Wood Flooring Grades: How They Define the Final Look
Choosing the ideal wood floor begins with understanding the different grades available. Each grade features unique visual and technical characteristics, helping you match the appearance and performance to your project requirements. EDVA Group provides a variety of premium flooring grades, tailored to specific architectural concepts and durability needs. Explore our grading guide below to find the ideal match for your project.
Grade Comfort– Prime Wood Flooring for a Clean, Uniform Look
Comfort grade wood flooring, also known as Select or Prime, is the top tier of parquet options. It is prized for its very uniform appearance, with minimal color variation between planks and almost no visible knots. This creates a clean, contemporary, and sophisticated look, ideal for modern interiors and projects where a consistent visual flow is required.
Color variation: Slight difference
Knots: Healthy knot up to 8 mm
Cracks: Not allowed
Wormholes: Not allowed
Processing defects: Not allowed
Grade Classic– Balanced Wood Flooring with Natural Character
Classic grade wood flooring offers a balanced combination of elegant appearance and a touch of natural character. Compared to Comfort grade, Classic includes a few small knots and slight surface repairs, carefully matched to the wood tone. The result is a subtly varied oak parquet floor that highlights the natural beauty of wood while still looking refined and timeless.
Color variation: Moderate difference
Knots: Healthy up to 30 mm, falling out filled knots up to 10 mm
Cracks: Allowed (filled)
Wormholes: Not allowed
Processing defects: Not allowed
Grade Rustic– Characterful Parquet with Strong Natural Variation
Rustic grade wood flooring is one of the most popular choices. This grade celebrates the full character of real wood: larger knots, filled cracks, shakes, visible sapwood, and strong color variation between planks. Rustic oak parquet is ideal for interiors where a natural, expressive, and authentic wood floor is a key design feature.
Color variation: Unlimited
Knots: Healthy up to 60 mm, falling out filled up to 40 mm
Cracks: Allowed (filled)
Wormholes: Not allowed
Processing defects: Not allowed
Distinctive Features of EDVA Group Parquet Boards
High-Precision Geometry
High-precision plank geometry ensures a perfectly even surface and tight joints between boards, improving both the aesthetic appeal and the durability of the floor.
Real European Quality
We ensure full compliance with strict environmental standards and regulations. EDVA Group parquet boards are manufactured in Europe and meet modern safety and sustainability requirements.
Thermally Modified Wood
Thermal modification improves the stability and performance of the wood by reducing its natural moisture content to 4–6%. This helps minimize warping, cupping, and movement during seasonal climate changes.
Three-Layer Construction
A three-layer engineered construction effectively compensates for natural wood movement. The cross-laid layers help the parquet board remain dimensionally stable under temperature and humidity fluctuations.
Tongue & Groove System (T&G)
The traditional tongue & groove profile allows the parquet boards to slot neatly into place, providing a secure fit and a smooth, continuous surface.
2G Click-Lock System
The 2G Click-Lock system enables quick, clean, and precise installation without the need for adhesives or nails, making it ideal for projects with tight timelines.
UV Oil Finishes
At EDVA, we focus on hardwood floors that highlight the natural beauty of wood. Our UV oil finishes provide enhanced durability while preserving a warm, natural appearance and protecting the surface from daily wear.
The Main Advantage of Parquet Boards
The key advantage of engineered parquet is its stability and flexibility of installation. In many projects, it can be installed as a “floating” floor: the boards are not fixed to the subfloor but are connected to each other using the locking system, which simplifies installation and reduces project time.
