Window And Window Installation

Question 1

What considerations usually determine the type of window chosen?

Answer 1

Cost, looks and how maintenance free the owner wants the window

Question 2

What type of window could be used if your customer wanted wood inside, but wanted the window to be maintenance-free outside?

Answer 2

Cladding (covering) the exterior wood windows with aluminum or vinyl is a good compromise for those who want the look and feel of wood on the inside, but not the maintenance of wood on the outside.

Question 3

What are the four material types used for Windows?

Answer 3

Vinyl (PVC)
Wood
Aluminum
Aluminum/Vinyl Clad wood

Question 4

Aluminum is a rigid, strong material that allows relatively small frames to hold large glass panels. The hollow frame members are often filled with rigid foam insulation to increase their energy efficiency. T or F

Answer 4

T

Question 5

Describe a casement window?

Answer 5

Casement windows are hinged on the side and swing out to open.

Question 6

Explain the difference between double-hung and singe-hung windows.

Answer 6

Double-hung means that both sections slide to open, while single-hung means that only the bottom section slides open.

Question 7

Fixed or picture windows do not open to provide ventilation. T or F

Answer 7

T

Question 8

Explain the difference between bay and bow windows.

Answer 8

A bay window is a combination of a large central window and two angled side windows.

A bow window is in the shape of an arch made with several sections all the same size.

Question 9

What is glazing?

Answer 9

Glazing is the term used to refer to the glass panels inside the frame used to make the windows.

Question 10

Glass has little insulating value on its own, how do manufacturers to help reduce heat loss?

Answer 10

Special coatings (Low-E) and seal inert gases like argon in between layers of glass

Modern windows typically have at least two layers of glass, with a 10 to 12 mm space between them to help increase the insulating value.

Question 11

When installing the glazing (sealed unit) in the sash how is it supported?

Answer 11

By neoprene pads called setting blocks which are places at the quarter points along the bottom of the sash. They support and allow the glazing to expand and contract.

Question 12

The outside window in a bedroom must be at least ___ square metres with no dimension less than 380 mm.

Answer 12

0.35 m squared

Question 13

Where a bedroom window opens into a window-well, a clearance of not less than ___ shall be provided in front of the window.

Answer 13

550 mm (22”)

Question 14

When are windows usually installed in residential construction?

Answer 14

At the conclusion of the framing stage in residential construction.

Question 15

How much clearance should be around the window in the opening for insulation?

Answer 15

10 mm clearance on all sides

Question 16

What is the purpose of the small packing pads found inside the window when you open it and when should they be removed?

Answer 16

Do NOT open windows and remove the small packing pads that are inside until after the unit is completely installed. They help keep the unit square and maintain proper clearances during installation.

Question 17

Are any additional shims required for talk, wide or multiple unit windows?

Answer 17

Shim at the dividing rails and ensure that the width or height is the same at these points.

Question 18

If you use expanding foam to insulate around windows, what type should you use?

Answer 18

The type recommended by the window manufacturer that will exert less pressure as it expands and does not bulge the frame.

Question 19

What is the purpose of gluing the mitres as they are assembled?

Answer 19

Helps keep it tight and lock it in place so it resists opening due to material shrinkage and building movement.

Question 20

1) provide protection from the weather.
2) allow ventilation
