Nine Advantages Of Aluminum Alloy Doors And Windows

1. Light Weight And High Strength

The Density Of Aluminum Alloy Is Only 1/3 Of That Of Steel, And It Is A Thin-walled, Hollow Extruded Profile With Light Weight. However, The Strength Is Close To The General Low Carbon Steel, Which Can Reach More Than 30MPa, And The Wind Pressure Strength Value Of The Casement Aluminum Alloy Window (high Function Window) Is 300Pa~3500Pa.

2. Good Sealing Function

The Sealing Function Of Aluminum Alloy Doors And Windows Is Obviously Better Than That Of Steel And Wood Doors And Windows, Mainly Because Of Its High Processing Precision, Extremely Tight Installation, And The Use Of Rubber Beading And Sealing Materials With Excellent Functions To Seal The Seams.

3. Air Tightness

The So-called Air Tightness Refers To The Air Permeability Of Aluminum Alloy Doors And Windows Under The Condition Of A Certain Pressure Difference. The Detection Method Of Air Tightness Is Usually In A Special Pressure Test Box, So That A Pressure Difference Of More Than 10MPa Is Formed Between The Front And Rear Of The Window, And The Ventilation Volume Per M2 Area In Each Hour Is Measured. For Example, The Air Tightness Of Class A Aluminum Alloy Casement Window Is 0.5m3/(m2 H)~1.0m3/ (m2 H), While The Air Tightness Of Class B (middle Function Window) Is 1.0m3/(m2 H)~1.5m3/ (m2h).

4. Water Tightness

Water Tightness Refers To The Average Pulse Pressure Value That Aluminum Alloy Doors And Windows Can Accept Under The Condition Of No Rainwater Leakage. During The Detection, It Was Also In A Special Pressure Test Box, A Sinusoidal Pulse Wind Pressure With A Period Of 2s Was Applied To The Outside Of The Window, And At The Same Time, 4L Of Artificial Rainfall Was Sprayed To The Window Every Min And Every M2, And A Continuous 10min Wind And Rain Experiment Was Carried Out. There Should Be No Visible Water Leaks On The Indoor Side. For Example, The Water Tightness Of A-type Aluminum Alloy Casement Windows Is 450Pa~500Pa, While The C-type (low-function Window) Is Only 250Pa~350Pa.

5. Insulation Function

The Thermal Insulation Function Of Aluminum Alloy Doors And Windows Is Divided Into Three Levels According To The Heat Transfer Resistance Body (m2 K/W), Namely, I Level ≥ 0. 50; II Level ≥ 0. 33; Щ Level ≥ 0. 25. The Thermal Insulation Function Is Also Known As The Thermal Insulation Function. For Steel Windows, Whether It Is A Solid Or An Empty Stomach, There Is No Requirement For The Thermal Insulation Function.

6. Sound Insulation Function

The Sound Insulation Function Of Aluminum Alloy Doors And Windows Is Usually Indicated By Sound Insulation (dB). It Is A Sound Transmission Loss Experiment On Windows In An Audio Laboratory. When The Audio Frequency Reaches A Certain Value, The Sound Transmission Loss Of Aluminum Alloy Doors And Windows Tends To Be Stable. In This Way, The Sound Insulation Level Curve Can Be Detected. In My Country, The Sound Insulation Function Is Divided Into Five Grades According To The Amount Of Sound Insulation. Aluminum Alloy Doors And Windows Should Be Above 25dB~40dB, Which Is Grade II~V.

7. Good Durability, Easy To Use And Repair

Aluminum Alloy Is Durable And Has No Aging Problems. There Is A Very Thin But Very Strong Aluminum Oxide Film On The Exterior Of Doors And Windows, So It Does Not Rust, Fade, Or Fall Off, Hardly Needs Repair, And The Service Life Of Spare Parts Is Also Very Long. In Addition, Due To The Light Weight Of Aluminum Alloy Doors And Windows, The Precision Of Processing And Installation Is High, So The Opening And Closing Are Light, Flexible And Noise-free.

8. Good Decorative Effect

Color Decoration Is Very Important To The Effect Of Architectural Art. The Appearance Of Aluminum Alloy Doors And Windows Is Treated By Anodizing And Electrolytic Coloring. The Thickness Of The Oxide Film Is Above The Thickness Of The Paint Film, And The Color Is Silver White, Bronze, Etc. The Choice Of Color Is Large, There Are Various Colors Such As White And Green, And Various Exterior Colors Such As Wood Grain And Granite.

9. It Can Carry Out Industrial Production Of Aluminum Alloy Doors And Windows. From The Processing Of Frame Materials And Profiles, The Production Of Seals And Supporting Parts, To The Installation Experiments Of Doors And Windows, It Can Be Organized In The Factory For Large-scale Industrial Production, So It Is Conducive To The Completion Of Door And Window Product Design. Standardization, Serialization Of Products And Generalization Of Spare Parts Have Greatly Improved The Technical And Economic Effects Of Aluminum Alloy Doors And Windows.
