Construction of a reliable floor for a modern frame house

A sturdy and long-lasting floor is a must for any contemporary frame home. A sturdy floor improves the overall comfort and usefulness of the house in addition to supporting the structure. By taking the proper measures, you can make sure that your floor will withstand normal wear and tear and serve as a strong base for the rest of the house.

The correct materials and construction techniques must be used when building a frame house’s floor. Long-lasting flooring is influenced by various elements, including load-bearing capacity, moisture control, and insulation. Making informed decisions during the building process will be made easier if you comprehend these components and their interactions.

We’ll go over the crucial procedures and factors to take into account when constructing a sturdy floor in a contemporary frame home in this article. You’ll get useful advice to help you navigate the building process and create a floor that fulfills your requirements and expectations, from material selection to common problems.

Aspect Description
Foundation Ensure a strong, level foundation to support the floor. This could be a concrete slab or a series of piers.
Joists Use high-quality, properly spaced joists to create a stable framework. They should be treated to resist pests and moisture.
Subfloor Install a durable subfloor, like plywood or OSB, securely attached to the joists. This adds strength and prevents squeaks.
Insulation Include insulation between joists to enhance energy efficiency and soundproofing. Choose appropriate materials based on climate.
Flooring Select a finish that matches your needs and style, such as hardwood, laminate, or tile. Ensure it"s compatible with the subfloor.
Moisture Control Incorporate moisture barriers to prevent dampness and potential damage. This is especially important in areas prone to high humidity.
Ventilation Ensure proper ventilation to avoid moisture buildup and improve air quality beneath the floor.

Pie designs

In a frame house, the ceiling must be made first. Concurrently, it will also function as a subfloor. It is necessary to firmly fasten the main floor beams to the grillage, or foundation frame.

It is crucial to understand that the space between metal piles and wooden beams needs to be waterproofed. It is essential for shielding elements with disparate properties from outside influences, particularly natural humidity. Roll material is applied in two layers for waterproofing. Linocrom, waterproofing, or roofing felt are some options. Old glassine or roofing felt can occasionally be discovered. Using them is not advised.

There are two methods for creating a frame house’s load-bearing floor base:

  • using main beams;
  • using main and secondary beams.

You can raise the main beams’ pitch by using simpler logs or secondary beams. However, this option results in an increase in the amount of work, the amount of material used, and the thickness of the floor.

The main beams are also utilized as logs when there are no secondary beams. This is how the correct pie appears in this instance, listed from bottom to top:

  • cranial bars with a cross section of up to 50×50 mm, which are attached to the side at the bottom of the load-bearing floor beams;
  • boarding;
  • moisture and wind protection;
  • load-bearing beams with insulation between them;
  • vapor barrier material;
  • subfloor boards or chipboard about 16 mm thick.

How to make a floor in a frame house

Consider using a beam or edged board with an average cross section of 5 by 15 cm for your floor beams. Pitch of the elements and span length determine the exact dimensions. The bigger side of the boards is installed vertically, while the smaller side is oriented horizontally. Installing it in the opposite direction significantly lowers the load-bearing capacity.

Before usage, an antiseptic must be applied to all wooden components. With the help of such a material, you can keep the floor pie in a frame house free of mold and decay. It can also be treated with fire retardants. As a result, the house will be safer and have greater fire resistance.

In a frame house, the main floor beams are constructed by hand, and at the same time, the logs are fastened to the foundation grillage on piles. Everything needs to be arranged on top. High reliability is not provided by side fastening. There are two variations: using a notch or not. A notch makes it possible to fasten the components firmly, but it also erodes the strapping. It is advised to forgo it because of this.

One type of fastening tool is the anchor bolt. The strapping fixes them in place. You will need to drill holes in the beams in order to fasten them. Lags are arranged on an anchor and hammered at the point of support for this purpose. The proper dent will continue to exist. The floors are put in place once the beam’s holes have been made, and the anchor’s nuts are then tightened over them. It’s also advised to use the washing machines. This is because soft wood can submerge a small section’s metal components.

