Varies due to many factors. Compared to conventional building methods, material costs are about 5-10% higher. Labor costs, However, costs are significantly lower for erecting the panel home, possibly 30-50% depending on geographic location and complexity of design.

Yes, existing plans can be modified to your specifications.

You may send your floor plan and design to us. Each plan is assessed individually, and your Project Manager will contact you to discuss its viability.

All residential projects are considered custom manufacturing and subject to a 50% deposit with order, balance COD.

These costs vary greatly by geographic area, and the choice of interiors, subcontractors, materials, etc.

Structall home?
Electricity: We recommend the exterior wall and roof panels be “furred out” on the inside with 1.5” metal channels or 2x wood framing. This allows electricians to surface mount equipment and wires using conventional parts and techniques. We do not recommend putting chases (horizontal and vertical holes cored out of the foam at certain intervals) into the panels. This weakens the panel and reduces its energy efficiency.
Plumbing: We recommend “wet walls” be kept away from exterior walls if at all possible, otherwise you will have to “furr-out” the wall to accommodate the larger drain lines. Supply lines can be run within the 1.5” space the metal furring channels create.

Yes.

Panels are connected by a perimeter base channel fastened with concrete anchors.

Any traditional finish including stucco, stone/brick veneer, and siding.

The interior is furred out and drywall is installed. Any traditional interior finish can be utilized. Gypsum wall board is a code requirement on the interior of the home.
*Gypsum wall board, cabinetry, and trim are not included in a SBS home package.

Panels are inherently stronger than conventional framing. They are also extremely strong in racking and shearing, which are the primary issues with seismic and wind load calculations.

Please contact your Structall Project Manager for more information.

If you have been to or have seen pictures of an area damaged by a hurricane or even just high winds you will notice that a great deal of the damage consists of partially removed roof finishes and blown out eave soffits. The damaged roof finish starts the roof leaking causing additional damage to the interior finishes like drywall and woodwork. The damaged soffit lets the moisture in, but also allows the wind to enter the inside of the roof. At this point, the roof is in jeopardy of being torn apart piece by piece as the pressure of the wind acts on the many sheathing panels and framing members looking for a weak point.

With metal panel construction, none of this happens. The metal skin on the top side of the panel acts as an irremovable integral moisture and vapor barrier blocking any rain damage after the roof finishes are blown off. The metal skin on the underside of the panel as it passes over the wall to create the eave is water proof and virtually indestructible, the wind has nothing to grab hold of and it cannot enter the home to cause extensive damage.

Depending on the overall design, amount of window area and life style of the home’s occupants one can expect a 30-50% decrease in energy use for heating and cooling a typical home built with panels. This also translates into a 30-50% smaller air conditioning unit.

One advantage is that the metal panel home owner, depending on the insurance company, may receive a discount on his insurance premium for building a wind and fire resistant home.

Another advantage is that the home should receive a better bank appraisal due to the superior level of construction.

Finally, metal panel homeowners have described a comfortable evenness of temperature as one moves throughout the home. This is due to the lack of air leakage and drafts causing some rooms to be colder than others.

• Metal panels are the structure, insulation and moisture barrier in a single installed unit. Wood panels require an additional moisture barrier.
• Metal panels have a tremendous strength to weight ratio, this makes them light and easy to install without heavy equipment like cranes. A wood panel is about twice as heavy as a metal panel.
• Metal panels are essentially unaffected by insects and other pests. Unless you are purchasing a treated wood panel the wood in the panel is a food source for pests.
• Metal panels interlock without the need for an additional framing member at the joint. Wood panels require a lumber or plywood spline at each joint.
• Metal panels have extremely good fire resistance. Wood burns easily.
• Also, since all components of Structall metal panels can be recycled, there is less waste on the construction site. Wood panels are not as easily recycled into an equally valuable product.
• Metal panels do not “off-gas”, in other words the components of the panel do not emit chemical gasses from their manufacturing process in to the building environment. Wood panels are made of plywood and may emit a number of chemical gasses including formaldehyde.

After the concrete slab is poured, the weather tight shell of a single story ranch style home of about 1500s.f. can be erected by an experienced crew of one lead carpenter and 4 laborers in about 5 days. This would be called the dried-in stage of construction with a water tight roof and all exterior windows and doors installed. The equivalent home built conventionally would take about two to three times longer.

Structall's metal SIPs have sheet steel skins that are high-quality galvanized, then primed, and then painted with an incredibly durable polyester finish. It is unlikely through normal exposure to the weather the steel skins would rust through all these layers. Even field cut panel edges are not a problem due to so little exposed raw metal surface area.

Yes, SIPs can be used for internal walls and floors. However, it would not be possible to incorporate plumbing and electrical into the interior walls. Compared to conventional methods, the cost would also be significantly greater with little benefit.

A rotary saw with a metal cutting blade. Cutting one metal facing at a time since it is difficult to cut through the entire panel thickness in one pass.

Yes. The standard 26ga steel panel can be used in seismic zones A, B, C.

Our High-Performance Shear Wall Panel can be used in ALL seismic zones. In this application, the standard 26ga steel panel would be used for the roof and the majority of the exterior walls. The HP Shear Wall Panel would be used only where a shear wall has been specified.

Shingles can be attached to the Snap-N-Lock panels using these methods:

Attach shingles directly to the panels using adhesive.

Attach OSB to panels, apply felt paper, then attach shingles using nails.

5V Crimp Metal Roofing can be attached to a Steel SIP home using this attachment directive:
