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
