vented attic

Vented Attic

Vented attics are the most preferred options for maximum homes. A vented lof has multiple openings. All these openings are covered with an attic vent window or two so that air can gradually seep into the room. Aside from that, another main purpose of these vents is to let the air crawl out in case of overheating.

Still, heat can build up to 150 degrees. This is why insulation is very crucial inside the space. It is considered as an unconditioned space, which means that temperature is often fickle inside it.


  • Continuous airflow
  • Multiple vents


  • Unconditioned room temperature

You need the right attic windows to properly utilize the ventilation. Here’s my personal recommendations on how to keep the attic cool in hottest summer.

Unvented (Sealed) Attic

Sealed attics, as the name states, do not have openings of any kind for outdoor air to seep in. It’s a reliable option if you do not want to deal with stubborn temperatures. Polyurethane foam spray is commonly used to insulate an attic. The foam allows the air to stay at a specific temperature for a long time.

Usually, sealed attics are 10 degrees warmer. This is why they are considered as semi-conditioned spaces. They can help you save a lot when it comes to energy consumption, and you can move more freely inside the attic.


  • Energy efficient
  • Semi-conditioned room temperature


  • Insufficient airflow
Based on the framing properties attics can also be classified into two categories:
rafters roofing

Rafters Attic

Rafters are popular attic framing method for a long time. It’s engineered lumber pieces, all of which act as the “skeleton” of the roof. When installing rafters, workers cut and plug each stick separately to ensure that your attic will securely hold your house’s roof. Floor joists are installed first, and then the beams are plugged in.

Rafters accommodate enough space for storage underneath. Rafter roofs are also known as “stick-framed.”


  • Sufficient storage space
  • Secure hold on the roof


  • Difficult to install
trusses attic

Trusses Attic

Trusses are like a miniaturized version of rafters. Having minimal storage space, and the sticks are designed in a web-like manner. When trusses are built, they are simply connected from the top to the bottom chords. Trusses are not meant for heavy payload.

Trusses are quite useful for roof support. The web-like design gives a secure hold, which is ideal for added protection. This attic type is also quite effective against unexpected home fires. It holds the roof and gives you enough time to get out of the house.
