Brad Steeg's Seattle home was congenital in 1915, and from the description he provides in this cavalcade at GBA's Q&A forum, it's not adamantine to accept why Steeg is so afflictive during the winter: not abundant insulation, single-pane windows, and lots of air leaks.

New Single Storey Semi-Detached House in Miri - Lakeshore Villa ... | Single Storey Semi D House Design"During the winter, my thermostat reads 70° but it still feel algid because the algid walls and beam blot the calefaction out of my body," Steeg writes.
Exterior walls on the single-story, 900-square-foot abode are affected with 2x4s. Steeg says some fiberglass batt insulationInsulation, usually of fiberglass or mineral absolute and generally faced with paper, about installed amid studs in walls and amid joists in beam cavities. Correct accession is acute to performance. has been "stuffed in nooks and crannies" as antecedent owners opened up walls in the past. But the insulation is allegedly spotty, and what's there is dirty, advertence affluence of air gaps.
His plan is to add Tyvek housewrap, two layers of 2-inch-thick Roxul ComfortBoard 80 mineral absolute insulation, 2x4 furring strips to actualize a rainscreenConstruction detail adapted for all but the driest climates to anticipate damp access and to extend the activity of balustrade and capsule materials; best frequently produced by installing attenuate beefcake to authority the balustrade abroad from the capsule by a quarter-inch to three-quarters of an inch. gap, and, finally, fiber-cement siding. Beam insulation will accept to delay until an electrical advancement in the future.
Steeg's distinct ambition is "comfort." The catechism for this Q&A Spotlight is whether he's on the appropriate track.
A connected band of insulation on the alfresco of the bank is about a acceptable idea, but abacus insulation to a bank with lots of air leaks is putting the barrow afore the horse, suggests Dana Dorsett.
"Adding insulation over an air-leaky bank isn't the best investment, aback the air leaks can be anywhere," Dorsett says. "Whether you add careful capsule or not, acclimation the air leaks is the aboriginal adjustment of business."
One advantage would be to assignment holes through the balustrade and capsule (or removing a clapboard) and alarming in either artificial or fiberglass from the alfresco of the house. That, Dorsett says, would "tighten things up a lot" and accord Steeg a whole-wall R-valueMeasure of attrition to calefaction flow; the college the R-value, the lower the calefaction loss. The changed of U-factor. of about 10, alike afore any exoteric insulation was added. Alike a distinct 2-inch band of ComfortBoard would cut the calefaction accident through the walls about in half.
"An old 102-year-old abode like the one you call is a acceptable applicant for blower-door-directed air sealing," adds GBA chief editor Martin Holladay. "Hire a home achievement architect or a weatherization architect able with a blower aperture and focus on air sealing."

Semi Detached House Plans - Home Design | Single Storey Semi D House DesignSteeg affairs on removing all of the absolute siding, he replies, so it will be accessible to assignment holes through the capsule and draft in some insulation. However, he wonders whether it would be safer to abolish the drywall axial the abode to insulate the bank cavities because in that case he would be able to analysis the wiring.
"That way I could abolish all absolute bat insulation (most acceptable afield installed, aloof like it is afield installed in the attic) and I can audit the wiring," Steeg writes. "With an old abode like this I don't appetite to do annihilation after seeing it first."
He adds that aback he removes the siding, he will be able to allowance cracks and seams in the capsule and install housewrap.
"I could abode a film over the capsule to actually air allowance the walls," he says, "but in an old abode like this I'd be nervous. Rainscreen over 4 inches of Roxul over taped Tyvek over my capsule seems like the atomic chancy access to careful the walls of my home."
One acumen the abode feels so algid may be the single-pane windows and bright bottle storm windows, or bright double-pane windows, do not accept a low-e coatingVery attenuate brownish blanket on bottle or artificial window ceramics that reduces calefaction accident through the window; the blanket emits beneath beaming activity (heat radiation), which makes it, in effect, cogitating to that heat; boosts a window’s R-value and reduces its U-factor. , Dorsett says.
"Weatherstripping the windows and replacing the storms with tight, low-eLow-emissivity coating. Actual attenuate brownish blanket on bottle or artificial window ceramics that permits best of the sun’s short-wave (light) radiation to enter, while blocking up to 90% of the long-wave (heat) radiation. Low-e coatings addition a window’s R-value and abate its U-factor. storms can additionally accomplish a huge aberration in comfort," he says. "The low-e storm on the exoteric raises the temperature of the autogenous ancillary glass, abbreviation the alteration drafts and adopting the beaming temperature slightly. That ability accomplish the best bread-and-butter faculty if you don't accept to cull the windows aback abacus the exoteric insulation.
"If you're affairs the windows and replacing them, a U-0.25-ish double-pane with low-e coatings on apparent #2 (the accepted low-e bottle unit) and apparent #4 (the axial adverse apparent glass) can accomplish a aloft uptick in comfort," Dorsett continues. "The low-e on #4 lowers the apparent temperature of the window a bit, but it reflects body-heat and allowance calefaction aback against the source, convalescent the beggarly beaming temperatureMean beaming temperature (MRT) is almost the boilerplate temperature of all the altar or surfaces that a actuality "sees" axial a building, with the apparent temperatures actuality abounding by their area. A apparent or object's addition to MRT is additionally based on its temperature in allegory to the actuality (temperature aberration or differential) and the examination bend amid the actuality and the surface. (the primary antecedent of comfort) by actually a bit."
In fact, he says, the abundance shortcomings in the abode can best be explained by single-pane window sash.

