Custom PVC Windows in Alicante & Costa Blanca
German-engineered & Spanish-manufactured PVC windows direct from our factory in Aspe. English-speaking technical team, free home survey, and 10-year guarantee across Alicante province.
Beat the Mediterranean Heat and Cut Energy Bills with PVC
Living on the Costa Blanca means enjoying over 300 days of sunshine a year. However, during the long summer months, older aluminum or single-glazed windows turn villas and apartments into green-houses. Running air conditioning all day results in exorbitant electricity bills, while drafty frames let winter winds and street noise disturb your peace.
At Grado Ventanas, we manufacture premium multi-chamber PVC window systems fitted with intelligent solar-control double glazing (Guardian Sun). Unlike aluminum, PVC is a natural thermal insulator that never conducts heat or cold. Combined with airtight multi-point compression seals, our windows keep your home cool in summer, warm in winter, and blissfully quiet all year round.
English-Speaking Advisors
No language barriers. We explain quotes, specifications, and energy ratings clearly in English from survey to completion.
Direct Factory Pricing
Manufactured directly in our Aspe workshop. No middleman commissions or third-party reseller markups.

Frequently Asked Questions
Do your advisors speak English?
Yes! We have dedicated English-speaking technical advisors who handle your consultation, measuring appointment, written quotation, and after-sales support seamlessly.
Can you carry out the installation while I am back home abroad?
Absolutely. Many of our international clients coordinate installations while they are in the UK, Scandinavia, Germany, or the Netherlands. We arrange key collection with your keyholder or agent, send daily WhatsApp photo and video updates, and leave the property spotless upon completion.
How much can I save on air conditioning bills?
Upgrading from old sliding aluminum windows to multi-chamber PVC with solar control glass typically slashes cooling and heating energy demand by 30% to 45%, providing an immediate and noticeable drop in summer electricity invoices.
