For ADU Builders
Build code‑ready ADUs in days, not months.
MDLR Brands' LiteSIP panel kits let you skip the framing crew and the weather delays. Pick a kit, get financing in place, and start building — most ADU shells go up in a few days with a small crew.

For ADU Builders
Built for ADU schedules and ADU budgets
The same composite structural insulated panels (C‑SIPs) used in our full home kits, sized and engineered for accessory dwelling units.
Stronger, Lighter, Smarter
Ultra-lightweight panels with exceptional structural integrity, so a small crew can install faster and more safely than with conventional framing.
Energy Efficient
High-performance insulation keeps the unit cooler in summer and warmer in winter, cutting tenant energy costs year-round.
Durable by Design
Resistant to fire, moisture, mold, and pests — a long-lasting, low-maintenance shell built to meet rigorous building codes.
Fast & Flexible Install
Prefabricated, panelized to your plans (or ours), with video install guidance so your crew can move straight from delivery to assembly.
Available Kits
