Why people choose us in Benidorm

Joinery specialists for high-rises and holiday apartments

Benidorm has more skyscrapers per capita than any other city in the world (348 buildings over 35 m according to CTBUH). A 25th-floor apartment in Edificio Gemelos or Intempo (192 m) has problems that simply do not exist in a street-level home: brutal wind pressure, vibration, strict glazing safety rules. For holiday lets there is a second client: rapid turnover plus 60% British, Scandinavian, Dutch and Belgian owners. For both profiles we use specific materials and processes.

🏙️

Real high-rise experience

We have installed in Edificio Gemelos 22/24/26/28, Torre Lúgano, Coblanca, Aqua Nature and similar. We know Benidorm Council façade permits, time-window restrictions and the external cranes required from floor 15 upwards.

💨

Window engineered for your floor

On floor 25+ the dynamic wind pressure can be 2.2 times that at ground level. We design every window with wind class C5 (≥2,000 Pa) and tempered glass mandatory above floor 7 per Spanish Building Code (CTE) DB-SUA1.

🌍

Service in 5 languages

60% of Benidorm homes belong to foreign owners (Benidorm Council 2024). We work in Spanish, English, Norwegian, Dutch and German — no misunderstandings on measurements, materials or warranty.

🏨

Holiday let stays live

We work room-by-room so the apartment stays rented: we remove, manufacture to measure on a fixed timeline and install in 1-2 days per home. Ideal for owners of registered holiday-let (VUT) properties.

📑

Permits and community handled

We file the works declaration with Benidorm Council, get the community's sign-off (Gemelos 28 has 320 neighbours), book the external crane and the loading-bay permit on avenues like Mediterráneo and Europa.

🛡️

10-year written warranty

10 years on PVC and aluminium profile, 5 years on Roto NX or Maco MultiMatic hardware, 2 years on sealing and glazing. Contract signed in Spanish and English — still valid if you sell the home to the next owner.

Microclimate + extreme altitude

Why a 25th-floor flat in Benidorm needs a special window

Benidorm has a unique microclimate: 300 sunny days a year because the Puig Campana mountain range (1,410 m) blocks cold northerly winds, 67% average humidity and torrential downpours ("gota fría") in September-October. But the real issue is not the ground-level climate; it is what happens at altitude:

→Wind multiplies with altitude: Eurocode 1 (UNE-EN 1991-1-4) zone Bz1 (C). At ground level, base pressure qb = 0.5 kN/m². On floor 25 (≈75 m), the pressure on the window can reach 1,800-2,200 Pa. A standard class C3 window (≤1,200 Pa) deforms and lets water in.
→Tempered glass mandatory above floor 7 (CTE DB-SUA 1, §1.4). In Intempo (47 floors), Gran Bali (52), Gemelos 28 (43) — any breakage risks falling onto a public street. We use 6+6.4 tempered minimum, and on east-facing flats we recommend 8+8.4 tempered-laminated.
→Constant salt + UV: 300 sunny days degrade Chinese PVC in 5-7 years (yellowing, brittleness). We work only with Kömmerling class S (German UV resistance) or Salamander BluEvolution. On aluminium, QUALIMARINE coating is mandatory facing the sea.
→Oblique rain + gust = leak: the gota fría dumps 50-80 mm/h sideways. Every window is fitted with double EPDM gaskets, perimeter drainage and minimum water-tightness class 9A (E1200) — class E1500 on SE-E orientations for coastal buildings.

Benidorm data + wind calculation (AEMET / Eurocode)

Sunny days per year: 300
Average summer temperature: 26-32 °C
Average winter temperature: 12-18 °C (microclimate)
Average relative humidity: 67%
Gota fría rainfall: 50-80 mm/h (Sep-Oct)
Eurocode wind zone: Bz1 — category C
Ground-level wind pressure: ≈600 Pa
Floor-15 wind pressure: ≈1,300 Pa
Floor-25+ wind pressure: 1,800-2,200 Pa
CTE climate zone: B3 (warm-warm)

Above floor 15 we require windows with wind class ≥C5 (2,000 Pa), water-tightness ≥E1200 (9A) and tempered glass for openings >1.2 m² (CTE DB-SUA 1).

Code compliance at altitude

Regulations, wind calculation and official certificates

In Benidorm code compliance is especially demanding because of building heights. Every window leaves the workshop with CE marking, a wind-pressure calculation per Eurocode 1 and the documentation required by the Spanish Building Code (CTE).

