Conservatory in Los Alcazares, Murcia.
Los Alcázares sits in one of the sunniest, most arid stretches of the Costa Cálida, where summer temperatures routinely climb to 31–33°C and the sun beats down almost all day long.
For this homeowner, the glass conservatory looked perfect on paper—a bright, airy extension with panoramic views. In reality, though, it became practically off-limits from late morning right through to evening once the summer heat set in.
Real Case Study: Hanita Titan 20 XTR on a Conservatory in Los Alcázares, Murcia.
The Challenge: A Conservatory That Became an Oven
Los Alcázares enjoys one of the sunniest, driest climates on the Costa Cálida, with summer highs regularly reaching 31–33°C and intense, direct sunlight for most of the day. For this client, their glass conservatory was a beautiful space in theory—but in practice, it was unusable from late morning until evening in summer.
Before installation, the internal temperature in the conservatory consistently hit 33°C, even with curtains drawn and fans running. The heat radiating from the glass made it uncomfortable to sit, eat, or relax. Glare on screens and hot spots on furniture were constant issues. The client needed a solution that would keep the space comfortable without sacrificing natural light or the view of the garden and sky.
The Solution: Hanita Titan 20 XTR Exterior Window Film
We recommended Hanita’s Titan 20 XTR, a premium exterior solar control film designed specifically for high-heat, high-sun environments like Murcia. Titan 20 XTR is a dual-reflective, metallised sputtered film that rejects up to 71% of total solar energy while transmitting 20% visible light, giving a balanced, neutral appearance from both inside and out.
Key technical benefits that mattered for this conservatory:
- Total Solar Energy Rejected: 69%
- UV Block: 99%, protecting skin and furnishings
- Visible Light Transmitted: 19% ( hardly any difference to see interior then without the window film.
- Glare Reduction: 79%, making the space usable even at midday
- Shading Coefficient: 0.36 and Solar Heat Gain Coefficient (G-value): 0.31, indicating strong heat control on single-pane glass typical of many conservatories
Installation and Client Experience
The conservatory had a mix of vertical windows and a pitched glass roof, all single-glazed. We prepared the glass thoroughly, then applied Titan 20 XTR to the exterior of every pane, paying special attention to the roof sections where solar gain is highest.
From day one, the client noticed a dramatic difference:
- The “oven effect” disappeared; the space felt shaded but still bright.
- Glare on the TV and laptop screens was vastly reduced.
- Fabrics, wood furniture, and flooring no longer faded or felt hot to the touch.
- The exterior finish gave a modern, slightly reflective look that blended well with the white frames and the coastal aesthetic of Los Alcázares.
- Measured Results: From 33°C to 25°C
We monitored temperatures before and after installation on comparable sunny summer days, using the same time windows and with internal blinds in the same position.
- Before film: peak internal temperature reached 33°C in the early afternoon.
- After film: peak internal temperature stabilized around 25°C under the same conditions.
That’s an 8°C reduction in peak heat—right in line with, and even slightly above, the 4–8°C average indoor temperature drop reported in similar Spanish case studies, with peaks up to 8–10°C in very sunny rooms. In practical terms, the conservatory went from “avoid at all costs” in summer to the client’s favourite room for morning coffee, afternoon reading, and evening relaxation. The client gave us a 5-star verified by trustindex review. Read our reviews.
Energy and Comfort Benefits
Beyond comfort, the temperature drop translates into real energy savings. Research on solar control films in Mediterranean climates shows cooling energy reductions of roughly 22–35% depending on the film and building. In this conservatory, the air conditioning now runs less often and at higher set points, cutting electricity use and wear on the system.
The 99% UV block also protects the client’s health and extends the life of soft furnishings, an important consideration in a room that receives direct sun for most of the day.
“The conservatory is now usable all day in summer. Before, we couldn’t even go in there after 11 a.m. Now it’s the room we use the most.
The temperature difference is incredible—what used to be 33 degrees is now around 25, and the light still feels natural. It was one of the best investments we’ve made in the house.”
