Façades · finish Render (crepi)
A flat, coherent surface — as a stand-alone skin or as a connecting layer between wood, stone and aluminium. On an insulated façade it is the finish of a complete ETICS system.

- Vapour-openthe wall can breathe
What is crepi render? A plaster with a grain.
Crepi is a façade render with a grainy texture. We work with silicone render: a ready-made premium system for a flat, modern façade.
It is elastic, water-repellent and vapour-open — the wall stays dry and can breathe.
- Ready-made premium system
- As a stand-alone finish or on insulation
- Any colour from the swatch book
Render (crepi) · Silicone renderWhich grain? The grain determines how the façade catches the light.
Modern render gives architecture a flat, coherent surface — as a stand-alone skin or as a connecting layer for wood, stone and aluminium.
Grain 1.0 mm — almost smooth
The finest structure: it looks almost like paint with a slightly rough feel. This result needs more careful preparation, an extra levelling layer and therefore a higher project cost.
- Almost smooth
- Extra levelling coat
- Careful preparation
Grain 1.5 mm — standard
The standard grain for a balanced, clearly legible façade structure. A trusted choice that balances texture and ease of maintenance.
- Standard texture
- Balanced relief
- A versatile choice
Grain 2.0 mm — coarser
A coarser grain for a more pronounced, robust relief. Interesting when the façade may have a stronger tactile presence.
- Coarser relief
- Pronounced texture
- Robust character
Render on façade insulation (ETICS) Five layers, one certified system.
On an insulated façade, render is the outer layer of one system from one manufacturer — so the warranty covers the whole.
- 01Substrate
Existing wall, checked for flatness and moisture
- 02Adhesive
Full-surface bonding, plus anchors where needed
- 03Insulation
EPS, graphite EPS or mineral wool — thickness according to your energy goal
- 04Reinforcing mesh
Glass fibre mesh in a reinforcement layer against cracking
- 05Render (crepi)
Silicone render in the chosen grain and colour
Preparation and details A rendered façade is only as good as its substrate.
What we check and carry out before the last layer goes on:
- ✓
Checking the substrate and moisture before work starts.
- ✓
Continuous details around windows and doors, so no thermal bridge is created.
- ✓
A plinth that resists moisture and dirt: waterproof layer, XPS or EPS HD and reinforcement.
- ✓
Dark colours only with a system that can handle high surface temperatures, such as Caparol Carbon Dark or Knauf Color-X.
Projects Rendered façades we created.
From a terraced house in Mechelen to 540 m² of brick slips and white render in Hasselt.

Combining render A calm background for accents.
Render lets wood, stone, aluminium or ceramics speak. In Neerpelt we combined render with wood and brick slips, in Hasselt 540 m² of brick slips with white render on 12 cm of insulation. Spray cork and render also go together on one façade.
Grants and financing
We check what you are entitled to.
Since 2026, wall insulation in Flanders only qualifies for Mijn VerbouwPremie in income categories 3 and 4. We check your situation, help with the application and, if you wish, arrange a renovation loan through KBC.
Questions about render What our clients ask us.
Which render grain should I choose?
A 1.5 mm grain is the standard: a balanced texture that balances texture and ease of maintenance. 1.0 mm looks almost smooth but needs an extra levelling layer; 2.0 mm gives a coarser, more robust relief.
Can render be used without façade insulation?
Yes, render can be a stand-alone finish. We always check the substrate and moisture first. If you are tackling the façade anyway, render is usually combined with insulation in an ETICS system.
Can I choose a dark rendered façade?
Yes, with a system that can handle high surface temperatures, such as Caparol Carbon Dark or Knauf Color-X with Total Solar Reflection.
Can I get a grant for façade insulation?
In Flanders, since 2026 wall insulation only qualifies for the Mijn VerbouwPremie grant in income categories 3 and 4. We review your situation and help with the application.
