Funtek porcelain honeycomb panels use a 3–6 mm ceramic face and are available in composite sizes up to 1200 × 3200 mm. The documented complete wall-panel weight is approximately 9–16 kg/m², equivalent to about 1.84–3.28 lb/ft². At 1200 × 2800 mm, that range gives approximately 30–54 kg per panel. Porcelain honeycomb panel thickness is specified by the face and backing combination: the wall example is a 3 mm face with a 9 mm PU fiberglass-faced aluminum-honeycomb backing.

Panel Sizes and Configuration Examples

Start with the application and compare the face and backing thicknesses separately. The wall, exterior embedded-fixing and floor examples below use the same type of PU fiberglass-faced aluminum-honeycomb backing, with different layer thicknesses for the stated application.

The stated maximum composite size is 1200 × 3200 mm. The 1200 × 2800 mm format used for the wall-weight example is a separate size, with an area of 3.36 m². Put the required finished width and height on the project schedule; the maximum-format figure describes the available size range.

The approximately 9–16 kg/m² range describes complete ceramic-faced wall panels across configurations. It does not assign a particular weight to each row above. A configuration-specific quotation should state the weight of the chosen face, backing and finished dimensions together. The Funtek panel specification overview and dimensions and weight page of the technical guide provide the corresponding product reference.

Wall-panel example: 1.2 × 2.8 m = 3.36 m²; 3.36 × 9–16 kg/m² = 30.24–53.76 kg, approximately 30–54 kg.

Maximum format and project panel dimensions

A facade drawing usually contains several finished piece sizes around corners, openings and changes in elevation. Record those sizes individually, even when they come from the same maximum-format panel. Quantity, pattern direction and the location of fixing details must follow the same panel references.

An installed elevation contains defined panel edges and joints, while a large interior panel must fit its assigned wall position. Those positions establish the finished piece dimensions to enter on the schedule. For the process of turning an elevation into numbered pieces, use the sintered stone facade panel layout article.

Face Thickness, Backing Thickness and Complete Panel Thickness

The ceramic face is the visible porcelain or sintered-stone surface. The backing comprises the aluminum honeycomb core and the PU fiberglass skins on its upper and lower sides. An adhesive layer joins the ceramic face to this formed backing. The porcelain honeycomb panel construction and backing comparison explains those components in detail.

What a 3 + 9 mm construction means

In a 3 + 9 mm description, 3 mm identifies the ceramic face and 9 mm identifies the complete honeycomb backing. Their nominal combination is 12 mm. The 9 mm backing dimension already includes its PU fiberglass skins; adding separate skin thicknesses to that number would count them twice.

Keep “3 mm face,” “9 mm backing” and “3 + 9 mm nominal construction” as separate descriptions in a specification. They identify the components and make a quotation easier to compare. The nominal sum is not a finished-thickness tolerance: the exact bonding-layer thickness and manufactured tolerance need to appear in the dimensional information for the selected panel.

Panel thickness and installed wall depth

The complete panel occupies only part of an installed wall detail. Rear fittings, rails, brackets and the cavity add depth behind it. When a wall opening or return has a fixed clearance, provide both the required panel construction and the available distance from the support to the finished face.

A Funtek wall detail also includes a 2700 × 1200 × 3 mm face with a 2700 × 1200 × 9 mm backing. This is another nominal 3 + 9 mm example, using a different height from the 1200 × 2800 mm weight example. Retaining both dimensions in their own drawing or schedule prevents a size from being carried into the wrong calculation.

Complete-Panel Weight per Square Meter and Square Foot

Porcelain honeycomb panel weight is most useful for comparison when it is expressed per unit of finished panel area. The Funtek wall-panel range of approximately 9–16 kg/m² includes the ceramic face and the honeycomb composite backing. The appropriate point within that range depends on the selected construction.

Metric specifications and rounded U.S. reading equivalents
Item Metric value Rounded U.S. equivalent
Stacked porcelain honeycomb panels with exposed face and backing layersComplete wall-panel areal weight Approximately 9–16 kg/m² Approximately 1.84–3.28 lb/ft²
Maximum composite size 1200 × 3200 mm 47.24 × 125.98 in
Wall-weight example size 1200 × 2800 mm 47.24 × 110.24 in
Typical ceramic face 3–6 mm 0.12–0.24 in
Wall backing example 9 mm 0.35 in
Exterior embedded-detail backing 12–15 mm 0.47–0.59 in

For areal weight, multiply kg/m² by 0.204816 to obtain lb/ft². Thus 9 × 0.204816 is approximately 1.84, and 16 × 0.204816 is approximately 3.28. For dimensions, divide millimeters by 25.4 to obtain inches. The metric values remain the primary specification; the rounded equivalents make them easier to read in a U.S. project discussion. The NIST SI conversion tables list the corresponding unit relationships.

