Structural Insulated Panels
Walls and roof panels that do more than frame the shell.
TOPOvue uses Thermasteel steel structural insulated panels for the ADU shell. Light-gauge steel members are bonded with EPS, creating a panel assembly that combines structural framing, insulation, sheathing, and vapor-barrier performance in one system.
Factory-made panels sized and engineered around the kit.
No separate vapor barrier layer is required by the panel system.
High insulation value
The wall and roof panels are designed to reduce heat transfer and support efficient heating and cooling.
Thermally broken steel
Steel members are arranged to limit thermal bridging while keeping the panel strong.
Fire and mold resistant
Thermasteel lists the panels as smoke and fire resistant, mold resistant, and non-combustible.
Ready for finishes
Siding and roofing install over the panel system, leaving interior and exterior style choices open.
Site options
Set it where the property makes sense.
The same ADU kit can be planned for a slab foundation, a pier and beam foundation, or a trailer platform. Engineering and permitting requirements vary by location, so the quote process starts with your property details.
Slab foundation
A straightforward permanent installation for prepared residential sites.
Pier and beam
A flexible path for slope, drainage, crawlspace, or lighter site disturbance.
Trailer platform
A mobile-ready route when the project is designed around a trailer base.
Build sequence
From delivery to enclosed shell.
The kit is made for owners who want a direct build path: do it yourself with the provided video instructions, or hire a basic general contractor to manage the site, utilities, and finish trades.
Confirm engineering
Share the property location and project path so the kit can be engineered for the site.
Prepare the base
Build the slab, pier and beam foundation, or trailer platform before kit delivery.
Set wall panels
Use the video guide to position, align, and fasten the wall system.
Install roof and windows
Enclose the shell with roof panels and the supplied window package.
Add siding and roofing
Install the exterior siding and finished roofing over the kit system.
Finish the interior
Run utilities, choose your finishes, and build the space for your use case.
Renderings
Exterior presence, interior warmth.

Permit-ready plans
Permit-ready plans built for your location.
Permit requirements vary by location, but we make the process easier. Each package includes engineering for your specific site, along with CAD drawings, elevations, renderings, and 3D model files to help communicate the project clearly from quote to build.
