Technology of insulation of attic floor

Technique for laying the thermal insulation of the

Each construction technology must be based on safety rules. Stacking insulation slabs - no exception.

Obligatory condition of overlapping is strength. A good fit can withstand heavy loads and not sag under the awning. The attic room has its own properties, one of which is the degree of deflection. It ranges from 1 to 200 construction spans. Based on this, per 1 square meter can account for up to 100 kilograms.

The attic space is often built of wood. It is important to comply with fire safety regulations and minimize the level of ignition. Houses of various materials have their own limits of fire resistance:

• Concrete structures, reinforced concrete structures have fire resistance at 1 hour;
• Ceilings from wood with plaster finishing - 3 hours;
• Overlapping of wood without a protection level - 5 minutes.

The scheme of arrangement of thermal insulation of overlap

A common type of overlap is the beam type. It is easy to install and repair. It is often used in the construction of houses made of wood. Beams made of iron and wood are used.

Wooden have properties:

• Low price;
• Easy to process;
• The presence of high heat resistance.

Heat insulation process:

1. Insulation material is placed in the gaps of the beams

   

2. In case of using short beams, they are lengthened intentionally
3. Before the flooring of the insulation is put a protective foil of the vapor barrier
4. The vapor barrier is laid in a way that allows air to be retained when moving from room to room in the attic space

Selection of overlap material

What building material is worth buying? There are types of insulation:

1. Mineral wool. It is also called basalt. Its basis - the mountain components. Has a low price and is of good quality. Produced in rolls or sheets and convenient to lay. Flooring with cotton can be done by yourself, using protective clothing from irritating effects. Before use it is necessary to lay a layer of vapor barrier.

   

2. Environmental wool. Content - cellulose and loose fibers. Does not cause allergic reactions in the handler. It is produced in bagged form. It has the appearance of loose material, it is filled up between the beams. Ecowool is fireproof. Among buyers, it causes criticism because of its high price.

   

3. Glass wool. It differs little from mineral wool. Its plus - low cost.
4. Polyfoam. Easy in the equipment, freely cut into the required lengths. The method of its flooring is characterized by high fixation( without the slightest air gaps).Any slots are eliminated by mounting foam. Has the property of causing an allergic reaction.

   

5. Backfilling. They are environmentally friendly. Composition - wood shavings and dry sheets. Does not have fire resistance.

   

The selected material for overlapping the attic space needs to be laid with one layer. The principle of laying - "pie" of two layers of thermal insulation with a shift in polkorpusa + vapor barrier. Multi-layer insulation technology will add strength and reliably keep the heat of the room.
