Soundproofing a flat in Mallorca costs €1,200-7,700 installed, depending on treated area and acoustic system. Prices per m² range from €58/m² (decoupled BA13 12.5 mm UNE-EN 520 lining + CW48 + 60 mm Rockwool) to €95/m² (CW70 double-frame with viscoelastic membrane). All values in this guide are real figures from projects delivered in 2024-2026 in Mallorca and align with our official price table. In 2025 we delivered 508 projects on the island (~254 acoustic), on top of an internal track record at Plaquistas y Acabados SL of more than 6,000 projects since 2004.
The answer depends on noise type (airborne or impact), area to treat, improvement level required (12-22 dB) and building accessibility. For legal requirements, see the CTE DB-HR regulations in the Balearic Islands; the baseline target is DB-HR §2.1 (DnT,A ≥ 50 dB between dwellings). If you live in an old flat, also review the acoustic insulation in old Palma buildings guide.

What does it cost to soundproof walls, ceilings and floors in Mallorca?
Wall soundproofing (acoustic wall linings)
An acoustic wall lining is the solution against airborne noise transmitted through the party wall: voices, TV, music. It is the most requested soundproofing intervention in Mallorca.
Basic wall lining (single board + standard mineral wool):
- CW48 framing (U-track + CW stud), 40 mm Isover Arena mineral wool (30-40 kg/m³), single BA13 12.5 mm UNE-EN 520 board (Placo Phonique or Placo Diamant).
- Acoustic improvement: 8-12 dB (ΔR'A).
- Installed price: €45-55/m².
- Suitable for: minor improvements, moderate neighbour noise.
Upgraded decoupled wall lining (double board + high-density wool):
- CW70 framing on Knauf KGT/KGN elastic bands under track, Rockwool or Isover Arena 60 mm mineral wool (60 kg/m³), double BA13 12.5 mm UNE-EN 520 board (Placo Phonique + Placo Diamant), resilient perimeter tape.
- Acoustic improvement: 12-17 dB (ΔR'A).
- Installed price: €58-72/m².
- Suitable for: most residential situations with direct neighbour noise. This is our standard spec in flats in Santa Catalina, Pere Garau or El Molinar (Palma) to hit the DnT,A ≥ 50 dB target of DB-HR §2.1.
Maximum-performance wall lining (double frame + viscoelastic):
- Independent twin CW70 framing on Knauf KGT bands, 80 mm Rockwool mineral wool (70 kg/m³), double BA13 UNE-EN 520 board with Tecsound viscoelastic membrane or Knauf Silentboard.
- Acoustic improvement: 17-22 dB (ΔR'A).
- Installed price: €78-95/m².
- Suitable for: flats above premises with music, nightclubs, extreme noise (typical in Magaluf, Santa Ponsa or Playa de Palma, where dwelling-to-premises walls also need to comply with DB-SI §3.2 fire sectorisation EI-60/EI-90).
Ceiling soundproofing (acoustic false ceilings)
An acoustic false ceiling cuts both airborne noise from the neighbour above (voices, music) and impact noise (footsteps, furniture dragging, objects dropping).
False ceiling with rigid suspension:
- F47 framing on direct hangers, 60 mm Isover Arena mineral wool, BA13 12.5 mm UNE-EN 520 board.
- Improvement: 8-12 dB airborne, 5-8 dB impact.
- Installed price: €35-45/m².
False ceiling with anti-vibration suspension (recommended):
- F47 framing on Knauf KGN elastic dampers or Sylomer silent blocks, 80 mm Rockwool/Isover Arena mineral wool (60 kg/m³), double BA13 12.5 mm UNE-EN 520 board (Placo Phonique + Placo Diamant).
- Improvement: 14-18 dB airborne, 14-20 dB impact.
- Installed price: €48-62/m².
High-performance false ceiling:
- F530 decoupled framing with premium anti-vibration suspension, 100 mm Rockwool mineral wool, double BA13 UNE-EN 520 board with Tecsound viscoelastic membrane.
- Improvement: 18-22 dB airborne, 18-24 dB impact.
- Installed price: €65-85/m².
- Suitable for: recording studios, home cinemas, extreme situations.
See the drywall false ceilings in Mallorca catalogue for complete systems.
Floor soundproofing (floating floor)
A floating floor is the most effective solution against impact noise when it is possible to work on the source flat.
Floating floor with polyethylene membrane: 5 mm cross-linked membrane + 4-5 cm self-levelling mortar. Impact improvement: 15-20 dB. Price: €25-35/m².
Floating floor with compressed mineral wool: 20-30 mm high-density panel + 5 cm self-levelling mortar. Impact improvement: 22-28 dB. Price: €35-48/m².
