How to choose aluminum wrapped wood
How to choose aluminum wrapped wood, aluminum, PVC Sunroom
The following is a detailed comparative analysis of three types of sunroom materials: aluminum Clad Wood, aluminum alloy (bridge cut aluminum), and PVC, combined with comprehensive evaluation of performance, cost, and applicable scenarios:
1、 Core performance comparison
Index: Aluminum clad wooden sunroom, aluminum alloy sunroom, PVC sunroom
Durability of over 30 years (outer aluminum+inner anti-corrosion wood) 20-30 years (broken bridge aluminum) 10-15 years (prone to aging)
Thermal conductivity of insulation wood 1.3 Broken bridge aluminum 2.0-3.0 (filled with insulation strips) 2.2 (multi cavity structure)
Anti wind pressure (composite structure) extremely strong (aviation aluminum load-bearing capacity of 1 ton+) generally (steel lining required)
Low maintenance cost (only requires regular maintenance of wood), almost maintenance free, high (requires replacement of aging rubber strips)
Environmentally friendly wood renewable+aluminum recyclable Aluminum recyclable Petroleum based materials difficult to degrade
2、 Suggested Applicable Scenarios
Aluminum clad wooden sunroom
Suitable for high-end scenes such as villas and courtyards, natural wood grain enhances the overall texture, and the double-layer structure has excellent sound insulation effect.
Recommend pairing with Low-E glass, which has a 40% improvement in winter insulation performance compared to ordinary bridge cut aluminum.
Aluminum alloy sunroom
High rise residential buildings or typhoon prone areas are preferred, with a 2.0mm thick aviation aluminum material that can withstand wind speeds up to level 12.
High cost-effectiveness, when budget is limited, ordinary aluminum alloy can be selected (note the insulation short board).
PVC sunroom
Only suitable for temporary construction or extremely low budget scenarios, long-term use can easily deform and turn yellow.
Caution should be exercised in cold northern regions as brittleness increases at low temperatures.
- Cost and Process Differences
Aluminum clad wood: The unit price is relatively high, and customized production is required (with a cycle of about 60 days).
Broken bridge aluminum: Medium unit price, standardized production (cycle 3-7 days).
PVC: The unit price is relatively low, but the high frequency of replacement leads to long-term cost overruns.
4、 Precautions
Priority should be given to selecting bridge cut aluminum and micro arc oxidation treatment (salt spray resistance for 5000 hours) in coastal areas.
PVC material is strictly prohibited from being used for load-bearing structures, and the aging of connecting components needs to be checked regularly.
Aluminum clad wood should be imported wood with a moisture content of ≤ 12% to avoid cracking in the north.
Selection of Wood for Aluminum Clad Wood Sunrooms
The selection of wood for aluminum clad wooden sunrooms should comprehensively consider durability, stability, and climate adaptability
1、 Comparison of Wood Properties (Recommended Selection)
White oak
The air dry density is 780 kg/m ³, with strong corrosion resistance (including the conduit with filling material), excellent deformation resistance, and suitable for long-term use.
The mountain shaped wood grain is beautiful and suitable for high-end residences, but the price is relatively high.
Black walnut wood
Density of 640 kg/m ³, moderate bending strength, strong paint retention, suitable for users who pursue artistic sense.
Attention: Imported materials from North America are expensive, and it is recommended to use water-based paint for corrosion prevention.
Teak wood
Waterproof and fire-resistant (thousand year anti-corrosion), anti termite, excellent stability, but high cost due to scarcity in China.
2、 Climate adaptation plan
Cold regions: Priority should be given to white oak or pine wood (with good low temperature resistance).
In humid areas, it is recommended to use teak or cypress wood (moisture-proof and moth proof)
- Cost effective Choice
Pine wood
The price is affordable, but imported wood with a tree age of over 70 years is required.
Attention: High temperature is prone to cracking, it is recommended to use external aluminum protection.
Larch tree
Strong cold resistance (stable at -50 ℃), suitable for cold regions, and anti-corrosion treatment is required during use.
- Guidelines for Avoiding Pits
Avoid using cedar wood (soft texture, prone to deformation).
The recommended wood thickness is ≥ 16mm, and the profile wall thickness is>1.8mm.
The sealant must be made of EPDM material (temperature resistance -60 ℃~160 ℃)
