Metal siding under a log: step-by-step installation instructions

Metal siding is a relatively new facade finishing product in comparison with traditional materials, which quickly gained popularity in the domestic market. Metal siding under a log has a polymer coating "imitating wood", which, while maintaining all the aesthetic characteristics of this natural material, is much more durable than ordinary wood, does not rot, does not scratch and does not require regular maintenance.

The facade on which the metal blockhouse is mounted looks like a wall built of rounded logs. In addition to the fact that this building material enjoys a well-deserved love among private developers, in recent years, builders have appreciated it for all its unique characteristics. Metal siding is distinguished by unique performance properties, quick assembly, long service life up to half a century.

When choosing metal siding under a log

About a cozy home from a real log house many dream. However, the majority still choose the latest generation building materials. They are more functional, practical, with them the construction process goes faster. Sheathing under a log will turn a house from any building material - from foam blocks, brick into a beautiful and cozy log house. A metal siding house is much easier to maintain than a wooden one.

Natural wood requires constant regular care - it must be impregnated with antiseptics, treated with water repellents, and painted from time to time. Siding does not need this, except to wash it from dust and dirt a couple of times a year. In addition, metal siding is maintainable. If one panel is damaged, it can be pulled out and replaced.

The area of ​​application of log metal siding is extensive.

It is used in the decoration of numerous buildings: shops, houses, dachas, cottages, cafes, tourist centers, recreation centers, etc. Metal cladding under a log can also be used for the reconstruction of already built buildings, for example, those of historical value.

Features of the material

The raw material for the manufacture of metal siding is high-quality galvanized sheet metal (made by modern rolling), covered on top with a polymer coating, which can be applied with a wood texture in shades from white and lightest (eg pine) to dark (eg oak). The peculiarity of siding is the absolute imitation of the wall surface under the log wall. Today, you can choose siding with a rough (like natural wood), textured or smooth surface (budget option).

If we look at this amazing material in layers, the picture will look like this way:

  • outside coating - polyester or polyurethane;
  • primer;
  • zinc coating;
  • cold-rolled steel sheet from 0. 45 to 0.5 mm;
  • zinc-plated again;
  • chrome-plated;
  • polyester inside.

The strength and durability of the coating depends on its thickness: the thicker it is, the more reliable it is. The 35 micron coating is more durable and has many design advantages in contrast to 25 microns.

The multi-layer coating consists of layers:

  • base;
  • decorative with a pattern;
  • protective transparent.

This coverage is designed for several decades of service. Its resistance to atmospheric and mechanical influences has been verified by numerous tests. When finishing the facade with metal siding under a log, buyers receive an excellent architectural design that does not require special maintenance.

Attention : Some manufacturers set up the production of siding with a ready-made layer of insulation.

Such products are undoubtedly more expensive, but they have their own benefits and advantages due to the absence of the need to insulate the wall of the house under the cladding. This saves labor costs and speeds up work time.

Before choosing siding for facade decoration, some people think about the preference of vinyl siding over metal. The main role is played by the price: vinyl is significantly cheaper than metal. As for other characteristics, for comparison they are presented in the table:

Table 1 - Comparison of the characteristics of metal siding and vinyl siding.

Characteristics Vinyl siding Metal siding
Installation restrictions Installation is only possible at temperatures from -5 degrees to +25 Installation is possible in any season
Operating temperature -50 ° С to +50 ° С -50 ° С to +80 ° С
Fire safety not flammable, but begins to melt quickly not flammable, but may begin to deform with prolonged exposure to extremely high temperatures
Sensitivity to humidity absent, but may mold appears absent, with correct installation rusting is excluded
Sensitivity to temperature fluctuations high: panel plays medium: compensated during installation
Sensitivity to mechanical damage high low

Advantages of the material

The following OSs can be listed Features and advantages of this material:

  1. It is lightweight and easy to install, so that when installing it does not require special equipment and lifting equipment.
  2. Has good resistance to sudden and strong temperature changes. Operated without deformation in a wide temperature range from -80 to +180 degrees .
  3. Resistant to corrosive processes resulting from exposure to rain, hail, snow, UV radiation, corrosive substances in the air as a result of poor ecology, exhaust gases, etc. The durability of the material is achieved due to multi-stage zinc and polymer treatment.

    powder formulations.

