Why people choose us in Murcia
Murcia city is not the coast: it is inland Spain with extreme summers (up to 42 °C) and very dry air. The priority is not salinity — it is controlling solar heat gain and cutting the HVAC bill, which in many homes in Vistabella or La Flota tops €280/month in July-August.
In Murcia we recommend glass with solar factor g ≤ 0.32 (SunGuard SN 40/23 or ClimaGuard Solar): it blocks up to 60% of radiant heat without darkening the room.
Murcia is climate zone B4 (hot-hot-hot), stricter than the coastal B3. Our windows meet Uw ≤ 1.4 W/m²K with the solar factor regulated by CTE DB-HE 2019.
We cut and assemble in our own workshop in Alicante: 80 km to Murcia city via the AP-7. No middlemen = 15-22% less than franchised chains buying from catalogue.
We have refurbished entire buildings in Espinardo (near the University of Murcia) and El Carmen. Block-by-block orders with a schedule signed off by the property manager and a single certificate.
We process NextGen IDAE Region of Murcia (up to 80%), the 60% IRPF deduction for energy works and INFO (Instituto de Fomento) grants up to 31/12/2026.
Ten-year warranty on the profile + 5 years on Roto NX hardware + 2 years on seals. Signed contract. If you get condensation, warping or leaks, we return to Murcia at no charge.
The climate rules everything
Murcia city records 300 sunny days a year, very low humidity (55% relative humidity), extreme summers up to 42 °C and day-night swings of +15 °C in spring and autumn. The dominant wind is the dry, cold northerly Cierzo. This generates problems specific to inland Spain:
A correct window for Murcia should have Uw ≤ 1.4 W/m²K, solar factor g ≤ 0.35 and class 4 air tightness.
Local coverage
Free on-site survey within 48 h in these parts of the Region of Murcia. If your property is in an outlying district or nearby town (Molina, Alcantarilla, Beniel), we will travel out too — just ask, no obligation.

What comes as standard
Regulatory compliance
Every window leaves the workshop with CE marking and the documentation required by the CTE. For Murcia's B4 zone the requirements are the strictest in Spain — we deliver a digital and paper dossier for your ITE, IRPF or IDAE subsidy.
Declaration of Performance (DoP) per model and project. Without it, no window has been legal in Spain since 2014.
The windows we install in Murcia meet Uw ≤ 1.8 W/m²K (B4 required) and most reach 1.0-1.2 W/m²K with triple glazing (class A+).
Profiles with the AENOR N mark, manufactured to UNE EN 12608. Traceability by batch and by project.
Guardian Glass with g ≤ 0.32: meets the CTE requirement in zone B4 to prevent summer overheating.
Spanish association of facade and window manufacturers: industry-wide backing for the delivered product.
Team trained at Kömmerling Academy and Cortizo certified. Installation follows the manufacturer's protocol.

The team that comes to your home
VentanaCosta does not subcontract: the surveyor who measures is on the payroll, and so is the installer. This matters in Murcia because every district has its own quirks — La Flota communities with strict schedules, heritage buildings in the city centre, Vistabella urbanisations with internal rules.
We have been installing across Alicante and the Region of Murcia since 2010. Fourteen years, 3,200+ homes, zero court cases.
Surveyor
18 years measuring in Levante and the Region of Murcia. Speaks Spanish and Catalan.
Multilingual liaison
Spanish, English, Russian. Coordinates work for foreign clients in Murcia.
Lead installer
Kömmerling Academy + Cortizo certified. Team of 4.
Frequently asked questions
From quote sign-off to handover: 10-14 working days of manufacture + 1-2 days of installation per home (typical flat). For chalets in La Alberca or El Palmar with full enclosures: 2-4 weeks. For an Espinardo community we plan block by block, 2-3 weeks each.
No. On-site survey + fixed quote are free and with no obligation across Murcia city, the outlying districts (La Alberca, El Palmar, Beniaján, Cabezo de Torres) and nearby towns such as Alcantarilla, Molina de Segura and San Pedro del Pinatar.
For Murcia city we recommend triple glazing with solar control (4/16/4/16/4 with SunGuard) on S, SW and W orientations: B4 is the toughest climate zone in Spain and the low solar factor (g ≤ 0.32) blocks radiant heat. For N and NE, double low-e glass is enough. We tailor the recommendation to your specific facade during the survey.
Yes. We use wood-effect PVC or aluminium lacquered in a RAL colour approved by Murcia town hall heritage department. We advise on the permit process, draft a technical memo if needed and deliver a certificate of aesthetic compliance.
Yes. We provide: itemised invoice by chapters, before-and-after energy certificate where required, installer's declaration, product datasheets and CE marking. That gives you everything for NextGen IDAE Region of Murcia, IRPF, INFO and the Murcia town hall IBI rebate.
On our closed Murcia projects with triple solar-control glazing, the July-August AC bill drops 40-55%. From €280 you typically go down to €130-170. Energy ROI in Murcia is faster than on the coast (5-7 years) precisely because of the inland summer extreme.
We accept bank transfer, card and Bizum. Standard payment terms: 50% on signing and 50% on installation completion (not before). For larger projects we can split into 3 milestones. If you need bank financing, we recommend lenders offering preferential rates for energy refurbishment — some Murcia city branches have dedicated lines.
We dismantle them, remove them and take them to an authorised waste facility in the Region of Murcia. Removal cost is included in the quote — it does not appear as an "extra" at the end. If your homeowners' association needs a waste-management certificate for the AGM, we provide it.
