In the development of modern society, the level of science and technology and economic level have improved significantly, which has brought earth-shaking changes to people's lives. At the same time, energy consumption is also increasing, leading to energy crisis. According to relevant data. The energy consumption of construction industry is much higher than that of other industries, which has caused serious damage to the ecological environment. In order to reduce building energy consumption, we have adopted a large number of new energy-saving materials and new technologies, which on the one hand achieve the purpose of energy saving and improve the social and economic benefits of the building, on the other hand can reduce the impact on the ecological environment and make the project have ecological benefits. At present, with the continuous improvement of people's awareness of environmental protection, more and more attention has been paid to building energy conservation and environmental protection. In this paper, the energy-saving thermal insulation and waterproof technology of building roof is comprehensively analyzed.

First, the necessity of building roof energy saving

The rapid development of society puts forward higher requirements for energy demand. The greater the amount of development and use, the faster the energy reduction and the more serious the energy crisis. China's current resource situation is also facing the problem of shortage. How to reduce energy consumption and achieve greater energy-saving effect has become a problem that must be considered in the development of every industry. As a major energy consumer, it is an inevitable trend for the construction industry to realize the development of building energy conservation. First of all, building energy conservation can reduce the carbon dioxide emissions caused by building use, reduce the greenhouse effect, protect the ecological environment, and realize energy conservation and emission reduction. Www.kloc-0/1665.com Secondly, the development direction of China's construction market is determined by market demand. At present, people put forward higher and higher requirements for building performance, among which energy saving and thermal insulation is a universal basic requirement. In order to meet the market demand, building energy conservation is also very necessary.

Second, the building roof energy saving and thermal insulation waterproof measures

In building construction, in order to realize energy saving, thermal insulation and waterproof of buildings, the common technical measures are to adopt new roof thermal insulation materials, and improve the thermal insulation and waterproof performance of buildings through design and construction, so as to achieve the effect of energy saving and seepage prevention. The most commonly used roof insulation materials mainly include expanded perlite, polystyrene foam, rigid foam polyurethane and so on.

Using new energy-saving thermal insulation materials for building roof construction can not only effectively improve the building envelope, but also effectively solve the problem of roof leakage, reduce the damage and erosion of rainwater leakage to the internal structure of the building, greatly prolong the service life of the building, reduce maintenance costs and improve the living comfort of residents. Therefore, it is the most effective, economical and convenient technical measure to adopt new high-performance energy-saving thermal insulation and waterproof materials as energy-saving thermal insulation and waterproof measures for building roofs.
