On 21.04.2011 on the territory of administrative and production facility of Cheh Plast in Vratsa the traditional annual seminar of the company with all employees took place. Besides the employees who had to exchange experience gained during the year on exhibitions, fairs, business trainings, specialists from our supplying companies were invited as well. This year they were:

- Mr. Zahariev - representative of AGC for Bulgaria - leading glass producer worldwide;

- Mr. Pachev - manager architecture systems in Stilmet AD - Bulgarian leader in the area of aluminium profile systems;

- Mr. Mondeshki - specialist profile systems in Rehau Bulgaria - Cheh Plast has been working with these profiles since the establishment of the company in 2000.

Mr. Zahariev presented to the audience new and not so new but unused by us products of the leader in glass production - AGC. Attractive decision "Top 1,0" which achieves notable indicators related to heat transition from Ug=1,0 W/m2 K, successfully regulates the transition of sun rays with solar factor g=36% and the ability to accept the touch of the surrounding environment (profile colours, colour of next facade) impressed everybody. The attraction was demonstration of advantages and strength indicators of the painted glasses Lacobel of AGC. There was a short movie with examination of Lacobel agglutinated to plasterboard with round shot 0,5 kg from 4,5 m height which could not break the glass. Similar examination but with rubber hammer was made by a volunteer from the company and again the attempt was not successful despite of the efforts and force used.  The objective was demonstration of safety in using Lacobel in bathrooms, kitchens, toilets and other premises and the interesting colour range as well as lack of gaps make them preferred for more clients.

Mr. Pachev told us in details about the changes and technical improvements of the suspended facade E85 which premiere was in the beginning of 2010. What was seen and explained by Mr. Pachev showed the deep work of the Stilmet engineers with use of feedback from the assembly companies that have already used the suspended facade on sites.

Extremely interesting for the whole audience was the presentation of Mr. Pachev related to the newest openable window system E75, meeting the newest requirements for heating, functionality and aesthetics. He pointed out the advantages of this system as elegant straight vision with assembly width of 75 mm, heat transition coefficient Uf from 1,1W/m2K, polyamide tapes from 39 mm, coextruded central pack and additional isolator in the thermal interruption zone. The employees in workshop "Aluminium joinery" and technologists from the company asked questions and asked about details for assembly and link between the case and wall because even if the system is new, we have already completed some orders with window system E75. Mr. Pachev showed specially developed profiles used for water resistant and steam diffusion tapes, for link with heat- and hydro-isolation system of the building.

Last but not least Mr. Mondeshki attracted the audience before the lunch break with new Rehau products launched on the market during the last year. 

After a brief exposé, related to the material from which profiles are produced and its physical and mechanical properties and its safety for humans, Mr. Mondeshki introduced to us the newly developed GENEO profiles.

With them we can satisfy our customers’ desires and produce doors, sliding with lifting, that up to now we made with Brillant Design (five-chamber system 70 mm. construction width).

The need for these new profiles appeared with the enhanced search of windows for passive houses in Western Europe and in Bulgaria, and the passive houses’ front doors and large glazed and opening areas were not feasible without GENEO newly developed profiles.

The representative of Rehau Bulgaria Ltd paid greater attention to the profile system EURO 86, which copies the configuration of GENEO profile system, but the material is traditional.

Euro Design 86 is a reasonable cost solution for low-energy and conventional buildings, because of the heat transfer coefficient of the frame Uf of 1,2 W / m² K (with reinforcement without supplements) and rabbet construction for optimal uptake of triple glazing to 53 mm., more frequently recommended and implemented to the customers.

After one-hour cocktail break in order to refresh ourselves and discuss our experience with the lecturers, the afternoon session of the seminar began. During this session, six employees -Prof. P. Georgiev, Prof. Is. Neshev, Ivaylo Mitov, Eng. V. Galabov, Yoto Yotov and Prof. D. Ivanov - shared what they have seen and learned on their visits to workshops, trainings and fairs abroad. They all had prepared numerous photos, which illustrated their talks.

In the end, we discussed the plan-program of the company for the next 3 years and did analyze the Corrective Preventive Action (CPA) with repeated mistakes, paying attention to all the employees in order to minimize them in the future.
