Each house has windows and an entrance door. All these openings in the finished wooden structure slightly weaken it. To strengthen the walls, protect the door and window blocks from the destructive action of shrinkage processes, pigs are made in a wooden house. They are wooden boxes that are installed in a door or window opening. They are also called casing.
What is a piggy for?
- Piglets in a wooden house prevent the logs from moving horizontally and with respect to the vertical axis in the opening itself. This absolutely does not interfere with the shrinkage of the log house vertically.
- Relieves the load from the upper logs above the opening, which helps prevent various deformations of the frame and door blocks.
- Protects window frames and glass from pressure due to the effects of log shrinkage. In this case, the frames will remain intact, and the window will function as expected.
- Protects from gaps and cracks between the frame and logs.
- It makes the wall more stable, therefore, it is recommended that casing be done in timber houses that have stood for 2 years.
- Piglets in a wooden house can become a necessary element in the design, as well as a decorative component. For example, if you select an interesting texture and color, everyone can stylize this element of the house to their taste.
Types of pigs by type of manufacture
The piglet is made of dry wood, so it needs to be impregnated (painted). This can be done both by the construction team at the installation site, and at the production base itself. For those who do not know how to install a pigtail in a wooden house, a photo from building editions will show how to do it correctly. These products come in several forms.
- Solid pine - sawn round wood and get a carriage 100 mm thick, then dried. Next, workpieces of different lengths are made and processed to obtain the necessary profile. Piglet of this type is divided into draft, fair and exclusive.
- Compositional-glue - this type is made of edged wood with a moisture content of 9%. All knots and resin pockets of the tree are cut out, and after the workpiece, they are spliced along the width and length with microchips. The finished piglet is ground and processed on the machines, and then glued.
- Combined - risers and apex are made of solid pine, and the windowsill is made using a glue-type method.
Installation and design
Piglets in a wooden house consist of three elements: threshold, sidewall and apex. For each opening, a separate casing is made, and for its installation, screws, nails and other elements are not required. For insulation of the house, a heater is laid. A properly installed pigtail in a wooden house is very important. Prices for it will depend on the size. Therefore, it is very important to accurately measure all the casing that will be installed.
To correctly install the casing, you must first saw out the window opening (the optimal distance from the windowsill to the floor is 80-90 cm), after which a groove of 50 x 50 mm for the bar is prepared. Next, a bar is installed and flax batting is laid. Then install the windowsill, sidewalls and the tip. Now the little piggy is ready, now you can install windows. This work can be done by yourself.
