# The distance between the racks in the frame house is necessary for the insulation: Review + Video

When designing a frame structure, house or outbuildings, the question arises, what is the distance between the floor beams in a frame house ...

The distance between the posts of the frame house in this case is chosen by the developer based on the size of the sheets of plywood or starting from the width of the insulation provided in the frame. Which option will be correct, we will consider in this article.

Also, do not forget that the deformation gap, the device of which is necessary between the sheets of the outer skin, should also be determined.

Thus, the three main questions that arise in the process of designing a timber frame house are as follows:

1. What distance should be planned between the floor beams in a frame house ?
2. What material width should be guided by when choosing (plywood, OSB, insulation)?
3. What should be the deformation gap?

Let's try to understand this issue.

## What determines the distance between the racks of a frame house for insulation

The distance of racks in a frame house should be planned based on the orientation to several basic indicators.

A comprehensive solution to this issue requires taking into account:

• dimensions of plywood sheets or OSB sheets with which it is planned to sheathe the frame of the house,
• sizes and type the insulation chosen for the organization of thermal insulation of the frame structure,
• how the premises and the upper strapping in the frame house will be finished.

Taking into account all these components will help to make the best use of materials and make it possible to minimize waste, which means it will help save finances.

In addition, this approach is aimed at finding opportunities to minimize the time and labor costs when building a house using frame technology.

We can say that when starting to determine the pitch of the racks, you should first imagine how you plan to make the "pie" of the frame wall itself, this also requires reliability, like floor logs.

### We calculate the distance between the posts in the frame house

Let's consider the main calculation options.

1. If the walls are planned to be erected and made of such building materials as gypsum plasterboard and OSB, and a cotton filler (ecowool, glass wool, etc.) is chosen as a heater, then the step of the racks will be calculated based on the overall dimensions of drywall or OSB.

Cotton filler is quite plastic and its dimensions are not important in this case.

However, in this case we use two cladding materials - drywall and OSB. What is the distance between the racks in the frame house to choose and the dimensions of which of these materials should you focus on? In this case, it is advised to focus on the size of the drywall sheets, while the OSB plates will have to be cut taking into account the deformation gap.

1. In the event that more solid non-plastic materials are used for insulation, for example, basalt insulation, and the external and internal finishes are made of OSB foxes and lining, respectively, then the distance between the posts of the frame house will be calculated with orientation to the size of oriented strand board and insulation. Considering the deformation strip of the basalt slab, which is 50 mm.

, the spacing between the uprights will vary with a 50mm gap.

The length of the lining, as a rule, does not affect the distance between the posts, since this cladding material can be attached to an additional wooden lathing specially arranged for it.

1. Insulating a frame house with foam when calculating the step will require focusing on the dimensions of the building material, since trimming foam blocks can be a rather dreary and uneconomical work.

It should be taken into account that foam sheets tend to shrink and, within six months after installation, lose about 1% of their original size.

#### Foam sheets can be fastened in two ways

• In the first case, fixing the insulation involves installing the sheets in such a way that they are tight enough to touch each other and do not form gaps.

So, even after shrinkage, no distance (cold bridges) is formed between the foam plates, which means that the insulation will be more effective. This method requires a certain amount of experience and accuracy.

• The second method allows the installation of foam sheets with an opening along the entire perimeter of up to 10 mm. The resulting cracks are filled with polyurethane foam. The ten-millimeter gap is indicated for a reason.

Slots less than 5 mm. it is quite problematic to insulate with polyurethane foam, because the nose of the foam gun will not crawl through them. And the gap is more than 10 mm. several times increases the consumption of polyurethane foam.

##### The frame of the boards

The frame of the house from the boards requires a different approach in the calculations.

In this case, regardless of the chosen type of finish and insulation, the distance between the posts will directly depend on the dimensions of the board used.

So the pitch between boards 50x150 mm, used as supports, should not exceed 650 mm. If a board of 50x100 mm is used. - the maximum distance of the supports will be 400 mm.

Therefore, there are several factors to consider when calculating the pitch.

The distance between the posts of a frame house will depend on the insulation used, the chosen cladding, and even on what the posts themselves are supposed to be made of.
