OSB+EPS+OSB Structural Insulated Panels
What is an OSB+EPS+OSB SIP?
An OSB+EPS+OSB SIP is a high-performance Structural Insulated Panel composed of a solid Expanded Polystyrene (EPS) insulation core laminated between two layers of Oriented Strand Board (OSB). This monolithic structure functions simultaneously as:
-
The structural frame
-
The thermal insulation layer
-
The sheathing system
This integration reduces material waste, shortens construction time, and increases long-term building performance.

Slow, Labor-Intensive Construction?
Our prefabricated SIPs arrive ready to install — no wet trades, no complex framing.
-
Easy handling and fast assembly
-
Perfect dimensional accuracy
-
Fewer workers and shorter timelines
→ Result: Projects completed weeks faster — saving time and money.
Looking for Sustainable, Low-Impact Solutions?
SIPs minimize waste, reduce on-site emissions, and deliver long-term energy efficiency.
-
Made from recyclable, non-toxic materials
-
Supports LEED, BREEAM, and Passive House goals
-
Lower lifetime carbon footprint
→ Result: A smarter, greener way to build — without compromising strength.
Key Features & Technical Benefits
🔹 Superior Energy Efficiency & Insulation (High R-Value)
Our SIPs provide continuous insulation with minimal thermal bridging. With R-values up to R-40+, buildings achieve up to 50–60% energy savings compared to traditional framing.
-
Continuous insulation barrier
-
Airtight building envelope
-
Reduced heating and cooling costs
-
Supports Passive House and Net Zero standards
🔹 Exceptional Structural Strength
The stress-skin design — where OSB faces are bonded to an EPS core — delivers an extremely rigid and durable panel.
-
Excellent resistance to lateral loads, wind, and seismic stress
-
Ideal for extreme climate conditions
-
Long-lasting and low-maintenance
🔹 Fast, Efficient Construction
Prefabricated and precision-engineered, SIPs enable dry construction and quick on-site assembly.
-
Reduced build times by weeks
-
Minimized on-site labor and waste
-
Lower project costs
-
Consistent quality and precision fit
🔹 Eco-Friendly & Sustainable
SIP construction reduces energy consumption and environmental impact.
-
Energy-efficient operation reduces lifetime carbon footprint
-
Manufactured with minimal waste
-
Supports Green Building certifications
-
Non-toxic materials ensure a healthy indoor environment
