Choosing the best insulated ceiling tiles is a matter of selecting the tile that keeps with the overall decorative theme of the space and that conforms to your budget. There are vast selections of products that provide different advantages in insulation properties, ease of installation, maintenance and cleaning. If your sole purpose for installing insulated ceiling tiles is to provide greater thermal insulation in order to reduce heating or cooling costs, then the challenge becomes selecting the product with the greatest insulation value that is within your budget for the job. If, on the other hand, the final look of the room is important, then your decision might become a compromise between insulation value, looks and budget constraints.

When choosing the best insulated ceiling tiles, start by looking only at products that are well within your budget. Look for tiles that will cost about 15 percent less than the your budgeted cost for the job. This will allow for wastage, installation errors and other cost overruns.

Insulated ceiling tiles come in a wide variety with different names, including tiles, planks and panels. All of the options provide essentially the same result, but their look and feel can be vastly different. Another important difference is their insulation (R) value, which is a measure of thermal resistance and is calculated using a mathematical formula.

Traditional insulated ceiling tile commonly comes in squares that are 12 inches by 12 inches (30 cm x 30 cm) across and half an inch (1.27 cm) thick. When mounted directly to the existing ceiling, they provide an R value of about 0.68. In addition to their insulation properties, these tiles also might be fire retardant and/or mildew resistant.

The major difference between insulated ceiling tile and insulated ceiling panels is the size of the individual pieces. Typically, panels are twice as wide — 24 inches by 24 inches (60 cm x 60 cm) — and are the same thickness as the tiles. Panels also are available with properties that mitigate mold and fire. The larger panels generally are preferred for larger areas for aesthetic purposes. If you are looking for tiles that will be installed in a large room, you should consider choosing panels instead.

Like insulated ceiling tiles, insulated ceiling planks also provide protection against mildew and fire. The planks come in standard sizes of 84 inches (213 cm) long, 5 inches (12.7 cm) wide and 0.75 inches (1.9 cm) thick. Mounting the planks to the ceiling will provide an R value of about 0.75, and mounting them to the joists will result in an R value of about 1.0.
