1

Two sheets of glass with an air space between, to insulate against the passage of heat or sound. Also called double glazing.

insulating glass

2

Soil that is easily crumbled or reduced to powder.

friable

3

The hard fibrous substance lying beneath the pith and bark of trees.

wood

4

A groove cut into a member to receive another member.

rabbet

5

The work of installing glass in a frame.

glazing

6

The interior trough formed by the intersection of two sloping roof surfaces.

valley

7

A substance that inhibits the development and action of fungi, borers, and insects that deteriorate wood

preservative

8

Material used to prevent the passage of liquid across a joint or opening.

sealant

9

American Society for Testing and Methods.

ASTM

10

Steel having a carbon content over 0.5 percent. In general, increased carbon content increases strength and hardness, but decreases ductility.

high-carbon steel

11

Removing and/or adding earth in order to bring the ground surface to a specified elevation or profile. Also called earthwork.

grading

12

Glass which has four or more layers of glass laminated to three or more layers of plastic, used where strong impacts may occur.

bulletproof glass

13

The upright or vertical edge of a door or window.

stile

14

A roofing material applied in several layers to create a built-up composition roof.

asphalt saturated felt

15

A door that moves horizontally, either on a track in the floor or from rollers at the head.

sliding door

16

Roofing made up of plies of saturated roofing felts alternated with layers of pitch or hot asphalt cement and surfaced with gravel or a cap sheet.

17

A permanently plastic waterproof adhesive material used in sealing joints.

mastic

18

A small hole near the bottom of a retaining wall, usually backfilled with gravel, to allow water to drain to the outside of the wall and thus avoid hydrostatic pressure against the wall.

weep hole

19

The driving device of a hydraulic elevator, which is powered by liquid under pressure within a cylinder. Also referred to as a ram.

plunger

20

The most widely used system for classifying soils. In this system, the soils are primarily classed as coarse-grained (gravels and sands), fine-grained (silts and clays), and highly organic.

Unified Soil Classification System

A vertical support for a handrail

baluster

25

The ease with which a metal can be shaped by hammering or by machine.

malleability

26

A rounded exposed edge, such as a tile or wood trim piece.

bullnose

27

A ratio used to determine the bearing capacity of a soil, based on a standard test.

California bearing ratio (CBR)

28

The heart center of a log.

pith

29

A joint formed when a concrete surface hardens before the next batch of concrete is placed against it.

cold joint

30

A vertical shaft that accommodates one or more elevators, conveyors, or dumbwaiters.
