Skylight blinds is a blind category that was developed for solving a series of problems regarding sun protection when the windows are inclined.
This product category is composed of:
- textile roller blinds
- pleated blinds or cellular pleated blinds
- aluminum venetian blinds
Each of these products has the following standard parts (these standard parts have the same functions but may differ from the point of view of the shape):
- superior coverage profile
- main sun protection product
- closing rod
- lateral guiding systems
This category of products has a series of advantages:
- they are easy to mount, their installation being similar for all the products in the category
- they fit perfectly to the design of the window, not having any visible pining elements (clamps, bolts, etc.)
- they have been conceived modularly, all the products having the same basic elements
- they can be used for any type of attic windows
- the design of the products is similar, regardless of the basic product
- they can be mounted on any type of inclined window (there are adjusting elements which allow problem free mounting for different inclination angles of the interior wall of the window frame 90 o – 105 o)
Due to the fact that none of the classic systems has a stopping system in an intermediary position on an inclined plan, at the SKYLIGHT type products there is a pre-tensed lateral cords system that allows stopping the product in any intermediary position. Also, the cord system allows a permanent maintenance of the parallel position between the closing rod and the lower margin of the window.
The upper covering profile is made of aluminum and plays the role of fastening the protection mechanism to the upper part of the window. This profile can be pinned with special clamps, by clipping. They are specially designed in order to perform a correct pinning at an inclination of the interior wall of the frame of 90o, 96o or 105o. (standard inclinations for attic windows). The VELUX windows, the most common on the Romanian market, have an inclination of 96o.
The main sun-protection product may be one of the following:
- roller blind
- pleated blinds or cellular pleated blinds
- aluminum venetian blinds
- a combination between two products: roller blind and pleated blind.
The closing rod is made of aluminum and has the role of allowing the lifting/lowering of the product.
The lateral guiding systems are made of aluminum and have the role of allowing the sliding of the closing rod and closing the existent pre-tensed cords systems. In the upper part they usually slide under the front part of the -upper coverage profile. In the lower part they have special plugs. These guiding systems may be pinned to the interior wall of the frame, inclined to 90o or 96o. If the inclination is 105o it is necessary to have a special “filling” profile which is inserted between the window frame and the lateral guiding system.
1. Roller blind
This can be made in two versions:
- with lateral guiding system
- without lateral guiding system
The second version is less used, it has the advantage that it can be easily fastened in length, but it requires lateral fixing hooks and does not assure a satisfactory “lighting” sealing.
The textile material is applied on a tube on a self-adhesive stripe. The tube does not have the same width with the material because this must be fixed with special rivets in order to retain the material.
A spring is inserted in the axle for the tensioning of the textile material. This spring is pre-tensed at mounting in order for the material to remain stretched. The axle is masked by the upper coverage profile being fixed in the lateral ends of this profile. The closing rod is fixed on the fabric with a plastic strip inserted in it. The material and the closing rod shall slide at the level of the guiding systems.
The closing rod is fitted with a rubber gasket in order to assure a perfect closing (from the point of view of the light) if the roller-shutter is lowered. The lateral rivets that are fixed on the material shall not allow the material to “get away” from the lateral guiding systems, holding it stretched.
A pinion fixing system has been inserted in the lower part of the guiding systems in order to prevent the accidental opening of the roller-shutter. (due to the spring tensioning, tensioning which increases with the lowering of the roller-shutter, this has the tendency to elevate uncontrollably). The cord system that assures the correct functioning of the roller shutter moves from the end of the profile from the upper part, along the guiding systems and through the closing rod.
2. Pleated blinds cellular pleated blinds
This product may be designed in different versions
- with a single pleated element..
- a combination of two pleated products.
- a product which actions independently
The material is inserted in a plastic profile which is fixed by clipping in the upper coverage profile. The textile material is fixed at both ends in order to be sure that it cannot escape from the upper profile or the closing rod. The perforation of the material and the profiles (upper and the closing rod) is made in the same position. The number of chain necessary depends on the dimension of the product and the type of the material. In the holes of the profile (upper and closing rod) gaskets are inserted which have the role of preventing the direct friction between the cord and the profile, friction which may lead to the deterioration of the cord. The cords’ system is tensioned with a spring which is inserted at the level of the closing rod. In the product commanded independently there is no upper coverage profile but there are two closing rods. In this case the product can be elevated and lowered freely.
3. Combined roller blind with pleated or cellular pleated blind
This product is a combination of a textile roller-shutter in the upper part with pleated blind in the lower part. Both products are assembled separately and are only mounted together when the products are installed on the window frame.
The upper profile of the pleated blind is clipped on the closing rod of the roller-shutter using a special connecting profile and special profile ends. Of course, in this case the closing rod is not fitted with rubber basket.
4. Aluminum venetian blinds
This can be made in two versions:
- completely manually driven
- with electric rotation
On the upper profile the slats rotation mechanism is fixed (supports and bushes for the ladder and the orientation mechanism for the inclination degree of the slats). The bushes for the blind’s ladder are clipped to the bush support. An axle is passed through these bushes and connected with the rotation element: manual or electric motor orientation mechanism.
For the manual command, the orientation mechanism is commanded through a button placed on the front part of the upper coverage profile. When the button is rotated it sends this movement through the orientation mechanism, the axle, the bushes and the ladder to the slats of the blind determining the opening or closing of the slats. In case of electric command, the role of the orientation mechanism is taken over by a motor powered by batteries. The motor is fixed with two special supports to the upper profile. The infrared receptor which takes over the command from a remote control is placed within the upper coverage profile (which is perforated for the sensor to be visible). Also, on the inner part of the upper profile is also placed the batteries system.
The aluminum slats, regardless if they are of 35mm or 25mm, are processed specially to perform the sliding system. The slats are cut up and an oval hole is made through which a cord is passed. This will assure the lateral fixing of the blind.
The closing rod is fixed to the ladder with special plugs, in the lower part of the closing rod.
The closing rod is fitted with special closing rod ends. There are two elements which slide on the lateral guiding systems and which are connected to the ends of the closing rod. The connection system allows the closing rod to rotate around the longitudinal axle together with the rotation of the aluminum slats on the command of the orientation mechanism.
The fixing cord avoids the contact between the aluminum slats and the lateral guiding systems reducing their wear and the noises which may appear when maneuvering the blind.
The closing rod is used for elevating/lowering the blind. The aluminum slats may be rotated either manually with the help of the front button or by remote control for the electric system.
For the manual rotation a stick connector can be used and a stick for the remote control of the blind. The stick connector is inserted in the front command button.
Especially easy, specific to each basic product:
a. Pleated / cellular pleated:
- a monthly wipe of the dust from the textile material and the mechanisms is recommended using a brush or an electrostatic duster.
- quarterly, after removing the dust, it will be proceeded to washing the material.
In order to wash the material this is taken off the command mechanism, then the command chains are removed and the material is washed in water with a maximum temperature of 40o, is rinsed and dried carefully. Then the material is reattached to the mechanism and the command system is mounted.
b. Roller blind
- monthly wipe of the dust from the textile material is recommended using a brush or an electrostatic duster.
- anytime necessary, after removing the dust, it will be proceeded to cleaning the material by washing or wiping with a sponge, in water with a maximum temperature of 40o.
The material is impregnated and does not require ironing.
c. Venetian blind
a monthly wipe of the dust from the slats is recommended using a brush or an electrostatic duster.
Anytime necessary, after removing the dust, it will be proceeded to cleaning the slats by washing with a sponge in water with a maximum temperature of 40o.
