Exterior crown molding is a type of trim work that’s used to enhance architectural features of exterior homes, such as windows, doors, and columns. It is usually made of durable materials such as PVC, aluminum, or wood, and comes in a variety of styles and sizes.
Exterior crown molding is primarily used to bring visual balance to the overall design and provide additional, decorative detail. It also helps create a more polished, luxurious look to the exterior of a home or business.
When properly installed, crown molding can add a sense of elegance and unified architectural fashion to any property.
What are the different types of crown molding?
There are a variety of different types of crown molding, ranging from traditional to modern styles. Traditional crown molding is characterized by thick, ornate moldings, typically made from wood. For a more updated and modern look, people often choose thinner, less ornate profiles.
Some of the main types of crown molding include:
• Egg and Dart – This type of crown molding has two parts: a central shaped like an egg and a surrounding profile shaped like a dart. It is a very traditional, classic look.
• Ogee – This type of crown molding has a curved, S-shaped profile. It is a popular, semi-traditional look.
• Cove – This type of crown molding also has an S-shaped profile, but it is more rounded than the ogee.
• Step – This type is made of two or more sections, one above the other.
• Medallion – This type of crown molding can be curved or angular and is typically used to frame a wall or ceiling fixture.
• Straight – This type of crown molding has a traditional, flat profile that can be used to enclose an area.
• Flexible – This type of crown molding comes in several flexible profiles, allowing for an easy installation.
In addition to the types of crown molding, there are also several different materials it can be made from, such as wood, polyurethane, composite, or plaster. The choice of material depends on the look you are trying to achieve and your budget.
What is a cornice on a house?
A cornice is a decorative molding found along the top of a house, typically beneath the eaves of the roof. They can form part of the cornice of the building, which is the finishing trim work along the top edge that provides a transition between the walls and roof line.
Cornices also help to keep water and other elements away from the building and provide a space for ventilation as well as insulation. There are different types of cornice, depending on the building style, with the Classical style having a sharp square face and the more rounded cornices of the Gothic Revival style.
Cornices can be made from wood, stone, brick, or plaster and can feature dentils, brackets, running trim, or any other type of decorative pattern.
How do you build an exterior cornice?
Building an exterior cornice requires planning and knowledge of building materials and construction techniques. First, you will need to decide on the design of the cornice, taking into account the architecture and look of the house as well as its size and shape.
If needed, consult with an architect or a knowledgeable contractor to help you determine the right look.
Once the design is set, you will need to collect the materials: dimensional lumber, sheathing, nails, flashing, trim material, and exterior siding. Make sure to choose high-quality components that will last the test of time.
You will need to frame the cornice using the lumber, usually 2x4s. Then, apply the sheathing, capping it with a layer of flashing along the edges. After that, add the trim (such as crown molding and pilasters/columns) and the siding material.
You will also need to consider the drainage of the area beneath the cornice. Make sure to install a drip cap to direct the water away from the house, and then apply a sealer to make sure the structure is watertight.
Finally, complete the look by adding any decorative brickwork or stucco as desired.
With the right materials and techniques, you can create an attractive exterior cornice that adds value and beauty to your home.
How do you cut an outside Crown Corner?
In order to cut an outside crown corner, you will need to use a miter saw with a specialized blade. First, make sure the miter saw is adjusted to a 45-degree angle. Then, cut the two pieces of baseboard you will use to create the outside corner at the 45-degree angle.
Next, position the two pieces of baseboard on the floor in order to create the corner. Match up the angles and make sure they fit together tightly. The piece of baseboard that is the most visible should be placed on the inside of the corner.
Finally, place the miter saw blade directly above the corner and make your cut. Allow the blade to remain in contact with both pieces of baseboard as you make the cut. Using this method, you should be able to successfully cut an outside crown corner.
What are the angles to cut an outside corner for crown molding?
When cutting an outside corner for crown molding, you need to make two separate cuts at two different angles in order to achieve a professional look. The two angles required are a compound angle that is made up of two angles: a spring angle and a wall angle.
The spring angle must be between 33-45 degrees and is the angle between the two pieces of crown molding. This angle allows one piece of crown to “spring away” from the wall, creating the desired appearance for your corner.
The wall angle must be the same as the angle that the wall makes with the ceiling. To measure this angle, you will have to use a digital crown molding angle finder. This tool will help you accurately measure the walls angle so that you can make your cuts.
Once you have successfully measured both angles, you can then make your cuts. To do this, you will need a saw that can cut at a compound angle (miter saw, compound miter saw, or radial arm saw). You will use the spring angle in order to make your first cut and the wall angle in order to make your second cut.
After making your cuts, dry fit the two pieces together and then secure them in place. Once the two pieces are secured, you will have a professional looking corner that you can be proud of.
How do you cut crown molding for corners on cabinets?
Cutting crown molding for corners on cabinets requires careful planning and calculation to ensure the pieces fit together accurately. Start by taking precise measurements of the cabinet corners. You will need to know the angle of the corner so that you can measure the angles of the miter cuts.
It is important to remember that the flat edge of the crown faces the inside corner of the cabinet, so the angles will be calculated accordingly. From here, you can use a miter saw to make the necessary cuts.
When cutting with the miter saw, make sure the blade is set to the desired angle. Be sure to give yourself enough extra room so you can fine-tune the fit. If the miter cuts require varying angles for the left and right side of the crown molding, use a protractor to get an accurate measurement before making each cut.
Once the miter cuts are made, the pieces of crown molding should fit together neatly in the cabinet corner. Use a small amount of wood glue to secure the pieces together, clamp the joint, and leave it to dry.
How do you figure angles for crown molding?
Figuring angles for crown molding can be a bit tricky, but with the right tools and knowledge, is achievable. To begin with, you’ll need a miter saw with a high degree of accuracy. A power miter saw is ideal for crown molding installation, as it can make precise cuts with each angle.
Once you have your saw, you’ll need to measure the walls of the space where you’re installing the molding. Measure the two adjacent walls, and use a protractor, carpenter’s square, or a combination square to measure the external angle of the wall corner.
You’ll also need to determine the exact center of the corner, as this is the point from which all others will be measured.
With the external angle measurements and the center of the corner determined, you can use calculators that are specifically designed for calculating crown molding angles. You’ll usually need to provide information about the miter and bevel saw, as well as enter in the measurements of the wall.
With that complete, the calculator will output the proper angle to use for the miter and bevel cuts that will make the crown molding fit perfectly.
Keep in mind that you’ll need to make sure that the wall measurements you enter into the calculator are accurate, as an inaccurate measurement will lead to an inaccurate angle. Additionally, many calculators are also capable of calculating the crown molding spring angle (also known as the crown molding reveal angle), which is the angle the two sides of the crown molding should form when the mitered corners are correctly aligned.
This is what gives crown molding its unique shape.
Finally, once you’ve cut both miter and bevel pieces of crown molding to the desired angles, use a quality wood glue to attach the pieces together and finish the installation!
How do you calculate miter angle?
To calculate the miter angle, first use a protractor to measure the angle of the corner where the two pieces of trim intersect. If the angle is right, then you would use 45 degrees. If it is angled, then you will use the given angle in your calculations.
Find the difference between the two angles, and divide it by two. The resulting number is the miter angle. For example, if the two pieces of trim meet at a 105-degree angle, the difference between the two angles is 210.
If you divide 210 by 2, the miter angle comes out to be 105 degrees.
