stronger than steel pound for pound, independently rated at 660+ PSI. The insulation and strength of these reinforced SIP panels has found them to be exceedingly effective in all forms of high precision and high performance construction methods, where climate control, sounded deadening, high precision and rapid construction time are of primary importance.


Far from being a highly disposable or one-time build, these Reinforced SIP panels are built to last and can be reused over and over again in even the most strenuous climates and conditions. United States Navy expeditions, who would build temporary structures then burn them to the ground following their assignments, are now using Sing Reinforced SIP panels. Enabling them to disassemble the structures, flat pack, transport, and store the reusable components between assignments. Sing components are built to last for superior ecological responsibility and sustainability.

Lightweight Reinforced SIP

Sing Reinforced SIP Panels are constructed with the patented solid composite substrate which is lightweight are made in the USA, constructed with plywood faces (not OSB) for superior performance without compromising the weight. No other Eco-friendly, high strength SIP can compare in terms of weighing in at a fraction of other solid heavy weight panels.

High Strength SIP Panels “Even under 1,500 lbs. load show very little deflection”

High Strength Reinforced SIP

No other conventional SIP is as strong as the Sing Reinforced SIP. The standard reinforced Sing 4×8 structural insulated panels are three inches thick, feature solid wood edging and can easily survive strenuous strength tests, like this one, where even under 1,500 lbs. load show very little deflection. No other SIP can compare in terms of unmitigated high strength as Sing SIPs panels are stronger than steel pound for pound.

SIP Walls

One of the best and fastest ways to divide a space is by using reinforced SIP walls to separate two or more adjoining areas. This is an excellent solution when used as SIP room dividers. Using your reinforced SIP wall panels as room dividers is the best of all room divider ideas because of the lightweight, high strength and insulation provided by your Sing SIP walls. Most of our SIP walls used as room dividers are found in the greater New York area, but could be used anywhere you want to create a separated room area within an existing living space.

SIP Loft

The strongest reinforced SIP panels ever made are Sing 4×8 SIPs that are 3 inches thick, the easiest, fastest, simplest way to make a super strong loft on-the-fly. Create a warehouse loft, factory loft, garage loft, barn loft, apartment loft, house loft, tiny house loft in minutes without the need of any joists or framing – only Sing Core can do that.

SIP House

You can design and build your entire home out of Sing Core, and many have built their ultimate high end tiny house as well as luxury Sing homes and estates built entirely with patented Sing Core technology. Be aware that if you are designing and building your own SIP house and plan to use Sing Core, keep in mind that we do not offer any design or configuration support as we only provide this stock 4’ x 8’ x 3” SIP panel, and build other panels as requested to architectural specifications.

SIP House Regulations

Building an SIP House is subject to the codes and conditions required by the powers that govern the geographic location of your SIP house building site. It is likely that Sing Core is not covered by your local IRC (International Residential Code) and may need to have your SIP house plans drawn up and architect or engineer approval stamped to obtain the proper permits for your SIP homes.

Tiny House Regulations

Tiny house regulations vary from location to location, and some municipalities are endorsing alternative housing, such as sing tiny houses, for recreational use, homeless shelters, emergency housing and local domiciles. In many areas structures under 1,000 sq. ft. are exempt from building permits, but may not apply to your area, so check with your local municipality before you get to building your Sing tiny house with reinforced SIP panels.

New SIP Structural Insulated Panels Sips

SIP-structural-insulated-panels-sipsSIPs are Structural Insulated Panels that are a technology that helped to revolutionize the light construction building industry by using pre-panelized components to build entire structures.

Each Structural Insulated Panel (SIP) is manufactured featuring a foam core sandwiched between two OSB (Oriented Strand Board) skins. The thickness of each completed SIP starts at 4-to-6 inches and goes up from there.

SIPs are structurally stable, insulated and reduce construction labor costs.

While SIPs are being widely accepted in the home and green building community, a revolutionary, new patented design improves on the SIP concept significantly.

Homebuilders using SIPs for their exterior walls are now seeking out new alternatives for thinner but stronger internal components like walls, ceilings and floors made of Sing patented reinforced structural insulated panels.

Patented Sing Reinforced Structural Insulated Panels (SRSIP)

SIP-Sing-Insulated-Panels-sips-panel-made-in-USAInventor, Peter Sing, envisioned a fusion of old and new technologies into a hybrid composite building material that is the affordable Eco-friendly solution to limitations of traditional building materials challenging architects, designers and contractors today.

Sing’s patented design features an improved wood torsion box core that has been known by woodcraftsmen to offer strength and stability for centuries.

This newly invented core bonds wall-to-wall foam to fill the torsion box voids and exterior surface materials together creating a solid Eco-friendly composite that is lightweight and stronger than steel pound for pound.

Due to the built-in torsion box structure, much more structural strength can be achieved using less material, reducing the weight and thickness of Sing patented reinforced structural insulated panels. See specs

Sing patented reinforced structural insulated panels start at ¾-to-1 inch in comparison to standard SIPs that start at 2-to-4 inches thick.

Sing Panels enable the builder to create designs that are frame-free because the built-in torsion box structure is more dimensionally stable than a standard stick-framed structure and they are pre-insulated for energy efficiency and sound deadening qualities.


Sing patented reinforced structural insulated panels can have over 700 PSI compression strength in comparison to the standard foam used in SIPs which rates at about 15 PSI. There just is no comparison to Sing’s torsion-box-hybrid.

This superior strength enables Sing patented reinforced structural insulated panels to outperform other material and has already established a demand with high-end millworks for excellence in maintaining true flatness over long spans, as true flat doors or counter tops over 16 feet in length cannot be affordably lightweight, or straight over long spans, or resistant to warp, twist or rot without using patented Sing Core, which is structurally guaranteed for 10 years, is easy to repair and designed to last for lifetimes.

In fact, if your Sing patented reinforced structural insulated panel is damaged for any reason (even if it’s your fault) we will repair it to its original structural strength.

Sing patented reinforced structural insulated panels are so strong, in fact, that entire homes are built using them and they are also used in lightweight high-strength post and beam applications.


Sing patented reinforced structural insulated panels are so much thinner than other building materials because of the internal torsion box foam-filled frame structure. While SIPs rely on the exterior stress skin to supply the overall strength of each panel, Sing patented reinforced structural insulated panels have the strength built-in requiring very little from the external material, except to complete the torsion box construction.

For instance, standard SIPs have an exterior OSB skin of .50 inch thickness on either side of the foam core, while Sing patented reinforced structural insulated panels can have an HPL skin of .020 inch. That’s a savings of 96% in exterior materials, but still extremely strong. See comparison to other building materials.

Highly Customizable

Sing patented reinforced structural insulated panels can be built to your specifications. Whatever your specific requirements are for your project, Sing Core can create the exact panel(s) that you need to make your dream come true. This is why the most reputable architects and high-end millworks in the nation seek us out to solve their size/weight/strength challenges.

Many specifications can be customized to meet your needs, like:

  • sing-core-photo-gallery-lightweight-high-strength-ecofriendlyTrue flat (straight) and stay flat
  • Length, width, thickness
  • Weight reduction
  • Surface materials
  • Insulative R-value
  • Insect resistant
  • Sound-deadening STC rating
  • Extreme weather exposure
  • Waterproof
  • Flame retardant
  • Bullet and blast proof
