Rockwool Ceiling Panels

Insulating stone wool core

The high density rockwool insulating core offers excellent resistance to fire and heat transmission. The rock wool we use is biodegradable and does not contain or release hazardous substances for health and the environment

Essential features:

Density, 100 kg/m³ (and 120 kg/m³ on request)
Thermal conductivity λ, 0.033 W/mK
Reaction to fire, non-flammable, class A1

Sheets

Pre-painted and galvanized steel sheets of 0.50 mm thickness are usually used. It is possible to choose a sheet of different materials and thicknesses.

Pre-painted and galvanized steel or with aluzinc protection, according to EN 10346 & EN 10143, from 0.35 mm to 1.0 mm, with Polyester, Plastisol, PVDF coatings.
Aluminum, unpainted with aluzinc protection or pre-painted with AluZinc protection, according to EN 508-2, with a thickness from 0.35 mm to 1.0 mm.
Stainless steel, AISI 304 2B or AISI 316 L, from 0.35 mm to 1.0 mm, without color coating, mat or gloss.

Outer Sheet

External metal sheets of trapezoidal cross-section 42/250 (five peaks), with a slight groove (Box) between the peaks. Usually the sheets used are unprinted, but there is the possibility of embossing.

Inner Sheet

Internal metal sheets with no flat configuration (Flat) or with slight groove configuration Box 83 (39-44). There is the option of perforated pre-painted and galvanized steel sheet, with a color coating of Polyester RAL 9002 or Polyester RAL 9005.

Classic Polyester paint

Polyester paints are the most widespread, common and the most economical laminate coatings. They are suitable for both exterior and interior surfaces. With a nominal coating thickness of > 20μm they have very good resistance to external environmental conditions.

Durable Plastisol paint

The Plastisol coating is extremely resistant to outdoor weather conditions. It belongs to the category of “self-healing” coatings in mechanical damages. With a nominal coating thickness of 200μm, it is suitable for external applications where the requirements for strength are high.

High demand PVDF paint

PVDF paint is suitable for buildings with architectural applications where texture and color retention are important. The nominal thickness of the coating is 50μm and it is classified in category s1, in terms of its reaction to fire.

Coating color options

An extremely large number of coating color options are available. Please ask us about available colors (RAL1014 to RAL 9010).

* Panel weight (kg/m²) was calculated considering a core density of 100kg/m³, and a nominal thickness of the laminates of 0.50mm / 0.50mm.

** The thermal permeability coefficient was calculated taking into account the core density of 100kg/m³, the thermal conductivity coefficient of the core of 0.033 W/mK and the nominal thickness of the sheets 0.50mm / 0.50mm.

*** The fire resistance index results from tests carried out in notified laboratories, according to EN 13501-2 standard.

Rockwool ceiling panels are fixed to the load-bearing body by the standard method of visible anchoring.

They are designed to cover roofs with a slope of no less than 10%. On roofs with a greater slope it is recommended to install more than one panel in the direction of the slope. In this case the panels must have an overlap configuration. The cross overlap can be right or left depending on project specifications. The length of the coating varies from 50mm to 300mm. The panels are usually supplied without cross-lamination and the cut-out (removal of part of the inner lamina and core) is done at the project site.

The special joint design of the panels in combination with the use of sealants minimizes the joints from panel to panel and therefore achieves:
