1. Aluminum Windows
Overview
Aluminum has long been the material of choice for commercial buildings, and modern thermal break technology has made it equally compelling for residential use. Today's engineered aluminum windows — like those from EEHE — combine strength and slim aesthetics with insulation performance that rivals any other material.
Key Features (Based on EEHE Specifications)
Modern high-end aluminum windows incorporate thermal break technology — a PA66-GF25 nylon and glass fiber reinforced barrier inserted between the interior and exterior aluminum profiles. This "breaks" the heat conduction path that traditional aluminum windows were known for.
Thermal Break Architecture
PA66-GF25 Thermal Barrier: 66% nylon + 25% glass fiber reinforcement for toughness and strength, with high temperature resistance and anti-aging properties
Double Thermal Break Design (premium series): Two independent Technoform thermal barrier strips creating a five-layer structure — Outdoor aluminum → Barrier 1 → Insulation cavity → Barrier 2 → Indoor aluminum. Some series also feature polyurethane foam filling in the insulation cavity.
Multi-Chamber Design: 5 chambers with 4 ribs, each forming an independent air barrier that significantly reduces heat transfer and sound propagation
Same Isotherm Line Design: Optimized thermal insulation across the entire profile
Glass Configuration
Standard double glazing: 5mm + 20Ar + 5mm tempered glass with argon gas filling
Premium configurations: 5mm + 24Ar + 5mm or 5mm + 27Ar + 5mm
Optional LOW-E (Low-Emissivity) coating for superior thermal performance — blocking outdoor heat in summer and retaining indoor warmth in winter
Sealing System
Triple or more sealing layers
EPDM (Ethylene Propylene Diene Monomer) composite sealing strips
Seamless microwave vulcanization welding technology
EPDM lifespan: 30+ years without deformation or aging (vs. ordinary PVC sealing strips that degrade within 3 years)
Frame Construction
1.8mm national-standard primary aluminum (profile thickness ranges 1.6mm-2.2mm)
4th-generation pin injection glue process across the entire frame
Frame interior visible face as narrow as 22mm-30mm for a sleek, modern look
✅ Pros
| Advantage | Detail |
| Exceptional Strength | Aluminum's inherent strength allows for slimmer frames and larger glass panes, maximizing natural light and views. 1.8mm frame wall thickness provides rock-solid structural integrity. |
| Superior Thermal Performance | With thermal break technology, heat transfer is dramatically reduced. EEHE's thermal insulation reaches national standard Level 5. Combined with LOW-E glass, aluminum windows block outdoor heat in summer and retain indoor warmth in winter. |
| Wind Resistance | Engineered for high wind pressure resistance — EEHE's aluminum systems achieve national standard Level 9 (the highest grade), tested to withstand typhoon forces. |
| Sound Insulation | Multi-chamber cavity design + multi-layer sealing + laminated insulating glass forms a solid sound barrier. EEHE's sound insulation is tested at Class 5 level, jointly developed with Tsinghua University's Architectural Acoustics Laboratory. |
| Water Tightness | Multiple drainage systems, including concealed vertical equal-pressure drainage and stepped-track drainage, combined with one-piece welded sealing strips. EEHE achieves national standard Level 6 water tightness. |
| Low Maintenance | No painting, staining, or sealing required. Surface options include fluorocarbon coating with 10-year weather resistance. |
| 100% Recyclable | Aluminum can be recycled indefinitely without quality degradation. Over 75% of all aluminum ever produced is still in use today. |
| Long Lifespan | 30-50+ years with proper installation. EEHE offers a 10-year warranty on glass, aluminum, hardware, sealing strips, and thermal barrier strips, plus lifetime maintenance service. |
❌ Cons
| Disadvantage | Detail |
| Higher Initial Cost | Premium thermal break aluminum windows cost more than standard vinyl. The PA66 thermal barrier alone costs 5x more than ordinary PVC. Full injection glue process adds labor and material cost. |
| Thermal Conductivity (non-thermal break) | Basic non-thermal break aluminum is a good heat conductor — heat transfers directly through the metal profile. However, modern thermal break technology fully addresses this issue. |
Typical Cost Range
| Grade | Price Range (per m²) |
| Standard thermal break sliding windows | $200 – $350 |
| Mid-range casement windows | $250 – $400 |
| Premium thermal break windows | $350 – $500+ |
| EEHE reference: Oxford Time fixed | ~$255/m² |
| EEHE reference: Sunny Coast sliding | ~$276/m² |
Long-term savings note: While the initial investment is higher, annual air conditioning electricity savings can reach hundreds of RMB. Over 10+ years, total savings far exceed the initial price difference.