Backing-only weight and complete-panel weight

The furniture example describes a 15 mm honeycomb base panel weighing approximately 2 kg/m². That figure is for the base panel before the ceramic face and decorative rear material are added. It cannot be entered as the weight of a finished ceramic-faced wall panel.

PU fiberglass-faced honeycomb backing is a separate component before the ceramic face is added.

The reinforcement example adds approximately 2 kg/m² to the same bare 3 mm face while improving bending and breaking performance. That is a small weight addition used to make a fragile face easier to handle as a reinforced assembly. Replacing the documented thicker solid slab is a different comparison and reduces complete-panel weight. See the comparison with a thicker solid slab for those two selection routes and the mechanical performance article for the reinforcement results. For the wider distinction between face, finished panel, installed system and shipping weights, see ultra-light large-format sintered stone panels.

A composite also cannot be assigned the mass of solid ceramic at its full nominal thickness. A 3 + 9 mm build-up contains a ceramic face, PU fiberglass skins and an aluminum honeycomb core. Use its stated complete-panel areal weight or the confirmed weight of the selected configuration.

How to Calculate the Weight of One Panel

Multiply the finished panel area by its areal weight. When dimensions are given in millimeters, convert both width and height to meters first:

Panel area (m²) = width (mm) ÷ 1000 × height (mm) ÷ 1000
Panel mass (kg) = panel area (m²) × areal weight (kg/m²)

Worked example: 1200 × 2800 mm

A 1200 × 2800 mm panel is 1.2 × 2.8 m. Its area is 3.36 m². Applying the documented complete wall-panel range gives:

  • At 9 kg/m²: 3.36 × 9 = 30.24 kg.
  • At 16 kg/m²: 3.36 × 16 = 53.76 kg.

Rounded to whole kilograms, the result is approximately 30–54 kg per panel. This agrees with Funtek’s 1200 × 2800 mm wall-panel example. It is a preliminary range across constructions; choosing “3 + 9 mm” alone does not establish an exact weight within that range.

Estimate the Weight of a Rectangular Panel

Enter the panel dimensions in millimeters. Use the stated wall-panel range, or enter a confirmed complete-panel weight per square meter.

Panel area: 3.36 m² (36.17 ft²)

Estimated net panel weight: 30.24–53.76 kg (66.67–118.52 lb)

Calculated from the stated 9–16 kg/m² complete wall-panel range; approximately 30–54 kg per panel.

The calculation uses a rectangular panel area. Packing and separately quoted fittings are additional. Use the selected configuration and actual piece geometry for the final panel schedule.

Use the same formula when the required width or height changes. The maximum 1200 × 3200 mm format has an area of 3.84 m², but the weight entered on an order should correspond to its selected construction. A larger area increases the estimated mass at the same areal weight; a different backing or face can also change that areal weight.

The product’s 12 mm solid ceramic wall-panel reference weighs 28 kg/m², or 94.08 kg over the same 3.36 m² area. The calculated PU composite range of 30.24–53.76 kg reduces net panel mass by about 40–64 kg per piece. That difference matters when moving full-height pieces through a building, holding them at the support and planning the load carried by the facing. The installation and crew comparison connects these weights to the documented hanging arrangements.

How Application Changes the Initial Build-Up

For the M8 embedded-nut and interior riveted-clip arrangements, see porcelain honeycomb panel installation and fixings. Keep the selected connection with its panel reference and backing thickness.

Wall panels and exterior embedded fixings

The 3 + 9 mm wall example starts with a thin ceramic face and a formed honeycomb backing. The exterior embedded-nut detail instead identifies a 3–6 mm face with a 12–15 mm backing. The difference in the backing dimension belongs with the connection detail, so an exterior panel schedule should identify whether the fixing is embedded or uses a riveted rear fitting.

Keep that fixing choice attached to the panel reference and thickness combination. A specification reading only “15 mm panel” leaves open whether 15 mm describes the backing, a nominal face-plus-backing combination or the depth of another component. The separate columns in the configuration table resolve this at the initial selection stage.

Floor combinations and the separate 51 kg example

The floor construction examples use a 6 mm ceramic face with a 9 mm or 12 mm PU honeycomb backing. These give nominal 6 + 9 mm and 6 + 12 mm combinations, or nominal sums of 15 mm and 18 mm respectively. The backing, ceramic surface and floor support form parts of the specified floor assembly.

