Building exterior insulation system

[hhmee]

Building exterior insulation system is a systematic project, involving multiple aspects of material properties, materials, wall grassroots, environment, technology, quality management, design, application, construction, etc., after years of progress and development, the industry is still widespread concern building quality thermal insulation projects, a large number of already cook wall insulation interlocking floor tiles for indoor use energy-saving projects, the ability to withstand the test of time, 10 years, 25 years, 50 years? On the current status quo of practice and quality of the project, if it continues, more and more quality problems, especially in raw material prices, product prices lower sales and project contracting market context, we should face the reality, scientific and rational selection, timber, improved technology, standardized construction, improve project quality, to be effective insulation layer interface process (only 0.8-1.0 yuan per square meter).

it is a very scientific and practical method can greatly save resources, reduce engineering costs, improve project quality. Building exterior insulation engineering major problem. Responsibility distinguish the quality of the insulation system (1) thermal insulation properties Insulation efficiency depends on the thermal insulation properties and thickness of the insulation layer of insulating material, if not 50% or up to 65%, the main problem is the insulation material. Hollowing, shedding, poor adhesion or not long-term stable mainly organic material aging mortar, mortar performance can not function properly, or interface treatment improper insulation, construction regulations fails to do so on crack, crack mortar use of raw materials improper, unreasonable formula, water transfer moisture capacity is weak, anti-shrinkage mortar problem of poor. Stability and stable life issues insulation board insulation systems have a process, I believe, its initial stability, at least one natural cold climatic cycle (one year), winter frozen.

summer sunlight, wind and frost rain and snow, which is the insulation layer constantly adapt environment and climate change, and withstood wood deck tiles clearance the test environment merciless climate, after a natural circulation of hot and cold weather naturally, there will be some changes in the insulation system. The life of the insulation system mainly depends on material and construction technology life cycles and a variety of their own materials, exterior insulation system in the external walls of the surface, on top of the insulation layer is thin plaster, environment and climate complex, temperature up nearly 100 ℃, strong ultraviolet radiation, solar radiation, acid rain, erosion, strong winds, earthquakes, and building structure changes, ground subsidence, and damage will affect the life of the insulation layer.
