Creating relationships with builders is a top priority. A Deltec home is unique in that we do not finish the home. We prefabricate all of the building components in our factory and ship them to the jobsite where it is assembled by a local builder. Therefore, builder recommendations are very valuable to our customers and we’re always looking to add to our recommended Builder’s List.
Builder Support and Resources
In addition to a detailed construction manual, you’ll have access to our in-house 24-hour construction expert who has built over 300 Deltecs and is available to answer any questions day or night. We can also connect you with an on-site field consultant to guide the assembly of your shell. Finally, each year we offer an on-site builder training class lead by our expert, allowing you to get firsthand experience with the assembly of a Deltec shell.

Frequently Asked Questions
What does the Deltec package include?
The Deltec package includes the structural shell for the home, from the sill plate up. Deltec does not provide the foundation, mechanical, electrical, plumbing, interior insulation, interior finishes, or roof shingles. The Deltec drawings provide room layout information to assist with the construction process.
What type of foundation can I use?
Deltecs can be built on any type of foundation. Common foundations include slabs, elevated slabs, pilings, crawlspaces, and basements.
How do I lay out the foundation?
We provide a benchmark that serves as the building's center. Dimensions are provided from the benchmark center to the edges of the foundation at the corners, as well as indicating the angle between the panel corners.
Where does the foundation stop and the Deltec system begin?
The Deltec package covers everything structural above the sill plate. The contractor or owner provides the foundation system and sill plate, on which the Deltec floor system rests. For buildings on slab, a pressure-treated sill plate is built into the Deltec wall panels, and no additional sill plate is required.
How is the building tied down to the foundation?
For buildings on slab, the wall panels are anchored directly to the slab using Deltec-supplied concrete screw anchors. For all other foundations, Deltec supplies truss ties that attach the floor trusses to the contractor-supplied sill plate, as well as nails to attach the extended wall skirt to the truss ribbon boards.
How are the wall panels connected together?
Wall panels are connected by metal nailer plates, usually three on the vertical face of the connection and one on the horizontal face at the top of the walls.
How are radial trusses installed?
Floor trusses are installed in order around the circle, meeting at the center around the benchmark location and spaced at 2 ft. on center at the outside ends. Ribbon boards are applied at the top and bottom chord locations along the exterior end to ensure stability of the trusses.
What hardware is included for the floor system and what do I need to provide?
We provide all required hardware for the floor system, including truss ties and truss bridging, with the exception of nails for the floor sheathing. We provide information about the nail size and type and the contractor then purchases nails that work with the specific nail guns to be used.
What roof hardware is provided and what do I need to provide?
Deltec provides all required hardware for the roof system installation, such as truss ties at the wall, the ring and collar roof system, and the returnable erection jig. As with the floor sheathing, Deltec does not provide roof sheathing nails, but the required size and type are given.
How are the roof trusses supported and connected?
Roof trusses meet at a central steel compression ring. A steel tension collar is installed around the outside of the vertical king posts, at the bottom of the trusses, which ties the roof trusses together and removes any lateral thrust from the system.
How do I cut all the plywood to fit? What does Deltec provide?
The lower layer of floor sheathing is provided by Deltec and precut to follow the angle of the trusses. The upper layer of sheathing is provided by the contractor and is laid in full sheets after the installation of the exterior wall panels but prior to construction of the interior walls.
How do I assemble the self-supporting roof system?
The central steel compression ring will be supported by a temporary erection jig, which also supports the trusses until the steel tension collar and roof sheathing have been installed. The erection jig separates into pieces and can be returned to Deltec for a refund of the deposit.
The customer plans to carry heavy loads like a large library, a rock collection, hydronic radiant floor heat, thick ceramic tile flooring, etc. Can the floor trusses carry that additional weight?
When large loads are expected, we recommend the use of our High Dead Load Floor System, which includes trusses designed for up to 30 psf of dead load. Higher dead or live loads in commercial buildings can be accommodated by our Commercial Load Floor System. Talk with your Project Manager for more information.
What type of equipment do I need? How heavy are the panels?
Wall panels can weigh up to 800 lbs. Because of this and for ease of construction, we recommend having an all-terrain forklift with an extendable boom and/or a crane to assist with panel installation, especially when building on piles or a second story.
How do I install the windows?
Deltec can install windows in wall panels here in our factory. Deltec follows strict requirements for installation of flashing and tape to ensure the tightest installation possible. If Deltec is installing siding, we can also install the window trim in our factory. Doors and windows mulled to doors are to be installed on site.
Where do I locate the mechanical, electrical, and plumbing systems and ductwork?
Mechanical, electrical, and plumbing work can be installed on-site just like in a conventional building. There is a mechanical chase in the center of the floor trusses to assist with locating MEP runs. As with conventional construction, floor and roof trusses may not be altered without the express written consent of Deltec Homes.
Is there anything unique about finishing a Deltec after it is dried in?
Finishing a Deltec is no different than finishing a conventional building.
Are there any special requirements for inspecting a Deltec building?
The Deltec system is an open-panel system, meaning that once the structural shell is assembled, it can be inspected in the same manner as if it were entirely site built. Mechanical, electrical, plumbing, and insulation are all installed on-site as in conventional construction, leading to ease of inspection.
