How to choose the most suitable home doors and windows? 2024 Guide to Choosing Windows and Doors to Avoid Pits
Introduction: Doors and windows are the “eyes” of a home, not only affecting lighting and ventilation, but also related to sound insulation, energy conservation, and safety. How should consumers choose from the dazzling array of door and window products on the market? This article will provide a detailed analysis from multiple dimensions such as material, performance, and price to help you make informed decisions.
Main content:
1. Large scale competition of mainstream door and window materials
aluminum alloy doors and windows
Advantages: high strength, corrosion resistance, long lifespan, diverse styles
Disadvantages: Fast thermal conductivity, poor insulation performance of ordinary aluminum alloy
Suitable scenarios: high-rise buildings, humid areas, modern style decoration
Price range: 300-800 yuan/square meter
Broken Bridge Aluminum Doors and Windows
Technical features: PA66 nylon insulation strip is used to disconnect the cold and hot bridges
Performance advantage: insulation performance improved by more than 30%, significant energy-saving effect
Key points for purchasing: Pay attention to the material of the insulation strip (avoid PVC impersonating nylon)
Price range: 600-1500 yuan/square meter
Plastic doors and windows
Advantages: Best insulation performance, affordable price, good sound insulation effect
Disadvantages: relatively low strength, prone to aging and discoloration
Upgraded product: Internal installation of steel lining to enhance strength
Price range: 200-500 yuan/square meter
Solid wood doors and windows
Advantages: High quality texture, environmentally friendly and natural, excellent sound insulation and thermal insulation
Disadvantages: expensive price, requiring regular maintenance, afraid of moisture
Maintenance requirements: repainting and maintenance are required every 2-3 years
Price range: 800-2000 yuan/square meter
2. Analysis of Key Performance Indicators
Sound insulation performance level
Ordinary doors and windows: soundproof 20-25 decibels (suitable for quiet communities)
Soundproof doors and windows: soundproof 30-35 decibels (suitable for general streets)
High sound insulation doors and windows: sound insulation of over 40 decibels (suitable for street facing and elevated areas)
Thermal insulation performance parameters
K value (heat transfer coefficient): The lower the value, the better the insulation
Ordinary single-layer glass: K value of about 5.0-6.0
Hollow glass: K value about 2.8-3.2
Low-E insulated glass: K value can be as low as 1.5-2.0
Safety performance standards
Profile wall thickness: National standard requirement ≥ 1.4mm
Glass requirement: Safety glass must be used
Hardware load-bearing capacity: ensuring the ability to withstand extreme weather conditions
3. Comprehensive Guide to Glass Selection
Hollow glass configuration
5+12A+5: Basic configuration, economical and practical
5+20A+5: Mid end selection for better insulation
Three glass and two cavity: high-end configuration, excellent performance
Special functional glass
Low-E glass: energy-saving preferred, reflective infrared
Laminated glass: safe and explosion-proof, unbreakable when broken
Dimming glass: intelligent control of transparency
Self cleaning glass: reducing maintenance needs
The Importance of Hardware Accessories
Core hardware components
Handle: Ergonomic design, comfortable switch
Hinge: key to load-bearing capacity, determining service life
Lock: Multi point locking, secure guarantee
Sealing strip: affects air tightness and water tightness
Brand Recommendation
Imported brands: German Noto, Siglia, Gewu
Domestic brands: Jianlang, Guoqiang, Yang
Purchase suggestion: Require merchants to provide hardware brand certification
5. The installation quality determines the final effect
Professional installation process
Accurate measurement: dimensional error controlled within ± 2mm
Hole treatment: repair of waterproof layer to ensure flatness
Door and window fixation: Expansion screw spacing ≤ 600mm
Gap treatment: fully filled with foam adhesive
Sealing treatment: double-sided gluing inside and outside
Debugging check: flexible opening and tight sealing
Acceptance Criteria
Verticality deviation ≤ 2mm/meter
Horizontal deviation ≤ 3mm/meter
Switching force: Handle operating force ≤ 50N
Airtightness: No air leakage phenomenon
Water tightness: No leakage in spray test
6. Price Trap and Avoidance Guide
Common price traps
Low price temptation: using inferior materials or reducing configuration
Area calculation: non-standard windows are calculated based on the maximum size
Invisible charges: installation fees, transportation fees, and accessory fees are separately calculated
Cutting corners: reducing the quantity of hardware or lowering specifications
Suggestions for avoiding pitfalls
Request a detailed quotation, including all costs
Sign a formal contract to clarify the material brand specifications
Retain the samples and compare and accept them upon arrival
Installment payment, leave sufficient warranty deposit
Conclusion:
Choosing doors and windows requires comprehensive consideration of material, performance, price, and service. It is recommended that consumers clarify their own needs and budget before making a purchase, and choose reputable brands and installation teams. Remember: the best doors and windows are not the most expensive, but the ones that are most suitable for you.
