Graphite EPS panels for heating system suppliers
The BSM-16 series uses graphite expanded polystyrene for hydronic underfloor heating. These studded boards have a published 600 × 600 mm format and interlocking edges. Compare the three configurations when preparing a distributor order or project quotation.
Choose the complete panel height
- BSM-16: 33 mm total height with a 15 mm insulation layer.
- BSM-16A: 35 mm total height with a 17 mm insulation layer.
- BSM-16B: 38 mm total height with a 20 mm insulation layer.
The insulation layer is only part of the panel height. Allow for the full profile and the specified covering assembly when calculating finished-floor levels. Keep each model separate in the purchase schedule.
Pipe fit must be confirmed: the published table below lists 10 mm pipe entries for this series. The BSM-16 model name does not confirm 16 mm compatibility. Send your pipe outside diameter and required spacing, and request the current model-specific drawing and sample fit confirmation before placing an order.

Request the current technical datasheet, test conditions and applicable units before using the listed thermal or load values in a project specification.
Prepare a bulk quotation
The published package area is 8.3 m² for each model. Confirm usable coverage, pieces per package, packing dimensions and gross weight for the supplied configuration before calculating freight or pallet quantities.
- List BSM-16, BSM-16A or BSM-16B with the quantity or floor area required for each model.
- Provide the pipe specification, circuit spacing and planned floor build-up for compatibility review.
- State the delivery country, destination and any batch or packing-label requirements.
- Confirm minimum order quantity, sample arrangements, lead time and required project documents in the quotation.
Request a graphite EPS panel quotation. Compare the EPS heating panel range and use the supplier checklist to prepare your order requirements.
Installation and other panel options
View the EPS underfloor heating installation overview. Confirm substrate preparation, pipe retention and the specified covering layer for the supplied system before installation.
For other panel formats, review the XPS radiant floor heating board, aluminum XPS radiant panel and XPS foam composite panels. Confirm system suitability separately before substituting a different panel type.
