Thermal insulation
made of LIGNO®
Supports for energy-efficient building shells
The lower the U-value of a component and the lower the psi value of the details, the less heat is lost. This is precisely where the U*psi cross-laminated timber insulating uprights from Lignotrend come into effect: They implement high insulating thicknesses in natural timber and minimise thermal bridges.
As a highly thermally insulated curtain wall
The ladder rung structure of U*psi reduces the heat transfer to a minimum.In the U*psi F facing version, the ladder element is used as a spacer on façade or exterior wall constructions made of timber, masonry and concrete.
In the form of the U*psi S adjusting upright, it compensates for uneven or sloping surfaces – for example in renovation work or in sensitive façade designs.
For new buildings and energy-efficient renovation
The U*psi insulating upright spans the insulation level with minimised thermal bridges in new buildings as well as in energy-efficient renovations – no matter what building material the supporting exterior wall is made from. On or underneath floors adjoining unheated rooms, the ladder element can be used to elevate the floor or to suspend false ceilings.
In the roof construction
U*psi ladder elements can also be doubled up as non-load-bearing counter rafters on an already existing load-bearing roof construction, e.g. made of cross-laminated timber panels or traditional rafters – both in rear-ventilated pitched roofs and in flat roofs. Separate rafters are then arranged for larger roof overhangs.
Highly efficient exterior wall insulation
Configuration options – insulating uprights
The fastening of U*psi is very economical – it is done simply at the rear spar using short fasteners. An installation layout transverse to the uprights is possible and is interesting above all for the renovation of masonry, for example.
The U*psi insulating upright transfers the façade loads to the load-bearing structure in a ladder-like manner. The insulation layer is accommodated in-between. Thermal-bridge-minimised details enable KfW insulation standards to be met as well as other energy standards from the low-energy house to passive house or Minergie-P.
U*psi is manufactured from natural timber. Insulated with injected insulating flakes such as cellulose and wood fibre, the system is an ecological alternative, for example, to rigid foam panels. Alternatively, insulating materials in the form of mats can be used (e.g. non-combustible mineral wool).
As a rule, wood fibre insulating boards close off the insulation chamber. Different façade designs are possible: plastered, as a ventilated timber façade or with other façade cladding.
Product properties – façade insulating upright
Surface design
U*psi is manufactured according to the cross laminated timber principle by crosswise gluing of board layers. It is therefore particularly dimensionally stable and precisely straight and is therefore also suitable as a quiet substructure for the safe execution of all types of façades, especially rendered façades.

Plaster - wood - etc.
Thermal insulation
In front of load-bearing components made of wood, masonry or concrete, type F is used as a "spacer" to bridge the insulation level between the load-bearing structure and the façade cladding with as little thermal bridging as possible.

Ecological material
Lignotrend's sensitivity to the sustainable use of natural resources has led to the development of its own product, which can be used to produce large insulation thicknesses from renewable raw materials.

Assembly
The insulation joist are fixed to the rear chord with short fasteners. An installation guide across the uprights is easy to implement.
