Expandify internal walls are solid panel systems, not hollow like conventional timber-frame walls.

They are made from Structural Insulated Panels (SIPs) with:

A solid insulation core

Bamboo composite internal surface

Integrated cavities for electrical wiring

This construction method:

Enhances strength and thermal performance

Eliminates the need for traditional framing and plasterboard

Allows for flush-mounted electrical points and switches

No stud framing is used internally, so hanging heavy fixtures or installing wall-mounted cabinets requires appropriate wall anchors or builder assistance.
