Aluminum Rolling Shutters Toronto

Toronto Aluminum shutter makes up the largest portion in the market of roller shutters. Therefore, we should pay close attention to the technological characteristics of the shutters and its types, consider the main parameters.

Firstly, the production technology. There are two methods for shutter production: extrusion and rolling. The extrusion method makes it possible to produce a solid profile which is more durable in comparison with rolling, has thick walls and a complex cross-section configuration. This increases its protective properties, but the voids inside the profile have a bad effect on its thermal insulation properties. The rolling method is used to make foam filled shutters. This rolling shutter has lower stiffness compared to extruded shutters, but better insulation performance due to polyurethane foam filling.

Thus, both profiles are good, but their functions differ.

Secondly, the quality of aluminum and its thickness. You don’t have to be an expert to assess the quality of a rolling shutter, just look at the profile in the section and try to press it. If the aluminum is low-quality and walls are thin, the profile will give in to pressure, even with a little effort.

The conclusion is simple: the residential roller shutter will provide sufficient protective properties. In addition to the thickness and quality of the shutters, it is also worth paying attention to its height, since it is the height that determines the sphere of use of the rolling shutters. Different manufacturers have their own lines of shutters, but we will try to derive averaged figures.

The conclusion is simple: the roller shutter will not provide sufficient protective properties. In addition to the thickness and quality of the shutters, it is also worth paying attention to its height, since it is the height that determines the sphere of use of the rolling shutters. Different manufacturers have their own lines of shutters, but we will try to derive averaged figures.

Fourthly, the quality of the paintwork. The paint coating is not just a decorative solution, as it may seem at first glance; it is the key to the durability of the roller shutter. The high-quality coating prevents various chemical (corrosion) and physical (abrasion) processes, which affects the service life of roller shutters. So, when choosing a profile, you should pay attention to the coating. If the paint peels off, is applied unevenly, there are air bubbles – such profile will not last for a long time.

Many manufacturers reduce the density of filling for sake of cost-cutting, making it softer, looser and allowing for the appearance of voids. This adversely affects the properties of the profile: the density of the sheet, heat insulation, and sound insulation. All these functions performed by roller shutter systems suffer from savings on production technology. But the most critical moment in poor-quality foam filling is the deformation of the roller shutter during operation. As in the case of aluminum quality, polyurethane foam is easy to “feel”.

Thirdly, the type of foam. Today, virtually all aluminum profiles with foam filling use polyurethane foam. The only difference is in the quality of this filling.

Special purpose shutters

Perforated profile. Its only difference from the usual profile is the perforations near the lock part. The function of these holes is the access of diffused light. The main field of application of the perforated profile is the private sector, thus the roller shutter acts as a sun protection system.