2. Vinyl (uPVC) Windows
Overview
Vinyl windows — made from unplasticized polyvinyl chloride (uPVC) — became popular for their low cost and reasonable basic insulation. They are common in North American residential construction, particularly in colder climates.
✅ Pros
| Advantage | Detail |
| Affordable | Lowest upfront cost among the three material types. |
| Good Basic Insulation | uPVC is naturally a poor heat conductor, providing reasonable thermal performance without requiring thermal break technology. |
| Low Maintenance | Does not need painting; occasional cleaning is sufficient. |
| No Corrosion | PVC is immune to moisture-related corrosion. |
❌ Cons
| Disadvantage | Detail |
| Lower Structural Strength | uPVC frames require larger, bulkier profiles to achieve adequate strength, reducing glass area and natural light. Steel reinforcement is often needed for larger openings. |
| Limited Color Options | White is standard; dark colors absorb heat and can cause warping. Color-coated options add cost. |
| Shorter Lifespan | Typical lifespan of 15-25 years. Ordinary PVC sealing strips degrade within 3 years, becoming hard and brittle. |
| Poor Fire Resistance | PVC melts and burns, releasing toxic fumes. |
| Not Eco-Friendly | PVC production involves harmful chemicals, and recycling is difficult and rarely done. |
| Thermal Expansion | uPVC expands and contracts noticeably with temperature changes, affecting seal integrity over time. |
| Less Aesthetic | Bulkier frames with limited customization options. |
Typical Cost Range
| Grade | Price Range (per m²) |
| Standard vinyl window | $100 – $200 |
| Premium reinforced vinyl | $200 – $300 |
| Custom color vinyl | $250 – $350 |
3. Wood Windows
Overview
Wood windows offer timeless beauty and natural insulation. They remain a top choice for historic homes, high-end renovations, and homeowners who prioritize aesthetics above all.
✅ Pros
| Advantage | Detail |

| Custom/clad wood | $500 – $800+ |
Head-to-Head Comparison by Priority
If You Prioritize Energy Efficiency
Modern thermal break aluminum windows offer the best insulation package when properly specified: multi-chamber design (5 chambers + 4 ribs) traps still air as insulation; PA66-GF25 thermal barrier (width up to 40mm) eliminates thermal bridging; argon gas-filled double/triple glazing reduces heat transfer; optional LOW-E coating reflects infrared heat; triple+ EPDM sealing system prevents air leakage. EEHE's thermal performance rating reaches national standard Level 5, with NFRC certification verifying energy efficiency.
If You Prioritize Budget
Vinyl windows cost 40-60% less than premium aluminum and 60-70% less than wood. However, their shorter lifespan (15-25 years vs 30-50+ years) means you may replace them sooner — potentially costing more in the long run.
If You Prioritize Aesthetics
Aluminum's high strength-to-weight ratio enables the slimmest frame profiles — EEHE's interior visible face is as narrow as 22mm-24mm, offering clean, modern sightlines. Wood wins for traditional and heritage aesthetics but requires ongoing maintenance.
If You Prioritize Low Maintenance
Aluminum windows require no painting, no staining, and no special treatments. A simple wash keeps them looking new. EEHE's fluorocarbon coating is tested for 10+ years of weather resistance.
Environmental Impact Comparison
| Material | Recyclability | Production Impact | End of Life |
| Aluminum | 100% infinitely recyclable | Energy-intensive but >75% of all aluminum ever produced is still in use | High scrap value; recycling uses 95% less energy |
| Vinyl (uPVC) | Limited; difficult to recycle | Produces dioxins and other pollutants | Most ends up in landfill; takes centuries to degrade |
| Wood | Biodegradable | Low embodied energy if sustainably sourced | Can be burned for energy or mulched |
