Window Frame Materials
Aluminum Alloy: The price of common aluminum alloy window frames is moderate, generally around 200 to 500 yuan per square meter. Its advantages include being lightweight, having high strength, being corrosion-resistant, and being easy to process, making it suitable for large-scale production. However, the thermal insulation performance of common aluminum alloy is relatively poor, and it may not be suitable for some areas with high requirements for thermal insulation. You should think carefully when purchasing this material and make a choice based on the local climate.
Broken Bridge Aluminum: Broken bridge aluminum is made by conducting broken bridge thermal insulation treatment on the basis of aluminum alloy. An insulation strip is added in the middle, which can effectively block heat conduction and greatly improve the thermal insulation performance. The price usually ranges from 500 to 1500 yuan per square meter. Due to its good performance, it is widely used in medium and high-end buildings.
Plastic Steel: The price of plastic steel window frames is relatively affordable, approximately around 150 to 400 yuan per square meter. It has good thermal insulation performance and also a good sound insulation effect. Moreover, with its low price, it is suitable for consumers who are sensitive to price. However, the strength and durability of plastic steel are slightly inferior to those of aluminum alloy. After long-term use, problems such as deformation and fading may occur.
Solid Wood: Solid wood window frames have a good texture, are beautiful and elegant, and can add a unique charm to the building. But the price is relatively high, which can reach 1000 to 3000 yuan or even more per square meter. Solid wood window frames need regular maintenance, such as painting, to prevent the wood from getting damp, deforming, rotting, and being damaged by insects, so the maintenance cost is relatively high.
Glass Types
Ordinary Single-layer Glass: The price is relatively low, ranging from tens to over one hundred yuan per square meter. However, its thermal insulation and sound insulation effects are poor, and it can only meet the basic functions of lighting and wind prevention. It is generally less used for casement windows with high performance requirements.
Double-layer Insulating Glass: It consists of two layers of glass with an air layer in the middle, and it has good thermal insulation and sound insulation performance. It is a commonly used glass type for casement windows at present. The price is about 100 to 300 yuan per square meter. Factors such as the thickness of the air layer, the quality of the glass, and the sealing performance will all affect its performance and price.
Triple-layer Insulating Glass: It has one more layer of glass and an air layer compared to double-layer insulating glass, and its thermal insulation, sound insulation, and heat insulation effects are better. But the price is also higher, usually around 200 to 400 yuan per square meter. It is suitable for places with extremely high requirements for sound insulation and thermal insulation, such as near airports and in bustling commercial areas.
Laminated Glass: It has high safety. Even if the glass is broken, the fragments will be stuck together by the middle adhesive layer and will not scatter and hurt people. It is often used in places with high safety requirements, such as schools, kindergartens, and high-rise residential buildings. The price of laminated glass varies depending on factors such as the material of the adhesive film and the thickness of the glass, generally around 150 to 500 yuan per square meter.
Low-E Glass: It can effectively block ultraviolet and infrared rays, reduce the heat loss in the room, and has good energy-saving effects. The price is relatively high, being tens to over one hundred yuan more expensive per square meter than ordinary glass. With the continuous increase of people’s requirements for energy conservation, Low-E glass is being used more and more widely in casement windows.
Hardware Accessories
Handles: Handles are made of various materials, such as plastic and metal. Plastic handles are relatively cheap, costing from a few yuan to more than ten yuan each, but their texture and durability are relatively poor. Metal handles made of materials like stainless steel and copper have better quality and an exquisite appearance, with the price ranging from dozens to over one hundred yuan each. Some handles of high-end brands also have unique designs and functions, and the price will be even higher.
Hinges: The load-bearing capacity and quality of hinges directly affect the service performance and lifespan of casement windows. Common hinges are relatively low in price, costing from a few yuan to more than ten yuan each. However, hinges with strong load-bearing capacity and good quality, such as those made of stainless steel and with a buffer function, may cost around dozens of yuan each. For large or heavy-duty casement windows, hinges of better quality and higher price are needed to ensure the stable opening and closing of the windows.
Locks: The price of common locks is relatively low, ranging from more than ten yuan to dozens of yuan per set, but their anti-theft performance is relatively weak. High-end locks with anti-theft and anti-pry functions, such as smart locks or mechanical locks using advanced anti-theft technologies, are more expensive, and each set may cost several hundred yuan or even thousands of yuan.
Brand and Quality
Well-known Brands: Casement windows of well-known brands usually have better guarantees in terms of product quality, process level, and after-sales service, and the price will be correspondingly higher. These brands pay attention to product research and development and production management, use high-quality raw materials and advanced production processes, and the products have better precision and stability. For example, the price of casement windows of some first-tier domestic brands may be 20% to 50% higher than that of ordinary brands.
Quality Differences: Product quality is mainly reflected in aspects such as material selection, processing technology, and assembly precision. High-quality casement windows will use better-quality profiles, glass, and hardware accessories in terms of materials, strictly control the dimensional accuracy and surface quality during the processing process, and the assembly process is also more refined, thus ensuring that performance indicators such as the sealing, water tightness, and air tightness of the windows reach a high level. However, casement windows of poor quality may have various problems after being used for a period of time, such as air leakage, water leakage, and damage to the hardware.
