It is a very good idea to find a reputable specialist contractor who guarantees his work (did I say guarantee? Some people do provide them you know). It does have a couple of downsides in that it is soft so paint doesn’t stick to it very well and, owing to its high melting point (2,000 degrees C), smelting it takes a lot of electrical energy.With unusual shapes and no written instructions you may find that the people assembling your windows and doors don’t know how they are meant to go together. Aluminium is the third most abundant element in the Earth's crust after oxygen and silica. It also resists corrosion (sorry that’s not true) in fact it corrodes quickly forming a dense layer of oxide (aluminium rust if you will) on its surface which protects the metal underneath from further corrosion.Window and Door FramesWhen we make window and door frames from wood we have to cut grooves and slots in the wood to hold the glass or form a draft seals, these slots and grooves are costly and wasteful. A well designed aluminium section has these slots already formed plus additional slots for hidden screws, rubber sealing strips or felt draft excluders.7. Anodising also makes the surface porous so it can be stained in a useful range of colours such as black, bronze, blue, gold, red, yellow, etc. Doors should not catch the floor. This makes it a little tricky to weld but with modern welding techniques (mig and tig) this is easily overcome. Anodising is an electrical treatment which increases the amount of aluminium oxide (corrosion) on its surface. Good fit of the window into its frame with effective rubber seals.
Well designed window frames are self draining, they collect water that penetrates and allow it to drain out in a controlled manner. Sikaflex is much better. The results can be variable depending on the skills of the people making them.5.Things to watch for when using Aluminium for Windows and doors. Inspect for dents and scratches and ask the installer to replace poor quality work. Effective hinges that won’t rust. Accurate corner joints.3.Advantages of AluminiumSo what is all the fuss about? Well, as the aircraft industry proves, aluminium it is a very useful metal.10. This oxide layer provides a hard, wear resistant surface that protects the metal underneath from further corrosion and also provides a surface roughness which makes it easier to paint. And here we come to why it is being used to make frames for windows and doors. I recently came across dozens of doors made for a large project that had been assembled by 3 different crews, they had all used different methods but in fact none were assembled correctly.In Indonesia windows and doors are very rarely made to standard sizes and so aluminium frames are usually tailor made on site.2. It never meeds to be rubbed back and repainted, it won’t rot in the rain and, unlike wood, it won’t swell as it gets wet or twist and warp as it dries out.For me personally aluminium is a very poor substitute for the aesthetic beauty if natural wood but the trees are rapidly running out, to say nothing of the loss of Semi Sheer Curtain Fabrics for Sale our natural environment, and so aluminium presents a very viable and useful option.Aliminium is replacing other materials for all sorts of uses particularly in the building industry.
Low MaintenanceThe final benefit is a big one - very low maintenance.ae/contact/. It is light, strong, easy to form and machine, low cost and, by anodising the surface, can be made corrosion resistant and is very plentiful. Effective way of replacing broken glass. Doors and windows should not catch their frames.https://zealcon.A Wide Range of Extruded SectionsAluminium is supplied in a range of very useful extruded sections ranging from simple round tubes to complex sections used for specialist purposes such as curtain rails, car roof racks and artificial insemination equipment for giraffes.Anodised surface treatment for strength and colourAluminium is usually supplied “anodised”.It is made by smelting bauxite at very high temperatures in electrically powered smelters which use very large amounts of power. It is light in weight, it is soft and malleable making it easy to form, machine and extrude but is rigid enough to be used for lightweight structural purposes such as aeroplane frames (as long as its use is correctly designed). Locks and catches all working correctly (lever catches are better than the lift up ones).
A case of severe water damage to a wall on a building in Serangan was traced back to rain beating against an exposed wall getting into aluminium window frames through the corner joints and from there into the structure of the batako wall.Aluminium Windows and Doors - A ChecklistThings to check for in the construction of aluminium window and door frames are:1.6.4.9. Properly constructed, this is particularly important if the door has louvres or “plank” panels.It is important to make sure that they are assembled correctly. At the start of the second world war we had biplanes made from plywood, canvas and string but by the end of the war, a mere five years later we had monoplanes made from aluminium.Another thing to watch for is that they are waterproof. Aluminium has certainly revolutionised aircraft.It also conducts heat and electricity very well and so it is being increasingly used to replace copper for pipes and electrical wiring though while it is not as effective as copper, it is far, far cheaper.On top of all this aluminium is cheap, it is after all the most common element on our planet after oxygen and silicon. Silicone may be used to seal up the window frames but it doesn’t stick very well. Good fit of window and door frames into the walls and with effective corrosion resistant screws.Aluminium is a very useful metal. It all goes down to the design of the frames and the method and accuracy of manufacture.
