Roller blind, Roman Blind or Venetian Blind; they are all blinds and they will all do the same kind of thing which is to block the light and to provide privacy. There are however subtle difference in the way each of these products function.
Stack size when the blind is up
Projection of the blind
Light Gaps around the edges
Ease of operation
Flexibility for privacy control
The purpose of this section is to help you understand these difference and for you to choose the style of blind not just because of price but because of function too.
All the window blinds that we sell on line, operate in a vertical or up/down motion. The stack size is the size of blind when it is in the up position.
Stack size is important to understand because this may influence where a blind is fitted and the size that you request. There is no point for instance putting a Roman Blind in a doorway reveal that has 2100mm height because it will reduce the door clearance down to around 1770mm meaning you will need to duck to get through the door. Instead because you now are aware of stack height, you would probably put the blind above the doorway.
A roller blind will provide a fairly consistent stack at of between 80mm and 90mm.
An Aluminium venetian blind will vary because each horizontal slat adds to the stack height. A 2.0m high aluminum venetian blind will have a stack or around 115mm.
A 50mm Vision wood venetian blind and 49mm Cedar Venetian blind have thicker slats than aluminium therefore they will have a bigger stack for the same height blind. With similar slat sizes, visionwood venetian blinds and cedar blinds will have approximately the same stack height. For example on a 2m high cedar venetian blind will have an approximate stack of 250mm. (Add or subtract 9mm for every 100mm change to this example height height)
A 63mm wide Visionwood blind has less slats than the same height 50mm Visionwood blind, therefore, a 63mm Visionwood blind will have a small stack height than the 50mm venetian blind.
Roman Blinds fold up from the bottom in horizontal panels. Roman Blinds have a fairly consistent stack height of around 330mm.
When a window blind is installed, it will project out from the wall by a certain distance. The amount a blind projects out at the top may be different to how it projects out at the bottom when it is fully down.
Projection is important because there may be obstacles like door handles or railing in the way that may impact the function of the blind.
A roller blind with a normal roll (NR) setup (as per the drawing above where the fabric rolls back toward the window) will project out approximately 80mm if it is face fitted to a wall or window frame. At the bottom, the blind will project out approximately 20-30mm.
A roller blind with a reverse roll (RR) setup (as per the drawing above where the fabric rolls away from the window and off the front of the blind) will project out approximately 90mm if it is face. (The base bar will add to the overall projection). At the bottom, it will project out approximately 80mm.
Light gaps are caused because the window blind cannot sit tightly within a window. None of the blinds that we offer on-line with provide you with a 100% light block. If you are after a 100% light block solution we can offer this however, we will need to call us as the product is a little too complex for on-line sales.
Roller blind gaps will depend on how the blind is rolled (ie back roll towards the window or front roll away from the window).
A front rolled blind will have a bigger light gap than a back roll blind. Best light block for a roller blind is achieved by installing the blind inside the window reveal and rolling the blind back towards the window (NR).
A roller blind will also have a gap of approximately 15-20mm between the edge of the fabric and the outer most edge of the brackets at the top of the blind. For example if you order a roller blind that is 1200mm wide, the fabric will be approximately 30-35mm narrower ie 1165-1170mm wide.
This will mean that if you set a roller blind inside a window reveal it will have a gap of approximately 15-20mm on the edge. Most of the time however, the window frame is wider than the fabric gap serves to minimises the impact of the gap.
Roller blinds are operated by a continuous chain that is set to the left or right of the blind. They can either move up or down. The bigger the blind the heavier it is to operate. In the standard and Deluxe range we use springs to take the weight off the blind so it is easier to operate.
Other than fabric choice, a blind can either be up or down, open or closed.
Roller blinds and roman blinds can only go up or down.
A Venetian blind can go up and down but also it can open and close by adjusting the pivot of the horizontal slats providing great flexibility for privacy control.
Window blind durability is an important consideration in your purchase. Whilst one blind style may be cheaper than another it may in the long run, be better to go with a different style of blind because it is better able to cope with the knock and bumps the it may be subjected to.
Roller blind and Roman blind are quite durable and should last a good while; given that they are not maltreated in anyway. The fabric is the biggest consideration for roller and roman blind and their durability. Some of the fabrics in our deluxe range are treated for stain protection, others are because of their composition are very easy to wipe down .
Aluminium venetian blinds can last for many many years but the slats are the weak point. The slats can bend and stay bent if they are jammed or intentionally mishandled.
Visionwood venetian blinds are extremely durable and colour fast. The main issue with Visionwood venetian blinds is cleaning. There are thankfully many cleaning accessories in the market that lessen this disadvantage. They do not easily bend crack or warp.
Cedar venetian blinds are made from natural timber and have been pre-oiled. The slats will last for a long time however it is recommend to re-oil the slats every two years.
Window Blind ventilation is about the blind being able function with the window open and a breeze gently blowing through.
Roller blinds will knock and bump if the window is open to the breeze
Roman blinds are much softer and whilst they will move around, they are less likely to knock and bump.
Aluminium venetian blinds will rattle if the window is open to the breeze. The use of hold down clips will stop the knock and bump effect.
Visionwood venetian blinds are less likely to make a noise if the window is open to the breeze. Use hold down clips to stop the knock and bump effect.
