Insulation of the ceiling from the inside with penofol, polystyrene foam, expanded polystyrene, mineral wool

In those years when energy resources were cheap, residents of houses rarely thought about insulation. Today the situation has changed dramatically, and many have asked themselves the problem of how to insulate the ceiling from the inside with their own hands, as well as the floor, walls, window frames and entrance doors.

After all, a modern owner understands that heat in an apartment or house can be provided not only by an increase in the amount of gas consumed. But also by reducing heat loss, where one of the ways to reduce them is.

Where does the heat go

Before choosing what and how to insulate a house, you need to find out what, first of all, needs insulation. The picture shows where the heat evaporates in our homes.

As a rule, they try to equip the walls with heat-insulating material even during the construction or overhaul process. And the material is attached most often from the outside. But they begin to think about insulation of the ceiling in a private house much later.

Let's figure out what prevents us from insulating the ceiling and saving 20-30% of the outgoing heat?

What affects the temperature in the house

The following factors affect the temperature regime in the house:

• wind rose (determines the direction of the wind in your area);
• wind speed;
• the material from which the house is built;
• quality characteristics of double-glazed windows;
• arrangement of the heating system, and its autonomy;
• the presence of thermal insulation in the house.

And if we are not able to fight with some of them, then we are quite capable of reducing heat losses by arranging insulation. But, before you start figuring out how to insulate the ceiling from the inside, you need to understand what materials are suitable for this.

Therefore, on the agenda is the question - what types of insulation are applicable for insulation. And also a brief instruction on their installation.

Penofol insulation - availability, practicality and high technical characteristics "href =" http://pro-uteplenie.ru/organicheskie/polietilen/290-uteplitel-penofol "> Penofol insulation is usually not used. But, there are exceptions to any rule.

Advantages:

• resistance to moisture absorption;
• resistance to temperature extremes;
• reflective effect

Disadvantages:

• low compressive strength;
• requires the use of additional insulation.

Mounting

Penofol is attached to the ceiling with an adhesive solution or using a stapler. In this case, the foil side must face the interior of the room. Fastening is carried out end-to-end. And the joint is glued with aluminum tape.

The final look is shown in the photo below.

Helpful advice. If you purchased double-sided material, then you need to mount the crate before proceeding with its fastening. This is due to the absolute moisture resistance of penofol.

Styrofoam and expanded polystyrene

Specifications

The basis of the foam is a foamed polymer. Polyfoam is sold in sheets with a thickness of 20 to 100 mm. The material is characterized by an insignificant density of 15-25 kg / cm2. Sheet size - 1x0.5m or 1x1m.

Expanded polystyrene is made from styrene. It has a higher density compared to foam (35-45 kg / cm2).

But, the price of this material also differs per position. Thickness 20-50 mm. Sheet size 1x0.5m.

Advantages:

• insignificant weight;
• convenient dimensions;
• the ability to maintain geometric dimensions during the service life;
• low cost;
• high speed of installation;
• does not allow moisture to pass through;
• the estimated service life is about thirty years.

Disadvantages:

• flammability;
• without the use of a special mesh, the putty does not "lay down" on the foam.

Mounting

Installation of these materials does not require special skills and tools. The sheet is cut with an ordinary knife.

Its installation can be done in two ways:

1. Without arranging the frame

• apply an adhesive solution to the surface of the sheet;
• press the sheet to the surface and hold for several minutes;
• drill a through hole through the sheet into the ceiling;
• fix the sheet with large-headed screws, which are then sealed with aluminum tape;
• blow out the seams with foam. Required in order to eliminate possible "cold bridges" at the joints of the panels

The methods described above are used in cases where in the future the ceiling will be decorated with putty.

Helpful advice. If you tighten the polystyrene or expanded polystyrene with penofol, you get excellent insulation. Only in this case, penofol must be glued to the foam. Then you will need to equip the frame or counter battens between the foil and the finishing material.

1. With the arrangement of the frame

Note! Professionals, answering the question of how to insulate the ceiling in an apartment from the inside, recommend using this method. It is good because it is possible to install any finish on the frame - clapboard, plastic or suspended ceiling.

In this way, installation is carried out as follows:

• a frame is prepared from wooden beams or galvanized profiles;
• insulation is placed between them;
• next comes the finishing material.

Helpful advice. If you want to use penofol in this case. It should be glued onto the styrofoam / styrofoam. And be sure to attach the skewers.

Mineral wool

Specifications

Wool is a material obtained from basalt rocks melted at a high temperature.... It is available on the market in rolls and sheets. Material thickness from 20 to 200 mm. Sheet width 1200, length from 600 to 6000 mm.

Advantages:

• low hygroscopicity;
• low coefficient of thermal conductivity;
• flexibility;
• estimated service life up to 50 years;
• does not support combustion.

Disadvantages:

• the presence of formaldehyde as a binder for cotton wool fibers;
• if cotton wool absorbs water, it increases its weight and loses its insulating properties;
• relatively high cost.

Helpful advice. Insulation of the ceiling in a private house from the inside should be carried out precisely with the use of cotton wool. This is due to the fact that in a private house more heat "leaves" through the ceiling than in a multi-storey building. And the thermal conductivity coefficient of cotton wool is lower than that of polystyrene / expanded polystyrene.

Mounting

Helpful advice. If you want to place Penofol on the ceiling. Then this should be done before installing cotton wool.

The use of penofol is important if you need to insulate a concrete ceiling from the inside. Because concrete perfectly conducts heat, and penofol will help to keep it.

We considered how to implement insulation of ceilings from the inside. But, with all this, I would like to note that a significant part of the heat escapes through the windows. Therefore, the insulation of plastic windows in an apartment should remain in the field of vision of its owners.

Conclusion

So, when asked how to insulate the ceiling in a private house from the inside, we found several suitable options. In the video presented in this article, you will find additional information on this topic. Successful construction!
