Continuous Sandwich Panel-Redefining Construction
Satmax sandwich panels are typically single piece, factory made units which consist of an insulating layer of rigid Polyurethane Foam or Rockwool between two layers of mark sheets.These panels have unique tonque and grove joinery for air and water tight, effective panel to panel interlocking make it easier and quicker to install and providing an effective seal. All joints are covered with flashings and sealants. steel structure framing are provided where every necessary as per user customised design.
Why Insulated Sandwich Panel ?
- High Thermal Insulation
- Usable as structure panel for wall & roof.
- Closed Cellular Structure-inherently water resistant.
- Available in any lengths depending upon logistic convenience.
- External and internal steel facing best effective vapour barrier.
- All weather proof and sustainable.
- Self extinguishing-avoid spread of flames in case of fire.
- Resistance to Corrosion, termite and fungus.
- CFC free and zero ozone depletion property.

Basic Properties Of Insulation Cores
|PUR||Rigid Polyurethane Foam||Most popular, widely used, ideal insulator. It is thermosetting material when exposed to fire, does not drip or melt; forms a strong carbonaceous char that protects the core and prevents spread of flame. Additions of FR agents further augment fire retardant properties. It is CFC free & self extinguishing. Conforms to IS-12436-88.|
|PIR||Polyisocyanurate Foam||Offers higher fire rating and is non-ignitable. Better closed cell structure offered by trimerisation process offers better thermal performance. It is CFC Free, longer lasting, hygienic and food safe. Ideal for Cold Rooms.|
|ROCKWOOL||Rockwool||Naturally occurring fibre with very high temperature resistance properties. It is fireproof, emits no smoke or gases, is water repellant & Non-capillary. The process re-orientation of vertical fibre structure imparts high Shear, Compressive and Tensile strength, thus making the Panels strong and stable. Rock wool with excellent acoustic properties is chemically neutral, vermin proof, re-cyclable and bio degradable. Ideal for Partitions, Internal walls, Acoustic Insulation, and FR & HT applications for Power Plants etc. Conforms to IS-8183.|
