FAQ's
Blind Boxing what do I need to allow for roller, venetian and shop blinds
Internal blinds
The size is more dependant on the ability of the installer to fit the blind into the brackets than the size of the build up of the cloth or louvres.
Timber grounds should be provided before the recess is created for ease of fixing of the brackets.
For a roller blind the size depends on the roller size, build up of cloth and clearance.
As a guide for blinds up to 1.5m in width and drop allow a minimum of 70mm square, up to 2m in width and drop 90mm and 3m in width and drop 120mm. The exact minimum size will depend on the type of cloth so if it needs to be smaller than these guide sizes check with us.
If it is to retract into a slot with a cover board the board has to be removable for access and the edge of the board has to be smooth as the cloth could rub against it as the roll reduces. The bottom dar should not be designed to retract into the box.
For Venetian blinds the depth of the recess depends on the drop of the blind. This is shown on the product data sheets.
External blinds
The size of the opening should allow for access but should not be too wide to enable birds to penetrate and nest. Maintenance men removing fledglings can be disturbing to occupants!
Creating the recess in the building design can significantly reduce the cost and make the installation less obtrusive when retracted. Suitable fixing grounds should be provided at the bracket fixing positions.
The depth of the box for external Venetian blinds depends on the blind drop and is shown on the Trojan data sheet
It is possible for external roller blinds to be recessed into the building but it is necessary to check your proposals with our technical dept. to ensure that fixing positions are adequate, that the operation is not impeded and that access for maintenance is feasible.
Most awnings are designed for face mounting only and will not close back into a recess box
Shop Blind Boxing
Sprung roller or electric traditional shop blinds fit into a standard opening. Most aluminium framed folding arm types are not suited to a recessed box as the arms have to lift before entering the box and the front rail has to be of a type that closes to the box.
The bottom and back of the box must be zinc or lead lined to prevent water ingress to the building. The end cheeks to which the brackets will be fitted must be securely fixed in position to the building structure.
