|
Moisture Resistance: Resists water absorption and does not provide a nutrient source for molds. |
|
Polystyrene and Polyisocyanurate insulations help manage energy loss and moisture. |
|
Strength and Durability: Rigid insulation maintains integrity during installation and for years after, yet easy to work with. |

Thermal Imagery Study |
|
Study conducted by DOW INSULATION. Images and data are provided by the Dow Insulation web site. |
|
This house is stick built and insulated with R-13 Batts. The image shows all the areas of heat loss, the most being through the windows and the studs. |

|
This is an image of the same house covered in only 1/2” of polystyrene rigid insulation. You can see how much energy is being saved with only 1/2” of additional insulation. |

Home Energy Facts... Home heating and cooling payments are the single largest payment for families after mortgage. Houses use twice as much energy and emit twice as much CO2 as cars. Energy bill for an average family in the U.S. has increased over 30% since 1998. America spends $131 billion each year on household energy costs. |
|
Cavity Insulation is Limited… Fiberglass insulation can only insulate where there are no studs or other mechanicals in the wall. So without sheathing you’re without insulation anywhere there’s just wood. Even wet spray cellulose can’t insulate the wood framing and its also limited by electrical, plumbing and HVAC ducts. Without insulated sheathing, a quarter of your walls are not insulated! So in a square house, that’s the equivalent to one whole wall! |

Our insulated panels are highly efficient and easy to apply to your timber frame structure. We use polyisocyanurate insulation, rated at R-7 per inch of thickness, or polystyrene insulation, rated at R-5 per inch of thickness. That’s up to 50% more efficient than conventional stick built homes. Building with panels reduces construction time and jobsite waste. So not only are SIP’s going to save you money in energy costs, but in construction costs as well. We manufacture our SIP’s using industrial strength adhesive to laminate the insulation to various substrates, in curtain wall or structural panel forms. Panels come cut to fit and with designated wire chases and window and door cut-outs. We supply all fastening material with every panel job. A panel schedule is provided to follow, simplifying the application process. Whether you’re a Do-It-Yourself builder or you’ve hired a contractor, the process is simple and fast! So how’s that for a change, building green and saving money! |

Investing in rigid insulation sheathing pays for itself within just a few years by reducing energy loss and lowering energy bills. |
|
R-Value: Rigid insulation covers the entire wall, providing a continuous layer of thermal protection and increasing the overall R-value and energy efficiency.
