This guide offers a comprehensive strategy for selecting windows and doors for new homes, highlighting their importance for safety, soundproofing, thermal efficiency, and aesthetics. It details key considerations ranging from material choices and performance parameters to specific window/door types and crucial aspects of purchase and installation, aiming to help homeowners create a comfortable and secure living space.
Window and Door Materials
- Aluminum Alloy: High strength, corrosion resistance, and versatility in finishes; "broken bridge aluminum" (断桥铝) includes thermal breaks for superior insulation.
- Plastic Steel (PVC): Budget-friendly with good sound and thermal insulation; however, it has lower strength and may deform or fade over time.
- Wood: Offers natural warmth and aesthetics; requires regular maintenance due to susceptibility to moisture and pests; composite wood provides a more durable and cost-effective alternative.
Key Performance Parameters
- Sound Insulation: Measured in decibels (30 dB+ is generally sufficient); enhanced by double or triple-pane insulated glass (often with inert gas) and high-quality EPDM sealing strips.
- Thermal Insulation: Determined by a low U-value (K-value); improved by "broken bridge aluminum," multi-layer insulated glass, and Low-E coated glass to reflect heat.
- Waterproofing & Sealing: Features include hidden drainage holes to prevent water accumulation and multi-layer sealing structures to block rain and dust infiltration.
- Safety: Employs tempered glass (shatters into dull particles) and laminated glass (remains intact upon breakage); requires strong, rust-resistant branded hardware for locks and hinges.
Types of Windows and Doors
- Window Types: Casement windows offer excellent sealing and insulation (available in inward or outward opening); sliding windows are space-saving but less sealed; folding windows provide maximum ventilation but may have higher hardware wear.
- Door Selection: Entrance doors should be Grade A anti-theft with C-grade lock cores for enhanced security; interior doors (e.g., bedroom, kitchen/bathroom) prioritize sound insulation (solid core, sealing strips) and moisture resistance (aluminum/titanium-magnesium alloy with frosted glass).
Purchasing and Installation Guidelines
- Avoid Low-Price Traps: Be wary of excessively cheap products that may compromise material quality or hardware; always choose reputable brands and verify product quality reports.
- Clarify Contract Details: Ensure the contract explicitly states material, dimensions, opening method, and hardware brand; include construction timelines and after-sales service terms.
- Emphasize Installation Quality: Improper installation can lead to drafts and leaks; opt for official brand installation teams and thoroughly inspect sealing, operation, and conduct water tests post-installation.
