Sound insulation of the ceiling with your own hands

Absence of soundproofing of a premise in the modern panel house delivers many inconveniences to living. Audibility of what is happening in the next apartment sometimes makes you doubt your isolation from what is happening. Options to create comfortable living conditions a bit: move to a private house or do zuvukoizulyatsiyu ceiling, walls and floors. Let's talk about how to fulfill the first point of the plan.

Sound insulation of the ceiling in the apartment. Cost of work in firms contractors

The easiest way is to call professional construction builders and order the performance of sound insulation. Pay for work and enjoy peace and comfort.

How much the work will cost the owner depends on the material and method of soundproofing installation:

1. Application of perforated gypsum or zeolite slabs costs on average from $ 7 to $ 40 per m2.
2. The application of mineral wool costs an average of $ 15.5 - $ 30 per 1 m.
3. The use of thermal insulation nonwovens for a suspended ceiling costs an average of $ 50 to $ 240.
4. Installation of branded acoustic ceiling from $ 180 to $ 300 per running meter.

Work on improving the ceiling is not difficult, most of the amount is charged for the material, but 30-40% of the price set by the customer goes to pay an employee.

For the economic and workman, it is not difficult to carry out all the work on the soundproofing of the apartment yourself.

Types of sound insulation

The essence of noise insulation is to create an obstructive barrier for the sound waves coming from the source, to weaken or completely neutralize them. The thickness of the barrier and the technical characteristics of the material for capture will affect the efficiency of sound absorption. Experts guarantee a noise reduction of more than 40% when using modern noise absorbers.

Insulation materials manufactured by modern manufacturers are divided into the following groups:

• Organic insulators. This is expanded polystyrene, fiberboard, chipboard, ecowool. They are used for soundproofing ancillary premises: garages, sheds, hangars, temporary shelters. Advantage: cost for 1 m2 from 1 $, constant availability on sale, ease of installation. Disadvantage: is easily combustible material.

• Extruded polyethylene foam. Advantages: Creates high sound insulation, is resistant to chemically aggressive environments, does not rot, and detects impact noise well. Enrichment with flame retardant increases the fireproof properties. For effective noise absorption enough plates with a thickness of 2-3 cm. The average price is from 1.8 $ to 2.5 $ per 1 m2.

• Inorganic insulators. Produced with the addition of components that enhance the protective properties of the material to fire, moisture, rot. These are well-known products from glass wool and stone wool. Advantages: durability, environmental friendliness, low cost, the average price per 1 m3 is 1.2 $ - 30 $, the high temperature range is from -600 to + 4000, which is much higher than the standards for residential premises. This quality allows using inorganic insulation for industrial premises, hot shops, bakeries, culinary workshops. Mineral insulators are inert to aggressive substances and media.

• Butyl rubber self-adhesive tape. Advantages: eco-friendliness, high sound-proof characteristics, elasticity, high water-repellent characteristic, long service life.

The material is selected independently, taking into account the budget, material characteristics and its safety for health.

Preparatory work. General description of the process of laying the hanging layer on the guide profiles

Consider the sound insulation of the ceiling in the house on a single-layer structure.

Begin preparation of the ceiling surface:

1. Remove the old wallpaper, rinse the old whitewash to the base of the overlap, remove the putty with a spatula with a sharp edge.
2. Check the bond strength of the putty with the base of the ceiling by tapping lightly on the old layer. Peel off the embedding, remove.
3. Emerging cracks, crevices, recesses are masked with a special sealant, and not with alabaster or starting putty. The sealant additionally isolates vibration and noise effects.
4. Measure the angles and check the ceiling area for evenness. For these purposes, the water level will be the most reliable tool. It is filled with water to the mark. Leaning against one corner, the indicator is noted, then a similar procedure is performed in the second corner. The difference in readings is marked on the wall. Each angle is checked, marks are put.

Measurements:

The length and width of the ceiling are measured. The length of T-shaped wide profiles and narrow rails is calculated. An important time for the construction of a suspended ceiling. Insulating materials have their dimensions, which should be taken into account when purchasing. First, the number of panels or elements for a suspended ceiling is calculated according to the total area, and then the amount of insulating material is calculated. According to the dimensions of the finishing material, the way of placement is determined: across or along the room.

After selecting the material, prepare the tooling and connectors according to the general list:

1. Screws, hangers, screws.
2. Guide rails - the amount determined after the measurement.
3. Adhesive preparation.
4. Drill, puncher, hand drill, screwdriver.
5. Hammer, pliers, metal scissors. Hacksaw, knife, rail, plane.
6. Stepladders, construction goats.
7. Selected noise isolator. Volume, footage or quantity determined after measurement.
8. Finishing material. The number is determined after the measurements.
9. Level, level, tape measure, pencil or dyeing lace.
10. Spatula for sealing joints, screws, corners.
11. Roller or brush for priming.
12. Mixture for shpatlevaniya.
13. Capacity for preparation of wet mix.
14. Grout with sandpaper.

All the listed tools can be replaced by improvised ones available in the farm.