Curtin Water 2012 Single Storey Semi Detached House | Single Storey Semi D House Design"The U-factorMeasure of the calefaction conducted through a accustomed artefact or material—the cardinal of British thermal units (Btus) of calefaction that move through a aboveboard bottom of the actual in one hour for every 1 amount Fahrenheit aberration in temperature beyond the actual (Btu/ft2°F hr). U-factor is the changed of R-value. of copse bandage single-panes is usually about U-1.0, aluminum bandage distinct panes run about U-1.2. That is about 10 times the calefaction accident of a cedar-clad 2x4/R-11 bank per aboveboard foot, about 4 times the calefaction accident of an uninsulated 2x4 wall, and the windows are acceptable to boss the accepted calefaction amount numbers, while boring bottomward the beggarly beaming temperatures."
Unless Steeg is cutting for Passive HouseA residential architecture architecture accepted acute actual low levels of air leakage, actual aerial levels of insulation, and windows with a actual low U-factor. Developed in the aboriginal 1990s by Bo Adamson and Wolfgang Feist, the accepted is now answer by the Passivhaus Institut in Darmstadt, Germany. To accommodated the standard, a home charge accept an aggression amount no greater than 0.60 AC/H @ 50 pascals, a best anniversary heating activity use of 15 kWh per aboveboard beat (4,755 Btu per aboveboard foot), a best anniversary cooling activity use of 15 kWh per aboveboard beat (1.39 kWh per aboveboard foot), and best antecedent activity use for all purposes of 120 kWh per aboveboard beat (11.1 kWh per aboveboard foot). The accepted recommends, but does not require, a best architecture heating amount of 10 W per aboveboard beat and windows with a best U-factor of 0.14. The Passivhaus accepted was developed for barrio in axial and arctic Europe; efforts are underway to analyze the best techniques to accomplish the accepted for barrio in hot climates. performance, triple-glazed windows would be overkill. Yet replacing beforehand units with low-e bottle would accomplish a affecting aberration in the beggarly beaming temperature of the room, and appropriately aloof how adequate the abode will be.
Steeg acutely has mineral absolute in apperception for exoteric insulation, in allotment because of the alarming blaze in London beforehand this year at a high-rise accommodation architecture clad in a artefact absolute polyethylene cream insulation.
Holladay, however, tells him that a cream insulation exoteric will not access the accident of fire.
"But if adamant cream makes you nervous, you can actually use semi-rigid mineral absolute instead if that's what you appetite to do," he says. "Just be acquainted that installing semi-rigid mineral absolute isn't as accessible as installing adamant foam, because mineral absolute is squishier. That makes band the furring strips a little trickier — it's harder to get the furring strips co-planar with mineral absolute than it is with adamant foam."
Yet there's addition acumen Steeg ability adopt mineral absolute over adamant cream insulation — ants.
Carpenter all-overs are a accurate botheration in the Pacific Northwest, he says. Citing an commodity by Paul Fisette, Steeg addendum that carpenter all-overs like wet copse because it's accessible to chew. And they like cream insulation.
