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.

See how it works

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

    1–2 people

Great

Bought this to use as skirting for our RV for the winter weather and it’s gonna work great! It’s thick and easy to use. We purchased the tape that’s suggested to go with it and we’re not happy with that. It sticks to the eco foil great but doesn’t stick to other surfaces good. We ended up purchasing actual silver duct tape and it worked great.

Radiant heat barrier

Love the product, shipped quickly. Absolutely great customer service which is becoming a rarity these days. Insulation went down without problem, seam tape went down great. The 4 stars is because something should be done with silver face, when installed with sunshine you will get an immediate tan. Very very bright. I'm not an engineer but I would think something could be done, maybe not. Actually give it 4 and 3/4 stars.

Easy to work with

Everything about his insulation is good. It's easy to work with. Easy for beginners. No mess. Would buy the recommended tape to tape seams together. Easy to cut. Hope it actually works and insulates!.
