Concrete Joints

A control joint is an intentional cut into the concrete, normally ¼th the total thickness. The control joints purpose is to prevent cracking beyond the intentional cut.

Isolation joints are used to relieve flexural stresses due to vertical movement of slab-on-grade applications that adjoin fixed foundation elements; the column is being isolated from the slab.

Front End Loader

A loader is an engineering vehicle that is primarily used to load material into or onto another type of machinery.

A backhoe digs holes and a bulldozer pushes earth around.

Gypsum Board

Gypsum board is a common building material typically made of a layer of gypsum plaster pressed between two thick sheets of paper, then kiln dried.

Heat Pump

Heat pump air handler units have a back-up source of heat inside them. Most heat pump air handler units utilize electric resistance heating for back-up heat but there are some that utilize gas for back-up heating.

The compressor/condenser extracts heat from the outside air and runs it through refrigerant lines to either heat or cool the air. It can take in air as cold as 32 degrees.

An advantage is that is has a rapid response time and a disadvantage is that it’s difficult to zone.

Insulation

Batt/Blanket Insulation

Insulation is a material with a low thermal conductivity that is included in a building assembly for the purpose of reducing heat flow through the assembly.

Insulation

Foamed Insulation
