What is the insulation material called? 2 flexible elastomeric foam 3 sheet metal 1 mineral wool Label and describe the pictures. Work in pairs and define these parts. Which materials are they made of?  sheet metal  What are they used for? bend segment & 90° bend vessel cone used to insulate pipes/pipe work used for heating systems used for changing diameters of pipes An insulation specialist gives a presentation concerning insulation work and insulation materials. Discuss the statements and decide which of them are true or false. true false 1. Insulation materials are good heat conductors. poor heat conductors 2. The metal cladding is made of 0.6 mm thick copper sheet. aluminium 3. Mineral wool consists of inorganic strands of mineral fibre bonded together using organic binders. 4. The connection between the bend segments is done by longitudinal seams and secured by screws. 5. A reduction of heat loss leads to a reduction in carbon dioxide emissions. 4. is done by swages Discuss this sentence with a partner: “Insulation offers a contribution to environmental protection”. Is it true? Why? Insulation reduces carbon dioxide emissions, which in turn are responsible for global warming. It is a poor heat conductor and therefore causes reduced heat loss. Can you name other insulation material apart from those mentioned above? Search the internet and find some other suitable materials for heat and cold insulation. rock and slag wool (Steinu. Schlackenwolle), polyurethane rigid panels (Polyurethan Hartplatten), expanded polystyrene (expandiertes Polystyrol), expanded perlite (expandierte Perlite) 07 A2–B1 listening ck6n2t 08 A2–B1 09 A2–B1 ✗ ✗ ✗ ✗ ✗ 10 A2–B1 11 B1 126 Unit 29 Interaction Nur zu Prüfzwecken – Eigentum des Verlags öbv
