Lift cords for all between glass venetian blinds must remain inside the sealed window unit.
Lift cords should be accessible only to properly trained and authorized personnel.
Differences Between 1" and 5/8" Blinds
When deciding between 1" and 5/8" blinds, please note:
1" blind is less expensive
1" blind requires a minimum airspace of 1-1/8"
5/8" blind requires a minimum airspace of only 3/4"
THICKNESS OF SLAT
1" blind uses a more resilient slat that is .008" thick
5/8" blind uses a slat that is .006" thick (Once the blinds are safely installed within the window, resiliency is not an issue as the blinds are protected by the glazing materials in your window system.)
Due to the thinner slats, the 5/8" blind is easier to look through in the open position
1" blinds will exhibit slightly better shading coefficient characteristics
Some manufacturers will refer to their 15mm blind as a NOMINAL 1/2" BLIND. A 15mm slat (which is the narrowest slat available in the world) is .591" wide. Nobody manufactures a blind narrower than our 625 Series Blind.
