What material is better for roof insulation?

In hot summer, the temperature on the roof is extremely high, which seriously affects people's life and mood. Many families will choose roof insulation, and how to insulate is a problem that everyone needs to think about. So what insulation material should be used? Is it better to use wood or film? Owners who don't know yet have a look at the following introduction.

Roof insulation method

1, air circulation heat insulation method: cover the roof with a hollow interlayer of about 30cm. When the sun is exposed, there is flowing air under the roof, which can effectively isolate indoor heat transfer.

2. Water insulation method: This method is a kind of insulation method that many residents like to use. The roof is usually a shallow water pit with a depth of about 15cm, which can effectively and reasonably reduce the indoor temperature. It is relatively simple, but it requires high quality of the roof.

3. White paper reflection method: that is, spread a layer of white paper (tin foil) with smooth surface on the roof, which is not easy to get oil, has strong reflection and heat insulation.

4. At present, there are many methods for roof insulation. You can lay 10 cm thick pearl sand insulation layer on the roof, and then make a layer of cement prefabricated insulation board. If it is a cast-in-place reinforced concrete roof, a soil layer with a thickness of 20 cm can be stored on it for greening and planting flowers and plants, which not only beautifies the harsh environment, but also has the function of thermal insulation.

5. Roof heat insulation method The invention discloses a roof leak-proof heat insulation method, which covers the whole roof with glass steel plates and bonds the glass steel plates into a whole.

Compared with the prior art, it has the advantages of easy construction, high material strength, light self-weight, long service life, good leak-proof and heat insulation effect, etc.

6. If the top users adopt the method of laying ceramsite concrete for thermal insulation, the indoor temperature can be greatly reduced, which can not only lead a comfortable summer, but also effectively save electricity and reduce the expenditure of electricity. As a roof insulation layer, ceramsite concrete has good moisture-proof and waterproof effects, and is effective in thermal insulation. Now ceramsite concrete has been widely used as toilet backfill and roof insulation layer.

Roof insulation material

1, thermal insulation gauze

At present, it is sold in the market, and the price is relatively not very expensive, a few dollars a meter or so. Thermal insulation gauze is mainly made of nylon, which can reflect sunlight after chemical treatment, thus reducing the direct contact between roofs. This method is favored by many consumers because of its good effect, relatively affordable and relatively simple use.

2. Heat insulation board

These plates are made of special materials and have good heat insulation effect. The main color of the board is white, because white has a good reflective effect, so that after the sun shines, it can reflect the sun well, and then it can play a role in heat insulation.

3. Dike aluminum foil insulation coil

It is made of aluminum foil veneer+polyethylene film+fiber braid+metal coating laminated by hot melt adhesive, which has the functions of heat insulation, waterproof and moisture prevention. Aluminum foil thermal insulation coiled material has extremely low solar absorption coefficient (solar radiation absorption coefficient) (0.07) and excellent thermal insulation performance, which can reflect more than 93% of radiant heat, and is widely used in building roofs and external walls.

Common thermal insulation materials

1, expanded polystyrene board for EPS board, thermal conductivity of 0.038-0.04 1, good thermal insulation effect, low price, but slightly poor strength;

2. XPS board of extruded polystyrene board, with thermal conductivity of 0.028-0.03, has good thermal insulation effect, high strength and moisture resistance, but it is expensive and needs surface treatment during construction;

3. Rock wool board, with thermal conductivity of 0.04 1-0.045, is fireproof, flame retardant and hygroscopic, but its thermal insulation effect is not as good as the first two materials;

4. Rubber powder polystyrene particle thermal insulation slurry, with thermal conductivity of 0.057-0.06, recycled waste, good flame retardancy, but unsatisfactory thermal insulation effect and high construction requirements;

5. Polyurethane foam material, with thermal conductivity of 0.025-0.028, has good water resistance, good thermal insulation effect and high strength, but it is more expensive.

6, perlite, etc. , thermal conductivity of 0.07-0.09, good waterproof, high temperature resistance, poor guarantee effect.

The above is an introduction to the knowledge of roof insulation. The partition layer of modern houses is generally thin, so it is very necessary to treat the roof insulation in summer. What materials are used for personal insulation of the roof? I would like to introduce them to you here, hoping to help the owners.
