Can the glass configuration of the 80 Series window really be adjusted?
It can be adjusted. The glass configuration of the 80 Series window is not locked; the standard configuration 5+22A+5 is only a reference starting point. During actual procurement, the glass thickness, air gap width, or glass type (such as tempered, Low-E, laminated, etc.) can be adjusted according to project requirements. However, adjustments have prerequisites. First, let's break down the meaning of the standard configuration, and then discuss the feasibility of adjustments.
Meaning of the standard configuration 5+22A+5
This notation is a common abbreviation for glass specifications in the door and window industry:
- 5: Thickness of the glass substrate, in millimeters.The two "5"s indicate that both the inner and outer layers are 5mm glass.
- 22A: Width of the air gap, 22mm. A represents the air layer.
- 5+22A+5: Overall, it is a double-glazed unit consisting of "5mm glass + 22mm air gap + 5mm glass".
This configuration is a balanced solution for the 80 Series window: the 5mm glass meets standard wind pressure resistance and sound insulation requirements, while the 22mm air gap strikes a balance between thermal insulation and cost. If your project has higher requirements for energy efficiency or sound insulation, this configuration may not be sufficient.If the budget is tight, you can also consider thinner glass or a smaller air gap.
Feasibility of Adjusting Glass Configuration
Adjustments are possible, but three key conditions need to be confirmed:
- Profile Groove Compatibility: The profile design of the 80 series window has a fixed groove depth.If switching to thicker glass (e.g., 6mm or 8mm) or a wider air gap (e.g., 27A), it must be confirmed whether the glass bead and sealing strip can match.It is recommended to provide the desired total glass thickness (e.g., 6+20A+6=32mm) to the hyperstron team, and let them confirm whether the profile groove can accommodate it.
- Load-bearing and hardware matching: The heavier the glass, the higher the load-bearing requirements for hardware such as hinges and handles.If switching from 5mm to 6mm or 8mm, the glass weight increases by 20%-60%. It is necessary to confirm whether the current 80 Series window hardware supports it; otherwise, long-term use may cause sagging or difficulty in opening and closing.
- Glass type and production cycle: The standard configuration is ordinary float glass.If you need tempered, Low-E, laminated, or triple-glazed with two cavities, hyperstron can customize, but the production cycle and unit price will change.For tempered glass, it is necessary to confirm in advance whether the tempering furnace has production capacity scheduled; for Low-E glass, confirm whether the coating orientation affects the seal.
Who is suitable for adjustment?
- If the project has clear energy efficiency requirements (e.g., U-value ≤ 2.0 W/m²·K), upgrade to Low-E or triple glazing.
- If the project is located in a noise-sensitive area (e.g., near a street or airport), thicker glass or laminated layers are needed.
- If the budget is limited and you want to use 4mm glass or a 20A air gap to reduce costs.
Who is not suitable for adjustment?
- If the project has no special requirements for glass configuration, and the standard configuration already meets local building codes.
- If the project schedule is tight, custom glass may extend delivery time.
Next confirmation steps: Organize your project requirements (glass thickness, air gap width, whether tempered/Low-E), contact the hyperstron team directly, provide the profile cross-section drawing or product number of the 80 Series window, and ask them for compatibility confirmation and quotation.
Besides 5+22A+5, what other glass configurations are available?
The reference configuration for the 80 series single-opening aluminum alloy window is 5+22A+5 insulating glass, but this is just the starting point. In actual projects, the glass configuration can be adjusted according to requirements, mainly involving three variables:glass thickness、gas layer width、whether to add coating or lamination. Below, we will directly tell you which scenarios each adjustment is suitable for and which scenarios it is not suitable for.
Changing the glass thickness: from 5mm to 6mm or thicker
- 5mm → 6mm: If the project is located on a high floor (e.g., above 20 stories) or in a coastal area with high wind pressure, upgrading the single glass from 5mm to 6mm can significantly improve wind pressure resistance.The trade-off is an approximately 20% increase in overall window weight, placing higher demands on hinge and frame load-bearing capacity.The 80 Series profile has a wall thickness of 1.4mm and can typically support 6mm glass, but we recommend confirming the load calculation for specific dimensions with our team.
