Owner of data set Mannok |
Technical purpose This LCA is carried out for Mannok EPS Pearl 70. Only the 100 mm thicknesses are listed on this EPD. Mannok can send the EPD’s of other alternative thicknesses upon request. Process description is the same for all varieties. The number indicates the compressive strenght of the material in KPa.
The constituent raw materials of the Mannok EPS are simple and consist of a single material: EPS Expandable PolyStyrene. These materials are used in the full range of products. Multiple suppliers deliver raw materials (EPS Beads) to Mannok and each (Non-Expanded) Polystyrene material has slightly different characteristics, also in the compressive strenght characteristics. The only additional material that all products have is wrapping foil in the packaging process. The wrapping foil is in-scope and modeled.
Mannok EPS is used in the insulating of cavity walls, floors and roof insulation of commercial, industrial and domestic buildings, as well as in a wider range of applications such as the lightweight fill for roads and as packaging material. The “Pearl” product type also consists out of EPS but use, in the wordings of Mannok, more advanced EPS polymers, that offer improved thermal performance.
The service life of the product is taken as 50 years.
The Lite Pac EPS Pearl have a higher thermal resistance than the Lite Pac EPS beads – being 1,16 times higher
R-value for the same thickness and density of finished product. The insulation boards are used in the following
applications:• Insulation for floors, roofs and walls for domestic and commercial builds
• Void formers for bridge decks• Flotation units for marinas• Packaging• Lightweight fill for road construction
The higher density boards are used in underfloor and foundation applications:
• Domestic floors - EPS 70 / EPS Pearl 70 Mannok EPS and Mannok EPS Pearl are manufactured by using steam to expand polystyrene beads to approximately forty times their original size. As the beads expand they bond and can then be moulded to the required shape. The sole ingredient of the moulded insulation is polystyrene beads, that contain a small amount (approx. 5 % by weight) of pentane gas. The expanded insulation is manufactured to EN 13163:2012+A1:2015, Thermal Insulation Products for Buildings - Factory Made Expanded Polystyrene (EPS) Products - Specification. |
