The new word in ventfasada: composition crate under the siding

Comparison of wood, metal and plastic sub-systems, installation nuances

Siding and a variety of front and plinth panel consistently popular with suburban real estate owners for many reasons. This increase in heat-saving parameters through the use of in the "pie" of insulation, and the ability to dramatically improve the appearance of the house, regardless of the wall material and the absence of wet processes, and relatively simple technology installation. The key to the reliability and durability attractiveness of such a cladding is lathing - subsystem providing not only the flat surface necessary for the topcoat, but also ventilation, prevents moisture and thermal insulation walls.

Until recently, there were only two types of subsystems, wood and metal, but today there was an alternative option - a polymeric sheathing. With the help of a specialist company Alta profile, consider what is the crate in general, and in particular polymer, and whether it has advantages over the usual types.

Crate - and functional characteristics

Like any subsystem crate is an integral part of a ventilated facade system and performs a series of tasks:

• the basis for fixing the finishing material;
• fixing heater (when mounting vraspor);
• alignment of the base;
• ventzazora device for smooth circulation of air masses.

Even with perfectly flat wall mount and panel siding directly without subsystem, is not recommended, and is fraught with big problems with the facade in the near future. And it's not only about the possible deformations of the lining after the foundation, but also the over-wetting the walls due to lack of ventilation.

Lathing is a spatial frame of rails mounted on the wall by means of hardware or suspensions, with a certain gap.

In most cases, the guides are mounted vertically, the horizontal orientation is less common (vertical mounting cladding). Insulation materials are placed between the guides or, if facing layer allows an appropriate distance, or going over the crate. Step between the guides depends on the presence of insulation, and on the characteristics of the liner - the screen will be heavier, the stronger must be the frame therefore less step. For crates under the vinyl siding the recommended distance is 400 mm, if windy side - 300 mm.

Sometimes this distance is increased, but, like the retreat is only possible under certain conditions.

I took a step of 500 mm. Than it threatens me?

Yes especially anything, with proper installation and quality siding. In the worst case - facing vertical float in waves with dips exactly, between the battens. But this is - at worst. And so - should be fine ...

Is it worth risking, everyone decides for themselves.

Compare subsystems

Consider wooden, metallic and polymeric subsystem detail and compare their options.

wooden crate

Option for the private sector, as a budget alternative to the metal partition as lumber cheaper. Usually use dry bar section 50 × 50 mm, but variations are possible in a small range that does not play a fundamental role. To the front of wooden crate often attached directly, nails or screws, at least, through the wooden spacers. To protect the wood the whole timber is pretreated impregnation - or universal, direct and antiseptic, and a biocide, and a flame retardant, or alternately. But even if the processing wooden crate is not used on the base, since in this zone humidity.

metal lathing

Subsystem considerably more expensive and "come" in the private sector of a multi-storey building - lathing collected from galvanized profile section 60 × 27 mm. To facade rack attached by hangers - perforated metal bands curved in the shape of the letter "P". Since zinc layer protects the metal from corrosion, metal lath used in any conditions, including the base.

polymer crate

innovative subsystemRecently appeared on the market - instead of wood and metal, all the elements are made of high strength plastic. It is not due to moisture, it does not rot, is not corroded and does not require protective impregnations. In addition, the special structure of the profiles, thereby improving the ventilation of the façade, and the shape of the guide is designed taking into account the configuration of the lining and repeats the geometry of the panels.

If thermal insulation is applied, the plates are mounted on the pins by piercing, as with a metal mounting subsystem.

The performance characteristics of the polymer crate is not inferior to any wood or metal.

My sister is going to warm the house and to sheathe siding or panels, are now considering crate. We heard that there was a polymer subsystem, but there is almost no information. That does not rot and does not rust, it is clear on it and plastic, and that strength, even if it is comparable to a tree, not to mention the metal? And there are some differences in the installation (step between the rails)?