- 6mm and above (e.g., 8mm, 10mm): Generally used for oversized windows (e.g., single sash exceeding 2㎡) or scenarios requiring explosion-proof or anti-theft features.Note: Excessively thick glass significantly increases cost and installation difficulty, and the 80 Series profile groove may not be compatible, so it is necessary to confirm in advance whether the profile bead is compatible.
Suitable for: High-rise residential buildings, coastal projects, large-size windows. Not suitable for: Ordinary low-rise residential buildings (increased cost but limited benefits).
Adjusting the gas layer width: Options beyond 22A
The gas layer width (A stands for Air, i.e., air layer) directly affects thermal insulation and sound insulation performance:
| gas layer width | Changes in thermal insulation performance | Changes in sound insulation performance | Applicable scenarios |
| 9A or 12A | Worse than 22A, U-value increases by about 0.3-0.5 W/m²K | Mid-low frequency sound insulation decreases | Tight budget, mild climate regions |
| 22A (reference configuration) | Baseline | Baseline | Most residential and commercial projects |
| 27A or larger | Slightly better thermal insulation (U-value reduced by about 0.1-0.2) | Sound insulation improvement is not significant, but low frequencies can be optimized | Energy-efficient buildings with higher thermal insulation requirements |
Key trade-off: 22A is already the cost-effective balance point. Widening to over 27A yields diminishing returns in thermal insulation and requires thicker frame grooves (80 Series typically supports up to 27A; larger sizes need confirmation). If the main goal is sound insulation, it is recommended to prioritize laminated glass rather than simply widening the gas layer.
What scenarios are Low-E glass suitable for?
Low-E (low-emissivity) glass can reflect infrared rays, significantly reducing the heat transfer coefficient. Suitable for:
- Cold regions: Reduces indoor heat loss in winter, U-value can be reduced by 0.3-0.5.
- Hot regions: Blocks outdoor heat from entering in summer, combined with shading coefficient selection (high-transmittance type or shading type).
- Energy-saving certification projects: Such as green building, LEED certification.
Not suitable for: If the project has no energy-saving requirements and the local climate is mild (such as Kunming or Dali), Low-E glass is not cost-effective—it is usually 15-30 yuan/㎡ more expensive than ordinary clear glass, but the energy-saving benefits may take several years to recoup.
Laminated Glass: Priority Choice for Sound Insulation and Safety
If the project is adjacent to a main road, airport, or railway,5+0.76PVB+5laminated insulating glass (i.e., two panes of glass with a layer of PVB film sandwiched in between) is more effective than simply thickening the glass or widening the gas layer. It can significantly reduce low-to-medium frequency noise (such as tire noise and aircraft roar). At the same time, laminated glass shatters into fragments that adhere to the film, making it suitable for balcony windows or skylights with anti-fall requirements.
NoteLaminated glass is about 10-15% heavier than ordinary insulating glass, and the PVB film will slightly reduce light transmittance (about 3-5%). Projects with extremely high daylighting requirements need to weigh this.
Next confirmation steps
The above configuration adjustments are all based on the universal adaptability of the 80 Series profiles. However, depending on your project dimensions, opening type (inward/outward opening), and hardware load capacity, you need to provide the following information to our team to confirm the matching solution:
- Maximum size and area of a single sash.
- Basic wind pressure and energy efficiency standards of the project location.
- Whether sound insulation rating (e.g., ≥35dB) is required.
Based on these conditions, we will provide glass configuration recommendations and profile bead adaptation solutions to avoid issues such as glass not fitting or hardware overload.
Which projects are suitable for different glass configurations?
The reference glass configuration for the 80 Series single-opening aluminum alloy window is 5+22A+5 (5mm glass + 22mm air layer + 5mm glass). However, in actual projects, the glass configuration can be adjusted based on the project type and requirements. Below are the recommended and not recommended boundaries for different scenarios:
Residential Projects: Balancing Performance and Cost
- Suitable for: Ordinary residential buildings (self-built houses, commercial housing), especially when extreme requirements for heat insulation and sound insulation are not needed.The 5+22A+5 configuration already provides basic thermal insulation (the 22mm air layer effectively reduces the heat transfer coefficient) and sound insulation (the hollow structure reduces noise transmission), and the cost is controllable.If the budget is limited, consider 5+12A+5 (12mm air layer), sacrificing some thermal insulation performance but more economical.
