Insulation for ventilated facade: which one is better not to spill, do not slipped and sat down
Design ventilated facade with an air gap between the insulation and finish. Each heater has its own advantages and disadvantages. Many choose Rockwool (excellent water-repellent properties), but its cost is high.
Mineral wool
This is the most used material for insulation ventilated facade.
Benefits
- Resistance to moisture. At the material has a plurality of pores. Vata great passes vapor and air. But bad wool absorbs moisture, so the room to protect from moisture.
- Moderate breathability. The material is breathable and provides a comfortable microclimate for the person in the room, so it does not require the premises to make additional ventilation. On mineral wool virtually no condensation.
- Beautiful sound insulation. Due to the existing pores in a heater in the room did not pass the sound from the street.
- The material does not burn. The building with fireproof insulation.
- Long service life.
Mineral wool can last 20-60 years. Rodents can not damage the material. Better to buy a density of at least 80 kg / m3.
Minuses
The mineral wool are harmful resins. They can be harmful to human health. These resins excel in air. But studies have shown that these resins is not enough. Although the operation of small particles can penetrate the skin and cause human allergies.
Wool loses its moisture after some period of operation. On a material appears condensation, mold and fungus. This reduces the thermal conductivity, so the use of mineral wool should use gidroizollyant.
Expanded polystyrene
Benefits
- Excellent resistance to moisture.
- Excellent thermal insulation properties.
- It does not appear fungus and mold.
- The material is light, easy to use, easy to cut and install.
- Resistant to abrupt climate change.
- It has excellent insulation against sound.
- No need to install additional waterproofing.
- It has a long service life.
Minuses
- Easily damaged mechanically, it is not durable.
- Do not miss oxygen.
- Destroyed by paint and varnish.
Polyurethane foam
Benefits
- Polyurethane foam is easy to attach to any material, such as metal and glass.
- It weighs a little.
- Well strengthens the walls.
- This is an environmentally friendly material.
- Resistant to acids and alkalis.
- Safely tolerate climate change.
- It has no joints, it is applied to whole cloth.
- Resistant to fire.
- It has excellent thermal insulation.
Minuses
- It should be protected from sunlight, since they can damage it.
- Although refractory material, but from the high temperatures it may begin to decay, then the material is cooled.
Of these materials is better to choose a polyurethane foam, as it has fewer flaws.
