Finnish entrance doors: design features

Finnish doors are widely known in the European door construction market. The popularity of such models is due to their excellent performance, long service life and chic appearance.

Finnish doors are recognizable and in demand due to the following advantages:

• Reliability and durability of products. It is due to the use of high quality materials and design features. The frame of the door leaves consists of a multi-layer beam and aluminum sheet, which makes it quite rigid and not subject to deformation. The weight of the door structure is only 25-30 kg, which significantly reduces the load on the frame, hinges, load-bearing walls, and significantly extends the service life;

• Excellent sound and heat insulation properties are a distinctive feature of the construction of Finnish doors. They are due to the presence of several layers of CFC-free polystyrene foam, as well as the use of sealing circuits, which are highly resistant to temperature extremes and high humidity. The rubber bands of the seal do not dry out and do not crack under the influence of an aggressive environment, which ensures the preservation of the insulating properties of the product throughout the entire service life;
• Absolute environmental safety and the hygiene of the products are achieved through the use of natural materials such as solid pine, walnut and oak. When painting surfaces, harmless compounds are used that are highly resistant to household chemicals and moisture. It is not recommended to use alkalis and abrasive cleaning agents in the care of the products. Chips and dents that appear are easily removed with alkyd enamel;

• High burglar-proof qualities doors are achieved through the use of anti-removable hinges and locks with a high security class;
• Fire resistance of models complies with the safety class EI60, which guarantees the preservation of the insulating properties of the product and the integrity of the door leaf in contact with an open fire for an hour;
• Huge assortment products with a wide variety of colors, designs and textures allows you to choose a model for any interior. In northern European layouts, there is no entrance hall, so the inner surface of the canvas should be in perfect harmony with the interior decoration, match the color of furniture, walls and interior doors. Along with painted aluminum surfaces, the design of the canvases is represented by bas-relief and milled overlays with a pattern of any complexity and depth.

The door leaf from Finland, unlike its iron counterparts, has a sandwich structure. It consists of an aluminum sheet coated with weather-resistant paint, a frame made of laminated plywood and an extruded filler with a density of 200 kg per cubic meter. Layers of multi-layer LVL beams are directed in different directions. This gives the frame additional strength and rigidity. The inner side of the leaf is made of MDF sheet, which can be veneered and milled.

The outer aluminum sheet has a corrosion-resistant coating, which makes it possible to use Finnish doors in cottages and country houses.The door sills are made of 115x42 mm hardwood, covered with an aluminum plate on top.

Products are equipped with two locks:

• "Multihela-4565" possesses high protective properties, excellent burglary resistance and regulation of locking density.
• The second lock - "Abloy LC-100" allows you to open the door with one hand.

As an additional protection against burglary, anti-removable crossbars are used, which reliably fix the door leaf in the frame, even in the case of sawed-off hinges. The anti-release pins, which are equipped with all entrance models, will not allow to bend the corner or to squeeze out the door.

In the production of Finnish doors, a thermal break technology is used, the principle of which is the use of several separate insulation layers. Due to this, several layers of air are formed with a gradual decrease in temperature in each.

The use of this technology also prevents heat loss over the entire area of ​​the web, and drafts and blowing around the perimeter are reliably prevented by sealing rubbers. The lower thermal break is provided by a wooden threshold - this is another difference between Finnish doors and all-metal structures.

For example, the doors "Arctic" are made taking into account all the necessary requirements applicable to the models of the northern version and are very strong, durable and durable structures. When operated in the south, such products will reliably protect the home from heat and make the room's microclimate more comfortable. Finnish entrance models are slightly thicker than standard designs due to the presence of an additional layer of insulation. This is another feature of their design.

All Finnish door models are available in multiples of 10 cm in width and one centimeter in height. Products 90x210 and 100x210 cm are typical. According to the number of door leaves, there are two-leaf, single-leaf and one-and-a-half doors. The latter are produced in a width of 120 cm, of which the working sash is 90 cm. Such products are often decorated with forging and are installed as access doors.

Double doors are ideal for wide, custom openings and are often used in public spaces such as concert halls, theaters, schools and libraries. Double doors are another type of Finnish door design. They are made using hardwood, can have a one-and-a-half or double-leaf design, and have doubled protective and thermal insulation qualities. The outside of many models is decorated with forged hinges and patterns, which makes these products not only durable and reliable, but also gives them a chic appearance.

In addition to wood, aluminum and glass, insulated entrance doors are made of metal-plastic. Despite the seeming lightness of the canvas and low weight, these graceful designs are endowed with high protective qualities. Models are produced in a large assortment and a wide price range. Reinforced-plastic products do not require special care and have a long service life. Full metal models such as the Fenestra are also in high demand and are used for installation in technical rooms and garages.

Wood models are widely used as interior structures in residential and public spaces.They are made of high quality wood with all the necessary certificates of conformity. Each canvas is stamped with a proprietary marking and stamp of the manufacturing plant. This guarantees high quality and protection against counterfeiting.

From above, the canvases are covered with a varnish composition that protects the surface from moisture, temperature jumps and ultraviolet radiation. The structures are lightweight, easy to install and are much cheaper than their Italian counterparts. Furniture for wooden doors is presented with carved ornate or classic strict hinges and handles. The design of the canvases is often laconic, and the colors are cold. White models are also produced, which can be installed both in apartments and in offices.

Wooden doors are also manufactured in a fireproof version. They are able to provide reliable protection from fire and smoke, outwardly no different from ordinary wooden structures. This allows you to choose a fire-resistant model in any interior of the room. According to the design of the leaf, the doors are deaf, glazed and paneled. Paneled models are the most expensive and are made of solid walnut and oak. The service life of such products can be up to 100 years.

Among the entrance doors, a fairly well-known brand is Fenestra, which is presented on the market with the following collections:

• Classic series - these are restrained models of the classic style, which will look harmonious not only in old houses, but are perfect for new buildings as well. Products with a thermal break are made according to the "warm door" technology and meet all the requirements for this category of goods;

• Modern series - frost-resistant doors of modern design, which are distinguished by their practicality and impeccable style. They look unusual and are able to add variety to the interior of new directions. In the manufacture of these models, a thermal break technique is used, which gives the products of this series high thermal insulation qualities and an increased level of safety;

• Unique series presented with charismatic and exclusive options, made in a wide range of colors and a wide variety of designs. The doors of this series will reliably protect the home from frost, indicate the delicate taste and prosperity of the owners, and also perfectly decorate the interior. The models have high heat-saving properties and are able to withstand external temperatures up to minus 60 degrees.

The Jeld-wen brand is the most popular among interior doors. The products of this company have international certificates confirming the environmental safety of raw materials, high quality and guaranteeing a long service life. Along with the traditional interior models, the production of exclusive design options has been launched, with a wide variety of colors and styles.

Finnish street and interior doors are in high demand on the domestic market for door designs. Considering that most of the country is located in a zone with a cold climate, these models are in great demand among the Russian consumer. High heat-insulating properties of products and aesthetic appearance are noted. Attention is drawn to a long service life and an increased level of protection. Among the shortcomings, consumers single out the high price for some models and the absence of spare fittings in the free sale, which entails the need for its order at the manufacturing plants.
