Perimeter insulation is the corollary to the facade insulation due to the rapid increase in heating costs and builders are the impending climate change or real estate operators seek effective measures to reduce heating costs and related emissions significantly. In addition to a series of measures, thermal insulation system made of EPS (expanded polystyrene) are the first choice. For new and old buildings, thermal insulation but not in the base area should be regarded as completed. The significant reduction of cold radiation, but also to prevent humidity and often associated mold damage in the very critical transition range of insulated uninsulated areas the perimeter insulation is the logical continuation of the wall insulation. nions on the subject. In addition to lowest thermal conductivity, efficiency and long-term stability are indispensable for the insulation of Earth touched components. The advanced properties of the W-PER DRV system IsoBouw is a Kombidammsytem with protection and drainage function.

The a surface drainage without the additional use of drain mats, saving a single operation can allow form foamed EPS insulation boards. Through the integrated Stud pattern, water falling on derives from reliable ring drainage. So the drainage structure works in the long term a geo filter fleece laminated on. The panels have a precisely executed around ongoing Shiplap to avoid thermal bridges. Lothar Traub the IsoBouw W PER DRV-system is highly resistant to pressure (150 kPa or 250 kPa) and thus up to a depth of 6 m. The low thermal conductivity by 0.035 W / M.k. promises the best possible insulation properties.

The W-PER DRV is produced in thicknesses from 50-200 mm to meet all applications required in practice. In addition to the properties described, all IsoBouw perimeter insulating boards protect the delicate waterproofing for the backfilling of the excavation from damage. The gluing of panels is carried out with a solvent-free Bituminous cold adhesive. The technical characteristics are permanent even under extreme loads in the ground. The polystyrene foam used for manufacturing produced CFC-free, is 100 percent recyclable and construction biologically harmless. So IsoBouw a significant contribution to environmental protection.