Eurocode 1 — UNE-EN 1991-1-4

Wind-load calculation. Benidorm = zone Bz1, terrain category C (open coastline). Above floor 15 we require wind class C5 minimum (2,000 Pa nominal pressure).

CTE DB-SUA 1 §1.4 — glazing at altitude

Above 7 m from ground level, glass must be tempered or laminated safety to prevent falling outside. We use 6 mm tempered minimum + PVB film on the inner face.

CE marking (EU 305/2011)

Declaration of performance (DoP) by model and project, with specific wind (class Cx) and water (class Ex) performance. Without this, no window has been legal in Spain since 2014.

CTE DB-HE 2019 zone B3

We meet Uw ≤ 2.2 W/m²K (required) and most reach 1.0-1.2 W/m²K (class A+). Critical for the before/after energy certificate for the NextGen grant.

RC2 / RC3 anti-burglary (recommended)

Holiday let on ground floor or penthouse with accessible terrace: Roto NT hardware with anti-leverage bolts + P5A laminated glass. 3-5 min resistance to professional tools.

The team that comes to your home

Real people with names and on-the-ground experience

VentanaCosta does not subcontract: the surveyor who measures is on our payroll, and so is the installer. This matters in Benidorm because every high-rise has its own internal rules — Edificio Gemelos requires crane bookings 15 days ahead, Intempo has time restrictions, Aqua Nature asks for common-area protection.

We have been installing in Alicante and Marina Baixa since 2010. 14 years, 3,200+ homes, zero lawsuits.

FAQ

Answers to the most common questions in Benidorm

I live on floor 25 of Edificio Gemelos — which window do I need?+

At that altitude wind pressure can reach 2,000 Pa (class C5 per Eurocode 1, zone Bz1 category C). You need: Kömmerling 76 AD with 2.0 mm steel reinforcement, 6+6.4 tempered-laminated glazing (mandatory per CTE DB-SUA 1 above floor 7), RC2 hardware minimum and water-tightness class E1200 (9A). Surcharge vs standard window: 15-20%.

Do you need an external crane to hoist the windows?+

Above floor 15 almost always yes, unless windows fit in the lift (rare above 1.5 m tall). We coordinate the crane booking with the community (15-30 days lead time in Gemelos, Coblanca, Intempo) and the loading-bay permit with Benidorm Council. Crane cost is included in the quote — never a final "extra".

My apartment is rented on Airbnb — can it be installed without halting the let?+

Yes. We coordinate with your check-out and the next check-in: in standard holiday apartments (5-7 windows) installation takes 1-2 days. Usually we go in Monday after a Sunday check-out and hand over Wednesday before check-in. Zero days off-rent.

I do not live in Spain (British / Norwegian / Dutch): how does it work?+

It is our daily reality — 60% of Benidorm owners are foreign. We serve you in English, German, Norwegian or Dutch (spoken and written). On-site survey with a trusted person you have in Benidorm (administrator, neighbour, concierge). Bilingual Spanish-English contract. Payment by international transfer or card. We send you photos and video of the job so you can follow it remotely.

Do you work with large communities (200-500 homes)?+

It is our strongest profile in Benidorm. We have delivered jobs at Aqua Nature (320 homes), Gemelos 24/26/28 and Coblanca. We coordinate with the administrator, prepare quotes per home type (A/B/C), apply a 12-18% volume discount, phase manufacturing and produce a single works certificate for the community.

Will the windows withstand the September-October gota fría?+

Yes, that is why we use minimum water-tightness class E1200 (9A) — withstands 1,200 Pa combined with pressurised water. On SE/E orientations (facing Levante) we step up to class E1500. Double EPDM gasket + perimeter drainage + anti-rain bottom seal. Written no-leak warranty.

Can you process the grant paperwork?+

Yes. We deliver: itemised invoice broken down by section, before/after energy certificate, installer's declaration, data sheets for every product, CE marking and Eurocode 1 wind-load calculation. With that you have everything for NextGen IDAE, the income-tax deduction, the IVACE Generalitat grant and the Benidorm IBI rebate.

How does payment work? Do you accept financing?+

We accept bank transfer (including international SEPA/SWIFT), card and Bizum. Usual schedule: 50% on signing and 50% on completion (not before). For larger jobs (communities) we can split into 3 milestones. If you need bank financing with preferential rates for energy refurbishments, we can advise.