  4. Has no appreciable thermal expansion.
  5. Fireproof. The cladding prevents the spread of flame and protects the frame of the house from fire.
  6. Plays the role of a screen that prevents electromagnetic radiation from entering the house.

  7. Resistant to mechanical stress and physical factors.
  8. An additional insulation layer can be laid between the frame and the metal siding to increase the thermal insulation characteristics.
  9. The metal siding facade does not completely cover the walls, facilitating air exchange.
  10. Attractive in terms of decorativeness.
  11. The metal siding facade is perfectly combined with any roofs - with flexible tiles, with metal tiles and even with a rebate.

  12. Environmentally friendly (does not harm the environment during operation and is available for recycling after becoming unusable).
  13. Durable. metal siding without loss of technical characteristics can last up to half a century. At the same time, the cladding does not need re-painting and other types of processing.

What other features of metal siding can be noted.

Compared to natural wood cladding, it lasts for decades and does not need constant maintenance. The coating does not lose its color brightness even after prolonged use under the direct influence of atmospheric precipitation and directed UV rays. As for the objections of skeptics that the metal panel can rust, after the installation of the metal siding, all the edges are covered with slats and moisture does not get there.

Dimensions and price

On the market of modern building materials, metal siding is presented in a very wide range of colors, thanks to which it can be used to implement any design solutions. Geometrically, the dimensions and thickness of the metal from which the siding is made can vary.

Woodstock produced by MetalProfile is distinguished by a greater convexity, that is, a larger bending radius than the same one from GrandLine. A blockhouse made by different factories does not fit due to dimensional discrepancy and structural differences in the hinge bends. Unlike, for example, a ship's board, components from different manufacturers also usually do not correspond to foreign panels. Therefore, if you need to purchase additional material, you need to look for products from the manufacturer originally purchased.

Different factories even differ in the appearance of the panels.

For example, a blockhouse can simulate a single or double log, and the dimensions of the panel change accordingly.Structurally, a blockhouse for a log is a sheet of metal curved outward with a certain radius. Oval holes are punched on the upper bar of such a panel for the subsequent fastening of self-tapping screws. There is a lock on the lower bar that engages with the lower bar of the already fixed panel. The length of the panels varies from half a meter to 6 meters.

The most convenient size for transportation is considered to be 3-4 meters.

Attention : When buying metal siding, you need to check with the seller for the full and useful width. Full is considered taking into account the precast strip, useful - the distance when assembled.

The warranty period and the price of siding depend on several factors: the thickness of the metal sheet (0.45 mm or 0.

5 mm), the presence of galvanizing, the type of coating. The drawing is usually applied using photo-offset printing technology. It is important to note that this type of metal siding belongs to premium finishing building materials, so it is difficult to call it cheap. The price for a blockhouse square will invariably be higher than, for example, a ship's board due to the need to use more technologically sophisticated equipment. Therefore, imitation under a log is mainly used in the decoration of private cottages and country houses.

Construction organizations, on the other hand, prefer a more affordable shipboard.

Installation of metal siding under a log

Metal siding under a log is usually installed at the very end of construction work or even when the house is already inhabited. In any case, the house has already shrunk, windows and doors have been inserted, the roof has been made. However, manufacturers are not standing still and today it is already possible to buy metal siding with improved locks that allow the panels to move relative to each other, which is important when sheathing houses that have not yet shrunk.

Initially, a person interested in buying siding can contact the manufacturer's company or the seller, if he provides such services and provide materials on the size and configuration of the facade, which is planned to be finished with siding.

The company's engineers will calculate the lengths of the panels, as well as the number, configurations and names of components in a special computer program. Then, within 2-3 days, the panels are cut to the size of the facade.

However, if you wish, you can calculate the amount of siding yourself. When determining the area of ​​the walls, subtract the areas of doors and windows. This determines the area in need of cladding.

