INSULATION
SUPERINSULATING MEANS A MORE COMFORTABLE HOME!
Turn of the century row homes were not built with sustainability in mind when it comes to energy use. They have a host of problems when it comes to keeping them properly heated and cooled.
Even temperature throughout the home
-
Easy to heat and cool
-
Maintains temperature longer
-
Helps eliminate drafts
-
Minimizes having hot/cold rooms, walls, spots and drafts
Thermal bridges: the comfort thief in a home!
THERMAL BRIDGING INFRARED IMAGES I(I NEED TO GET THESE)
The goal: eliminate thermal bridging for a more comfortable home
Thermal bridges are junctions where a break in the continuous insulation of a building envelope allows heat loss. Another way to look at thermal bridging is when one material is more conductive that another, allowing heat to flow.
found at the junctions floor and wall,
-
wall and foundation,
-
wall and roof.
-
Framing
-
Thermal bridges can also be extensive at doors or windows.
Penetrations in the building for roof vents, bath vents, plumbing vents, electrical penetrations.
How True Turtle eliminates thermal bridging: THE CONCEPTS...PLACE THE 4 COCEPTS DRAWINGS IN THIS GALLERY
-
Insulating all six sides keeps heating (or cooling) in your home
-
Connecting insulation minimizes cold/hot areas
-
Continuous insulation for consistent R values everywhere
-
More insulation is better for high overall comfort
TRUE TURTLE RETROFIT DETAILS
Roof
Walls – frame
Walls - brick
Floors
Our deep energy retrofit work on rowhomes also encompasses new additions. For these new construction walls, our detailing is very different than our retrofit work.
Our new construction superinsulation provides
* continuous insulation
* connected insulation
* and almost twice the code required amounts of insulation!
CHECK IT OUT!
Roof - R78 that's nearly twice code requirement
Frame walls - R32 that's over twice code
Basement walls - R21 that's nearly twice code
Subslab - R8 Code doesn't require subslab insulation, so we are in essence going above and beyond the call of duty by even having insulation under the slab.

NEW CONSTRUCTION SUPERINSULATION
GREEN INSULATION OPTIONS WE LOVE!
CELLULOSE
Why cellulose is great
Significant R value per inch...3.7 R/in
As cheap as fiberglass
Great for sound control
Great at preventing air movement in cavities
High vapor permeability
Treated with borate for fire and pest resistance
Borate is non-toxic to humans
Low global warming potential
Up to 85% recycled content
Cellulose limitations
Cannot get wet
Installation consistency is key
POLYISO
Why polyiso is great
It’s an excellent continuous insulation
High R value at 6.5 R/in
Blowing agent is water - no CFC’s or HCFC’s means low global warming potential
More fire retardant than other board insulations
It’s vapor impermeability can be useful
Polyiso limitations
It’s not cheap
It cannot get wet
R value drops when cold
EPS (Expanded Polystyrene)
Why EPS insulation is great
Good R value per inch - 3.6-4.2 R/in depending on density
Cheap!
Vapor permeable
Flame retardant without HBCD
Water blown - no CFC’s or HCFC’s = low global warming potential
Does not absorb moisture socan be used in wet locations
Can be structural
Resistant to mold
Can be recycled and made from recycled components
EPS limitations
Fragile
Ants love it
Mineral Wool
Why mineral wool is great
~4 R/in
Great sound attenuation
Can get wet and be used underground
Highly resistant to pests
High recycled content
Zero global warming potential
Mineral wool limitations
Expensive! Even more costly than polyiso
It’s more difficult to install than poly iso
Potential formaldehyde problems limit its use to exterior applications
