The door for the furnace with glass is created from refractory materials by casting and forging. Finnish, Slovenian and Russian products are in demand. With the right selection of steel and glass, self-assembly is possible.
The need for fireplace doors
The steel and cast-iron door for the furnace with glass traditionally serves for Russian furnaces. It contributes to the aesthetic pleasure of observing the combustion process and allows you to learn about the need for lining of logs. Operation of the furnace in the open state does not comply with fire safety and economy standards.
Tightly closed flaps 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 sealant is placed in the gap between the frame and the glass insert, preventing the possibility of damage during expansion.
Modifications of the furnace doors
A correctly selected furnace door for a furnace with glass appears on the domestic market in the form of heat-resistant glass ceramics framed by a metal frame or frame. Mosaic and relief overlays, forged and cast details give decorative properties. Frames are painted in traditional shades or using patination technology. Glass tinted or stained glass. On a transparent coating, patterns, ornaments and textured design elements are applied.
If you need a heat-resistant door for an oven with glass, you can make the right choice among popular modifications:
- smooth;
- semicircular, radial;
- prismatic;
- bay windows;
- quadrangular or arched patterns.
It is important to determine the method of opening:
- swinging;
- folding;
- sliding;
- lifting products.
Cast iron doors for furnaces with glass are of enviable quality and universal design.
Attractive moments
Innovative solutions for equipping frames with air-cooled glass sashes affect the increased demand for safe products. To create pens, a material with a low level of thermal conductivity is used. Many models involve the installation of a blower system.
New doors for stoves and fireplaces with glass reduce the distance to the incandescent furnace. Safe coating properties contribute to the convenient placement of structures in a home with children. Sashes with removable handles exclude the possibility of touching the attractive tongues of the flame.
About heat resistant glasses
The technology for creating glass includes several stages: heat treatment, applying chemical compositions and polishing. Hot air blowing is carried out at the last stage, eliminating 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 bath stoves with glass have enhanced aesthetic and heat-resistant characteristics (up to 900 gr.) Along with a low coefficient of expansion and shape 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 on the path of introducing relief and crystal coatings, tinting. Self-cleaning structures with a barely noticeable layer of metal oxide are successfully used to muffle bright glare of the flame. The coating allows you to increase the temperature of the inner wall of the glass, and fallen soot is completely destroyed under the tongues of flame.
What to look for
Regardless of whether you made a door for an oven with glass with your own hands or purchased in a company store, to prevent its damage, it is important to adhere to the permissible temperature range indicated in the data sheet. The service life is indicated in hours and is determined by the operating heating level of the furnace. Glass thickness is determined by the size and power of the furnace (4-12 mm).
Self control and regulation of heating an open flame can cause a number of inconveniences. Choosing products with a maximum temperature limit indicator will easily solve this problem. The high popularity of heavy-duty structures is due to the multilayer structure. Single-pane glass is well suited for small home installations.
Fireplace Sash Production
Choosing cast-iron doors for ovens with glass, Finnish designs of well-known companies (SVT and PISLA or HTT) are what you should pay attention to. They go on sale under the brand name HTT Design. High quality manufacturing of foreign products provides a selection of practical products with wide flanges.
Steel structures retain their pristine properties for a long time thanks to the application of heat-resistant paint. The disadvantages include the high cost and inconsistency of the parameters for our brick. This complicates the work of stove-makers.
In Russia, furnace casting is regulated by PCT RSFR 678-82 from gray cast iron SCH 15 GOST 1412-79. Products differ in 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 a finished structure. During the construction of the furnace, 4 threaded needles are used, which are provided for wiring horizontally between the bricks in the mortar. The frame is fixed during the hardening of the building mixture.
If you plan to install in a finished fireplace, you will need 4 drilled holes Ø 4 mm. The frame is secured with Ø 5 mm screws. A technological gap of 5 mm remains between the door and the masonry. It is filled with refractory wool. For maximum compliance with fire safety requirements, it is important to place a metal sheet (from 400 mm wide) in front of the fireplace.
Do-it-yourself oven door
Step-by-step process description:
- The corner is cut out according to the drawing and inserted into a given shape.
- The diagonal is checked, the frame is welded.
- Weld flows are cleared.
- The frame of the planned sash 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.
- 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 inside. This will serve as a normal wet rags and detergents without chlorine and abrasives. Work is carried out in a timely manner and with complete cooling of the glass.
