How to choose indoor wooden doors?

Product classification
Log door: Made of selected natural wood, without veneer finish treatment, to maximize the preservation of natural material color and texture. The materials selected include hemlock, walnut, etc., with beautiful and luxurious shapes, but expensive and high requirements for process treatment.
Solid wood composite door: Common ones are veneer solid wood composite door and veneer solid wood composite door. The veneer solid wood composite door generally uses finger-jointed fir as the inner core, with good surface texture, good sound insulation effect, environmental protection and not easy to deform. The inner core of the veneer solid wood composite door has a keel structure or a finger-jointed solid core, and the two sides are pressed with density board and then bark or paper skin, with good flatness, but there are certain defects in environmental protection and moisture resistance.
Molded door: It is made of two pieces of high-density fiber molded door skins with shapes and simulated wood grains by mechanical pressing, and the inner core is generally filled with wooden keel and honeycomb material. The price is economical and the texture is strong, but the sound insulation effect is poor and the style is limited.
Polymer door: It is made of two molded polymer panels pressed on the wooden skeleton, and filled with honeycomb materials and other materials through high temperature hot pressing. It is moisture-proof and waterproof, durable and moderately priced, but the sound insulation effect is poor, the shape and color selection are limited, and the surface scratches are not easy to repair.

Material selection
Wood types: Commonly used woods include softwoods such as fir and pine, and hardwoods such as walnut and oak. Cork is relatively low in price and soft in texture, while hardwood has a hard texture and beautiful texture, and is mostly used for high-end wooden doors.
Auxiliary materials: Including finger-jointed wood, medium-density fiberboard, etc. for door frames, and honeycomb paper for filling. Honeycomb paper filling can reduce the weight of the door, reduce costs, and at the same time ensure certain sound insulation and thermal insulation performance.
Manufacturing process
Log treatment: Dry the logs to reduce the moisture content and prevent the wooden door from deforming and cracking due to moisture or dryness during use.
Component processing: After cutting, planing, mortising, drilling, milling and other processes, the wood is processed into door supports, heads, door core boards and other components.
Assembly molding: Assemble the processed components according to the design requirements, fix them through mortise and tenon structures or connectors to form a door leaf frame, and then install the door core board, etc.
Surface treatment: You can choose painting, veneer and other processes. The painting process includes water-based paint, oil-based paint, etc. Water-based paint has good environmental protection performance, and oil-based paint has excellent paint film performance. According to the paint effect, it can be divided into open paint and closed paint. Open paint can see the wood texture and pores, and closed paint completely covers the wood surface.

Purchase points
Material: Choose the right material according to the budget and use requirements. Log doors are high-end but expensive, solid wood composite doors are cost-effective, and molded doors are economical and affordable.
Inspection process: Observe whether the surface of the door is flat and smooth, whether there are scratches, bubbles and other defects, whether the door gap is uniform, and whether it opens and closes smoothly.
Testing sound insulation: You can simply judge the sound insulation effect by listening to the sound after closing the door. Generally speaking, wooden doors with dense inner core filling and thicker door panels have better sound insulation effects.
