How does an anti-condensation coating work?

Water vapor condensing on the surface of the sheet or foil penetrates into the spaces between the fibers of such a coating, thanks to which drops do not form. The higher the grammage of the nonwoven fabric, the more condensation this coating can accumulate. Some non-woven fabrics can retain up to 1000 g of water per 1 m² of sheet metal or foil. It is worth remembering that the coating stores water only during periods of increased air humidity and only to release it when drier air arrives. It therefore stores water in an amount regulated by the ventilation of the roof or covering.

Easy and quick assembly of the SuperStrong steel garage - do it yourself!

Do you know what you can gain by choosing this type of garage? SuperStrong's frame structure allows it to be installed on any surface! This means that it can be placed both on cubes, concrete and directly on the ground. This is possible thanks to the previously mentioned screws, screwed in to a depth of almost one meter. What does the installation look like in practice? Can you handle this task yourself or will it be necessary to call a professional team? The manufacturer took care of all the details, so you can complete the task yourself. All components and the entire structure of the SuperStrong sheet metal garage with a sectional garage door fit on one pallet and are carefully assembled and described.

If you intend to place the structure on the ground, it will be necessary to prepare the ground first, i.e. remove the top layer of several centimeters. After screwing in the metal pins, proceed to the assembly of the skeleton reinforcing structure. The next step is to screw the side walls. In the final stage, you will only need a sectional garage door, which can be equipped with a manual handle or automatic control. As you can see, SuperStrong assembly consists of several basic stepsthat even a less experienced DIYer can handle.

By choosing a SuperStrong steel garage, you gain the opportunity to equip it with additional amenities that will make the structure fully meet your expectations. A practical option is to install an additional entrance door, which will make it easier for you to enter the interior without having to lift the main sectional garage door each time. If you want to have a view of the outside while staying inside, decide to equip one of the walls with functional glazing as a window. Although the structure of the garage guarantees its tightness, it is worth considering installing a gutter to increase the level of safety.

If you are looking for a solid solution that will protect your vehicle even in the most difficult weather conditions at any time of the year - decide to purchase a SuperStrong steel garage with a sectional garage door, which innovative frame structure ensures exceptional durability.
