What Are SIPs?

The Smarter Way to Build

Structural Insulated Panels (SIPs) are transforming the way buildings are constructed — and Enercept is leading the way. If you're new to SIP construction or want to understand the basics, this page is for you.

At Enercept, we manufacture custom SIPs that combine framing, insulation, and sheathing into a single high-performance panel. Our SIP systems simplify construction, reduce energy costs, and provide unmatched strength and efficiency — making them the smart choice for residential, commercial, and agricultural builds.

Understanding SIPs: What Are Structural Insulated Panels?

SIPs are a composite building material made up of three key components:

  • 1

    A solid EPS (Expanded Polystyrene) insulation core

  • 2

    Two outer layers of 7/16” Oriented Strand Board (OSB)

  • 3

    Laminated together under factory-controlled conditions

These panels are used to construct walls, roofs, floors, and foundations, providing superior thermal performance and structural strength in one system.

Why Build with SIPs? Key Benefits

SIPs offer many advantages over traditional stick-framing, especially when manufactured to Enercept’s high standards.

Our panels deliver:

  • Faster Construction

    Panelized systems reduce build time

  • Reduced Labor Needs

    Less framing, insulating, and sheathing work

  • High R-Values

    Exceptional energy efficiency and airtight performance

  • Stronger Structures

    SIP walls are up to 2.5x stronger than stick-built walls

  • Lower Energy Bills

    Save up to 60% on heating and cooling

  • Cleaner Job Sites

    Minimal material waste

  • Healthier Indoor Air Quality

    Tight envelope reduces dust and allergens

  • Green Building Compliance

    Supports LEED®, ENERGY STAR®, and Net-Zero goals

SIPs vs. Traditional Framing: A Smarter Building Method

How do SIPs compare to traditional stick-framing? See for yourself:

Feature Enercept SIPs Traditional Framing
Build Time Fast (precut panels) Slow (onsite cutting)
Labor Requirements Reduced High
Energy Efficiency Up to R-50 Varies by insulation
Air Tightness Superior Prone to leakage
Job Site Waste Minimal Significant
Structural Strength High (laminated panels) Moderate
Cost Over Time Lower (energy savings) Higher (operating costs)

SIPs outperform stick framing in every major category — and Enercept makes it easy to get started.
