The oven door with glass is made from refractory materials by casting and forging. Products of Finnish, Slovenian and Russian production are in demand. With the right selection of steel and glass, self-assembly is possible.
The need for fireplace doors
Steel and cast iron oven door with glass is traditionally used for Russian fireboxes. It contributes to the aesthetic pleasure of observing the combustion process and allows you to know about the need for a log lining. Open oven operation does not comply with fire safety and economy standards.
Tightly closed shutters increase the efficiency of the use of fuel resources, eliminating the possibility of sparks entering the living space. Sealing properties are achieved using a heat-resistant cord. The seal is placed in the gap between the frame and the glass insert, preventing the possibility of damage during expansion.
Modifications of furnace doors
A properly selected firebox door for a furnace with glass appears on the domestic market in the form of heat-resistant glass-ceramic, framedmetal frame or frame. Decorative properties are given by mosaic and embossed overlays, forged and cast parts. Frames are painted in traditional shades or using patination technology. Glasses are tinted or stained-glass windows are created. Patterns, ornaments and textured design elements are applied on the transparent coating.
If you need a heat-resistant oven door with glass, you can make the right choice among popular modifications:
- even;
- semicircular, radius;
- prismatic;
- bay windows;
- quadrangular or arched models.
It is important to decide on the opening method:
- swing;
- folding;
- sliding;
- lifting products.
Cast-iron oven doors with glass are of enviable quality and versatility.
Attractive Moments
Innovative solutions for equipping frames with air-cooled glass doors are driving the increased demand for safety products. The handles are made from a material with a low level of thermal conductivity. Many models include the installation of a blower system.
New doors for stoves and fireplaces with glass allow you to reduce the distance of approach to a red-hot stove. The safe properties of the coatings contribute to the convenient placement of structures in a house with children. Doors with removable handles eliminate the possibility of touching the enticing flames.
About heat resistant glass
Glass technology includesseveral stages: heat treatment, application of chemical compositions and polishing. Blowing with a hot air stream 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: doors for sauna ovens with glass have increased aesthetic and heat-resistant characteristics (up to 900 gr.), along with a low expansion coefficient and form integrity. They attract attention with a high level of sound absorption and slow heating.
The transformation of tempered glass into transparent glass-ceramic was the first step towards the introduction of relief and crystal coatings, tinting. To muffle the bright glare of the flame, self-cleaning structures with a barely noticeable layer of metal oxide are successfully used. The coating allows you to increase the temperature of the inner wall of the glass, and the fallen soot is completely destroyed under the flames.
What to look out for
Regardless of whether the oven door with glass was created by hand or purchased from a company store, it is important to adhere to the allowable temperature range indicated in the data sheet to prevent damage to it. The service life is indicated in hours and is determined by the operating level of heating of the furnace. The thickness of the glass is determined by the size and power of the furnace (4-12 mm).
Self-control and adjustment of the heating of an open flame cancause some inconvenience. Choosing products with a maximum limiting temperature will easily solve this problem. The high popularity of heavy-duty structures is due to the multilayer structure. Single panes are well suited for smaller home installations.
Manufacture of fireplace doors
When choosing cast iron oven doors with glass, Finnish designs from well-known companies (SVT and PISLA or HTT) are something to look out for. They are marketed under the HTT Design brand. The high quality of foreign production ensures the choice of practical products with wide flanges.
Steel structures retain their original properties for a long time due to the application of heat-resistant paint. The disadvantages include the high cost and the inconsistency of the parameters for our brick. This complicates the work of stove-makers.
In Russia, furnace casting is regulated by the RST RSFR 678-82 from gray cast iron SCH 15 GOST 1412-79. Products are characterized by simple execution and low cost. Slovenian products ("Litkom") 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 the finished structure. In the process of erecting the furnace, 4 threaded spokes are used, which are provided for walling into the mortar horizontally between the bricks. The frame is fixed during the curing of the mortar.
If plannedinstallation in a finished fireplace, 4 drilled holes Ø 4 mm are required. The frame is fastened with screws Ø 5 mm. Between the door and the masonry there is a technological indent of 5 mm. It is filled with refractory wool. For maximum compliance with fire protection requirements, it is important to place a metal floor sheet (from 400 mm wide) in front of the fireplace.
Self-creation of the oven door
Step by step description of the process:
- A corner is cut according to the drawing and inserted into a given shape.
- The diagonal is checked, the frame is welded.
- Weld welds are being cleaned.
- The frame of the planned sash is placed on a metal plate to mark the internal contour of the installation.
- The sheet is overlapped, eliminating the penetration of smoke into the room.
- A grinder is used for cutting metal structures.
- The 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 detergents without chlorine and abrasives. Work is carried out in a timely manner and with the glass completely cooled down.
