When we carry out indoor wall insulation, it is very important to choose the right insulation material. Glass wool board is a high-quality thermal insulation material, and it is usually chosen as an indoor wall insulation material. Glass wool board with aluminum foil and without aluminum foil, do the internal wall insulation selection of glass wool board aluminum foil is a problem worth discussing.

Glass wool board itself has good thermal insulation, sound absorption and fire performance. The glass wool board with aluminum foil can prevent water from entering its interior and play a role in moisture resistance. At the same time, the aluminum foil can also enhance the fire resistance of the glass wool board. In addition, the aluminum foil layer can reflect part of the thermal radiation, further improving the insulation effect. In contrast, after the glass wool board increases the aluminum foil veneer, the cost will also increase.

So why do some people consider adding aluminum foil to a glass wool board? Nothing more than a few reasons: increase the fire performance, increase the thermal insulation performance, increase the waterproof performance.

However, in indoor wall insulation, it is usually not necessary to deliberately add aluminum foil to the glass wool board. This is because the main purpose of indoor wall insulation is to maintain a comfortable indoor temperature and reduce energy consumption. Glass wool itself has good thermal insulation performance, which can effectively reduce heat conduction and provide good thermal insulation effect.

In addition, adding aluminum foil to the glass wool board will also increase the complexity and cost of construction. In the normal indoor wall insulation, the glass wool board that meets the requirements of the code is generally selected, and the construction can achieve the expected insulation effect according to the correct installation method.

If the project has high fire performance requirements, the environment is relatively humid, and the funds are sufficient, aluminum foil glass wool board can also be used as the interior wall insulation material.

Therefore, under normal circumstances, when doing internal wall insulation, the glass wool board does not need to add an additional aluminum foil layer. Unless there are design requirements or special environment, it is necessary to increase the aluminum foil veneer. It is still necessary to make trade-offs and decisions according to the use environment and requirements.
