What is a Modular Hearth? 

  • It is the most innovative approach to hearth protection.
  • It is designed to solve issues of current production hearth pads - too many options, sizes, shapes, tile selections, freight damage, cracking/discoloring grout, and more.
  • It is a patent-pending hearth pad containing only non-combustible material.
  • It is designed around our patented “Modular Panel” in which we tight set the tile to a patent-pending engineered steel backer panel. Panels are designed to put together with locking strips for a Type 1 (T1) hearth pad or simply laid into a frame for a Type 2 (T2) hearth pad.
  • It is packaged so that the most popular sizes will allow assembly of either a standard shape or corner shape Type 2 (T2) hearth pad.

It is a hearth pad that:

  • ships in a well engineered box designed to protect the hearth pad from damage.
  • is easy to handle – all sizes (except 60" x 60") ship in a 48"L or 36"L x 12"W x 7"H box.
  • 60" hearth pads ship in two boxes – one 48"L x 12"W x 7"H and one 36"L x 12"W x 7"H.
  • is designed so replacement parts can be sent out immediately in the event damage does occur.
  • will continue to provide maximum protection in the event a tile cracks.
  • produces minimal waste and uses no water - Green Manufacturing.
  • eliminates grout with tight set tile.
  • is built only as a Type 2 (T2) modular hearth pad when using the frame.
  • eliminates any worry over whether a Type 1 (T1) or a Type 2 (T2) is needed, thus further reducing the number of SKU numbers.
  • is available as an inexpensive Type 1 (T1) modular hearth pad if used without a frame – available in square or rectangle shapes only.

Modular Hearth Protection System - Frequently Ask Questions

How thick are Modular Hearth pads?

Modular Hearth pads are 3/8” thick.

What size Modular Hearth do I need for my freestanding stove?

The stove you will be putting it under determines the size of the pad. Generally speaking, wood stoves require pads 48” and larger to protect from falling embers. Pellet, gas, electric, corn, oil and propane stoves can be installed on smaller pads. Consult your stove dealer or stove manual for your stove’s specific requirements.

Can I use a Modular Hearth in a corner?

Yes, a Modular Hearth can be used in a corner in two ways.  

1. If the stove is vented vertically, the Modular Hearth can be installed so the front of the pad is parallel to the front of the stove. The triangular area in the corner can be left uncovered.

2. If the stove is not vented vertically, the combustible area under the piping must be covered with noncombustible material.  Order enough panels to fill the area from the corner to the front edge of the pad. The panels and locking strips can be cut to fit into the corner behind the stove.  Please see the installation instructions for directions on cutting your Modular Hearth.

Can I cut a Modular Hearth to fit a specific space?

Yes. Please see the installation instructions for directions on cutting your Modular Hearth.

Can I cut a hole in a Modular Hearth for air intake?

Yes. Please see the installation instructions for directions on cutting a hole in your Modular Hearth.

Can I install a Modular Hearth on carpet?

If there is carpet, cut ½”particle board, plywood or OSB to the same size as the pad. Lay it between the carpet and your Modular Hearth.

Is there a maximum weight I can put on the Modular Hearth?

If the stove weighs 400 lbs or more and the floor is anything other than concrete, cut ½” paricle board, plywood or OSB to the same size as the pad and lay it down under the Modular Hearth. For the strongest installation, the panels should be attached to the ½” board with a bed of Thinset.  The Thinset will fill the corrugations in the Modular panels and increase the strength and rigidity substantially.

Can you make a Modular Hearth using one of the other Hearth Classics colors of tile?

Unfortunately, no. In order to keep the price of the Modular Hearth Protection System products as low as possible, the Modular Hearth is available in a limited number of tile colors.

Do you make custom sizes of Modular Hearth?

We cannot make custom sizes. However you can add any number of panels and then cut the pad to the size you need. The only limitation is that one side can be no more than a 48” panel.

What is your warranty on the Modular Hearth?

There is a 1-Year Limited Warranty against defects in manufacturing. 
It does not cover:

  • Variations in tile size and color
  • Damage from a stove, insert, fire pit, chiminea or other heating appliance requiring Thermal Protection. The Modular Hearth provides Ember Protection only.
  • Modular Hearths installed without proper support. The Modular Hearth must be installed on a solid flat surface.
  • Installation of a Modular Hearth that does not meet the size requirements of the appliance used on it.
  • Installation that does not meet clearance requirements specified by the appliance used on the Modular Hearth
  • Damage caused by sliding or dragging stove or other appliance across the Modular hearth.
  • Damage caused by altering the Modular Hearth such as cutting a panel or creating a hole.
  • Damage from impact or point loading
  • Modular Hearth used in sub-freezing temperatures
  • Damage to pressure-treated decking if underside of Modular Hearth is not painted according to instructions.

