SIPs by RAY-CORE – Eleuthera, Bahamas

SIPs– Insulated Roof Panels by RAY-CORE – Tom McDevitt, an avid surfer, just knew that a home on Eleuthera was for him a “must-have”.  In preparations for construction of his new home, Tom came to RAY-CORE in the spring of 2011 in search of a good roof insulation solution for his planned island home.  Needing a product to meet hurricane standards, withstanding 160 mph winds, RAY-CORE insulated roof panel SIPs was just the answer. In May of 2012, Tom’s new home dream came true.

SIPs Lightweight Structural Insulated Roof Panels

RAY-CORE supplied Tom with its 3-1/2” R-26 polyurthane roof panel SIPs.  In an effort to stand up to Eleuthera’s sever termite problems, Tom requested his roof panels be manufactured with the optional pressure-treated studs.  For added strength against gale-force winds, Tom also chose the 16 inch on-center studs with the optional shiplap connection joint.  These lightweight, 4 foot wide by 8 foot long SIPs panels, weighing

In the Bahamas, beautiful Eleuthera , the word meaning “freedom”, is an island paradise located 50 miles east of Nassau.  The long, slender island runs north and south, approximately 110 miles long and averaging a mile wide, and is home to around 8,000 residents.  Surrounded by warm and crystal clear water, the eastern shoreline is a mixture of cliffs, bluffs and white-sand crescent shaped beaches.  The western side too offers amazing bluff views and beautiful beaches, but it overlooks the shallower and clear blue water of the Great Bahama Banks.  Drawn to the area by the beauty of its water, beach-combing, fishing and surfing are activities that fill resident’s days.RAY-CORE Structural Insulated Panels SIPs are proud to be a part of Tom’s new home in this beautiful island paradise.  A few pictures of Tom’s favorite places borrowed from www.eleutherasurf.com.

Structural Insulated SIP Panel Insulation – Part 3. Compare the Foams

SIP panel insulation is offered in several different forms.  In this post, part 3 of a series of 6 on different types of insulation on the market, we discuss the difference between rigid plastic foam insulations.  In the table below we compare various foams R-values, characteristics and advantages and disadvantages to that used in RAY-CORE’s structural insulated panels.  Just one more step in making the decision when purchasing a SIP panel for your next home.

RAY-CORE uses only the best… super insulating closed cell polyurethane foam in their structural insulated panels.  Different than standard SIPs, RAY-CORE panels take the tried and true construction practice of using studs, fills the voids with high R-value foam, adds a radiant vapor barrier all wrapped up in a modular, lightweight panel with superior strength.  If you would like to learn more now about RAY-CORE’s SIP panel, visit our website by clicking the green button to the right of the screen, or phone 877.552.2440

SIP Panel Insulations - Compare the Foams

Structural Panel (SIP) Comparison to Other Insulations – Part 2. Batt & Blanket Insulation

Our last post we compared structural panel Insulation (SIP) to loose-fill insulation, in hopes to provide an easy way for you to make comparisons.  To continue with this theme, today we are going to explore Batt and Blanket Insulation in comparison to RAY-CORE structural panel insulation by looking at R-value per inch and some of the advanatages and disadvantages.

If you take a careful look at the table below you will see that in comparison to batt and blanket insulation, RAY-CORE’s structural panel insulation (SIP) is far superior. The panelized form offers the added benefit of framing, insulation and wrap all in one structural panel and one step.  To learn more now about RAY-CORE SIPs, visit our website and see how RAY-CORE will pay you back in savings for the lifetime of your home. Click the green button on the right of your screen now or call 877.552.2440 to speak with one of our experienced RAY-CORE representatives.

Structural Panel Insulation by RAY-CORE vs. Batt Insulation

Structural Insulated Panel (SIP) Compared to Other Insulations – Part 1. Loose-Fill Insulation

Comparing structural insulated panel (SIP) to other forms of insulation, can be a long and tedious process, so we thought we would do the work for you.  Our previous post broke insulation down into 6 categories.  To get a better picture of how different insulations compare, the next 6 posts will take these categories and further break them down identifying some of the more common insulation products, compare insulation R-value per inch, and discuss some of the advantages and disadvantages.

Take a look at the table below and compare the superior qualities of RAY-CORE’s structural insulated panel (SIPs) to see why you must consider RAY-CORE when building your next home.  To learn more, visit our website and see why structural insulated panel construction with RAY-CORE is the smart choice.  Just click the green button on the right of your screen now or call 877.552.2440 to speak with a knowledgeable RAY-CORE representative.

CHARACTERISTICS
ADVANTAGESDISADVANTAGES
Fiberglass Loose-Fill2.2 - 2.7 per inchSpun molten glass
fibers

Soft, wool-like material,
Usually pink, yellow or white
* Inexpensive
* Good coverage - fills
hollow cavities, voids,
around framing and
mechanicals
* Works well in attics
* Non-flamable, but will
melt
* DIY Friendly? (If you
don't mind the itch) -
requires blowing
machine
* R-value reduced
by compression, air
currents and
subsequent dust
and dirt
accumulation
* Tends to settle
reducing R-value
* If wet, must be
replaced
* Irritating to work
with - wear eye
protection and air
infitration mask
Cellulose Loose-Fill3.2 - 3.8 per inchGround recycled paper
products

Fire-retardant added to
reduce flammability
* Good coverage
* Works well in attics
* Less air movement
and reduction in
R-value than fiberglass
* Sound absorbing
* Higher recycled
content
*No itch associated
with fiberglass
*DIY friendly- requires blowing machine
* Allows for air and
moisture movement
without continuous,
near perfect air and
vapor barrier
*Tends to settle
reducing R-value
and leaving
uninsulated areas
at top of walls
* Loss of fire-retardant
performance with time
* Can draw moisture
and promote mold
* If wet, must be
replaced
Cellulose Damp Spray3.5 - 3.8 per inchGround recycled paper
products, similar to
loose-fill cellulose,
applied with small
quantity of water to
help it bind to wall
cavities to reduce
settling
* Good coverage
* Less settling than
loose-fill cellulose
* Non-flammable (with
added fire retardant)
* Many of same
issues as loose-fill
cellulose (see
above)
* Must allow
insualtion to dry
prior to covering
* Special installation
equipment required -
not DIY friendly
Rockwool Loose-fill

(Also known as mineral wool)
3.0 - 3.3 per inchSpun molten rock or
iron ore blast furnace
slag - made into long
fibers in a similar
process as fiberglass

(One time the most
common type of
insulation - replaced
by fiberglass)
* Similar advantages
as loose-fill fiberglass
(see above)
* Non-flamable - won't
melt or burn
* Produced from post
industrial recycled
waste products
* Tends to settle
* Very dense and
heavy
