What types of external wall insulation boards are there?
Exterior wall insulation board also refers to the building materials used to help the external wall insulation of buildings. It is made of composite materials such as heat preservation, waterproof and decorative functions. External wall insulation boards are generally produced in factories and bonded on site. They are mainly used for high-rise external walls, indoor shopping malls, industrial equipment, basement roof insulation, non-external wall thermal insulation walls, thermal bridge parts, external walls. Construction requirements for thermal insulation composite decorative panels, etc. The types of external wall insulation boards are mainly divided into the following categories:
1. Polyurethane exterior wall insulation board
It has the characteristics of high cutting precision, fine foam, uniform cell, light bulk density, high compressive strength, convenient quality inspection, and the thickness can be produced and processed according to user requirements. In addition, the polyurethane exterior wall insulation board mainly includes: rock wool insulation board, phenolic insulation board, insulation and decoration integrated board, EPS insulation board, STP insulation board, etc.
2. External wall thermal insulation rock wool composite board
The external wall thermal insulation rock wool composite board is a new type of external wall thermal insulation material which is composed of magnesite fireproof board as the surface layer and rock wool as the core layer. It has no combustion, no heat release and toxic fumes, excellent fire resistance, good thermal insulation performance, high compression resistance, high tensile strength, good durability, no moisture absorption, aging resistance, long-term stable performance, light weight, and cuttable. Can be sawed, easy to process and so on.
3. Cement foam insulation board
Cement foam insulation board is a wall-celled rigid foam plastic made of scientific formula from various substances such as cement, fly ash, flame retardant, foaming agent and other additives. It has the characteristics of excellent fireproof performance, excellent thermal insulation performance, anti-corrosion and anti-aging, low density, light weight and environmental protection.
4. Magnesium foam external wall insulation board
The magnesite foamed exterior wall insulation board is composed of foamed magnesium cement and EPS particles. It has the excellent fire resistance of magnesite cement and the good thermal insulation properties of EPS particles. It has the characteristics of energy saving and environmental protection, good aging resistance, good sound insulation, good fire resistance and good frost resistance.