Consolidating the skull bars comes next after the major supporting structures are put in place. These components are required in order to attach the brush boards to them. Bars are fastened to studs, screws, or nails. The masses of the insulation and binder, as well as the spacing between the supporting beams, are taken into consideration when choosing dimensions for a given load. Use bars that are 50×50 mm or smaller the most.

They create a floor using skull bars. It will act as the insulation’s foundation. Use self-tapping screws or nails for fastening. Take a 25–40 mm thick board that has been antiseptically treated for manufacturing. The backing is covered in a layer of windproof and waterproof material. The joints are taped and secured with a construction stapler. At the joints, there is a minimum overlap of 10 cm.

Modern vapor diffusion moisture-proof membranes are advised for waterproofing and wind protection. They took the place of movies. Vapor permeability is this material’s primary benefit. The membrane effectively extracts steam to the outside, shielding the insulation from moisture while allowing the house to continue "breathing."

The spaces between the load-bearing beams are insulated. It needs to have a vapor barrier to keep out interior vapor. Films or membranes are the options available here as well. The best materials should be used when constructing your house. Film will be less expensive than the membrane, though.

When the flooring is installed in a frame house, the subfloor is finished. You must leave a gap of two to three centimeters thick for ventilation between it and the insulation. Use 40 mm thick edged boards for flooring. The standard measurement for width is 100 mm. The flooring needs to be impregnated with an antiseptic, just like the other components. The joists are fastened to the boards with either self-tapping screws or nails. Selecting corrosion-resistant galvanized fasteners is essential.

Insulation of floors

For the purpose of thermally insulating floors, various materials are used. Since the insulation is positioned between the joists and does not absorb the payload, there is no restriction on strength.

Among the commonly used insulation options are:

  • mineral wool;
  • Styrofoam;
  • extruded polystyrene foam (“Penoplex”);
  • penoizol (in the form of foam).

Mineral wool has grown in popularity as a material. This is supported by the material’s affordable price, accessibility, and ease of use. Vapor permeability is another benefit; wool doesn’t obstruct the building’s natural ventilation system. It is advised to set the lag pitch so that there is a noticeable space of 580 or 1180 mm between the slabs in order to prevent having to cut them. This will make it possible for you to install the insulation firmly and cut-free.

The capacity of mineral wool to absorb moisture is one of its drawbacks. The material can no longer serve its intended purpose in this situation. A good vapor barrier and waterproofing are enough to keep the insulation dry. Check out the in-depth article on using mineral wool for floor insulation.

Mineral wool comes in various forms. Rigid slabs of basalt are ideal. Slag wool is made from industrial waste, and glass wool is inconvenient to work with.

Depending on the climate zone, a calculation is used to determine the insulation’s thickness. This will typically be in the range of 5 to 15 cm. To ensure precise computations, the TEREMOK software should be utilized. It is readily accessible as an online or desktop application in the public domain. You must choose a settlement from the list, the kind of structure to be calculated, the insulation’s thickness, and its thermal conductivity in order to perform the calculations. Finding out about the final feature from the manufacturers is simple.

For long-term stability and comfort, a modern frame house must have a sturdy and dependable floor. By using the proper building materials and techniques, you can guarantee that your floor will be able to withstand normal wear and tear and still provide a strong foundation.

Start with premium materials that are suited to the requirements of your house. Make sure your choices—whether engineered or conventional wood—meet structural specifications and are appropriate for the area’s climate.

The installation must be done correctly. Make sure the floor joists are supported and spaced appropriately. Pay attention to moisture control to avoid problems that over time can weaken the integrity of the floor, such as warping or mold.

By paying attention to these details, you can build a floor that is dependable and long-lasting, improving the overall strength and security of your frame home. Time and effort put into these little details will pay off in the form of a secure and cozy home for many years to come.

A sturdy floor is crucial for modern frame homes because it ensures both longevity and comfort. Use premium materials and appropriate construction methods that guarantee insulation and stability to accomplish this. A well-built floor improves your home’s overall livability in addition to supporting the structure.
