Structural Insulated Panels (SIP)

The SIP Construction System is an advanced, prefabricated building technology that ensures efficiency, strength, and sustainability. These panels, made of rigid insulation sandwiched between structural facings, provide high thermal performance, airtightness, and structural integrity, significantly reducing energy consumption and construction time. With superior load-bearing capacity, soundproofing, and resistance to moisture and pests, this system enhances building quality and durability. Its modular design supports flexibility and rapid assembly, delivering a cost-effective and eco-friendly solution for residential and commercial projects.

Starting at only 3 million IDR/m².

Included: Walls and roof, ready to finish.
Not Included: Foundation, MEP, plastering, coatings, doors, or windows.
