A client has a possibility to choose from five walls, which meet the requirements for low-energy and passive houses. We have all our houses evaluated by Archenergy company – an authorised specialist for an energetic evaluation of the houses. We evaluate not only coefficient of heat penetration, but also amount of condensed steam in constructions – all our constructions are convenient, of course. Our standard wall LUCERN eko - concerning diffusively closed construction used with standard houses of our company. It has an excellent coefficient of heat penetration and it falls into low-energy living. LUCERN eko plus wall comes out form the standard wall LUCERN eko and is added in addition with mineral isolation in installing space, due to which it reaches better heat-isolating figures. The third wall LUCERN difuz is based on a fine wood fibre plate and with its composition belongs to diffusively open constructions. LUCERN difuz wall plus has against to LUCERN difuz wall twice thicker wood fibre plate, so it meets requirements for a passive house. The last but not least LUCERN pasiv wall creates first-rate materials and with its coefficient of heat penetration
U= W/m2K belongs to the finest constructions on the Czech market.
The fundamental wall of our firm, which meets high demands for cost-saving living. The coefficient of heat penetration meets all of the standards and with its value categorises itself into low-energy almost passive wall. The facade system create graphite plates with heightened isolating impact (used for low-energy and passive houses). In view of the fact that a diffusively closed construction is being considered, we use for strengthening KVH prisms of OSM plate P+D. The KVH prisms are filled with mineral isolation and strengthened with KVH laths, which hold PE vapour barrier. A valve from the side of interior is made by fine construction plate rigistabil. Space between rigistabil and vapour barrier is used as installation room for distribution of cables and pipes.
LUCERN eko plus
The fundamental wall of our company – LUCERN eko was improved with the mineral isolation in the installation room, so it became a name LUCERN eko plus and mainly it belongs to passive walls due to its coefficient of heat penetration.
The first-rate diffusively open wall, which is created by a wood fibre plate, which also serves as stabilisation feature of bearing construction KVH. The KVH prisms are strengthened for a better statics and a possibility of insertion of thicker mineral isolation. The construction is closed with vapour barrier from the side of interior and strengthened by KVH laths. The installation room for distribution of cables and pipes is filled with a mineral isolation. The coefficient of heat penetration meets low-energy wall standard.
LUCERN difuz plus
The LUCERN difuz wall was twice as big strengthened of wood fibre plate and became a name LUCERN difuz plus. Due to coefficient of heat penetration falls this construction into passive standard.
Our most finest construction, which meets the most strict requirements for passive living. The diffusively closed construction is being considered, which is created by strengthened KVH prisms filled with mineral isolation and closed by the interior side for static strengthening with fermacell. The facade system is created by mineral isolation (difuz open system). From the interior view is the KVH construction strengthened with laths and provided with vapour barrier. The installation space for distribution of cables and pipes is filled with mineral wool and closed with a very fine rigistabil construction plate. The coefficient of heat penetration comes out to unbelievable 0,11 W/m2K, and so it integrates itself into the finest constructions on the Czech market.
