As The Homeowner Building With SIPs

When building a new home you can't afford to shortcut on the insulation. Because of the high insulation R-values of RAY-CORE SIP Panels, along with the tightness of their joints, savings in energy costs are significant over the life of the structure. Studies show that owners can save 60% or more on heating and cooling costs every year. With savings like that you will be putting money back in your pocket in less than three years.


Choosing The Right Contractor For The Job


Innovative contractors love our product! RAYCORE utilizes standard building practices that have been proven for hundreds of years (rafters for roofs, double top plates, single bottom plate, headers, king studs, and trimmers for walls). Because RAYCORE is improving standard building practices and not “reinventing the wheel” no special tools or training are needed to use this energy saving roof panel, wall panel and insulated header system. Just choose your favorite contractor.

Here are five questions you might ask yourself and the contractor before you commit to a builder:

1. Is this builder just trying to sell me a house and not a home?
2. Does this builder care about my long term utility bills? 
3. Do they poo-poo energy efficiency and tell you it’s not worth the effort?
4. Ask them to describe some of the energy savings strategies that they have used on recent jobs.
5. Are they more worried about how much they are going to make rather than your desires?


Remember, It's Your Home, It's Your Money...  You're In Charge, Not the Builder!

On average it will cost about $1,350.00 more on a 1500 sq foot home to use RAYCORE's SIP wall panels than sticks and fiberglass or cellulose. This small investment will pay you back in less than three years and keep money in your pocket throughout your life.  Because of the high R-values and tighness of the construction, your HVAC system will be reduced in size and related cost, may to as much as 1/2 and the savings might even make the cost of your panels FREE!  Learn More about Energy Savings.


Real R-Values Of Different Insulations

As with most insulators (cellulose, fiberglass, polyurethane, and polystyrene a.k.a. EPS or XPS,) as the air temperature drops the R-value increases.  As the air temperature raises the R-value decreases. It is important that when you see an R-value you know at what temperature the product was tested. The apples to apples R-value ASTM C518 comparison is 75°F.  If you live in a colder climate, you may be more concerned with comparing the 50°F or even 20°F R-value of the insulators you are considering as many products R-values drastically decrease as the temperatures drop.  RAYCORE's custom blend high density closed cell polyurethane foam is the best performing insulator on the market for cold climates!  Equally, it is a standout in hot climates as well!  The per inch R-values below are in accordance with the ASTM C518 Standards at 75°F. *
