Advantages and disadvantages analysis of building external wall thermal insulation materials
Thermal insulation material of building exterior wall is an important factor affecting building energy saving. The development and application of thermal insulation materials for building exterior walls have been paid more and more attention by countries all over the world. China's building energy-saving market is huge, and the corresponding thermal insulation and energy-saving materials in the market also have their own characteristics, and a hundred flowers bloom. EPS expanded polystyrene board, XPS extruded polystyrene board, rock wool board, phenolic board, vitrified bead thermal insulation mortar, rubber powder polystyrene particle thermal insulation mortar, etc. , each has its advantages and disadvantages.
1.EPS expanded polystyrene board
Advantages: superior thermal insulation performance, mature technology, convenient construction and superior cost performance.
Disadvantages: poor fire resistance, generally B2 grade, preferably B 1 grade; Low hardness and poor impact resistance; The system is easy to crack and poor waterproof; Wet operation is greatly affected by the weather; Market chaos.
2.XPS extruded polystyrene board thin plastering external wall insulation system
Advantages: superior thermal insulation performance, mature technology, convenient construction and high cost performance.
Disadvantages: poor fire resistance, generally B2 grade, preferably only B 1 grade; Low strength and poor impact resistance; The system is easy to crack and poor waterproof; Wet operation is greatly affected by the weather; Market chaos.
3. Rock wool board
Advantages: Class A incombustible, superior thermal insulation performance, mature technology, convenient construction and good fireproof performance.
Disadvantages: high water absorption.
4. Phenolic board
Advantages: good fireproof performance, good thermal insulation performance and convenient construction.
Disadvantages: low strength and easy pulverization; Not suitable for thin plastering system.
thermal insulation glazed hollow bead mortar
Advantages: good fireproof performance, small deformation coefficient, anti-aging, stable performance, good combination with wall base, high safety and recycling.
Disadvantages: large capacity, poor heat preservation and energy saving effect.
6. Rubber powder polystyrene particle thermal insulation mortar
Advantages: Good thermal insulation and energy saving effect, easy adhesion between the thermal insulation layer and the wall, low requirement on the flatness of the base wall, simple construction technology, and no large-scale cracking, hollowing and falling off.
Disadvantages: poor fire protection performance and large capacity.
