How to make your home warm and cost-efficient: a proper facade insulation system + a finishing cladding that protects the insulation and keeps the exterior looking great for years.
Why facade insulation is needed
Facade insulation isn’t an “extra option” — it’s one of the most effective ways to reduce heat loss in a home. A significant portion of heat escapes through the walls, so a well-designed facade immediately affects:
heating costs in winter and cooling costs in summer
comfort (walls feel “warmer,” less dampness)
protection of the walls from temperature swings and moisture
durability of both the finish and the building itself
Main facade insulation systems
1) “Wet facade” (ETICS)
A classic system most commonly used in private houses:
Wall (brick/block/concrete) → Adhesive → Insulation (EPS polystyrene or mineral wool) → Dowels → Reinforcing layer (adhesive + fiberglass mesh + corner beads) → Primer → Finish (plaster or cladding, for example KORDEKO flexible tile)
Pros: budget-friendly, lightweight system, good for renovation.
Cons: technology-sensitive — mistakes lead to cracks and delamination.
2) Ventilated facade
Insulation with an air gap and cladding on a substructure (more expensive and more complex, but performs well with moisture management).
Which insulation materials are chosen most often
EPS (expanded polystyrene)
warm, lightweight, easy to work with, affordable
important: follow fire-safety solutions and proper installation technology
Mineral (stone) wool
a “breathable” system, non-combustible, good sound insulation
requires proper moisture protection and careful installation without gaps
XPS (extruded polystyrene)
most often used on the plinth/base area where moisture and mechanical loads are higher
Why it’s important to think of the facade as a system
A common mistake: “Let’s glue insulation and then put something on top.”
In practice, insulation works only when all layers are compatible and protected — because the finishing layer:
shields the insulation from water and wind
protects from sun (UV) and mechanical damage
extends the service life of the entire system
That’s why many people choose a finish not “the cheapest,” but the most stable and reliable.
Insulation + KORDEKO (PletaFlex): a warm facade with a stone look
lightweight — doesn’t overload the insulation or walls
elastic — handles micro-movements better (lower risk of cracks)
resistant to moisture, frost, and sun
applied over the reinforced layer without a metal frame (fewer thermal bridges)
gives the look of natural stone/brick/slate/wood without heavy materials
Typical facade insulation mistakes
installing insulation over a weak base (old paint/plaster barely holding)
gaps between insulation boards (thermal bridges)
too few dowels or wrong fixing pattern
mesh placed “on the insulation,” not embedded in the reinforcing layer
no reinforcement of corners and window areas
working in rain/frost/heat without protecting the facade
Facade insulation is the most direct path to savings, comfort, and long-term protection of your home. But the best result comes not from “insulation alone,” but from a correct facade system where the finishing cladding protects the insulation and preserves the exterior appearance.
If you want a warm facade “with a stone look” without heavy structures, KORDEKO flexible tile (PletaFlex) is an excellent fit for this task.
