Ministry of Construction will promote new polyurethane building materials
Recently, the National Medium- and Long-Term Special Plan for Energy Conservation has stipulated that energy-saving standards should be strictly implemented for new buildings during the “Eleventh Five-Year Plan†period, and existing buildings should be gradually implemented with energy-saving renovation. To this end, the Ministry of Construction will comprehensively promote new building energy-saving technologies from this year, and promote polyurethane materials as a substitute for traditional building insulation materials.
When a junction box is used for every electrical connection in a building it is much easier to locate and repair any electrical problems that come up.
When some connections are made without junction boxes, such as inside wall cavities or in hidden ceiling or attic locations, the likelihood future problems increases.
Every electrical connection should be inside a protective box that is easy to find and access.
