HG-Grid Frequently Asked Questions

What is the minimum drop for HG-Grid?

The minimum drop for HG-Grid is 4 inches. This is to allow you enough room to slide and drop the tile in place. If a smaller ceiling height drop is required, reference our CeilingMAX product, a surface mounted ceiling system.

What kinds of tiles can I use with HG-Grid?

With the HG-Grid system, any 15/16-inch 2×2 or 2×4 flat or revealed tile can be used. (Revealed panels are those with the 1/4-inch lip around the edge of the panel). ACP’s Fasade panels can also be used with the HG-Grid system.

What kind of application is HG-Grid recommended for?

HG-Grid is recommended for basements, bathrooms, dining rooms and kitchens. Since HG-Grid is made of PVC plastic, the grid will not rust in high humidity areas.

What kind of lights can be used with HG-Grid?

Any type of recessed lighting can be used with HG-Grid. However, any type of lighting you choose to use, must be mounted to or suspended from the floor joists and NOT the ceiling grid. Since HG-Grid is made of PVC plastic, the grid cannot withstand the weight of the lighting without bending the grid components.

What is a dry line?

A dry line is a string line run from one end of the room to the other. It is an alternative to snapping chalk lines. In such cases where you need to snap a chalk line to align your cross tees, you may need to run a dry line if the cross tees fall between the floor joists instead of on a floor joist.

In which direction do my mains need to be installed?

The HG mains can be installed in either direction. If 2’x4′ trouffer lights are being used, the mains should be installed parallel to the side of the light.

What tools do I need to install HG-Grid?

To completely install HG Grid, you will need the following tools:

  • String or Chalk Line
  • Drill with Phillips Tip
  • Tape Measure
  • Tin Snips
  • Utility Knife
  • 1” Dry Wall Screws
  • Hanger Wire & Lag Eyes

Do I need to align my room to have equal border tiles?

The Room Planning section of the installation guide goes through step-by-step instructions on how to lay out your room with equal border tiles, giving you a more professional look. However, you do not necessarily need to have equal border tiles. You can start a room with a full panel and cut tiles only on one side.

How do I install the wall brackets on inside corners?

To install the wall bracket on an inside corner, you can either abut the two wall brackets together, or you can miter them at 45 degrees.

Can I order more connector clips if needed?

Each HG-Grid main comes with one connector clip. The connector clips attaches the end of one main to the beginning of another. The connector clips that are included with the mains should be sufficient to finish your room. However, if more connector clips are needed they can be purchased through the store from which the HG product was originally purchased.

How do I cut border panels if I’m using a revealed tile?

On the revealed panels you will notice a ¼” lip around the edge of the tile. If you need to cut a border panel, you first need to cut the panel down to the border size you have calculated. To do this measure from the wall to the front edge of the cross tee. Then, lay the tile on the grid. Score the face of the tile along the edge of the wall bracket and pull the tile out of the grid. Run a utility knife along a straight edge cutting into the tile. Then cut into the side of the panel dropping out the corner of the tile.

How does the cross tee attach to the wall bracket?

The HG tee is not attached to the wall bracket in any way. It simply rests on the leg of the wall bracket.

Can HG-Grid be used outdoors?

Yes. We recommend using white HG-Grid components only to prevent color corrosion. Outdoor use of the product must be restricted to installations 1000 square feet or under. Installations over 1000 square feet incur too much expansion and contraction due to weather changes.
