Each glass facades facade design is done on an individual project. Facade system based on the profiles of different systems allow you to create designs out of plastic, steel and glass elements mullion-transom way. Glazing can be accomplished with the use of float glass and glass. Thanks to the consistent thermal separation of external and internal profiles achieve high thermal insulation. Glazing of balconies and loggias of the manufacture of window designs, balcony glazing and loggias use window units, made of aluminum profiles with thermal, mandatory for our climate. It is a 2-chamber windows with triple glazing. In addition to excellent thermal insulation and insulation, aluminum window designs provide individual opportunities for design of your home.

Translucent structures – roofs, conservatories, bay windows, translucent design, conservatories, bay windows, photoconductive roof by our experts, a great opportunity to add personality to your home or office. In the design of the aluminum structure takes into account all factors affecting the microclimate photoconductive structure. Aluminum structures are widely used for the manufacture of these elements: doors, windows and partitions and successfully compete with other materials. For more complex systems, such as glass dome buildings, aluminum facades and winter gardens – aluminum construction, perhaps the only suitable material. If you believe the encyclopedias, aluminum is the most common metal. However, its use in aluminum designs due to its physical and mechanical properties. High strength aluminum with a low specific gravity can produce aluminum construction to withstand heavy weight and still remain themselves light. Plasticity of the aluminum and the ability to take any form make it an indispensable material in the manufacture of complex aluminum facades and aluminum structures of irregular shape and large size.

Plywood Class

meter of surface. Plywood second-class standard, can have knot diameter not exceeding 40 mm, plywood third grade there may be knots maximum diameter of 70 mm. On the plywood of the fourth grade this indicator .Chastichno accreted, unjoint, loose knots, knot holes and wormholes. This kind of defects are totally unacceptable a veneer of elite varieties. Plywood Class I: may be up to three listed defects per 1 sq.m. surface, if their diameter is less than 6 mm or 10 mm if the hole sealed with putty. Plywood second grade: standard allows the presence of no more than 6 such defects per 1 sq.m. diameter of 6 mm, clamped putty – 15 mm.

Plywood third grade: it is assumed the existence of an unlimited number of these defects with a diameter up to 100 mm, plywood fourth grade are allowed any number of defects with a diameter up to 400 mm. Closed splits. Serried edge cracks should be held tightly to each other. Plywood elite class does not admit the existence of these defects. Plywood grades 1.4 allows unlimited number of cracks, provided that they do not impair performance characteristics. Diverged cracks. Standard does not permit the presence of dispersed cracks in the elite grade plywood. In the first plywood varieties may be present 1.2 cracks up to 250 mm and a thickness of 3 mm, if they are sealed with putty. In plywood Class ii 3.1 crack lengths up to 400 mm in diameter and 5 mm. Plywood 3 grades: 1-3 cracked up to 600 mm, a width of 10 mm.

Sanitary Silicone Sealant, As It Is Chosen ?

Construction markets of almost all regions are literally awash with silicone sealant. Manufacturers and suppliers do not find it. Competing in the price of silicon sealants are no longer on the cu and cents, and not even the ruble, but on a dime. Average price kartushirovannogo (packed in a plastic cartridge with a spout) sealant is 55-60 rubles for a volume filling 260 – 310 ml. The price of wholesale importers, privozyaschih sealant in Russia is 36-40 rubles. – But why all this? – You ask. The answer: The fact that in recent years have increasingly heard the question: – Why sanitary silicone sealant in the bathroom (toilet, bath, etc.) suddenly darkens (Turns black)?

Let’s the same, we still see, what we buy for 60 rubles. First: What is silicone? Actually, it includes: * silicone rubber, * filler (pigment) * tiksotropiruschy (removes flow) agent, plasticizer * (increase the plasticity and elasticity) additives, fungicides * (antifungal) Supplements * catalyst (polymerization activator). Ratio of those ingredients in order listed should be approximately as follows: 45%, 45%, 4%, 4%, 1%, 1%.
