When decorating a new house, many small details cannot be ignored. Decorators usually use styrofoam and cement as filling materials when caulking doors and windows. In fact, both materials have advantages and disadvantages, so many owners will be confused about how to choose them.
Is it cement or styrofoam to be used for caulking doors and windows? Today Xiaobian comes to talk with you~
cement
Advantages: it is a relatively traditional way of filling with cement, which is cheap and durable.
Disadvantages: it takes a long time to fill the joint with cement, with a large amount of cement, and small cracks are easy to appear. In addition, if the window frame is made of aluminum, when filling the joint with cement, pay attention to protective measures to avoid the corrosion of aluminum materials.
Note: when using cement paste, aluminum window frame shall be protected, otherwise it is easy to be corroded.
Styrofoam
Advantages: foam plastics belong to soft gelatin, which has good energy saving and environmental protection characteristics. Besides, the insulation effect of foam plastics is also good, and it can be closely combined with the gap of window frames. It is not necessary to worry about the possibility of seepage by cracks, and the construction of foamed plastics is convenient and time-saving.
Disadvantages: the cost is high, but for cement slurry, the labor cost can be reduced.
Cement or styrofoam for joint filling?
Although foaming agent is superior to cement paste in many places, different materials can be selected for construction according to different areas.
Generally speaking, there are many cement constructions in the south, cold winter in the north, good thermal insulation performance of foaming agent, and high cost performance of foaming agent in the north.
In addition, cement mortar is recommended for the wooden window frame, because there is no corrosion problem in the wood window frame at first, and as long as putty is applied in the later stage, the appearance will not be affected; other materials, especially aluminum window frame, have better effect when used together with styrofoam, and will not corrode the doors and windows.
Although the styrofoam is good, the small braid should also be reminded that the styrofoam is not filled with any gaps. Whether the door and window gaps can be filled with Styrofoam depends on the size of the gaps.
The details are as follows:
① When the gap is less than 5cm, it can be filled with Styrofoam first (for outdoor windows, it is recommended to waterproof the outermost layer to prevent the styrofoam from being wet in rainy days)
② When the gap is more than 5cm, it needs to be filled with brick or cement
If the gap between doors and windows is small, it is better to use styrofoam.
