BP19 PVC strip with decorative mesh "on the seam" - novelty of the jointless system of building insulation
From the series "Modern facade and wall materials - trends 2020"
Building insulation systems by the BSO method (jointless insulation systems - the "light-wet" method), ETICS(external thermal insulation composite system) with the use of thermal cladding such as Styrofoam and mineral wool is the most common and still - in terms of economy - the most attractive method of insulating external walls of buildings.
In terms of technology, the BSO, ETICS method has remained unchanged for many years. Admittedly, new types of plasters (thin-layer coatings) containing various additives, such as mica, are appearing, which significantly expands the aesthetic qualities of the facade and introduces a variety of new textures on its surface. On the other hand, however, the demand for new tools that allow, in terms of the "light-wet" method, to obtain completely new design and design solutions is so great that new products, materials appear. Bella Plast has been a developer of such solutions for years. Among Bella Plast's novelties prepared for 2020, the following proposal for BP19 PVC "seam" decorative trim is worthy of attention .

BP19 PVC decorative strip "on a seam"
Design and application
The BP19 trim was designed to obtain on the surface of the BSO elevation typical, known from the technique of joining sheet metal on the so-called "seam" - identical external longitudinal grooves. This solution, is perfectly in line with the increasingly common trend of installing flat sheets joined "on the seam" on the facade of buildings.
It is unfortunate that the installation of sheet metal on the walls of buildings poses many technical problems for the contractor. First of all, it is a method taken from roofing, so it requires the use of typical roofing techniques, which, first of all, are not cheap, both from the point of view of the more expensive specialists that roofers undoubtedly are, as well as definitely more expensive construction materials and a much more complicated technique for making such a facade. However, the biggest objections in this case relate to the preparation of the substrate for the sheet, which is wooden battens, unfavorable because of the warping of the wood and to obtain good thermal insulation parameters due to the installation of the battens directly to the building wall and the lack of space to insulate the battens themselves.
Bella Plast's solution, the BP19 PVC strip with decorative mesh "seam" allows on the surface of the facade to obtain the same visual effect as joining sheet metal on the so-called "seam", but already without a whole range of restrictions and problems typical of difficult to process and install flat sheet metal "seam".
Construction and installation
The installation of the BP19 skirting board is analogous to the installation of slats and profiles dedicated to BSO "light-wet" thermal insulation systems. The BP19 skirting board has strips of glass mesh on both sides of the outer seam (PVC body). The glass mesh is mounted to the body by means of ultrasonic welding, which is characterized by high resistance to rupture and guarantees a secure connection between the PVC profile (body) and the strips of glass mesh. Mounting the BP19 strip to the facade surface is intuitive. It is necessary to previously spread glass mesh embedding glue on the thermal cladding and stick the BP19 strip, then the glass mesh strips, with which the BP19 strip is equipped, should be covered with facade glass mesh overlapping from the top and both meshes, in one gluing operation, should be embedded. The next step, of course, is to spread a layer of plaster.
Finishing
BP19 PVC strip with decorative mesh "on the seam" is produced in white technical color, designed to be painted with facade paints such as acrylic, silicate, silicone. The best effect is obtained when the color of the plaster and the color of the paint with which we paint the BP19 strip "on the seam" is the same - then the effect of imitation of tin seam will be the best. It is also possible to produce the BP19 strip colored in the mass in any color, including metallic, silver, etc.
Benefits
Using BP19 trim allows you to shape the view of the facade in a more accessible way and get a good effect of more interesting architecture. It is also worth mentioning that using the BP19 trim completely eliminates the problem of connecting the facade made by the "light-wet" BSO method with the part of the facade where the "seam" sheet is installed. BP19 strip guarantees the uniformity of the system on the entire building. The BP19 PVC strip with "seam" mesh has received protection in the Patent Office of the R.P.
