Materials For Interior Doors Manufacturing – New Jersey Door Supplier

For the manufacture of interior doors, MDF boards, glued laminated timber, LVL timber, and honeycomb filling are used as the starting material.

MDF – Medium Density Fiberboard.

MDF board

This qualitatively new material is produced from dry wood fibers pressed with natural binder lignin. The result is a slab with a 1600 lb/10 sq. ft density.

Distinctive properties of this material are high rates of moisture resistance and fire resistance. It can be perfectly processed – it is sawn, painted. Made from environmentally friendly materials, the MDF board inherited these qualities – it is environmentally friendly, does not rot, and does not succumb to the harmful effects of fungi and microbes, which is superior to natural wood.

Plates are tested in special laboratories. They are tested for tension, bending, moisture resistance, roughness, and density. Thanks to its excellent performance, the MDF board has become one of the furniture and door production leaders.

Glued laminated timber

This high-tech material retains all the favorable properties of natural wood and eliminates its shortcomings. This product is stable. It does not require additional processing. It can be used immediately in production. Glued laminated timber is made from coniferous wood.

First, the boards are well dried in drying chambers until the required moisture level is reached (8% -12%), sorted, and defective areas are removed step by step. Next, the blanks are trimmed and dissolved into lamellas strictly according to the dimensions of the future timber. The slats are spliced “on a spike” and calibrated. After that, they are glued into a bar under pressure. At the end of the production stage, the timber is trimmed, planned, and polished.

The glued beam obtained in this way is very durable, does not deform, retains its geometric dimensions, and is not affected by moisture and temperature changes.

LVL timber(Laminated Veneer Lumber)

The production process of LVL timber is based on plywood production with technological changes.

This is a very durable structural material made from 9 or more layers of 3mm thick veneer glued together in the longitudinal direction of the fibers. As source material for the production of LVL timber, softwood veneer of the first cuts of the butt is used. After hydro-heat treatment and sawing, coniferous whips are peeled. The gloss dried in the convection chamber is sent for gluing, while humidity control is repeatedly performed.

This technology makes it possible to obtain a defect-free material with a solid layered structure. In terms of its strength and moisture resistance, it surpasses glued laminated timber, traditional timber, and other lumber. Today it is the best wood material in terms of manufacturability and mechanical performance, the bearing capacity of which is akin to metal structures.

Honeycomb filling for interior doors

This is a high-tech material for forming the door frame. Outwardly, it looks like a honeycomb, hence the name. Its primary purpose is to fill the free space between the skins of the solid pine frame, due to which the rigidity of the structure increases many times over.

Honeycombs are made of pressed cardboard or hardboard installed on an end. Such doors are much inferior in strength to massive ones, so they are recommended to be used only as interior doors in apartments or offices. Cloths are much lighter than massive ones and can withstand loads up to 80 kg.

Cellular technology was previously used in space exploration and is now being adopted by manufacturers of furniture and door products. Honeycomb core mainly consists of voids. Only 10% of the space is occupied by cardboard made from waste paper. Therefore, this is an energy-saving technology – expensive materials are replaced, and energy costs are reduced. Today it is a promising material for creating light and durable products for various purposes.
