외부가 어느정도 완성되니까 내부에 스펀지같은게 들어갔다

이 과정은 정말 1~2일만에 전부 다 되었다

 

갑자기 집짓는데 속도가 엄청나게 붙었다

 

골조가 완성되니 내부작업은 정말 뚝딱뚝딱 되는 듯

 

3. Complete Rough Plumbing, Electrical and HVAC

 

During this stage, the following items are installed:

 

Pipes and wires(파이프랑 와이어)

 

 

Sewer lines and vents(씨더, 벤트)

 

Water supply lines(수도관)

Bathtubs and shower units(욕조, 샤워기)

 

Ductwork for HVAC system(냉/난방 배관 공사)

HVAC vent pipes(냉난방 환기파이프)

Electrical wiring and receptacles

Once the shell is finished, siding and roofing can be installed. At the same time, the electrical and plumbing contractors start running pipes and wires through the interior walls, ceilings, and floors. Sewer lines and vents, as well as water supply lines for each fixture, are installed. Bathtubs and one-piece shower/tub units are put in place at this point because there’s more room to maneuver large, heavy objects.

Ductwork is installed for the heating, ventilation, and air conditioning (HVAC) system, and possibly the furnace. HVAC vent pipes are installed through the roof, and insulation is installed in the floors, walls, and ceilings.

After the roofing goes on, the house is considered “dried in.” An electrician then installs receptacles for outlets, lights, and switches, and runs wires from the breaker panel to each receptacle. Wiring for telephones, cable TV, and music systems is included in this work.

Note that HVAC ducts and plumbing are usually installed before wiring because it’s easier to run wires around pipes and ducts than vice versa.

 

각종 전선, 케이블 확인,

내부 벤트(환기구멍), 설치된 것들은

벽을 세우면 구조나 와이어가 어느쪽으로 나오는지 알 수 없다

그래서 미리 가서 사진을 좀 찍어놓고

나중에 extra wire 위치도 확인이 된다

 

이때 매니저가 같이 설명도 해주기도하고

리얼터가 있다면 같이 동행해서

처음 집 짓는 우리에게 뭔가

부족한 부분이나 놓친 부분이 없는지 재확인 받았다

 

지인이 있는 사람은 지인을 데려가도되고

insepctor가 있으면 인스펙터를 고용해서 데려가도된다

4. Install Insulation

내장재(insulation)은 꼼꼼히 들어갔는지

이상한 내장재나 내가 원하는,

그리고 계약된 내장재가 안들어갔는지 확인해야합니다.

 

아래 가이드라인에도 보면

퀼리티가 괜찮은 제품인지 확인해야하는데

이유는 에너지 효율(냉/난방)을 위해서 반드시 확인해야합니다.

 

그리고 R-value(절연값)이 높아야하는데

이유는 전기가 통하게되면 화재위험이 있기때문입니다.

 

 

 

알라바마 지역은 그렇게 춥지않아서

R13으로 하는 경우도 있는 것 같다

 

 

 

 

 

Insulation plays a key role in creating a more comfortable and consistent indoor climate while significantly improving a home’s energy efficiency.

One of the most important qualities of insulation is its thermal performance or R-value(R값/절연), which indicates how well the material resists heat transfer.

 

Most homes are insulated in all exterior walls(외벽), as well as the attic(다락방) and any floors that are located above unfinished basements(지하실) or crawl spaces(지붕이나 지하 좁은공간).

 

 

The most common types of insulation used in new homes are fiberglass, cellulose, and foam. Depending on the region and climate, your builder may use mineral wool (otherwise known as rock wool or slag wool), concrete blocks, foam board or rigid foam, insulating concrete forms, spray foam, or structural insulated panels.

Blanket insulation, which comes in batts or rolls, is typical in new home construction. So is loose-fill and blown-in insulation, which is made of fiberglass, cellulose, or mineral wool particles. Another insulation option, liquid foam, can be sprayed, foamed in place, injected, or poured. While it costs more than traditional batt insulation, liquid foam has twice the R-value per inch and can fill the smallest cavities, creating an effective air barrier.

Fiberglass and mineral wool batts and rolls are usually installed in walls, attics, floors, crawl spaces, cathedral ceilings, and basements. Manufacturers often attach a facing such as kraft paper or foil kraft paper to act as a vapor and air barrier. In areas where the insulation will be left exposed, such as basement walls, the batts sometimes have a special flame-resistant facing.

U.S. Department of Energy Recommended

Total R-Values

 

The following 2008 Department of Energy zone recommendations are based on comparing estimated future energy savings to the current cost of installing insulation. The DOE gives a range for many locations for the following reasons:

Energy costs vary greatly over each zone

Installed insulation costs vary greatly over each zone

Heating and cooling equipment efficiency varies from house to house

Best estimate of future energy costs may not be exact. 1

여기에 미국 지역별로 R-value 값을 찾았으니 확인해보는 것도 좋다.
