Cathedral Ceiling: Check out the ways to Insulate them

A Cathedral ceiling or also known as a vaulted ceiling is the best choice for a ceiling if you have a home that has low or flat ceilings which often makes you feel cramped. You can reduce your energy bills by adding insulation to your house, this is especially true if you have an older house but adding insulation to your newer one can pay off in a few years. 

Cathedral Ceiling Insulation

Cathedral ceilings are lovely but we can only get the best use of them if we insulate them properly to keep the ceiling temperature closer to the temperature of your room. To achieve this, the cathedral ceiling must be constructed with some space between your roof and your house’s ceiling for satisfactory ventilation and insulation. 

It is also vital to keep a note of things such as not exceeding the limit which can result in the wood getting rot. If such things occur, the durability of the roof, as well as the health of family members, will be in jeopardy.

Batted insulation proves to be one of the best methods to construct such a cathedral ceiling.

There is also another choice for cathedral ceilings termed unvented, sealed, dense-packed, or even hot roof design as the roof is hotter than a normal roof. Though the term hot-roof is misleading as it is not that much hotter comparatively, maybe 1-5 degrees warmer in surface temperature. Let us know what this term hot-roof is.

The hot roof is not how it sounds, instead, it is a different type of ceiling in which there is no prerequisite of ventilation as the attachment of insulation is done directly with the sheathing of the roof.

Types Of Ceiling Insulation

The vital motive behind the construction of a cathedral ceiling insulation is to ensure a completely sealed roof assembly. Such kind of construction can achieve by the following two options, mentioned below:

  • Vented Batt Insulation.
  • Unvented spray-applied Insulation. 

Cathedral ceilings which are constructed using 2×12 roof joists allow sufficient space for the fiberglass batt insulation and a gap of 1.5” for ventilation. The air can easily flow up the soffit vent, through the insulation baffle and pass through the ventilation gap between the roof casing and insulation, then proceed to exit through the ridge vent. 

By using spray foam insulation, the second-best option, the insulated space top, which results in not needing the venting as the air movement top. As the nature of this type of insulation is providing better insulation, it helps in making the ceiling more airtight.

Open cell-foam consider a good utility if you want to insulate vented cathedral ceilings.

How You Can Do It:

  • While framing the roof of your cathedral ceiling, use 2×10 timber for your roof beams. Some of you might feel a bit inconvenient as why the conventional 2×12 ones did not use. They are not used because they give an extra amount of depth which is quite unnecessary. 
  • Make sure that your roof sheathing is to the top. So, it can meet on both sides of the crested beams. Make sure that there is no space left between those two.  
  • Run functions such as plumbing vents and furnace flues. This will make sure that the exterior surfaces of the roof completely flash. Hence, will make sure about the quality of the work. 
  • You can also cover the roof area with roof paper while using an ice and water shield 3-4 feet up from the eave (rain gutter). 
  • Apply any roofing material that you like. Various types of items that use are clay tiles or even asphalt.
  • Fill up the space between the top plate of the wall and roof covering with a piece of inflexible foam board, on the inside of the roof. 
  • Trim back the spare to hang your drywall after spraying in foam insulation. 
  • Use foam gaskets to seal any electric boxes or any other thing that penetrates the drywall.

Things To Keep In Mind:

Track lighting suggests cathedral ceilings, if possible. It may be possible that the requirement of recessed downlights comes up. In such cases, you have to ensure that the recessed lights install in an impermeable manner. It is also vital to note that such things must have proper ratings such as the conventional Insulation Contact (IC).

Also, some talk in the industry that non-vented roof structures would dramatically increase the temperature of the roof. It may potentially reduce their durability over time and their appearance. This is all hoax, as a recent study by the Solar Energy Center located in Florida found that the difference between temperatures of non-vented and vented cathedral ceilings is very minimal. The actual thing that makes an impact on the change of temperature is the Shingle color, not the roof structures. 

The Bottom Line:

This was all about the cathedral ceilings and the proper methods to achieve proper insulation. We hope that this article has served its purpose and will help you. When you decide to construct an airtight and insulated cathedral ceiling, sooner or later. Such ceilings ensure that the energy does not waste and preserve. Adding insulation can surely save you some amount from the energy bills. This trick works well if your home is a bit older.