For a continuously supported floor, the composite flooring build-up and installation guide connects these dimensions to the leveling and adhesive layers. Heated floors and raised access floors use different layer positions or supporting systems and need their own sections.

Funtek’s floor comparison gives a 1.2 × 2.7 m panel with a 6 mm face and 9 mm backing at 51 kg. Record that complete set of dimensions and layers with the stated mass. The footprint differs from the 1.2 × 2.8 m wall example, and the figure applies to that particular floor example.

For initial selection, choose the application row first, then provide its face thickness, backing thickness and required finished dimensions together. Floor orders should use their selected configuration’s weight. The complete wall-panel range remains a wall-panel reference, while the 51 kg floor example remains its own documented combination.

How to Compare Two Panel Quotations

Compare quotations using the same material, thickness and dimensional basis. “Porcelain honeycomb panel” identifies the product family, but it does not specify the face thickness, backing skins, backing thickness or finished piece size. Each of those fields helps establish what is included in the quoted panel.

Write the backing as PU fiberglass skins with an aluminum honeycomb core, then give its thickness. Follow with the ceramic face thickness and finished dimensions. Ask for the complete-panel areal weight and net weight per piece on that same basis. A quotation for a bare honeycomb substrate cannot be compared directly with one including the ceramic face and rear fittings.

The rear fitting and its rivets are visible on this panel sample; fixing requirements belong in the configuration schedule.

List cutting, openings, edge treatment, embedded components and riveted fittings as requirements against the relevant panel references. The sample with a riveted rear fitting shows a component that belongs in the scope description; the staged panels show the physical pieces that the schedule needs to identify. Use the same piece references for fabrication and site positioning, with the specified fittings listed against each reference.

Net panel mass and packing mass

Keep net panel weight, attached hardware, crate or packing weight and gross shipping weight as identified fields. State whether a per-piece net figure includes its rear fittings. The product’s kg/m² range cannot supply the crate weight, and multiplying panel area by areal weight does not add packing or freight materials.

For several panel sizes, compare each size and quantity before adding the net panel weights. This makes a quotation easier to check when an elevation contains full-height panels, smaller returns and pieces around openings. The facade specification and RFQ checklist covers the wider information package for a project quotation.

A Panel Schedule to Prepare Before Requesting a Quote

Use one reference for each distinct combination of size, construction and fixing requirement. The example below uses a 1200 × 2800 mm nominal 3 + 9 mm interior wall configuration to show the fields. It is a preparation example, with quantity and project location left for the buyer to complete.

Porcelain Honeycomb Panel Size and Weight FAQs

01

Can I calculate an exact panel weight from the face and backing thicknesses alone?

Use the complete-panel areal weight for that specific construction. The documented 9–16 kg/m² wall-panel range does not provide a separate weight for every face/backing combination. Thicknesses such as 3 + 9 mm identify the layer combination; they do not establish one exact value within the range. Request the corresponding kg/m² and net weight per finished piece with the quotation.

02

Can the rounded inch equivalents be used as fabrication dimensions?

Keep the agreed metric dimensions on the production drawing unless the project and supplier explicitly adopt another dimensional basis. Values such as 47.24 × 110.24 in are rounded reading equivalents of 1200 × 2800 mm. They do not define an extra machining allowance or manufacturing tolerance. State the drawing units and revision clearly when issuing the panel schedule.

03

How should I estimate the weight of a panel with an opening?

For a rectangular opening, subtract the opening area from the overall rectangular panel area, then multiply the remaining area by the confirmed complete-panel kg/m². For example, a 1200 × 2800 mm panel with a 400 × 600 mm opening has 3.36 − 0.24 = 3.12 m² of remaining face area. Show the opening location and attached fittings on the drawing, and use the final net weight for that finished configuration in the panel schedule.

04

How do I estimate the net panel weight for an order containing several sizes?

For each panel reference, multiply its width in meters by its height in meters, the applicable complete-panel kg/m² and its quantity. Add those line totals. When only the documented 9–16 kg/m² wall-panel range is available, retain a lower and upper estimate for the relevant wall panels. Keep packing and gross shipping weight as separate figures supplied for the shipment.

05

Does a 15 mm honeycomb furniture base panel include the decorative surfaces?

The 15 mm, approximately 2 kg/m² example describes the honeycomb base panel. The cabinet-door construction then adds a 3 mm ceramic face and a decorative rear material. Record those components separately when specifying the finished door or furniture panel; the base-panel dimensions do not describe the final decorated assembly.
