Roof Sandwich Panels

ISOTHERM Roof and Wall Panels are composite prefabricated panels, consisting of two layers of metal facers and PUR/PIR insulation core between the facers.

ISOTHERM panels are versatile cladding products, allowing for use in: Roofs, External Walls and Partitions.

Panel thicknesses available range from 40 to 200mm, capable of meeting and exceeding local & International building regulation requirements.

ISOTHERM specialized in production, sales and export of Polyurethane (PU) & Polyisocyanurate (PIR) Insulated Sandwich Panel & Rockwool. Sandwich Panels are produced in a continue line with 3 types of insulation materials including such as, Polyurethane (PUR), Polyisocyanurate (PIR) & Rockwool insulation thicknesses. As external and internal surfaces of sandwich panel painted galvanized, galvalume, Alu-zinc, stainless steel, Painted or natural aluminium/Steel materials can be used.

They are manufactured as polyester, plastisol, PVDF and food safe painted according to the needs of the Project. They can be manufactured in all RAL codes. ISOTHERM Insulated Roof and Wall Sandwich Panels are responding all needs such as thermal insulation, air tightness, hygiene, aesthetics, fire insulation.

Advantages of using ISOTHERM sandwich panels are:

Specifications :

Insulation Core:

The core of ISOTHERM panels is an environmentally sustainable rigid PUR/PIR insulation foam.
available in:-

Having properties as,

The blowing agent used in ISOTHERM panels is environmentally friendly pentane gas with Zero Ozone Depletion Potential (ODP) and Low Global Warming Potential (GWP). It does not contain CFC or HCFC.

Metal Facers:

The standard substrate for Internal and external facers are prepainted and hot-dip galvanised steel.

Variations are possible in the surface material specifications to suite a wide range of specialized applications:

High Durable Polyester coating is suitable for increased resistance against corrosion and harsh whether.

PVDF coating is suitable for external applications where higher resistance against corrosion, colour fading and harsh environment conditions is required.

Plastisol coating is suitable for internal applications for non-contact level food safety and where higher resistance against washing of surfaces is required.

Food Safe coating is suitable for internal applications for contact level food safety with anti-microbial properties.

Surface Profiles:

ISOTHERM 45/250 corrugated profile on the external side respectively and as standard Low Rib profile on the internal side.
