In this article we discuss the main types of interior walls, the easiest way of building an interior wall in your country house or your flat with your own hands, the details of construction process.
Internal walls are not only load-bearing structures but also ordinary partitions between rooms. If a question ‘how to build an interior wall’ appears, it means the end of the entire construction of an apartment or a house. Partitions that are planned to be delivered must have high performance of lightness and structural integrity, heat and vapor barrier as well. Traditionally internal walls are built of brick or wood, but it is also popular to use drywall, concrete blocks and OSB-boards nowadays. Here are some simple tips on how to build internal walls.
Interior brick walls
This type of internal walls is good to separate toilets and bathrooms. Usually masonry is made in a half-brick way (5 inches). If the duct in the wall is needed, then a wall can be thickened to about 1 foot. Laying bricks should be upward, and don’t forget about reinforcement of the wall every 5 row. Strong connection between the interior walls and adjacent walls is achieved by creation of special grooves with a depth of about 2 inches. After finishing building of interior brick wall it should be necessarily plastered which allows to get the maximum thermo insulation and sound-proofing. Interior brick walls are very stylish and they will never be out of fashion.
Interior plasterboard walls
Nowadays plasterboard is often used not only as a coating material, but also as complex and important element of the entire house – its walls, floor, stairs and so on. It can help to make the zoning area of the house. If you want to build an interior plasterboard wall, you should have the plasterboard itself, screws, metal rails and rack profiles. The process of construction begins with the mounting horizontal profiles (rails) to the floor and ceiling (using screws) which will serve to support the walls. Then at a distance of about 1,5-2 feet from each other you should insert rack profiles. The first rack is mounted to the support of the existing wall, and all the rest are mount to the horizontal rails on the ceiling and the floor. Joints of plasterboard sheets must necessarily be in the middle of the profile for the possibility of attaching them to the frame. Such design will help to put the necessary sound insulation materials to the gap.
Interior stud walls
The stud structure is very popular now. It is the cheapest option for interior walls of the house. Its construction does not require special knowledge and skills, knowing of some professional secrets. The process will need studs with the section of 2*3 inches, binding for the top and the bottom, sheathing and insulation materials.
To get started first prepare the material. Before installation you need to stock up guides and bars for studs, the height of them is determined on the height of the room without taking into account the thickness of the top metal guide profile. Then one bar is hammered to the floor. You should mark positions of future pillars on it, at intervals of about 2 feet, and then hammer the second bar to the ceiling. The next step is the installation of racks in the upright position which can be easily made using a level. And the last step is mounting spacers and trimming the resulting frame with filling its with necessary insulation materials.
Decorating interior walls
Plaster is a mixture made of various kinds of substrates. Different types of plaster suit to different materials walls made of. For example, for gypsum walls it is better to use mixture of lime and gypsum plaster, or pure one. Brick and concrete suit perfectly to sand-cement, cement-lime, lime, pure cement mixtures. There are different types of plaster. The most popular type is the invoice plaster. It is applied with a trowel. A layer of plaster on a wall should not exceed 2 inches. The application starts from the corner of the wall near the ceiling.
The most popular method of decoration internal walls is wallpapering. There are variety of wallpaper colors, textures, shapes and sizes. Don’t forget that when you buy a wallpaper glue it should match exactly the kind of wallpaper you have! Pasting the first band should be strictly vertical. Wallpaper glue should stay in a closed room with no draft for the first night.
Of course, you can use your imagination and decorate your internal walls in non-traditional way. You can paint a picture on it (yourself, or you invite a professional artist), use different flower pots.
Here are some most important rules on how to build an interior wall with door :
- crop the stud profile for height and insert it into the guiding one;
- the width of the doorway at the top and at the bottom must be the same;
- check the verticality of studs with a level.
We hope that this tips on how to build an internal wall will help you with your house construction!
Q&A related to building the interior walls
Question: Are there any special requirements for the material used to build the interior walls of the house?
Answer: Of course, there is a difference in technical requirements for exterior (load-bearing) walls and interior walls. When building an internal wall in the house, the following criteria should be adhered to:
- Good performance of heat and sound insulation. From these parameters will depend on the level of comfort both inside and outside the room.
- Durability. The sturdier your walls will be, the longer they will naturally be able to serve you.
- Dimensions. The dimensions of the products determine the speed of subsequent work.
- Composition of the material. On this parameter depends the level of safety for health during operation.
- The degree of vapor permeability. This figure indicates how well the material passes vapor through itself. If vapor permeability will be too low, you will have to install ventilation.
- Ease of installation. It is desirable to choose a material that you will be able to install.
Question: How do I achieve good soundproofing of an interior wall?
Answer: Yes, an important requirement for a new wall is soundproofing capacity. The minimum airborne noise isolation index Rw is 43 dB. That is, quiet speech should not be heard from behind them. The Rw index of a plastered wall that is half brick thick from both sides is 47 dB, the Rw index of a foam brick wall that is 7,8 pieces thick is 44 dB. But in practice it usually aims to make it thinner. In this case the plasterboard cladding on purlins, between the studs which have sound-absorbing mats, providing additional sound insulation up to 10 dB will help.
Question: What is the optimum thickness of interior walls?
Answer: Indoors, the thickness of partition walls made of bricks ranges from 4.7 to 25 in – an impressive parameter that should be chosen carefully. Thick structures are used mainly for the construction of load-bearing walls, as well as exterior facades.
Inside the house, masonry of 0.5 bricks with a thickness of 4.7 in is often used – it is effective and inexpensive, but may require additional material for soundproofing. Sometimes use a special method of construction “on the rib” that is, a brick put the smallest side, resulting in a width of the wall is 2.8 in. Such masonry does not give reliability, there is almost no saving of space and material, so for interior dividers, experts recommend the option of 0.5 building material.
