Louvre grilles – Perfection of solutions, competitive price!

Our company has in its range of products louvered grilles (ZhR).
Production is aimed not only at large wholesale customers with a large number of identical products, but also at individual production of private orders according to your sizes. Programming of the machines is possible in such a way that we can produce for you several different ZhR and all of them can be of different sizes and absolutely any area in the world. High-quality production of metal louver grilles can only be achieved using the bending method. In special cases, when bending technology cannot be used for various reasons, the frame can be made from profile pipes of various sections. Typically a profile pipe of 40*25, 50*25 or 60*30 is used.

ZhR lamellas can be produced in two ways: Z-shaped and L-shaped lamellas from cold-rolled steel. The latter is considered today to be the more progressive and least expensive manufacturing method.

Z-shaped slats	L-shaped lamellas	perforated louver grille

Scope of application for external louvered grilles.

The most common use of external louvered grilles in transformer substations is for air circulation in the chamber, to protect supply ventilation channels, in technical rooms, and can be used as decoration for building facades. It’s not uncommon to find LR installed in the gables of private houses. Here they perform decorative functions, installed in blind or dormer windows. To integrate with the color of the facade, painting can be done according to the RAL color catalog using powder coating.

Classification of metal louvered grilles.

We divide metal louver grilles into fixed and hinged ones.
They can also be single-section or composed of several parts. In this case, the position of the lamellas is always permanently open to the inflow. They can be absolutely varied in geometric shape: rectangular, round, triangular, trapezoidal or polygonal and other irregular shapes.

How to order?

The manufacturing steps are as follows:

You contact our manager in any available way, place an order for a surveyor to visit online or call +.

The surveyor on site explains all controversial issues and nuances, after which he makes measurements and calculations.

The prepayment is no more than 30% of the total amount, which will be indicated at the conclusion of the contract.

The design is completed within 3-4 days from the date of execution of the contract.

Installation is carried out on the agreed day, while payment is made only after signing the acceptance certificate.

Assembly and installation of louvered grilles in openings.

Initially, it is assumed that metal louver grilles are installed in prepared openings where there is room for them. If windows or other objects are installed flush and there is no place to attach the frame, then the structure is made overlay. What does it mean? Increases the area in the light. The ZhR frame is made slightly larger than the opening itself; as a rule, 2.5-4 cm are added on each side. Thus, the frame lies on top of the opening. Fastening ears are produced from it, through which they are fixed to the wall or welded to a metal frame, if there is one.

Assembly and installation of louvered grilles can be carried out either by welding or by means of threaded connections with screws or self-tapping screws. As a rule, this does not take much time, since initially all the technological holes and lugs are already prepared in production.

What are louvered dormer windows used for?

Modern building codes impose a whole range of requirements for the organization of roofing of buildings. It must meet the parameters of stability and resistance to any type of precipitation, sunlight, temperature changes and other negative factors. One of the important elements is the ventilation system, which ensures high-quality air movement inside the roofing pie.

Why do you need louvered grilles for dormer windows?

The absence of a normal ventilation system can lead to the active accumulation of fumes and condensation, which, in turn, leads to gradual rotting and destruction of materials. A special dormer window is designed to help normalize the level of air humidity, onto which a louvre-type ventilation grille is installed.

A dormer window is an opening specially cut into the roof to provide access to the attic space and normal air circulation. This procedure must be taken into account when designing a house, since the durability of roofing materials depends on it. High-quality ventilation grilles help cope with condensation and create a healthy microclimate in the attic, providing the ability to store various household items there.

The installation of louvered grilles made of metal or plastic allows you to protect the interior of the attic from the entry of precipitation, birds or debris raised by gusts of wind. Reliable grilles for dormer windows must be highly durable, so the main material for production is usually metal or reinforced plastic.

Experts identify two main functions that louvered grilles perform:

1) Decorative. The grille, visible from the street, should look stylish and fit into the interior of the building without disturbing the overall harmony of the design.

2) Protective. In addition to preventing solid foreign objects from getting inside, some ventilation grilles have lintels equipped with special raindrop catchers that prevent moisture from entering the room. Often their profile is made in the form of the Latin letters S or Z. This shape additionally protects the dormer window from atmospheric influences.

History of the name

Many have heard this name, but not everyone knows why it is called that. Referring to V. Dahl’s interpretative dictionary, in the category “Hearing”, the term stands alongside “for hearing”, “vent”.

The author designated the phrases “dormer window” and “hearing in the roof”, with the note “although there is nothing to listen to here.” Also, Dahl gives the phrase “rumors blow with the wind.” It's not for nothing. Once upon a time, such windows were in the premises for service personnel. As a rule, the servants loved gossip and gossiped “from the heart.” So much so that parts of the conversations could be caught through the windows.

The second explanation for the origin of the definition refers to the Manege in Moscow, built in 1817. It was erected as a tribute to the destruction of Napoleon's army. During the construction, a team of a local master, Slukhov, was involved. He was a well-known roofing specialist and, in fact, was responsible for this work in Manege.

The original design of the building did not include such windows, and ventilation of the attic was not provided. One day, in the heat, the surface of the attic became so hot that the roofing began to deform. The incident was reported to Alexander I, and the work had to be corrected urgently. Slukhov then proposed placing a row of windows on the slopes to ventilate the room. Since then, such structural elements have been named after the name of this master.

Then they came up with another use for lucarnes (their second name) - they began to make this invention to reduce the load on the ceiling, in which the installed beams sagged and could not support the mass of the impressive span. The significant draft created by the windows created a zone of reduced pressure above the ceiling. Therefore, the weight impact on the ceiling was reduced and a serious accident was avoided.

Decorative ventilation grilles Snegos

Decorative ventilation grilles are used as air intake and exhaust, and also protect ventilation shafts from foreign objects (debris, birds). The grilles are mounted at the exits of ventilation shafts, in the openings of the attic dormer windows.
