O que é uma porta interna?
An interior door is a door designed to separate rooms within a home, creating distinct living spaces. Unlike exterior doors, which prioritize security and weather resistance, the primary functions of interior doors are to provide privacy, manage sound transmission, and enhance the aesthetic flow between rooms. The choice of interior door sizes and materials plays a significant role in achieving these goals.
Portas interiores come in a variety of styles and materials. The most common material is wood, but options also include glass, uPVC, aluminum, and composite materials. The selection depends on the desired aesthetic, budget, and functional needs. Understanding which wood is best for interior doors can help you choose the most durable and visually appealing option for your home. Common styles include standard hinged doors, bifold doors, barn doors, and pocket doors.

- Segurança: Doors must provide an adequate opening for safe and quick egress, especially in emergencies like fires.

| Tipo de porta | Largura (polegadas) | Altura (polegadas) |
|---|---|---|
| Portas de armário | 24 a 36 | 80 |
| Portas de banheiro | 28 a 32 | 80 |

It is important to note that these dimensions represent common sizes, and variations do exist. It is also important to always double check that the door purchased fits the dimensions you are expecting.
Compreendendo o tamanho nominal da porta
O tamanho nominal da porta is the rounded measurement used for marketing and labeling purposes. For example, a door with an actual width of 35 7/8 inches might be labeled as a “36-inch door.” The actual size will be slightly smaller than the nominal size to allow for easier installation and fitting into the frame.
O que é uma abertura bruta?
O abertura brusca is the unfinished opening in the wall prepared to receive the door frame. It must be larger than the door itself to accommodate the frame and provide space for shimming and adjustments during installation.
Rough Opening Dimensions
Generally, a abertura brusca should be approximately 2 inches wider and 2 inches higher than the tamanho nominal da porta. This ensures enough space for the door frame and proper leveling during installation.
Measuring for a New Door
Accurate measurements are essential when replacing an old door or installing a new one. Here’s how to measure the rough opening:
Replacing a Door Slab: If only replacing the door slab, measure the existing slab’s dimensions directly.
Medida da largura: Measure the width of the rough opening from stud to stud at the widest point.
