SUB Building – Air Sealing and Insulation Measure
Maintenance workers prepare for
insulation job.
Existing R-19 fiber glass attic insulation
placed between ceiling joists on 24 inch
centers.
New R-30 fiberglass bats installed on
top of existing R-19 insulation.
SUB Building attic: 56’ x 36’ (2016 sq. ft.). Existing insulation consists of R-19 fiberglass bats between ceiling
joists on 24” inch centers.
Materials provided: 28 bales of R-30 fiber glass insulation 24” x 48” bats (80 sq ft ea. bale), 3 tyvek suits, dusk
masks, dust particle respirators and 12 tubes of siliconized, paintable caulking and caulking guns.

Alaska Building Science Network – Village End Use Energy Efficiency Program – ’07-’08 Final Report NW/SW Region – Chignik Lake
Work Completed:
1. Removed stored items from attic area to avoid compressing batt insulation.
2. Installed one layer of new R-30 fiberglass bats perpendicular, over the top of existing layer of R19 fiberglass
insulation. This will add to thermal retention by reducing air movement through seams of existing insulation.
3. Attic insulation increased from R-19 to R-49.
The following section details insulation measure procedures for adding fiberglass bats. This is excerpt from
ABSN’s: Attic Insulation and Air Sealing Procedure and Release Form which is read and signed by each village
maint staff person working with fiberglass bat insulation measures.
_________________________________________________________________________________________
Safety Protocols:
ABSN provides the following safety equipment which shall be worn by each worker involved in installing attic
insulation:
Respirator face masks with nose/mouth, flexible rubber seal and P-100 particle filter cartridges.
Wrap-around safety goggles for full eye protection from exposure to fiberglass fibers.
Tyvek suits with hoods.
Gloves (cloth and rubber).
Quality Control Rules of Thumb:
Spray foam, and/or caulking for air-seal around electrical boxes, wiring and other ceiling penetrations will
be done wherever possible - before installing insulation. Appropriate color, quantity and placement of
caulking will be applied to result in a professional seal and finish.
Insulation will make light contact with ceiling (not roof).
A 2" - 3" gap, of air space will be allowed between insulation and roof - especially at eve for proper
ventilation and cooling of roof.
Insulation will not be compressed, and will be worked to allow full expansion of its loft.
There will be no gaps between bats of insulation or between insulation and framing members.
There will be no surface level changes among same R-value bats of insulation,
Insulation will be cut and worked to fit snugly around framing members.
Insulation will be cut and worked to fit around electrical wiring, cable and vacuum lines - and to make light
contact with ceiling sheet rock and vapor barrier.
Insulation level will be continuous across attic access hatch. This will be accomplished by taping bats of
insulation on the hatch-cover without compressing insulation.
Access hatches will be caulked shut for air sealing.
These rules of thumb are important, because a sloppy insulation job that results in 3% voids or gaps
between fiberglass bats looses 30% of its insulation capacity! For example R -30 can end up R-20 or less if
care is not taken for quality installation.

ADDITIONAL CONSULTING
In addition to completing the for-mentioned lighting upgrades and additional measures, Dan Lung with consulted
the Lake and Peninsula School District on additional measures they could take to reduce their energy loads. The
following recommendations were made:
Recommendations for further savings (not covered by this project)
Old boys and girls bathrooms:
Each bathroom has three, T-5, 2-lamp fixtures (at 115 watts each) that were installed during the school remodeling.
Since T-5 fixtures are designed for lighting spaces with high ceilings (greater than 8ft), I took one fixture off -line in
each bathroom as a short term strategy to reduce wattage due to over-lighting. With that, I recommend actually
removing those T-5 fixtures and replacing with two standard 2-lamp T-8 fixtures with 25 watt lamps. Those run at
46 watts each and will provide more than adequate light levels for those spaces. Long-term savings will add up, ,
especially since those lights are on for approx 10-12 hrs per day. (please see photos under school above).
New boys and girls bathrooms:
Each bathroom has two, T-5, 2-lamp fixtures (at 115 watts each) currently installed in the shower spaces. I
recommend replacing those with two moisture proof 2 -lamp, T-8 fixtures with 32 watt T-8 lamps. These are the
same style fixtures currently installed in the old bathroom shower with sealed plastic covers (see photos under
school above). Similarly, these lights are on 10-12 hrs per day which is costly.
Student store/storage (old side):
replace existing T-5 fixtures (x3) with a 2 or 3-lamp T-8 fixture.
new janitor and sports equip storage (near gym):
replace existing T-5 fixtures (1 ea.) with a 2-lamp T-8 fixture.
In summary, the T-5 fixtures in the spaces mentioned above are severely over-lighting those spaces and are
costing more than what is necessary especially considering the number of hours these lights are on during the day.
