WOOD FLOOR TYPES
COMPARISON WOOD FLOOR TYPES SOLID VS. ENGINEERED WOOD FLOORS Made out of one single piece of wood Sensitive to moisture (width) Long life-time (renovation, re-sanding) Many different types: Planks / strips Lam Mosaic Industrial Wood paving 2 Made out of several wood layers Bonded together (90⁰) Dimensionally more stable (width) Less affected by moisture Two different types: 2 ply engineered 3 ply engineered or more
PLANKS & STRIPS SOLID WOOD FLOORS Distinction in size With tongue and groove Sensitive to moisture changes (width) Planks: meters Stirps: centimeters Full surface bonding Nailing Can be sanded several times Suitable for underfloor heating Built to last 3
LAM PARQUET SOLID WOOD FLOORS Economical (cheap) Without tongue and groove Sensitive to moisture changes (width) Size: 10 x 50 x 250 mm Full surface bonding Two laying patterns: parallel, herringbone Can be sanded several times Easy replacement of individual pieces Suitable for underfloor heating 4
MOSAIC PARQUET SOLID WOOD FLOORS Mostly 7 wood pieces form a unit Two laying patterns: parallel, checkered Not very sensitive to moisture changes (checkered) Piece: 8 x 23 x 160 Mats: 320 x 640 Full surface bonding only Finished on construction site Can be sanded several times Suitable for underfloor heating 5
MOSAIC PARQUET SOLID WOOD FLOORS Mostly 7 wood pieces form a unit Two laying patterns: parallel, checkered Not very sensitive to moisture changes (checkered) Piece: 8 x 23 x 160 Mats: 320 x 640 Full surface bonding only Finished on construction site Can be sanded several times Suitable for underfloor heating 6
INDUSTRIAL PARQUET SOLID WOOD FLOORS Scrap from mosaic parquet Wood pieces are turned edgewise Not sensitive to moisture changes Full surface bonding only Finished on construction site Can be sanded many times (thickness) Suitable for underfloor heating 7
INDUSTRIAL PARQUET SOLID WOOD FLOORS Scrap from mosaic parquet Wood pieces are turned edgewise Not sensitive to moisture changes Full surface bonding only Finished on construction site Can be sanded many times (thickness) Suitable for underfloor heating 8
WOOD PAVING SOLID WOOD FLOORS Wood fiber perpendicular to floor Very hard surface Strong swelling and shrinking (T or R) Full surface elastic bonding only Requires higher substrate strength Higher amount of adhesive necessary Finished on construction site Can be sanded many times (thickness) 9

ENGINEERED WOOD FLOORS Made out of one single piece of wood Sensitive to moisture (width) Long life-time (renovation, re-sanding) Many different types: Planks / strips Lam Mosaic Industrial Wood paving 11 Made out of several wood layers Bonded together (90⁰) Dimensionally more stable (width) Less affected by moisture Two different types: 2 ply engineered 3 ply engineered or more
2-PLY ENGINEERED ENGINEERED WOOD FLOORS Consisting of 2 layers (90⁰) Cuts at the bottom side (2 nd layer) compensate stress differences Very small tongue and groove (nailing) Full surface bonding Substrate acts as 3 rd layer for stabilization Can be sanded Suitable for underfloor heating 12
3-PLY ENGINEERED ENGINEERED WOOD FLOORS Consisting of 3 layers (different wood types) 1 st and 3 rd in same direction, always 90⁰ Higher stability than 2-ply Bigger tongue and groove (nailing) Floating installation Full surface bonding Nailing Can be sanded Suitable for underfloor heating 13
LAMINATES ENGINEERED FLOORS Melamine wear layer (top) (1) Print film (wood imitation) (2) Antistatic paper (3) Core (HDF panel, isotropic) (4) Backing (stability) (5) Maybe footfall sound insulation (6) Floating installation (PE / PVC sheet) Interlocking (click systems) Conventional tongue and groove (bonded) Bonding only after verification of adhesion properties of backing 14
TONGUE & GROOVE VS. INTERLOCKING SYSTEM TWO WAYS OF SPLICING 15
WOOD FLOORS GOOD TO KNOW Parquets: defined as small(er) wood pieces (mosaic, industrial, lam) economical (cheap) easy replacement of individual pieces Job site finished: Mainly mosaic, industrial and Lam parquet (solid wood floors) Boards are sanded and finished after installation Unevenness is eliminated with sanding: a noisy and dusty procedure Floor cannot be walked on while finishing is curing Factory finished: Mainly 2- and 3-ply, laminate (engineered wood floors) Boards are sanded and finished in the factory Unevenness can be spotted very easily No sanding required at job site: clean procedure V-Joints can equalize unevenness 16