Frame assembly:

1. The guide profile is installed. It is attached around the perimeter of the ceiling to the base with a dowel or a long self-tapping screw along the perimeter.
2. From the attached strip is indented over the width of the sheet drywall or other finishing material, put a mark. This marks a place for a narrow profile, which additionally strengthens the sheet.
3. Measure the procedure to the opposite wall. Check the reliability of fixing the rails and profiles manually. The main thing is to properly fix the corners in accordance with the ceiling calibration level.
4. The mounting profile is fixed to the profile with screws. Cross-section slats are leveled and fixed with straight hangers or "butterfly" suspensions.

Plasterboard sheet packing:

1. The length, width of the sheet is marked out, the excess part is cut off.
2. The sheet is applied to a stuffed frame and a screwdriver or self-tapping screws attached to the profile and slats.

Tip: fixing hinges slightly inducted into a sheet, the hardware is selected with an oxidized coating. The packing process is fast and simple.

Fixing of sheets of a hinged ceiling:

1. The first puttying layer is applied by starting, rough mixture. After drying the grout with nazhdachka is taken and the places of roughness are smoothed out.
2. The second trowel is applied with the finishing mortar. The dried layer is treated with a smoothing with emery until smoothness.

Ceiling painting:

1. When you start painting, decide on the color of the suspended ceiling.
2. Correctly chosen color scale has a positive effect on the well-being of the residents, decorates the interior, creates the appearance of volume and room in the room.
3. The choice of dye should be stopped on acrylic paints. They are developed without the addition of organic, solvents, inexpensive for the price, have a wide range of hues, easily applied with a roller or spray.

Multi-level ceiling insulation

With multi-level noise insulation, no work is performed on the ideal leveling of the ceiling surface. Sound insulation masks minor defects. The focus is on the exact installation of the profile.

For work prepare tools:

1. Rail, guide profile bars.
2. Adhesive for soundproof material. Primer for the substrate.
3. Drill, hand drill.
4. Screws, self-tapping screws.
5. Construction construction workers or stairs.
6. Pliers.
7. Scissors for metal.
8. Working gloves.
9. Safety glasses.
10. Solution tank.
11. Suspension.
12. Roller with foam rubber, length 150-180 mm.

Work process:

1. Flush the old whitewash from the ceiling, peel off the paint. Dry the surface. Close up microcracks.
2. Install on the ceiling guides with anti-vibration system.
3. Dilute the adhesive according to the enclosed instructions.
4. Pour part of the solution into the container, apply roller to the ceiling. Prepare the insulation material, cut the piece along the length of the ceiling.
5. Press the insulator against the surface and immediately clamp it with suspensions. Distribute the material with a margin of 1-2 centimeters on the walls. Align the material on the ceiling, make sure that there are no air bubbles between the ceiling and mineral wool. The edges of the next roll are butted to the pasted one.
6. Nail dowels or attach self-tapping wide T-shaped profiles, maintaining the distance between the rails equal to the width of the sheet of finishing material.
7. Fasten narrow slats to support trim sheets.
8. Push the drywall. Screw to profile rails with a screwdriver.
9. Seal joints with sealant. Shpaklyuete in 2 layers of sheets. Stain.

This insulation provides 20-25% higher protection than single-level protection.

How to make self-tension ceilings

Sound insulation of stretch ceiling is made by pulling a special cloth, fabric material based on polyester on the profiles. Visually, the design is simple, therefore, it is easier to install than from plasterboard. But each process has its own peculiarities and subtleties.

Installation of a simple tension ceiling. On the surface there are no pipes, communications, a room of strictly geometric form, without niches or protrusions. What you need to prepare for work:

1. Material: PVC film or fabric.
2. Baguette profile.
3. Centimeter, measuring tape.
4. Pencil.
5. Water level.
6. Folding protractor. Hacksaw or scissors for metal.
7. Fan heater, air heater.
8. Screwdriver.
9. Screws or dowels.

Installation of a simple tension ceiling:

1. With the water level, find the bottom corner of the room, step back 1-2 cm, make a mark.

2. Find the zero level along the perimeter of the walls, make a mark.

3. Carry out the angle measurement with a folding protractor to flatten the profile.

4. Prepare the profile rail. There are two options:

• the length of the baguette is greater than the width of the room. The edge of the rail is cut at an angle equal to half the corner of the room;
• baguette length is less than the width of the room. One end of the rail is cut into half the corner of the room, and the second is cut to 900 for an exact fit to the second rack. The missing piece of baguette is taken and the same operation is performed with its endings, with a bevel for the opposite corner. The parts of the baguette are glued together.

5. Fix the baguette around the perimeter of the wall, verify by level. Fasteners carry out self-tapping screws or dowels.

6. Turn on the heater and warm up the room to a temperature of 40 and above degrees. The windows and doors to the room are closed. Only after setting the required temperature, the PVC-based insulation material for the suspended ceiling is unwound. Avoid close contact of the insulator with the air heater. Warm up the film to 600.

7. Begin the stretching of the cloth. The base angle is marked on the film. Installation begins with it, then fix the angle diagonally. Similarly, fasten the two remaining corners. Proceed to secure the sidewalls. The fabric material is also warmed up, but the order of fastening is applied differently: first, the sidewalls are fixed, the corners - in the second turn.