Warranty is limited to replacement cost of the product only.  It does not cover costs and expenses incurred with respect to the removal of the defective hearth or installation of the replacement hearth, including but not limited to labor and freight.

How do I clean my Modular Hearth?

Clean you Modular Hearth as you would any tiled surface.

How do I know whether I need ember protection or thermal protection for fire pit or chiminea?

If the fire pit or chiminea require thermal deck protection, the Modular Hearth by itself will not protect a deck sufficiently. The manufacturer of your fire pit or chiminea should supply information about the size and thermal characteristics of protection needed.  If the manufacturer does not supply thermal protection specifications, the most reliable approach is to measure the temperature under your fire pit or chiminea. Obviously, you do not want to do this test on your deck. If you have extra scrap pieces of your decking material, it would be great to put the scrap decking material beneath the fire pit or chiminea for the test. That setup will help you get the most accurate estimate of the temperatures that your deck could be exposed to. You can use an IR (non-contact) thermometer ($25 and up) or a BBQ-type thermometer ($29 and up) that has a temperature sensor that is on a wire. The thermometer needs to be accurate in the range of 100 degrees to around 170 degrees. You can use the BBQ thermometer when barbequing after you get the fire pit or chiminea tested. If you use an IR (non-contact) thermometer, be aware that with some materials, such as shiny metals, the thermometer will not measure correctly.

For decks constructed with composite materials, the decking manufacturer should specify the maximum temperature above which the decking may start to soften.  That temperature is often around 125°F.  The specification may be called “structural temperature range”. 

For wooden decks you should consult your engineer, architect or builder.

Please be aware that the wood under and around the firepit will tend to dry out more than the rest of the deck.  This may result in the wood decking checking or cracking.  Also, it will likely look different than the rest of the deck .

Unfortunately, there is currently no standard that addresses firepits and chimineas with regards to heat protection.  You will need to monitor your deck periodically around and under the Modular Hearth to make sure that everything is OK. 

Because of the lack of any sort of standard, Hearth Classics is unable to warranty anything with regards to thermal deck protection.  The Modular hearth will protect your deck against embers that fall on the Modular hearth, but the Modular hearth may not be sufficient for any thermal protection requirements.  Both firepits and chimineas can radiate and conduct substantial amounts of thermal energy. Please be careful and conservative in constructing your deck protection under and around your firepit or chiminea.

What size Modular Hearth do I need for a fire pit or chiminea?

The manufacturer of your fire pit or chiminea should supply information about the size and thermal characteristics of protection needed. Unfortunately, there is no standard that defines the minimum clearances that are necessary.  At a minimum you need to protect your combustible deck from falling embers and from burning logs that might fall out of the fire pit or chiminea. For fireplaces, the standard, NFPA 211 states that the noncombustible surface must extend at least 16 inches in front of the fireplace opening.  Since a fire pit is all “opening”, some suggest that the deck protection should extend at least 16” in all directions. Again, the final word is the manufacturer of the device.

I have read on other deck pad manufacturers’ websites that their units are fire resistant, not fire proof. Is the Modular Hearth fire proof?

Yes. The Modular Hearth is completely NONCOMBUSTIBLE, and therefore completely FIREPROOF.

Can I leave my Modular Hearth outside all year?

If you live in an area that does not experience freezing temperatures, you can leave your Modular Hearth out all year. The Modular Hearth should not be subjected to freezing temperatures.

Can my Modular Hearth be used on any type of decking?

Yes, but if your deck is manufactured from pressure-treated lumber, please see the installation instructions for directions on painting your Modular Hearth Panels.

I understand that some deck and patio pads trap moisture under them and tend to encourage rot of wooden decking materials. Does the Modular Hearth trap moisture like the other deck and patio pads?

The galvanized metal backing of the Modular Hearth squarely corrugated.  The corrugation tends to allow air flow and lessens the moisture that is trapped under the pad.  Some moisture may be trapped under the lower portion of the corrugations, but not as much as a pad that is flat.

Can I used the Modular Hearth under my fire pit in the summer and then use it under my stove in the winter?

Yes, technically, you could.  However it would probably not make sense for a number of reasons: 

  • It would be a lot of work, especially moving the stove. 
  • The sizes needed for each application are probably different.
  • The thermal requirements could also be different.
  • Moving the Modular Hearth also increases the potential for damage to the pad, the stove and the pipe.
