Residential facilities are the core part of activity for Wiazar-System. We focus on quality and precision of our prefabricated elements. We are aware of the importance of warmth and safety for of customers, so we make every effort to make these available to them. Choice of nail plates and sections of solid wood is not a discretionary design method, as it is in the case of a traditional timber roof truss developed by designers in studios and frequently manufactured in an altered form by carpenters on the construction site.

The quite common use of practised schemes resulted in widespread use of wooden cross-sections for traditional timber roof trusses with cross-sections that are too large and not related to actual tension they should be exposed to. This generates costs and increases the weight of the structure.

In the case of prefabricated trusses, the entire production process begins in the design studio where a skilled constructor uses specialist licensed software for such products. The constructor makes static and strength calculations to adapt the attic trusses to the required spacing and span. At this stage one might focus on every single truss so as to make it adapted to the investor’s needs in terms of width and height of the room, taking into account the strength conditions. The design provides an opportunity of economical distribution of material for typical or individual construction solutions. Such a project prepared in the form of an electronic file is transferred to numerically controlled saws that cut the previously impregnated lumber under the supervision of their operators. All of the elements of this system along with galvanised metal fasteners in the form of nail plates are manually or laser-dismantled in line with the guidelines of a given project. The last step of such production process is to press the plates into wooden elements using hydraulic presses with adjustable compression up to 40 t.

The entire production is planned in detail with an emphasis
on maintaining the highest quality at a reasonable price,
because it is customer satisfaction that we care about most.

Single-family buildings
Pent roofs, gable roofs and multi hipped roofs correspond to the Polish centuries-old tradition of building roofing. Their structure has much evolved in the latest years and the historical 'thatch' was exchanged into modern decorative building materials. The load-bearing roof frame was shaped in the form of usable floor space or as a loft. The basic assumption is that all surface areas have a specific pitch angle and its degree, determined by the development conditions, defines the type of roof covering in terms of aesthetics, functional economy and thermal material characteristics. Prefabricated roof structures are used worldwide for this type of facilities today. This systemic solution consists in use of nail plates as fasteners for solid wood elements with proper height and width. All of the trusses manufactured by our plant are a result of combinatorics calculations of given loads, which guarantees incomparable safety and resistance compared to the traditional timber roof truss.
Multi-family buildings
Designers have lately noticed an individual trend in roofing-development of usable attic space. The objective of such solutions is to make usable floor space as large as possible, at the lowest possible cost. Today investors on the market are taking to these solutions and using them mostly for construction of single-family houses, taking into account that the family using the house might enlarge. Developers offering multi-family complexes have also noticed the benefits of attic conversion at the very design stage, which allows them to obtain greater revenue from sales even later, when the price increases over time on account of the increasing popularity of the given location. Our company offers free advisory and cooperation with companies developing housing estates and multi-family complexes. Depending on the stage of development we might adapt to the existing project layout or offer custom-made roofing solutions at the design stage.
