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.

2. BATTS & BLANKETS
TypeR-valueMade From &
Characteristics
AdvantagesDisadvantages
Fiberglass Batt or
Blanket
2.2 - 4.3 per inchSoft, wool-like
material - usually
pink, yellow or
white
* Inexpensive
* Non-flammable but
will melt
* Readily available
* DIY friendly? (If you
don't mind the itch)
* R-value reduced by
compression, air
currents and dust and
dirt accumulation
* If wet, must be
replaced
* Irritating to work with
- use eye protection
and air filtration mask
Rockwool Batt or
Blanket
3.0 - 3.3 per inchSpun molten rock
or iron ore blast
furnace slag
* Non-flammable - won't
melt or burn
* Produced from post industrial recycled
waste products
* DIY friendly
* Faces same issues
as fiberglass if not
installed carefully -
compression
reduces R-value, gaps
and voids allow air
flow and moisture
* If wet, must be
replaced
Cotton Batt or
Blanket
3.7 per inchPrimarily made
from recycled
cotton and
polyester mill
scraps
* Performs similar to
fiberglass
* Higher recycled
content
* DIY friendly
* Fibers don't cause
itchiness that
fiberglass does
* 15 - 20% more
expensive than
fiberglass
* Faces same issues
as fiberglass if not
installed carefully -
compression reduces
R-value, gaps and
voids allow air flow
and moisture
* Requires vapor
retarder or barrier
* Difficult to cut
* If wet, must be
replaced
RAYCORE STRUCTURAL PANEL INSULATION (SIP)
TypeR-valueMade From &
Characteristics
AdvantagesDisadvantages
Polyurethane Foam7 - 8 per inchDow 2-part chemical
(byproduct of
petroleum) mixed
and injected with
blowing agent to
form small air
pockets and molded
to form insualtion
panel
* Highest R-value
* Dense - resists
compression, impact,
or deformation
* Superior strength
* Provides air barrier
* Good acoustical
qualities
* Low permeability
* No moisture retention,
causing rot or mold
* Can withstand
flooding
* Class 1 fire-rated
*More expensive than
fiberglass or polystyrene
but good return on
investment with a
lifetime of energy
savings
* Can somewhat
degrade if long-term exposure to sunlight
(Construction
practices do not
lend to this being a
problem)