Multi-layer floating floor: viscoelastic membrane + resilient panel + self-levelling mortar. Impact improvement: 28-35 dB. Price: €45-60/m².
Prices exclude final finish (timber, tiles).
Factors That Affect the Price in Mallorca
Island logistics
Materials (BA13 UNE-EN 520 Placo/Knauf boards, CW48/CW70/F47/F530 profiles, Isover Arena and Rockwool wool) are manufactured on the mainland and arrive through the port of Palma. Sea freight, port handling and local distribution add 10-20% over mainland prices (internal data from Plaquistas y Acabados SL across 254 acoustic projects/year).
Total area to treat
From 40-50 m² of treated area, fixed costs (travel, preparation, sealing) are amortised and the per-m² price drops to the lower end of the range. Under 15-20 m², the per-m² price rises 15-25% due to the fixed-cost share.
Building accessibility
In buildings without lift, with narrow staircases or in pedestrian streets of Palma's Historic Centre, material haulage adds 8-15% to the quote. Boards are 2.60 m long and must be carried by hand when there is no lift.
Required finish level
The base price delivers the installation with treated joints and primer ready to paint. Relocating electrical fittings, integrating recessed lighting, adding inspection hatches or matching existing mouldings add 10-20%.
Time of year
Demand peaks between February-May and September-November: timescales stretch and prices rise 5-10%. June-August and January have lowest demand and offer better terms.

Pattern replicated on flats in Inca, Manacor, Pere Garau, El Molinar and Cala Major.
Comparison: Drywall vs Other Soundproofing Solutions
Adhesive acoustic panels
Foam, polyester or mineral-wool panels glued directly to the wall. Cost: €8-15/m². Improvement: 2-5 dB. They reduce reverberation within the room but do not block neighbour noise. Not a real soundproofing solution.
Cavity-injected insulation
Polyurethane foam, cellulose or blown wool injected into the cavity. Cost: €20-35/m². Improvement: 4-8 dB. Only viable if the cavity is real and continuous, and does not decouple the structure, so performance is limited.
Decoupled drywall wall lining
Recommended system. Cost: €58-85/m² installed. Improvement: 12-17 dB. Best cost-performance-practicality ratio. Reference build-up: BA13 12.5 mm UNE-EN 520 + Rockwool 48-60 mm + Knauf KGT/KGN resilient band + perimeter tape. Installable on any wall regardless of composition.
Double brick partition
Second brick leaf with cavity. Cost: €55-75/m². Improvement: 10-15 dB. Weighs 100-150 kg/m² against 25-40 kg/m² for drywall, requires drying times and performs worse if leaves are not decoupled. On old slabs, extra weight can become a structural issue.
Full "acoustic box" system
For extreme situations (flat above a nightclub, recording studio): decoupled lining on every wall + anti-vibration false ceiling + floating floor. Cost for a 15 m² room: €6,000-10,000. Improvement: 25-35 dB.
How to Cut the Cost Without Losing Effectiveness
Prioritise the surfaces that transmit the most noise
Spending €1,500 on the right wall is more effective than spending €5,000 across the whole home without a technical criterion. Identify the main source (party wall, upper slab, blind boxes) and tackle it first.
Choose the right system for each surface
The party wall with a noisy neighbour may need a decoupled lining (€58/m²). The wall facing the communal corridor can be solved with a basic lining (€45/m²). Matching the system to each surface optimises the investment by 20-30%.
Group the works
Soundproofing several rooms in one go reduces fixed costs and cuts the per-m² price by 8-15% from 30-40 m².
Avoid demand peaks
February-May and September-November are Mallorca's peaks. Scheduling for June-August or January lets you negotiate better terms.
Get several itemised quotes
Not to pick the cheapest blindly, but to understand what system and material each one includes. The difference is usually in wool density (60 kg/m³ vs 30 kg/m³), the presence of anti-vibration bands and perimeter acoustic sealing.
What Soundproofing Quotes Do Not Include
- Final decorative paint: €4-8/m² separate. Drywall is delivered with primer ready to paint.
- New electrical works: new sockets, switches or light points are quoted separately.
- Plumbing: adapting walls with pipes is additional.
- Licences and permits: in most Mallorca municipalities, wall linings and false ceilings are minor works without a licence, although some require a prior notice (€50-100 fee). On dwelling-to-premises walls subject to fire sectorisation under DB-SI §3.2 (EI-30 to EI-120 depending on use), the system spec may have to be justified.
- VAT: the 10% reduced rate applies to renovations in homes older than 2 years; the 21% general rate applies to new-build or commercial premises. The thermal envelope (Mallorca, climate zone B3 under DB-HE §3) can qualify for grants when treated together.