- Not suitable for: If the project is located in a severe cold region (e.g., winter temperatures consistently below -20°C), the 5+22A+5 may not be sufficient and should be upgraded to Low-E coated glass or triple glazing (e.g., 5+9A+5+9A+5) to further reduce heat loss.In this case, the 80 Series window frame itself is compatible, but you need to confirm with the team whether the profile groove supports thicker glass.
Public Buildings: Prioritizing Energy Efficiency and Safety
- Suitable for: Projects such as schools, hospitals, and office buildings that have clear requirements for energy-saving design.The 5+22A+5 configuration can meet most energy-saving standards (e.g., heat transfer coefficient K value around 2.5-3.0 W/m²·K, depending on glass brand and filling gas).If higher safety levels are required (e.g., fall prevention, impact resistance), it can be changed to tempered insulating glass (e.g., 5mm tempered +22A+5mm tempered), increasing cost by about 15-20%, but significantly improving impact resistance.
- Not suitable for: If the project is located in a typhoon-prone area (e.g., coastal cities), the 5+22A+5 ordinary float glass may have insufficient wind pressure resistance.In this case, tempered glass or laminated insulating glass (e.g., 5+0.76PVB+5+22A+5) should be selected, along with reinforced profiles (e.g., wall thickness above 1.8mm).The 80 Series window frame can support this, but it is necessary to confirm with the team whether the profile cross-section meets wind pressure calculation requirements.
High-rise residential buildings: Do they require special glass configurations?
- Suitable for: High-rise residential buildings (above 10 floors) generally have higher requirements for glass wind pressure resistance and safety.The 5+22A+5 configuration is feasible in standard wind pressure zones (e.g., basic wind pressure ≤0.5kN/m²), but it is recommended to upgrade to tempered glass (at least the outer layer tempered) to prevent glass self-explosion or falling risks.If the project is located in a strong wind zone (e.g., coastal high-rise buildings), laminated insulating glass (e.g., 5+1.14PVB+5+22A+5) should be used, and the window frame must be securely connected to the wall.
- Not suitable forIf high-rise residential buildings require extremely low noise (e.g., adjacent to main roads), the sound insulation performance of 5+22A+5 (approximately 30-35dB) may be insufficient. In such cases, PVB laminated insulating glass (e.g., 5+0.76PVB+5+12A+5) should be used, which can improve sound insulation to 35-40dB.At this point, the 80 Series window frame can be adapted, but it is necessary to confirm whether the sealing strips and hardware are compatible.
Key Trade-offs and Next Steps for Confirmation
- Who is SuitableProjects with limited budgets and moderate performance requirements (e.g., ordinary residential buildings, standard public buildings) will find 5+22A+5 a cost-effective choice.
- Who is Not Suitable: For projects in extreme cold, typhoon-prone, high-noise, or high-rise strong wind areas, upgrade the glass configuration (Low-E, tempered, laminated) or consider a higher series (such as the 90 Series).
- Next Step Confirmation: Provide the current website team with the project's climate zone (e.g., severe cold, typhoon level), floor height, and energy efficiency standards (e.g., local K-value requirements). The team can then match the specific glass solution and profile wall thickness accordingly.
What key points should be noted when adjusting the glass configuration?
The reference glass configuration for the 80 Series window is 5+22A+5 (5mm glass + 22mm air layer + 5mm glass), but in actual projects, adjustments are often needed due to sound insulation, thermal insulation, or cost requirements. The following are three key points that must be confirmed before adjustment to help you avoid "cannot install after ordering" or "problems after installation".
Profile Groove and Load-Bearing Limits
The groove depth determines the maximum total glass thickness. The glass slot of the 80 Series profile is usually designed to accommodate an air layer of about 22mm. If you switch to thicker glass (such as 5+27A+5), the total thickness increases, and it may not fit into the slot or the bead may not snap on. **You must confirm with the Hyperstron team the maximum total glass thickness that this profile slot can accommodate.
