A
Arch Window
Arched windows feature a curved, semi-circular design and are often installed above doors or standard windows to bring in additional natural light.
There are two common ways to cover arched windows:
Custom-fit solutions such as wood blinds or honeycomb/cellular shades can be made to match the exact curve of the window for an inside mount. A template of the window shape is typically required.
Outside-mounted treatments can also be used, provided the blind or shade extends beyond the widest and tallest points of the arch to ensure full coverage.
B
Bathroom Window Treatments
Bathroom blinds and shades must withstand moisture and heat. The best options include:
Faux wood blinds, which resist warping better than real wood
Aluminum (mini) blinds, known for durability and easy cleaning
Top-down/bottom-up shades, which allow light in from the top while maintaining privacy below
Bottom Rail
The bottom rail is the reinforced horizontal bar at the base of a blind or shade. It anchors the lift cords and ladders and is finished to match the material of the window covering.
Box Bracket
Box brackets are mounting hardware used for horizontal blinds and shades. They can be installed inside or outside the window frame, allowing the headrail to snap securely into place.
Braided Ladder
A braided ladder is the vertical support system that holds slats in position. Made from durable polyester, it enables smooth tilting and lifting of horizontal blinds.
C
Center Support Bracket
Used for wide or heavy blinds, center support brackets provide extra stability and prevent sagging by supporting the middle of the headrail.
Clearance
Clearance refers to the depth available inside the window frame for an inside-mounted blind or shade. Horizontal blinds generally require more depth than fabric shades.
Cloth Tape
Cloth tapes are decorative fabric strips that cover ladder cords on horizontal blinds. They enhance privacy by concealing route holes and add a customized design element.
Continuous Cord Loop
A continuous cord loop system allows blinds or shades to raise and lower evenly with a single looping cord. This design improves child safety and is ideal for large or heavy window coverings.
Control Length
Control length is the measurement of the lift and tilt mechanisms. Typically, it equals about half the total height of the window covering.
Cord Lock
The cord lock is the internal mechanism that holds a blind or shade in place once it has been raised or lowered.
Cord Tilt
A cord tilt system lets you adjust the angle of the slats by pulling the cord to open or close them.
Cutout
A cutout is a customized notch in a window covering designed to clear obstacles such as door handles, window cranks, or molding.
E
End Cap
End caps cover the exposed ends of the headrail and bottom rail, creating a clean, finished look that matches the colour of the window treatment.
Extension Brackets
Extension brackets provide additional depth for outside-mounted blinds when the window frame protrudes outward.
F
Fully Recessed
A fully recessed window covering is installed completely inside the window frame, sitting flush without extending into the room.
H
Headrail
The headrail is the top component of a blind or shade. It houses the operating mechanisms and supports the ladders that control lifting and tilting.
Hold Down Brackets
Hold down brackets secure the bottom rail to prevent movement. They’re commonly used on door blinds or outside-mounted treatments.
I
Inside Mount
An inside mount means the window covering is installed within the window frame for a streamlined, built-in appearance.
L
L-Brackets
L-brackets are mounting brackets that add extra projection when standard outside-mount hardware doesn’t provide enough clearance.
Ladder Grommets
Ladder grommets are metal fasteners attached to the bottom rail that help align ladders and keep the blind level.
Lift Cord
The lift cord raises and lowers the blind or shade and is usually positioned on one side of the window covering.
Loop Ladder
Loop ladders are used in routeless wood and faux wood blinds. They allow cords to run through loops rather than holes, improving privacy.
M
Multiple Blinds on One Headrail
For extra-wide windows, two or three blinds can be mounted on a single headrail. Each unit operates independently while maintaining a unified look.
N
No Holes Privacy
This feature removes traditional route holes, reducing light leakage and improving privacy by routing cords through notches instead.
O
Outside Mount
An outside mount installs the window covering on the wall or trim above the window, often used to maximize coverage.
P
Projection
Projection measures how far the mounting hardware extends from the wall, ensuring the blind clears window trim or handles.
R
Return
Returns cover the exposed sides of an outside-mounted headrail, attaching to the valance for a polished finish.
Return L-Bracket
This bracket secures the return to the valance, hiding gaps at the sides of the window covering.
Roman Fold
Roman folds create a soft, layered appearance as the shade stacks evenly when raised.
Route Hole
Route holes are small openings in slats that allow lift cords to pass through in traditional blinds.
Routeless
Routeless blinds eliminate route holes, improving light control and allowing individual slats to be removed for cleaning.
S
Stop Ball
The stop ball gathers lift cords together and prevents them from pulling through the headrail.
T
Tassel
A tassel is a decorative accent attached to the ends of lift or tilt cords.
V
Valance
A valance is a decorative top piece that conceals the headrail and mounting hardware.
Valance Clip
Valance clips secure the valance to the headrail when it isn’t factory-installed.
W
Wand Tilter
A wand tilter is a rigid rod used to rotate slats open or closed by twisting it in either direction.

Arch Windows (Common in Vancouver Homes)
Arched windows are often found in Vancouver heritage homes and custom builds, where architectural details are a focal point. These curved windows allow more natural light and add visual interest.
Covering arched windows typically involves:
Custom-fit blinds or cellular shades, measured precisely for an inside mount
Outside-mounted window treatments, extended beyond the arch to ensure full coverage
Bathroom Window Treatments (Moisture-Resistant Options)
Due to Vancouver’s coastal climate, bathroom window coverings must be resistant to moisture and humidity.
Popular choices in Vancouver homes include:
Faux wood blinds, which resist warping
Aluminum mini blinds, known for durability
Top-down/bottom-up shades, ideal for privacy while allowing natural light
Inside Mount vs. Outside Mount (Vancouver Condos & Homes)
Inside mount blinds fit neatly within the window frame and are popular in modern Vancouver condos.
Outside mount blinds are often used in older homes to maximize light coverage and conceal uneven trim.
Energy Efficiency & Light Control in Canadian Homes
Features such as routeless blinds, cellular shades, and fully recessed installations help Vancouver homeowners improve insulation and reduce heat loss—especially during colder seasons.
