The Hardiewrap in the picture is helping control the infiltration of air into the
The soffit vent in the picture allows air to transfer into the attic to help ventilate
to help with moisture control. This type of vent is installed on all the flat parts of
the soffit. In the gabled ends the soffit is solid.
The ridge vent ventilates the hot air out of the
attic that the soffit vents let in. The vent itself
is under the shingle on top.
The gable vent lets both hot air in and out of the attic space. The
gable vent plays a vital role in the ventilation of the attic. Sometimes
they are fake vents but in this case their real.
The wind turbine also releases hot air from the attic.

them are a perfect circle . They are also referred to as round arches that
were brought about by the Byzantine people.
Brick Arch # 2
The brick arch in this picture is an example of a gothic arch. The arch
goes up to the top and meets at a point which makes it very distinctable.
Brick Arch # 3 with keystone
The two arches in this picture were both capped off with a keystone in
the center of them.
Centering is the temporary supports that hold an arch
together while the mortar sets up and hardens.
Brick Bond # 1
This is a common bond where the brick sit on top of the
others by about 1/3 the size of a brick.
Brick Bond # 2
In this picture, there is an example of running bond in the
brickwork on the fireplace. The running bond is easy to
notice because the brick are staggered on top of each other.
Front End Loader
A front end loader is used for multiple reasons in the excavating of the land. It can move dirt
from spot to spot , and can be used to level the land off. The front end loader has a much wider
bucket than the backhoe.
An interior finish panel that has Gypsum in between two pieces of paper backing.
Gypsum board takes up a large majority of the finish construction in a house.
Advantage: The heat pump can increase the heating by a factor of 3.
Disadvantage: The duct work that the pump supplies heat to can leak and lose a descent amount
of the heat.
The compressor supplies the air to the duct unit inside the house.
Air Handling Unit
The air handling unit takes in the air from the exterior of the house and transfers it to the inside.
The batt insulation is used to help control the air movement through the walls. The
batts come in 8 feet length sections and also rolls.
Loose Fill Insulation
Loose Fill Insulation is more commonly used in ceilings to help prevent the hot air in the attic
from entering the house.
Foamed Insulation can be used in any part of the house, and really helps with keeping air in or
out because of no cracks of any kind.
Rigid Board Insulation
The rigid board insulation is primarily used on the exterior of the house, and can take place of the sheathing .
In this picture I am in an addition and the insulation is on the exterior of the old house.

Oriented Strand Board
A wood panel that contains long strands of wood fibers glued together to be used as some type of sheathing. It
is manufactured by pressing strands of wood together along with glue. It is a nonveneered wood panel product
because it is made of strands of wood instead of multiple veneers.
A lavatory is a bathroom sink or some other type of pedestal sink that can be used for multiple ways of

A gutter catches the rain as it comes off the roof to transport it to the ground through a downspout. Without
the gutters the soffit or facial would not last anytime because of getting wet from rain water.
The downspout transfers the water from the gutter to the ground or some kind of catch tank. Usually at the
bottom of the downspout there is some type of PVC pipe to continue with the removal of water.
A splashblock is usually located over an entrance or exit of a building to slow the drainage of water. In this case
the splashblock was applied where the water would not go right down the valley over the top of the gutter.
The underlayment protects the sheathing until the finish roof is installed. It is also a great backup in case any
water ever seeps through the shingles on top. In this picture the tar paper is protecting the sheathing until the
rest of the shingles are put on.
A layer of building material that prevents the passage of water into the building. It is extremely important to
keep water vapor out of the walls. It is usually put on the warm in winter side of the building.
Waterproofing is applied to the exterior of the foundation to keep moisture out. The
waterproofing in this picture is liquid applied. This example is easier applied to the foundation.