Now the area of ​​the panel that you plan to buy is determined: its length is multiplied by its width. Dividing the total summed area of ​​all walls by the area of ​​the panel, we get the number of slabs required for facing. It is imperative to add another 3-7% to the result obtained, since hardly applicable waste will necessarily appear.

For installation, you will need the following components:

  • starting strips from which the installation begins;
  • finishing strips for masking the joint between the panels and the cornice;
  • connecting strips covering the joints between the panels;
  • external and internal corners;
  • near-window fascia strips;
  • drips to protect plinths from running water;
  • extras.

With the help of extensions, you can give the cladding a harmonious finished look and hide the gaps that inevitably appear when finishing facades with complex configurations.

Additional elements not only decorate the seams between panels, joints in the corners and at the junction of walls and roofs, but also protect building structures from moisture, dirt, dust at the joints of the panels, extending the life of the walls of the house.

Complements for metal siding

Complements are made of the same alloy as the panels themselves. They have similar corrosion resistance to atmospheric and mechanical stress. They calculate the number of additions or specialists when ordering, or you can use a special online calculator.

The purchased metal siding is covered with a special film on the front side to avoid damage during transportation.

Before starting the installation, the panels must lie down for 48 hours. Then the film must be removed before starting installation activities. If the siding is stored in an open place, it is recommended to remove the film immediately after completion of transportation. The fact is that it can bake to the panel under the influence of ultraviolet radiation.

Preparatory work and installation of the battens

First it is necessary clean the wall from old layers of paint or other coatings.

Additionally, along the perimeter of the house, it is necessary to clear the area from everything that may interfere with installation: saw off tree branches, remove decorative and lighting elements. Roller shutters and gutters should be dismantled.

Attention : The verticality of the walls is determined using the building level - if the difference is less than 2 cm per 10 running meters and the house does not need insulation, the crate can be omitted. Small differences are simply evened out by the metal siding itself.

Metal siding under a log is attached to the crate.

The lathing is mounted from wooden blocks measuring 40 by 40 mm or from a metal profile with a step of 40-60 cm. With an object height up to 10 m, the lathing is made on straight suspensions or reinforced with corners and brackets. Installation of the lathing is done with marking. First, it is measured where the profiles will lie and the marking is made with a marker.

Then the corner contour profiles are inserted.

The supporting profile is fixed at the level with a step of 40-60 cm. The battens are fastened vertically. There must be a gap of 15 mm or more between the wall and the battens. Bars are installed along the borders of window and door openings. This will be the basis for the insulation.

Thermal insulation materials can be laid horizontally, vertically or crosswise. Dowels are used for concrete and brick walls, self-tapping screws for wooden ones.

Scheme of mounting a facade made of metal siding

You can purchase a special subsystem made of metal with a thickness of 0 for siding installation , 9 mm. It consists of L-shaped profiles, which are bolted to the brackets. The bracket is attached to the wall.

This construction will firmly hold the metal siding. A ready-made installation system is preferable to a homemade wooden one, since the tree can begin to rot under the siding or dry out over time. Likewise, the profile for drywall, which was originally used only for interior premises, is not intended for installation of siding. Another plus of the metal lathing is the ability to level the uneven wall.

Mounting on brackets

Step-by-step construction of the metal crate:

  1. Since walls tend to conduct steam, a vapor barrier is pre-attached to the walls.

    The overlap of the sheets should be 100-150 mm.

  2. When attaching a metal lathing, brackets are first attached with a pitch of 40-60 cm. Under the brackets, rubber or foamed polyethylene pads must be placed to avoid cold bridges.
  3. Next, the insulation is installed (you first need to calculate the heat loss of the building). The insulation is fastened with special dowels with a fungus - up to 5 fungi are consumed per sheet (in the corners and in the center), you can additionally fix it with a rail in the center so that it does not slip.

    When choosing a heater, you should look at the moisture absorption coefficient, which should be as small as possible.

