New design in building insulation by Bella Plast

What attracts attention among the new products for 2021 is the system of PVC façade profiles, including the BP19 and BP11 HTS strips.

The BP19 strip features a shape of a standing seam with a triangular cross-section, while the BP11 HTS profile is the negative of the BP19 strip, being an inverted seam also with a triangular cross-section.

Both strips can be used together or separately. The arrangement of strips on the façade surface is completely free – depending on the actual façade design.

BP19 and BP11 HTS strips can be installed both vertically and horizontally and in any other position. The possibilities provided by combining both profiles on the façade surface are very wide. For example, use the BP11 HTS strips to introduce typical horizontal rustication featuring the shape of a triangle groove, and combine them with the BP19 strips, to make vertical standing seams – that will look similarly to standing seams when joining steel sheets. Another interesting effect is a façade of BP19 strips in a „MATRIX” form, where vertical segments of different lengths are placed at different distances to each other. What particularly draws attention is installing both the BP19 and BP11 HTS strips in the vertical position, alternately the BP19 strip (standing seam) and the BP11 HTS strip – a concave seam (triangular rustication strip).

The installation of BP19 and BP11 HTS strips is similar to the installation of strips and profiles for ETICS thermal insulation systems – the light-wet method. The BP19 and BP11 HTS profiles both feature strips of fibreglass mesh on both sides of the PVC body. The fibreglass mesh is fixed to the body by means of ultrasonic welding, thus ensuring high breaking strength and providing a safe connection of the PVC profile (body) with the fibreglass mesh. Installing the BP19 and BP11 HTS strips on the façade could not be easier. Beforehand, spread the adhesive for embedding the fibreglass mesh on the thermal cladding and to stick the profile, then cover the strips of fibreglass mesh on the profile with façade fibreglass mesh, allowing for some overlap and sink both meshes in adhesive in the same gluing operation. Then, of course, spread a plaster layer.

To install the BP11 HTS strip make a typical groove in the layer of EPS or mineral wool – same as for a traditional rustication profile.

BP19 and BP11 HTS strips come in white technical colour, to be painted with acrylic, silicate and silicone façade paints. For the best effect use the same colour of the plaster and the paint used to paint the profiles. The BP19 and BP11 HTS strips can also be offered coloured in the mass in any colour of the RAL CLASSIC-7 palette, including metallic, silver etc.  The BP19 and BP11 HT façade strip system makes the appearance of the façade more accessible and provides a good effect of more interesting architecture. BP19 and BP11 HTS strips ensure uniformity of the system throughout the building. The BP19 and BP11 HT strips are protected by the Patent Office of the Republic of Poland. The solution is approved for use in construction based on the National Technical Assessment issued by the Building Research Institute in Warsaw.
