Drywall – Projects and Qualified Teams

Drywall construction is the fastest and most flexible way to structure interior spaces – no wet work, no long drying times. The trade covers gypsum board and gypsum fibre walls, suspended ceilings, wall facings, floor build-ups, and specialised structures for sound insulation, fire protection, and damp areas. Quality depends on correctly selecting board thickness and stud direction, proper finishing in the required Q-level (Q1 to Q4), and clean junctions with adjacent building elements. Example Germany: sound insulation is governed by DIN 4109, fire protection classification follows DIN EN 13501-1 (European standard).

FAQ

How much does drywall cost per m² as subcontracted work?

How thick must a drywall partition be?

Which finishing level fits which application?

What are the acoustic requirements?

What are the most common defects on site?

How long does a 100 m² wall area take to install?

How much does drywall cost per m² as subcontracted work?: Example Germany: standard partition wall 35–55 €/m² (incl. material), acoustic wall 50–80 €/m², suspended ceiling 40–70 €/m². Surcharges for Q3/Q4 finishing, fire-rated walls, or curved structures. In Poland prices are typically 30–40 % below German rates.
How thick must a drywall partition be?: Standard partition with single CW stud and double-sided sheeting: 100–125 mm. With enhanced acoustics or double sheeting: 150–250 mm. F90 fire-rated walls: usually 125–150 mm with specialised gypsum boards.
Which finishing level fits which application?: Q1: joint filling only, acceptable behind tiling. Q2: standard for wallpapered walls. Q3: for matt paints and textured wallpaper. Q4: full-surface smoothing, mandatory under raking light or gloss coatings.
What are the acoustic requirements?: Example Germany: DIN 4109 distinguishes minimum and enhanced sound insulation. Apartment-separating walls: ≥ 53 dB. Double-stud walls with insulation reach over 65 dB. The European DIN EN ISO 717-1 applies as the rating procedure.
What are the most common defects on site?: Cracking at junctions due to missing separation strips, poor acoustics from sound bridges across continuous studs, visible edges at Q4 from incorrect lighting, missing backing behind sockets in fire-rated walls.
How long does a 100 m² wall area take to install?: Standard partitions: 2–3 days for an experienced two-person team including Q2 finishing. With acoustic or fire protection: 3–5 days. Depending on junction situations, service cut-outs, and door openings.
