Week 7- Ceilings

In the reading and PowerPoint, it was mentioned that interior designers don’t deal with roof framing, because that is a structural issue, but we still have to respond to the shape of the roof since it shapes the space inside. The ceiling finish is also part of our job. Cathedral ceilings were the ones I had not thought about in detail. They were popular in the 1970s and make a room feel spacious, but they make it harder to integrate lighting, to heat and cool the space properly, and to keep a sense of the human scale.

Gypsum wall board is a directly applied ceiling and the most common finish in homes. Plaster was used before wall board and is applied in a three-coat system over lath. In historical buildings, plasters were used to make crown molding and ceiling medallions. Suspended acoustical panel ceilings were what I took away most for commercial design. They are the preferred commercial ceiling because they control noise and give access to ductwork, electrical wiring, and sprinkler lines. The panels come in standard 2'x2' or 2'x4' sizes and can be made of wood or metal. I also learned that exposed structure, or an open plenum, needs the ducts coordinated with the HVAC designer, and they are usually painted to match the ceiling. On the sustainability side, Armstrong has a ceiling recycling program that has recycled 55 million square feet of old ceiling material since 1999, which turns a ceiling choice into a question of what happens to the material later.

For different designed ceiling systems, the coffered plaster ceiling was my favorite. The recessed panels add depth and rhythm, and they make a tall room style unique, and it brings attention to a plane often forgotten to the eye, the ceiling. It also shows the craftsmanship the Bezalel slide talked about, since someone had to understand the material and have the skill to build it and integrate it into the ceiling.

For a commercial example, I liked the wood slat acoustic ceiling. It solves a technical problem, noise control and access above the ceiling, while making a commercial space feel warmer instead of cold and institutional. The linear pattern also gives the room direction. My last example was the exposed open plenum ceiling. When the ducts, pipes, and structure are organized and painted in one color, what could look messy becomes a clean industrial look. It also adds ceiling height and makes maintenance easy, but it only works if the designer coordinates with the engineers.

What these examples have in common is that the best ceilings do more than cover the structure. Each one handles a practical need like acoustics, access, light, or scale, and it also adds character to the space. That connects back to the idea that good design takes technical knowledge, an understanding of materials, and skilled workmanship working together with creativity.
