( 2 glz .vinyl 3/4- air space •.Ld 'g dr . 35 .0 ft2 )
( 2glaze mt l. . insul w/full. 1.ight 19 .0 ft2 )
Windows are installed as shown on the approved plans . The rough
opening around windows and doors is caulked/sealed .
Exhaust fans , spot ventilation:
Bathroom fans are 50 CFM , kitchen fans are 100 CFM . Fan ducting
has minimal bends and terminates outside of the building .
The whole house exhaust fan is between: 100 .0 and 140 .0 C:FM .
INSULATION INSPECTION
Wall insulation :
( R19 ADV Lap Wood 1705 .0 ft2 )
Insulation fills all exterior wall cavities . It is not compressed
and is cut to fit around wires , pipes , and outlet boxes . Recessed
fixtures in exterior walls have at least L:._ 5 insulation behind
them .
Vaulted ceiling :
( R30 batt. Vault vented 2x1/ 24oc 370 .0 ft2 )
Insulation is installed to the manufacturer 's recommended density
and coverage without compression .
Vapor retarder : 1 .0 perm or less vapor retarder ( e .g . poly , kraft
paper , perm rated paint ) is installed on the warm side of
insulation in floors , ceilings and walls .
A 0 .5 perm vapor barrier is installed on all vaulted ceilings .
Recessed lights :
Any recessed light fixtures in the thermal envelope are certified
under ASTM E-283 and labeled showing compliance , or are sealed
around the exterior to be air tight .
FINAL INSPECTION
Crawl space moi sture barrier :
A six mu , black po.lyethelene ground cover is installed on
crawl:= pac'e tloo'r
F1.00r Insulation :
( R30 0 vent..:d ;Joie>t. 16oc 56 .0 ft2..)
Insulation is supported in a permanent manner without compression .
Crawlspace ventilation:

Pipe .insulation :
All water pipes in unheated spaces are insulated to ,t--'
Hot water :
Electric water heater labeled as meeting ASHRAE Standard 90A--1980
or 1987 NAECA . Tank has R---10 non-compressible pad underneath if
located over slab or in unconditioned space . Shower heads allow a
maximum flow rate of 3 .0 gallons per minute .
Doors:
(Metal. Insul , w/ Raised Panel 21 .0 ft2 )
( Metal R-5 base case 19 .0 ft2 )
Weatherstripping , t.hreshhold , and doorsweep are properly adjusted
and seal well .
Ceiling:
( R38 blown Attic STD baffled 983 .0 ft2 )
insulation is installed to the manufacturer 's recommended density
and coverage . Attic access doors are insulated and
weat.herstr ipped .
Heating system:
unknown/ unknown
The heating system does not exceed: 69647 BTUs .
Ventilation:
The ventilation system has been checked for proper operation . If
designed for intermittent operation , the system is controlled
automatically by a time-of-day timer set to run for a minumum of
eight hours per day . If designed for continuous operation , the
system is directly wired to a dedicated circuit in the electrical
panel .
Make-up air :
A duct provides fresh air directly into the return air plenum of
the central forced air heating system . The duct is .insulated to R4
if it runs through heated space . A motor-operated damper ,, located
within 36 inches of the air handler , prevents air from entering
the plenum when ventilation is not called for . A clock timer
operates the designated whole-house exhaust •fan., turns on the HVAC
air handler , and opens the mechanical fresh air duct damper
whenever ventilation is needed .
Make-up air :
The outdoor intake duct is equipped with a damper that limits flow
to 140 .0 CFM under normal operating conditions .
Fireplace/Woodstove:
Combustion air is ducted directly into the firebox . Duct has a
cross sectional area of at least 6 square inches and a readily

FILE : C : \WATTDATA\LD1309 .WS HOUSE ID : LD1309
accessible operable damper . Doors are installed and fit tightly .
All gas or oil combustion appliances ( except stoves and clothes
dryer ) have outside combustion air ducted directly to the
appliance . All stoves have an exhaust fan directly over them .
Combustion Exhaust :
Al ].. combustion exhausts are separated by minimum 3 ' vertically <:1
10 ' horizontally .
Radon monitor :
Radon monitor supplied to residents .
