The capping or cladding on a window is a material, usually vinyl or aluminum, covering the window’s wood frame. As long as it is applied to the window, it will prevent the wood from being exposed to the elements, ensuring it will continue to perform well for many years. Wood exposed inside your home after being covered by cladding outside is a subtle design feature of your home’s interior. This guide is all about aluminum capping in detail.
Aluminum capping
“Aluminum capping” is also known as “aluminum cladding” and “aluminum wrapping.” The capping process involves applying aluminum sheeting over wood trim that is cut and formed. This product often frames a wooden window frame and door frame area of a house or building.
Although the concept of capping is relatively straightforward, installing it can be pretty challenging.
A perfect fit must be achieved between the aluminum sheeting and the contours of your house. It is done with the use of a brake, which is a machine that bends sheet metal.
When aluminum capping is not installed correctly, it can make your house’s exterior look uneven and therefore detract from its beauty.
How to Paint Aluminum capping?
To paint aluminum siding successfully, a little preparation is necessary.
Make sure the surface is clean.
Rust-resistant aluminum accumulates a chalky-like dust substance that must be removed before painting can begin in earnest. It would be helpful if you cleaned the surface thoroughly enough to pass a white glove test – chalky dust is a residue of factory powder coating, and unfinished aluminum oxidizes easily. If you want to clean the siding thoroughly, a power washer will produce the best results. Using a TSP solution and bleach will help you achieve the level of cleanliness you desire.

The surface must be primed.
The purpose of priming is twofold: first, it stops oxidation from occurring, and second, it provides an even, uniform surface on which to apply the paint. The best method is using self-etching paint designed for painting metal. To get to the aluminum surface, you need a primer that can penetrate the surface and cut through the oxidation. Some stains claim to contain a primer in their two-in-one mix, but they don’t. It may be adequate to use 2-in-1 colors inside, but they fail miserably outside.
Apply Paint
Two methods are available to apply paint – with a brush or with a sprayer. You should use small amounts of paint when painting in the sun if you are using a brush. Aluminum will heat up, and the color will set quicker. Too much coloring can result in uneven finish variations, which create a sloppy appearance if you roll the paint on too thick. The best way to get the right amount of color in the right place is to use an airless sprayer that a professional painter uses, and you should hire a professional for the task.
Pros of Aluminum capping
· Thermal Performance
When energy-efficient glass is combined with aluminum windows, thermal and sound insulation can be achieved that meets or exceeds energy efficiency standards, thus providing greater value than wood and uPVC windows that require less effort and are less expensive. With aluminum windows, heat can be quickly gained and lost by nearly 60%. They are also one of the most environmentally sustainable metals due to their high recycling rate.
· Cost-effectiveness
Compared to wooden frames, aluminum windows are significantly less expensive, making them a great economical alternative for commercial and residential purposes. As well as being easy to manufacture, they are a cost-effective and ideal alternative to windows due to their affordability and ease of manufacture.
· Maintenance and durability
Aside from having a very long life, aluminum windows are highly resistant to the effects of the outside weather. Since aluminum is corrosion-resistant and anti-rust, its finished condition can be left in its dead condition for virtually no maintenance. Their long lifespan is further enhanced because they are less likely to warp, rot, swell, or crack over time. Furthermore, with a damp cloth, they can be cleaned quickly and don’t require the expenditure of periodic or annual paints or polishes.
Cons of Aluminium capping
· Condenses inside and loses heat
In cold climates, aluminum windows may not perform well since heat will be lost through the frame as aluminum is an excellent thermal conductor. Additionally, aluminum frames are susceptible to condensation or frost formation on their interior surfaces, posing many problems.
· Corrosion and oxidation
With time, aluminum frames can rust due to oxidation, a natural phenomenon. In aluminum windows, oxidation occurs over time, resulting in white residue and cavities. Also, aluminum is susceptible to corrosion if proper measures aren’t taken to control electrolysis.
· Visual appearance
Window frames made of aluminum are generally less attractive than wood frames. The look of wood is commonly more natural and refined than that of aluminum, which can appear unnatural and unrefined. Though aluminum comes in various colors and styles, it can be customized to match any décor.
FAQs (Frequently Asked Questions)
How does aluminum window capping work?
To prevent water from infiltrating your windows, aluminum is applied as a weather-proof layer. You don’t have to replace the wooden window frames and exterior trim entirely because they are already there.
Is it possible to paint aluminum cappings?
Paint adheres much better to aluminum than vinyl, and aluminum accepts paint well. Wood shrinks and expands as it ages, and aluminum doesn’t suffer from this problem, so you won’t see cracks or peeling paint like you would with wood.
Is aluminum a cost-effective way to cap windows?
It costs about $1 to $2 per linear foot to wrap an aluminum window, plus $70 an hour for labor. The cost of the unit and the work for a 5-by-3-foot window is about $150. Wood that is aging is protected from moisture and harsh outdoor conditions with aluminum wraps.
What is the purpose of window capping?
With exterior trim caps, you can boost the look and durability of wooden pieces without replacing them altogether. By installing capping over your window frames, you increase the seal between your windows and walls, protecting you from leaks and water damage.
How does capping for garage doors work?
To make our door and window frame weatherproof and attractive, we cap them. The metal sheathing, or “capping,” that covers the structure of your garage door can be repaired or replaced if it has been damaged or looks rough. As a result, the door frame will look brand new, and you won’t have to paint it.
Which material is best for exterior trim?
In terms of exterior house trim, wood is the most classic choice. There are solid wood and composite options available. Because wood trim feels and looks natural, it is popular with many homeowners, but due to a shortage of quality wood products, it has become more expensive.
