We insulate the attic in a private frame house with our own hands cheaply: Review + Video Thermal insulation of the attic in private frame houses is a responsible and important task that requires characteristic skills and knowledge. Today there is a huge amount of building materials for insulation. In addition, you must understand that choosing a certain type of insulation, it will be associated with the characteristic features of the attic design and is selected individually.

Types of insulation and selection criteria

We insulate the attic in a private frame house with our own hands cheaply: Review + Video Note that each insulation material has its pros and cons. The choice of insulation is often associated with a complex, that is, a certain balance between the pros and cons of the material.

When choosing a heater, you should pay attention to such criteria as:

  • vapor and moisture permeability;
  • heat conductivity;
  • safety and environmental friendliness of the material;
  • the use of construction equipment for the application of this material;
  • price ratio.

Currently, the following heat-insulating building materials are used to insulate the attic in the house:

  • foam plates;
  • mineral wool;
  • ecological wool;
  • polyurethane foam boards;
  • expanded clay slabs;
  • sawdust;
  • straw;
  • clay ...

The use of expanded clay for insulating a cold attic room

We insulate the attic in a private frame house with our own hands cheaply: Review + Video Insulation of an attic in a private house with expanded clay is used in the case of insulation of its floor covering.

It will be difficult to insulate the roof with this material due to its high flowability, but expanded clay is ideal for the attic. The insignificant weight of this material will not create any additional load on the floors.

Since this material is hydrophobic, a vapor barrier should be laid before installing it to prevent steam from escaping from the lower rooms.

For high-quality and reliable filling of all voids with expanded clay, it is necessary to use granules of different sizes. After that, it is necessary to lay the concrete mixture to form the floor screed.

After that. as the screed dries, the base of the floor is placed on it - it can be linoleum, wooden parquet or other planned building material.

Use of foam for thermal insulation of the attic space

We insulate the attic in a private frame house with our own hands cheaply: Review + Video Thermal insulation and Attic insulation with foam has both positive and negative sides. Although, the disadvantages of this material can be reduced by using the correct laying technology. T.

because when insulating the attic room with foam, you need to remember that when heated, it emits very harmful vapors - styrenes . And when insulating the roof and attic with foam, think about high-quality ventilation in advance.

If the attic of a wooden house is not residential, then one insulation layer will be enough for the roof. For residential attic spaces, foam is used in several layers.The first layer is mounted in the rafter openings, where the material will be held due to its elasticity.

The second layer is installed perpendicular to the first one and fixed to the rafters with screws or dowels.

For the second layer, foam plates with a stepped edge are used. It enables the building material to be laid seamlessly and does not allow air to pass outside.

Mineral wool as insulation for the attic

Cotton wool for the attic of the house

Consider several options for mineral wool:

  • stone wool;
  • glass wool;
  • slag wool.

Stone wool includes the best synthesis of the qualities and properties of glass wool and slag wool.

Slag wool does not have sufficient elasticity, and glass wool consists mainly of pointed particles that will irritate the respiratory system and the surface of the human skin.

Today, stone wool is the most popular - it has excellent elasticity and, with small volumes of installation, does not require any personal protective equipment . Glass wool is used in construction almost as well as stone wool, it has good elasticity, but when working with it, protective equipment is needed.

There are two main formats for producing mineral wool - mats and slabs. Packages with cotton wool have two-digit numbers indicating the density of the building material.

Do-it-yourself insulation of the attic with mineral wool will not cause much difficulty. With a roof slope of up to 45 °, medium density wool is perfect. The thickness of the insulation layer for these roofs usually coincides with the total thickness of the rafters. With a roof slope of more than 45 °, the attic is insulated with mineral wool from the inside. A layer of insulation is placed in the sinuses between all the rafters, while the plate is held without the help of a filing.

If mineral wool falls out, then a denser building material must be used.

The use of polyurethane foam for insulation of the attic premises

We insulate the attic in a private frame house with our own hands cheaply: Review + Video Polyurethane foam is a unique insulation material, it is seriously different from other options insulation. This material is monolithic. Has a low coefficient of thermal conductivity compared to other known insulation materials.

It must be applied by spraying.

Thanks to this technology, the layer of insulation will be vapor-tight and airtight.

Polyurethane foam is an environmentally friendly and safe material for insulation. After applying the material to the surface, it becomes very inert.

Insulation of the attic with polyurethane foam is a complex technological process due to the use of special construction equipment and the selection of appropriate components. Because of this, do-it-yourself thermal insulation of the attic with this material is very troublesome and costly.

With a sufficiently correct technology for mounting polyurethane foam, quality and reliability in use are guaranteed.

Thermal insulation with ecological wool

We insulate the attic in a private frame house with our own hands cheaply: Review + Video Thermal insulation with this building material is carried out in three main ways:

1) method of dry blowing;

2) method of wet application;

3 ) method of laying by hand.

The first two methods require a special blow molding machine and certain special devices. Laying by hand is done by hand. Although this application has a lot of disadvantages: excessive consumption of building material, high labor intensity of the working process and the quality of the required installation.



To insulate an attic in a private house with ecological cotton wool, you need to completely sew up the entire rafter system.

Do-it-yourself insulation of an attic space is a rather difficult task. Everything will depend on certain skills, abilities and your financial capabilities.
