What energy-saving materials are there?

If you want to build a wall with rammed earth or adobe, the biggest advantage is that there are many materials, free of charge, and you don't have to transport them to the construction site. The downside is that it is difficult for you to find craftsmen who understand this technology.

vacuum insulation panel

On a one-inch (2.54cm) panel, the thermal insulation effect of vacuum insulation panel (VIP) is seven times that of traditional materials. This is probably the ultimate heat shield technology. But at present, it is only used for commercial and industrial refrigeration and special containers.

Vacuum insulation panel looks like the spacecraft technology in the old NASA movies. It is a rectangular object with silver texture, which consists of a core material and a sealing layer. The manufacturer can adjust the size of the board at will.

low emissivity

The letter E in Low-E stands for emissivity. The colorless metal oxide coating on these glasses can keep indoor heat in winter, but it can keep heat out in summer.

Usually, this kind of paint is used for the exterior windshield of a room without double windows. This technology is divided into soft coating and hard coating. The soft coating is between two layers of glass, and the hard coating is outside.

Recycle wood/plastic composite board

Have you ever wondered where all the plastic bags have gone? If you recycle them, they may appear in your next rooftop building or local playground.

According to the National Association of Residential Builders, wood fibers and waste plastics are more durable and less toxic than traditional wood. This material is also harder than pure plastic board because the wood fiber is reinforced.

Although the composite board will not be moldy and rotten, it will be hard at low temperature and soft at high temperature. And it is obviously much more expensive than traditional plate products.

Structural insulation board

Think about Oreo cookies, and you can imagine what a structural insulation board (SIP) looks like. Structural insulation board is made of a layer of thermal insulation foam plastic, sandwiched between plywood, particleboard or cement board.
