Acrylcolor

In the coextrusion coloring process, the white PVC base body and the colored acrylic glass are inextricably bonded in a single process. This fusion of the two materials produces a colored satin exterior surface that is able to resist atmospheric factors without problem.

The hard acrylic surface is scratch resistant. Thus, acrylcolor windows are among the strongest building components. With a thickness of 0.5 mm, the acrylic layer is thicker than that of any varnish. In case of surface scratches, there is enough reserve material to polish and remove them.

The indissoluble bond and hard surface prevent the color layer from chipping or peeling.

Acrylic glass is a material that maintains color strength for a long time and does not fade. The rear lights of cars are an illustrative example of the properties of this material.

As a component of the exterior façade, the window profiles are especially exposed to solar radiation and atmospheric, climatological and mechanical factors. In order for colored windows to continue looking beautiful over the years, it is necessary to use profiles that resist these loads. With the acrylcolor profiles from GEALAN you can be sure. Acrylic glass has proven its resistance to atmospheric factors over the years in billions of vehicle taillights.

The non-porous surface makes acrylcolor windows easy to clean. The elegant brushed effect also improves its resistance to dirt.

And should visible scratches appear on the profile, these can be easily removed with a Scotch Brite pad.

STV®

GEALAN-STV® is the revolutionary system for dry bonding glass and sheet overlap. Compared to conventional wet processes, it has decisive advantages, and that, without affecting the ease of processing. STV® is a system that really works.

STV® static dry glazing does not imply significant investments in new machinery because the profiles are already supplied with the integrated adhesive tape.

Profiles are processed in the usual way. Cutting, welding and plastering can be carried out as usual with minimal adaptations to STV® requirements.

The combination of STV® technology with conventional steel reinforcements allows to manufacture elements of sizes impossible to date. In special constructions, it also allows more stable elements to be realized.

In the construction of white elements of normal sizes (windows of 1.50 x 1.50 m and balcony doors of 1.10 x 2.30 m) with STV® technology, steel reinforcements can be completely dispensed with. This achieves a significant improvement in Uf values (up to 0.2 W / (m²K) depending on the profile combination).

Adjustment or correction work on the window is reduced to a minimum. In addition, the weight reduction greatly facilitates the assembly of the elements.

All STV® components have been verified in accordance with the valid RAL regulations for glued constructions and represent the latest technological advances. The values achieved are equivalent to the usual efficiency classes of GEALAN profile systems.

The STV® (static dry glazing) gluing technology developed by GEALAN consists of gluing the glass and the profile sheet with an adhesive tape specially designed for window construction, maintaining the usual glass wedge. By gluing the glass to the profile of the sash, the stiffness of the glass is transferred to the sash, which improves the stability of the entire system. This allows standard elements to be manufactured without steel. Alternatively, more stable elements can be manufactured in combination with steel and the GEALAN STV® system. In addition, special constructions allow to significantly improve the rigidity of round arches and sloping windows.

GEALAN’s STV® offers for the first time window builders an advanced system for the rational and cost-effective manufacture of glued-glass windows.

GEALAN is one of the leading European manufacturers of PVC profiles.

Modern profile systems such as the GEALAN-KUBUS® system, the S 9000 combination system and product innovations such as STV® dry glazing, IKD® thermally insulated core and acrylcolor window profiles are some of the main competences of the GEALAN brand.
