Cast iron door for oven with glass

The door for the furnace with glass is created from refractory materials by casting and forging. Products of Finnish, Slovenian and Russian production are in demand. With the correct selection of steel and glass, independent installation is possible.

Need for fireplace doors

The steel and cast iron door for the oven with glass is traditionally used for Russian furnaces. It promotes aesthetic pleasure from observing the combustion process and allows you to learn about the need for a log liner. Operation of the furnace in the open condition does not comply with the norms of fire safety and economy.

The tightly closed flaps increase the efficiency of the use of fuel resources, excluding the possibility of penetration of sparks into the living space. Sealing properties are achieved using a heat-resistant cord. The sealant is placed in the gap between the frame and the glass insert, preventing damage during expansion.

Modifications of heating doors

Correctly selected furnace door for a furnace with glass appears on the domestic market in the form of heat-resistant glass-ceramic, framed by a metal frame or frame. Decorative properties give mosaic and relief pads, forged and cast parts. Frames are painted in traditional shades or by patination technology. The glasses are tinted or stained. On a transparent coating, patterns, ornaments and textured design elements are applied.

If you need a heat-resistant door for a stove with glass, you can make the right choice among the popular modifications:

• Smooth;
• Semicircular, radius;
• Prismatic;
• Bay window;
• Quadrangular or arched models.

It is important to determine the way of opening:

• Swinging;
• Folding;
• Sliding;
• Hoisting products.

Cast iron doors for furnaces with glass are distinguished by enviable quality and universal execution.

Attractive moments

Innovative solutions for equipping the frames with glass doors with air cooling affect the increased demand for safe products. To create handles, a material with a low level of thermal conductivity is used. Many models involve the installation of a blowing system.

New doors for stoves and fireplaces with glass allow to reduce the distance of approaching the incandescent furnace. Safe properties of coatings facilitate the convenient placement of structures in the house with children. Valves with removable handles prevent the possibility of touching the tempting tongues of the flame.

About heat-resistant glasses

The technology of creating glasses includes several stages: heat treatment, application of chemical compositions and polishing. Blowing with a hot air flow is carried out at the last stage, excluding the formation of chips and cracks. The finished product is characterized by perfect smoothness and transparency.

The result pleases with unique properties: the doors for sauna ovens with glass have enhanced aesthetic and heat resistant characteristics (up to 900 grams) along with a low coefficient of expansion and form integrity. They attract attention with a high level of sound absorption and slow heating.

The transformation of tempered glass into transparent glass ceramics was the first step towards the introduction of relief and crystal coatings, toning. To muffle the bright flares of the flame successfully used self-cleaning structures, which have a barely noticeable layer of metallic oxide. The coating allows to increase the temperature of the inner wall of the glass, and the burnt soot is completely destroyed under the tongues of the flame.

What to look for

Regardless of whether a glass oven door was created with your own hands or purchased in a branded store, it is important to adhere to the permissible temperature range specified in the data sheet to prevent damage to it. The service life is indicated in hours and is determined by the heating level of the furnace. The thickness of the glass is determined by the size and power of the furnace (4-12 mm).

Self-monitoring and adjusting the heating of an open flame can cause a number of inconveniences. The choice of products with the maximum limit temperature will easily solve this problem. The high popularity of heavy-duty structures is due to the multilayer structure. Single-pane glasses are good for small home installations.

Manufacture of fireplaces

Choosing cast-iron doors for ovens with glass, the Finnish designs of well-known companies (SVT and PISLA or HTT) are something that should be noted. They go on sale under the brand HTT Design. High quality manufacturing of foreign products provides a choice of practical products with wide flanges.

Steel structures retain their original properties for a long time thanks to the application of heat-resistant paint. The disadvantages include high cost and inconsistency of the parameters under our brick. To the ovens this complicates the work.

In Russia, furnace molding is regulated by the PCT RSFR 678-82 from gray cast iron MF 15 GOST 1412-79. Products are characterized by simple execution and low cost. Slovenian products (Litcom) are characterized by a reliable and familiar design for domestic users.

Installation of finished doors

Fireplace doors are mounted when laying the product or in a finished construction. In the process of erecting a stove, 4 spokes with a thread are used, intended for walling into the mortar horizontally between the bricks. The frame is fixed during the solidification of the building mixture.

If you plan to install in a finished fireplace, you need 4 drilled holes Ø 4 mm. Fastening of the frame is provided with screws Ø 5 mm. Between the door and the laying there is a technological indentation of 5 mm. It is filled with refractory wool. For maximum compliance with fire protection requirements it is important to place a metal sheet (from 400 mm in width) in front of the fireplace.

Self-construction of the oven door

Step-by-step description of the process:

• The corner is cut according to the drawing and inserted into the specified shape.
• The diagonal is checked, the frame is welded.
• Wave seams are cleared.
• The frame of the planned leaf is placed on a metal plate for marking the internal contour of the installation.
• The sheet is overlapped, excluding the penetration of smoke into the room.
• For cutting metal structures, a Bulgarian is used.
• Curtains are welded to the frame, tested for fixation strength.

It remains to eliminate the influx of welding and weld the handle.

Operation of fireplace doors

To maintain the appearance of the structure, it is important to periodically remove soot from the internal coating. This will be the usual wet rags and cleaning agents without chlorine and abrasives. Works are conducted in time and with complete cooling of the windows.
