Not all those doors that look the same outside have the same internal content. The door leaf, the external design of which for many remains the only criterion for the choice, in fact should be selected according to its internal structure. There are several options here – it can be doors from an array, doors with cellular filling or doors with a monolithic filling.
The highest quality option is the door from the array. Such doors are completely made of a canvas of any tree breed. Options are cheaper made of pine, options are more expensive from other breeds, such as oak. There are exclusive options for an array, but in general, what the buyer needs to know about the doors from the array – inside they have a tree. More precisely, it will even say that the door from the array is a large wooden canvas without impurities of any other filling.
There are inexpensive doors, inside of which cellular filling. Such doors have a wooden frame, most often a cheap pine tree, inside of which there is a pressed cardboard. Roughly speaking, the manufacturer makes a small narrow box in the shape of a door from thin plates, and a cardboard is pressed into this box on the gap. The design itself allows such doors to be sold at a bargain price, although it will depend on the external design and wood of wood.
When it comes to continuous filling of the shield, it is most often implied that between two wooden tiles is the MDF plate as a filler. It can also be chipboard or fiberboard. The description is similar to how doors with a cellular filling are made, except that a monolithic filler is inside, and not a cellular. This allows the door to have a more worthwhile sound insulation and, in general, meet with great quality criteria than hollow doors.
Some doors are filled with a brown aggregate, that is, inside the bars of coniferous woods. Two options for filling two – either a continuous layer of bars, or with voids. The bars make the door more durable, but the option of such a door will be more expensive.
The Portal Project Rodge wants to study the internal content of the wooden product well before buying it.
