Flat white paint

If you do not want to spend a lot on reflective materials, then this is the best one for you. It is ideal for larger rooms. Plants enjoy up to 85 percent of lighting enhancement with this reflector. Flat white paint is better than the white semi-glossy option.

Emergency blankets

You will notice that it is a fragile plastic material. It does not reflect as much light (70 percent) as flat white paint but ideal for radiant heat reflection by up to 90 percent. However, you will want to choose it over others because of affordability and ease of replacement.

Mylar sheets

What Material Reflects Light Best?

From materials that make the best indoor garden reflectors to our top best selections, it is easy to point out those who come above everything else. In more succinct terms, the following should have made their way to your subconscious, not because we believe so, but because there is undoubtedly enough proof already.

  • Mylar sheets (97 percent)
  • Foylon (95 percent)
  • Elastomere, black and white paint (90 percent)
  • Polystyrene (85 percent)

The other materials that haven’t made it to this list do not rate beyond the 70 percent mark, which means they are slightly below par. However, it is imperative to also look at heat energy reflection percentage depending on whether you are buying one during the cold season or you live in the attic climatic range.

Notably, thick materials have a higher heat retention value compared to thinner ones, so they should be well within the range of up 80 to 10 percent heat retention and reflection. Also, take care of those that can melt easily or catch fire like aluminum by regulating the amount of growing room light.