  4. A cold-bent corner up to one and a half millimeters thick is attached to the brackets.
  5. A windproof film is stretched over the corner.
  6. A hat profile is attached to the corner, which is rigid enough to hold the entire system. The hat profile, due to the depth, allows metal siding to breathe.

    That is, the resulting condensate will be removed from the system by the air flow. Instead of a hat profile, you can use an L-shaped corner made of galvanized steel.

  7. The finished lathing is checked with a level or plumb line and adjusted if necessary.

Installation of metal siding under a log: step-by-step instructions

A certain set of tools is required to fasten the metal siding:

  • screwdriver;
  • hammer drill;
  • laser level, plumb line and wooden square;
  • mallet;
  • brush;
  • Tape measure with fabric strip;
  • metal scissors for trimming panels;
  • pliers.

Sheathing a house with metal siding under a log can be done both in the horizontal direction and in the vertical direction. This decision is made solely based on the visual effect. If the owner of the house wants the building to appear higher, the metal siding is mounted vertically, lower - in the horizontal direction.

The ease of installation of siding lies in the fact that no special building skills are required for its implementation. First, the initial bar is taken and screwed in level to the subsystem or to the crate with self-tapping screws with a galvanized press washer or with a rubber seal that will prevent moisture from entering the system.

Then the corners are set. Then the siding strip is taken and put on the bottom edge of the starting strip and screwed through the perforated hole to the batten. The next bar also hooks onto the bottom panel. Installation must be done from bottom to top. Thus, the wall is set to the very top.

Each punk is tested by level. the last panel is fixed with a finishing strip.

The following installation rules can be listed. First of all, additional elements are installed:

  1. The starting bar is installed 4 cm above the planned level of the panels at the laser level. The subsequent bar is installed every 6 mm from the previous one for ease of use.

    Fastening step - 30-40 cm .

  2. If siding is installed over a plinth, a drain bar will be required.
  3. Corner bars should be 6 mm below the starting point. They are fixed directly on the crate, with a step 20-30 cm .
  4. The docking strip is placed after marking the joints.

    Its upper edges should be placed on the top mark of the last panel, and the lower ones should protrude 6 mm below the initial one. The bar is fastened after checking the level of its perpendicularity with a step 20-30 cm .

  5. Planks are installed around the openings of windows and doors with a step of 30 cm . To make the corner joints, ears are cut out on them, which can then be bent down.

Step 4. Fastening is performed in each batten with a step of the batten.

When installing additional elements, a gap of 5 mm to 10 mm is also left to prevent panel deformation during heating / cooling.

Securing the panel with self-tapping screws

If you do not plan to use additional elements, the panels can be overlapped. To do this, you will need to cut the lock from one panel. The overlap must be 25 mm.

Installing subsequent panels

If you need to cut panels, you must use a hacksaw or metal scissors.

You cannot use an angle grinder with an abrasive wheel and a grinder for these purposes - heating of the panel contributes to the destruction of the zinc layer and over time it will begin to rust faster. However, this can be avoided by immediately covering the cut with anti-corrosion paint. You need to start cutting from the edges of the perforation for greater cutting accuracy.

When working with metal siding, heavy work gloves should be worn to avoid injuring your hands. Also wear safety glasses when cutting panels and working with loose insulation.

The process of installing metal siding

Thus, it is quite simple to install metal siding under a log with your own hands. Of course, if the length of the panels is 4-6 meters , it is better to enlist the help of an assistant who will hold the panels during their fastening.


After installation, the cladding does not need any complicated maintenance. The material is resistant to any external influences. Even if dirt gets on the siding, it can be easily cleaned with the pressure of water from the garden hose.

Result of metal siding under a log

For the future, in case of damage to the outer coating, so as not to disassemble system for replacing a pair of panels, you can immediately purchase a repair paint to cover metal siding. The repair paint can be sold in containers of 100 gr, 200 gr, 1 l.

It is designed to paint over the cut and minor scratches. You can apply this paint with a cotton swab or a match. The advantage of the special paint is that it adheres especially well to galvanizing and has excellent UV resistance.