**
Load-bearing capacity determines the upper limit of glass weight. Thicker glass is heavier. The 80 Series profile has a wall thickness of 1.4mm, and the hinges and frame have limited load-bearing capacity. For example, replacing 5mm single glass with 8mm increases the weight of a single pane by about 60%, which may cause the sash to sag or operate stiffly over long-term use.
You need to provide the glass specifications (thickness + dimensions) you plan to use, and have the Hyperstron team calculate whether the total weight under this configuration falls within the safe load-bearing range of the profile and hardware.
Confirm samples with the manufacturer
Do not place an order based solely on drawings. After adjusting the glass configuration, the following details must be verified through physical samples:
- Glazing bead matching: Different glass thicknesses require corresponding glazing bead specifications. If the bead is too narrow, it won't hold tightly; if too wide, it affects aesthetics.
- Sealing effect: Changes in the thickness of the insulating layer affect the compression of the sealing strip. If too loose, it leaks air; if too tight, the window cannot close.
- Hardware compatibility: After the glass becomes heavier, the original hinges and handles may need to be upgraded to heavy-duty versions.
Correct procedureFirst, provide your target glass configuration (e.g., "5+12A+5+12A+5" triple glazing) to the hyperstron team. After they confirm that the profile groove and load-bearing capacity are feasible, request a physical sample (usually 1㎡ is sufficient). Upon receipt, check the fit of the pressure strips, the feel of the switch operation, and whether the sealing strips are evenly compressed.
Pre-batch purchase confirmation checklist
Before placing a batch order, be sure to complete the following three steps to avoid rework on a large scale:
- Confirm the glass supplierWill you purchase the glass yourself or will hyperstron provide it?If purchasing glass yourself, you need to send a glass sample to hyperstron in advance for trial installation of pressure strips and sealing strips.
- Confirm tolerance range: The thickness tolerance of the hollow layer from different glass factories may reach ±1mm, so it is necessary to confirm whether the hyperstron profiles can accommodate this tolerance.
- Small batch trial installation: First order 5-10 sets, observe for one week after installation (especially check whether the switch is smooth and whether there is any abnormal noise), then proceed to large batch.
Common issues
Q1: I want to replace 5+22A+5 with 5+12A+5+12A+5 triple glazing with two cavities. Can the 80 series accommodate it? A: Not necessarily. The total thickness of triple glazing with two cavities is usually 5+12+5+12+5=39mm, plus the adhesive layer about 41mm, while the groove depth of the 80 Series is typically 30-35mm.
You need to confirm the groove dimensions with the hyperstron team. If insufficient, you may need to use thinner glass (e.g., 4mm) or switch to another series.
Q2: Will the window be more prone to water leakage after the glass is thickened? A: No, if the bead and sealing strip are properly matched. However, the increased weight of the glass may cause slight deformation of the sash, damaging the original drainage slope.
It is recommended to simulate a water spray test (using a shower head to spray the window frame joints) during the sample stage to check for any leakage.
Q3: Can I buy the glass locally and only have Hyperstron provide the window frames? A: Yes, but you must send a glass sample to Hyperstron in advance for trial assembly. Different glass factories have different chamfering and thickness tolerances; direct mass production may result in the bead not fitting.
Q4: What is the maximum glass thickness that the 80 Series can accommodate? A: There is no one-size-fits-all answer; it depends on the profile groove depth and load-bearing design. The common upper limit is a total thickness of 32mm (e.g., 5+22A+5), but you need to provide your glass specifications to the hyperstron team for confirmation.
Q5: Will adjusting the glass configuration affect the thermal insulation performance of the window? A: Yes. Reducing the thickness of the air layer from 22mm to 12mm will decrease thermal insulation performance by about 15-20% (U-value increases); switching to triple glazing with two cavities will improve it by about 10-15%.
It is recommended to ask hyperstron to provide an estimated heat transfer coefficient (U-value) after adjustment, and then compare it with your energy efficiency requirements.