Durability crates in no way inferior to both metal and wood. Durability is primarily due to the flexibility and elasticity of the material, which is under the influence of mechanical will absorb the loads and to return to its original position, that is not true of metal counterparts. As for installation, here we rely on the usual profile installation experience in metal and wood. The main feature is the surface on which the installation occurs. Step crates recommended 30-40 cm. Because lathing the polymer, it has a linear expansion, and each profile in the dock with each other has a so-called "whiskers", which is placed on top of the next profile.

And the life of the polymeric subsystem level.

We are also interested in a plastic crate under the siding, but the real experience and the reviews did not find. Wood and metal are already checked, though with its own characteristics. For example, like this crates with durability, taking into account that in summer the temperature exceeds the limit, especially when facing a dark and cold winter crush?

Daniel Chizhikov

Durability of polymeric batten exceed the mark of50 years. Its resistance to external conditions is very high due to the polymeric material itself. Because lathing the polymer, it has a linear expansion, and each profile in the dock with each other has a so-called "whiskers", which is placed on top of the next profile. Due to a similar linear expansion with finishing materials, we virtually eliminates the risk of "jurisdiction" and deformation as the material itself and the battens profiles.

That is, the polymer crate is not only not inferior to wood and metal on the technical characteristics, but also preferable in some respects.

• Equal linear expansion.
• Constructive profile.
• Profile geometry, repeating geometry siding panels.

As for the cost, then the metal and polymer is comparable, but the wood is cheaper, if not to take into account the cost of impregnation and self-drying wet timber.

Especially polymeric batten installation

It is subsystem in a conventional manner, with the difference that the meter profiles and joints more often, because of what can some increase build time frame, but it is possible to edit the material alone for instructions. With regard to the attachment to the facade, there are several ways.

Daniel Chizhikov

Crate itself can be mounted in three different ways:

• In the so-called "glasses" (holes for screws) to a flat surface, e.g.OSB;
• In suspensions, using the "mounting laths" (suitable for any type of facade);
• To "studs" to adjust the level profile (can be used with dowel fungi, suitable for any type of facade, especially with rough walls).

Together with the subsystem is a clear instruction in the public domain a video installation example. But sometimes after watching the questions remain.

Acquainted with the roller installation polymeric subsystem. It is interesting that in the video crate attached to the perforated metal holders. Obviously taken with metal battens, although promoting the plastic screws on the plastic base. Unclear.

Bottom structure horizontally fixed plastic profile. Whether it will interfere with ventilation? Or starting bar often need to be fixed horizontally?

By the way, the reliability of crates compared to metal sheets? Not inferior?

Daniel Chizhikov

For the more usual method of installation We have developed an additional element - "mounting pad", which allows you to set profiles batten on all the usual metal hangers. It is one of three options for its installation, that allows the use of a polymer crate on the surfaces of any complexity.
The lower profile is mounted horizontally for easy mounting of the metal low tide, if you are installing material without reflux, you will have enough vertical profiles only.
The profile will not hinder ventilation, because its sides perforated sufficiently large openings that provide a large flow of air, also, the holes in the profiles, are mounted vertically will contribute to a greater ventilation of the space under the decorative material that, in comparison with metal and wood undeniable advantage.

Although widespread due to the novelty of the polymer crate has not yet received, the successful application examples already exist.

Gecnjnf

How to install the polymer system? Does it easier and, consequently, whether the whole structure comes out strong? Never seen on the forum of any pictures polymer crates. I have the feeling that nobody it does not.

We cooperate with a construction company (build karkasniki). Their installers once tasted polymer subsystem, completely turned to her. Nothing else is no longer used. Yes, a little more expensive, but much more convenient. Especially under Blockhouse or vinyl siding.

Polymer lathing - real alternative to wooden and metal subsystems in the device with a ventilated facade cladding or siding panels.

In one of the previous material - more of ventilated facades. The subsystem is needed not only for polymer siding and facade panels, but also for concrete tile. In the video - specialist will tell you how to choose the facade.
