Reduce heat loss in your vaulted ceiling

Vaulted ceilings, also known as cathedral ceilings, are a popular choice with homeowners for good reason—they're aesthetically beautiful and create an open, inviting look to your living space. But when they're not insulated properly, radiant heat can easily escape upwards, causing your heating and cooling systems to work harder to maintain comfortable temperatures. Save money on energy bills year-round by installing Double Bubble Reflective Insulation in your vaulted ceiling.

Reflect radiant heat away from your vaulted ceiling

In summer months, radiant heat enters your home through your roof. This causes your air conditioning to work harder, which drastically adds to heating and cooling costs. Reflective Insulation will prevent this by reflecting up to 96% of the radiant heat away from your living space.

Prevent condensation in your vaulted ceiling with cathedral ceiling insulation

As with any residential roof structure, there must be adequate ventilation provided from the eave of the building to the peak of the roof. This is important for proper natural airflow in order to eliminate the opportunity for condensation to form between the roofing materials. The easiest way to ensure a ventilation gap in a cathedral ceiling is to install insulation baffles between each ceiling joist. These are easily stapled to the roof sheeting and they create an airspace that will run continuously from the eave to the ridge.

What you'll need for installation:

  • Scissors and knife for radiant barrier installation

    Scissors or utility knife

  • Insulation tape for radiant barrier

    Insulation tape

  • staple gun

    Staple gun (~3/4" staples)

  • Install radiant barrier with 1-2 people

Waiting to install

I’m waiting to install so no comments available except this. Why wouldn’t you offer the 3” pre-wrap required to reach R8 spec. You offer with other full wrap options. It should be a stand alone option or placed as a kit.

Don,
Thank you for your review! The double bubble product does not have an R value rating. If you are wrapping duct work we offer a specific product which has the R 8 value, EF2280-48-050.
