The UNI EN 12216:2005 standard, “Shutters, interior and exterior shades – Terminology, glossary and definitions,” has attempted to clarify things, but for a “clear” distinction one must refer also to the standards for CE marking. It can be inferred that (UNI EN 13659:2004) shutter should be understood as guided Venetian blinds; sliding, swinging and folding shutters; wing shutters; sliding panels and roll-up type (roller shutters). Solar screens instead (UNI EN 13561:2004) are all the various types of shades (free hanging, roll-up, supported by arms) and awnings, i.e. elements that are horizontal, vertical or projecting from the building envelope, which have the task of protecting the building walls and windows from sunlight. Therefore, although slight, the main difference lies in the effect produced: the former, i.e. shutters, as suggested by the word itself, not only darken, but also always shut or close windows and/or doors; solar screens serve only in the presence of sunlight.
Yes, always. By their nature, in bad weather conditions they can break or tear, and thus they need to be protected with suitable devices (if motorized) or closed by the user (if manually operated), also because their main job is to protect against the sun.
The size of the canister and the flexure of the retractor roller. Plus, since the introduction of the CE marking, the size of the sample tested by the manufacturer.
Legislative Decree 311/2006 establishes that solar screens are mandatory for buildings greater than 1000 m2. The greatest effectiveness is obtained with exterior sunshades (which can reduce air conditioning costs by up to 60%), especially with dark fabrics (greater heat absorption). If installed inside, light fabrics are preferable (less heat absorption). The best performance is obtained with Sunscreen and Soltis.
Insects, and not just mosquitoes, are not only bothersome but may also carry a number of diseases: it’s best to keep them as far away as possible from people and their homes. It also reduces the use of insecticides (harmful to man and the environment) and contributes to energy saving (it is easier to ventilate rooms during the cooler hours).
It is advisable to measure height and width in at least 2 to 3 places of the window opening (at top and bottom, left and right, and in the middle). Use the smallest dimensions, for both height and width.
For most products (especially roll-up screens) it is a very simple operation, made easier by the instructions enclosed with the product. For some types installation requires more attention, but no special skills.
It is an inertial safety device that, by opposing the force of the spring, slows down the speed at which the mesh retracts and, consequently, that of the rising of the aluminum bar handle, and avoids unpleasant accidents, especially when the screen is large. In fact, with the increasing of the size, the force required to retract the mesh also increases, and the greater is the retracting force and the greater the resistance created by the device: the result is a more uniform, and less hazardous, retraction.
It is a certificate of conformity of a product to specific safety requirements established by one or more EU directives. It is identified by a special logo that is valid throughout the European Union.
Generally it is the manufacturer who, under its own responsibility, affixes the CE logo. The presence of the seal indicates that the product is in compliance with the Community regulations relating to it.
There are various directives, to which the manufacturer must refer, that establish whether “self-certification” is sufficient, given the simplicity of the standard, or if it is necessary to resort to laboratories or certification bodies. For insect screens and solar screens, it is the manufacturer who, assuming responsibility, declares that their products are in compliance with the EU standards.
Generally yes, although it depends, of course, on the extent of the damage. The most frequent repair is the replacement of the screen mesh after it has been accidentally pushed or knocked into forcefully.
Cleaning. At least once a year remove dust or other residues from the mesh, by sponging it gently with warm water and a mild detergent or with a soft bristle brush. If the mesh should come out from the guides while doing this, open and close the screen slowly. The aluminum can be cleaned with a damp cloth.
