Questions with Guaranteed Pass
Solutions 2025-2026 Updated.
Abrasion Resistance: - Answer The ability of a material to withstand abrasion without
appreciative erosion.
Absorption: - Answer The process of drawing fluid or gas into a porous material, such as a
sponge soaking up water.
Abuse Coverings and Finishes: - Answer Jackets, mastics, or films used to protect insulation
from mechanical and personnel abuse.
Added R-value: - Answer Thermal resistance added to a construction element by insulation.
Adhesive: - Answer A substance used to bond materials by surface attachment.
Aerogel: - Answer A homogeneous, low-density solid-state material derived from a gel, in
which the liquid component of the gel has been replaced with a gas.
Air Space: - Answer The area between insulation facing and the interior of exterior wall
coverings. Normally a 1-inch air gap.
Aluminum Foil: - Answer Thin sheet of rolled aluminum (0.15 mm thick and under).
Anti-Abrasive Coating: - Answer Cushioning material applied where insulation contacts pipe,
duct, vessel, or adjacent insulation to prevent eroding of either or both.
Asbestos: - Answer The generic name for those silicate minerals that cleave naturally into
fibers, the three important forms being chrysotile (white), crocidolite (blue), and amosite.
Bands: - Answer Strapping used to fasten insulation and/or jacketing in place.
, Blanket Insulation, Metal Mesh: - Answer Blanket insulation covered by flexible metal-mesh
facings attached on one or both sides.
Blanket Insulation: - Answer Insulation of flexible type, formed into sheets or rolls, usually
with a vapor barrier on side and with or without a container sheet on the other side.
Block Insulation: - Answer Semi-rigid insulation formed into sections, rectangular both in
plan and cross section, usually 90-120 cm (3 - 4 ft) long, 15-60 cm wide (0.5 - 2 ft), and 2.5-15
cm (1-6 in) thick.
Blocking: - Answer A material used to retain the insulation in place in open areas.
Board Insulation: - Answer Semi-rigid insulation formed into sections, rectangular both in
plan and cross section, usually more than 120 cm (4 ft) long, 60-75 cm (2 - 2.5 ft) wide, and up
to 10 cm (4 in )thick.
Breather Coating: - Answer A weather barrier coating designed to prevent water (rain, snow,
sleet, spillage, wash water, etc.) from entering the insulation system, while still allowing the
escape of small quantities of water vapor resulting from heat applied to the moisture entrapped
in the insulation.
Butt Joints (insulation): - Answer The end joints of pipe insulation.
Butt Strip: - Answer Strips of similar jacket material applied around pipe insulation butt
joints.
Calcium Silicate Insulation: - Answer Insulation composed principally of hydrous calcium
silicate, and which usually contains reinforcing fibers.
Canvas: - Answer A closely woven fabric of cotton, flax, hemp, or jute characterized by
strength and firmness.
Cavity: - Answer Empty space between studs/joists in which insulation is placed.
Cellular Elastomeric Insulation: - Answer Insulation composed principally of natural or
