One of the largest sources of vermiculite was a mine in Libby, Montana, which was closed in the early 1990s. This mine also contained asbestos, a known carcinogen and lung hazard, so much of the vermiculite insulation that was installed contains asbestos. 3 It typically had a black paper backing. The fibers are tan/brown, and the fibers look like sawdust. 4 Another insulation no longer commonly installed is urea formaldehyde, also known by the acronym UF or as UFFI (pronounced “you-fee”). It is found in buildings dating to the early 1980s but has seen little use since that time because of concerns over formaldehyde off-gassing.
Building height, or floor-to-floor height, can be estimated visually (or on photographs) against door heights. A door itself is typically 6′ 8′′ , but adding the frame brings it very close to 7′ . Heights can also be estimated relative to the height of a person—the average height of adults is 5′ 7′′ . 1 Water Temperature Folk Quantification Temperature Range Perception/Sensation Greater than 110 F 105–110 F 100–105 F 95–100 F 90–95 F 85–90 F 80–85 F 60–80 F 40–60 F Less than 40 F — — — — — — — — — — Steam appears Approximate limit of too hot to touch Hot Warm Neutral on skin Slightly cool Cool Cold Very cold (painful within 10 seconds) Feels ice cold (painful immediately) The dimensions of concrete masonry units (CMUs) can be used to estimate wall dimensions.
Insulation in these areas should be air sealed, to prevent moist interior air from reaching cold structural components on the cold side of the interior insulation. Insulation can be added to flat roofs. A variety of rigid foams are commonly used. 20). The pitch of this taper is generally required by code to be a minimum of 1∕4′′ per foot (1:48), although it is not unusual to find slopes as low as 1∕8′′ per foot (1:96) or as high as 1∕2′′ per foot (1:24) or higher. 12 The underestimation has come about because an average thickness of the roof insulation has been used to calculate the R-value.
