Does reflective insulation really work?
Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it’s usually more cost-effective to install more thermal insulation than to add a radiant barrier.
Do I need a vapor barrier in basement ceiling?
2 Answers. If the basement is finished and has no moisture issues, the vapor barrier is not needed. If it has moisture issues, the vapor barrier is probably a problem.
Where should reflective insulation be used?
Reflective insulation and radiant barriers work well in warm climates, particularly in homes with:
- Air ducts in the attic.
- Asphalt roofing (which more easily absorbs heat from the sun)
- Little to no shading from trees.
Which way do you install reflective insulation?
If you’re wondering whether to put the foil side of foam insulation board shiny side in or out, consider whether you want to make the space inside warmer or cooler. If you want to make the space warmer, the foil should face inside so it can reflect radiant heat back into the room.
What type of insulation should I use in my basement ceiling?
Insulate basement ceilings if you’re merely looking to mitigate heat loss and potentially lower your energy costs. They recommend using fiberglass batt insulation, which fits more easily among the many pipes and joists found in most basement ceilings.
When should you insulate basement ceiling?
Insulating the basement ceiling will keep most of the heat upstairs in the living space. As a result, the basement will be colder in the winter making it important to also insulate any water pipes or heating/cooling ducts in the basement.
Can you put Reflectix over insulation?
Reflectix can be used as basement ceiling insulation when precisely stapled to the centers of the floor joists above. The product must be applied tightly, with room for airflow. One benefit of using Reflectix over fiberglass insulation is that Reflectix resists mold and mildew well.
What is reflective insulation for?
Reflective insulation, installed in the attic ceiling, helps reflect sunlight and reduce the radiant heat transfer from the underside of the roof to the other surfaces in the attic. This helps keep your home cooler and more comfortable.
What kind of insulation can I use for my basement ceiling?
Reflectix can be used as basement ceiling insulation when precisely stapled to the centers of the floor joists above. The product must be applied tightly, with room for airflow. One benefit of using Reflectix over fiberglass insulation is that Reflectix resists mold and mildew well.
Can you use reflectix on fiberglass ceiling insulation?
Reflectix can be used as basement ceiling insulation when precisely stapled to the centers of the floor joists above. The product must be applied tightly, with room for airflow. One benefit of using Reflectix over fiberglass insulation is that Reflectix resists mold and mildew well. If it does develop mold and mildew, it can be cleaned off.
What can reflectix be used for in the basement?
So, even though Reflectix functions best with airspaces, there are some applications where it is impossible to add airspaces, such as around pipes, vents, and water heaters. Reflectix can be used as basement ceiling insulation when precisely stapled to the centers of the floor joists above.
What are the pros and cons of reflective insulation?
One advantages of reflective insulation is that it is easy to install yourself. However, it is not recommended for use in cold climates, and may cause moisture problems. Reflective insulation is most commonly used in attics rather than basements.
