What is the thickness of a standard interior door

Door thickness, sleeve board 3cm

The year before last, the state promulgated the "Interior Door Standard" with reference to the "Residential Design Code", which clearly stipulates that the thickness of the door is greater than or equal to the thickness of the door sleeve and the thickness of the door sleeve is greater than or equal to 3cm. Haomen wooden door is the first demonstration and leading enterprise of this standard in China.

However, there are still many manufacturers of doors that do not meet the standards in the regulations, which can save costs, and regular enterprises are larger than the thick door, and the thickness of the sleeve board should be greater than 3cm.

The standard width of the solid wood door of the bedroom door is 80 cm, and the installation of the solid wood door needs to pay attention to the door sleeve and the door hole after filling it with a wooden wedge, and then use wave nails to fix the door cover and the wooden board in the door opening, if you find that the gap is too large, you can fill it with styrofoam. After installing the door leaf on the door cover, adjust the flexibility of the door leaf to test the opening, and check whether the door crack meets the standard size.

The year before last, the state issued the "Interior Door Standard" in accordance with the "Residential Design Code", requiring the thickness of the door to be greater than or equal to 45mm and the thickness of the door sleeve to be greater than or equal to 30mm.

As long as it is a large manufacturer, a big brand, and a regular enterprise, it must produce doors with a thickness of more than 45mm, and the thickness of the sleeve board must be greater than 30mm. At present, some manufacturers have been delaying, or producing a part, or users do not understand to do non-standard, which will save a lot of costs, but sooner or later they must also produce 45mm thick, otherwise they will be disqualified from production!

Compared with the non-standard, the standard door with a thickness of 45mm greatly improves the thermal insulation and sound insulation effect between the interior and the outside world, and your sleep quality will be improved by 22% According to the "Residential Design Code", "the allowable noise in the bedroom and living room of the residence should be less than 50 decibels, and less than 40 decibels at night.
