Panels for door production
Panels for door production. Door plates. Door fillings – types and recommendations
Paper honeycomb – the least resistant to damage structure. The honeycomb is a properly formed contribution made of ordinary cardboard, which is stabilized by the hexagonal structure. The doors made in this way are characterized by low weight, and their main advantage is low price. However, doors made with this method are not durable and very poorly soundproofed. Chipboard-perforated board – provides much better acoustic insulation. It is a solution that also uses more durable materials, but hence – is more expensive than paper honeycomb. Internal doors made of chipboard are heavier and therefore more resistant to deformation.
The above examples are commonly used now, but are slowly being forgotten. Such fillings do not provide adequate insulation, they get wet easily, are poorly soundproofed and are susceptible to deformation. Currently, the material that we recommend and which we use as a door filling is the XPS board, i.e. extruded polystyrene foam – a hard foam without CFCs, maintaining certain, has long-lasting properties. XPS foam is characterized by a very low thermal conductivity and does not deteriorate, because this product is resistant to moisture and cyclic freezing and thawing. We recommend panels for the production of doors: Classic-Therm® with the filling of the aforementioned XPS, but the offer also includes fillings made of PUR polyurethane panels. Closed-cell PUR foam is light, provides excellent thermal insulation, and is also very resistant to water, therefore it is very often used, among others, in for anti-moisture protection.
Facings – types
HPL – HPL claddings are characterized by high bond strength between the layers. The structure does not crumble and does not separate due to impacts or vibrations, even where there are mechanical connections. The boards are mechanically and chemically resistant. HPL laminate has a smooth or structured surface that is easy to clean. Temperature resistance ranges from -60 ° C to + 80 ° C.

Aluminum – is one of the most durable variants when choosing door fillings. The advantages of aluminum are very good thermal insulation, attractive appearance, easy production, good corrosion resistance, low density, high strength to weight ratio and high resistance to cracking. Aluminum doors look like new even after many years of use.

PVC – here we will divide the category into hard PVC and foamed PVC. Hard PCV sheets are produced by extrusion in the form of flat sheets with a hard glossy surface. They are very easy to process and can be easily processed with commonly available tools. Foamed PVC, on the other hand, made of foamed PCW, are stiff, usually white, produced by the free foaming technique by extrusion. They have a regular internal structure with closed cells with a smooth external surface.

Plywood – is a composite material made by gluing thin layers of wood together at right angles. Crossing the fibers ensures uniform mechanical properties along and across the sheet. The properties of plywood are bending, tensile, compressive and shear strength than other wood-based products, such as MDF boards or OSB boards.

It is worth remembering that it is possible to use various types of inserts for panels, such as “ALU” or “dB”, which affects their anti-burglary or sound-absorbing properties. As a manufacturer with many years of experience in the sandwich panel industry, we offer Classic-Therm® panels for door panels with HPL cladding, aluminum panels, PVC door panels or plywood door panels. In the fenestration joinery industry, we offer several functional solutions, varied in terms of the structure of the board, the type of filling and the expected function.
