As the chill of winter still lingers across the UK, many homeowners find themselves grappling with the perennial challenge of rising energy bills. But what if your outdoor space - your balcony, terrace, or patio -could become an integral part of your home's thermal defense, reducing heat loss and significantly lowering your energy consumption?

At [Your Company Name], we specialise in bespoke architectural glass enclosures that offer not just unparalleled luxury and extended living space, but also a sophisticated, invisible benefit: superior thermal performance.


The Science of the "Thermal Buffer" - Glass Enclosure

Imagine adding a protective "second skin" to your home. This is precisely what a high-quality glass enclosure achieves. Research, such as that published by Babaee et al. (2016), demonstrates that in colder climates, enclosed glass balconies can reduce heating energy consumption by an impressive up to 46%.


How does this work? Our precision-engineered glass structures create a crucial "thermal buffer zone." Even without active heating, the temperature within a glazed enclosure can remain, on average, 5.0°C higher than the outdoor temperature during the winter months. This significant difference drastically reduces the amount of heat escaping from your main living areas, effectively mitigating the "thermal bridge" effect common in standard construction. It’s an application of the same principles found in high-performance architecture, like the Passive House standard, enhancing your home's overall thermal envelope.


Beyond Heat Retention: A Multi-faceted Investment

The benefits extend far beyond just warmth. Our premium glass enclosures also contribute to increased "facade tightness." Studies indicate that homes with glazed balconies experience a significantly lower infiltration rate -meaning fewer cold drafts permeating your interior - compared to those with open balconies.

But the advantages don't stop there:

  • Acoustic Comfort: Our bespoke glazing solutions don't just keep the warmth in; they also dramatically reduce noise pollution. You can expect a reduction of 20dB to 36dB from external sources, transforming your home into a serene sanctuary, even in bustling urban environments.


  • Property Value Enhancement: A high-quality, architecturally designed glass extension is not merely an expense; it's a strategic investment. Industry data suggests that bespoke glass conservatories and extensions can add 5% to 15% to your property's total value. For a multi-million-pound UK property, this means a significant return on investment, far outweighing the initial outlay, while simultaneously delivering tangible energy savings.


Harnessing Nature's Heater: Passive Solar Gain


Even on the chilliest, brightest February day, the sun holds immense, free energy. While traditional brick walls tend to reflect much of this energy, our advanced glass systems are designed to harness it.

Our enclosures allow beneficial short-wave solar radiation to pass through, where it is then absorbed by the surfaces within – your terrace floor, furniture, and even the air itself. This absorbed energy is re-radiated as long-wave infrared heat. Thanks to the "greenhouse effect," this invaluable heat becomes trapped within the enclosure. This "passive solar gain" effectively pre-warms the exterior façade of your main house. This means your central heating system doesn't have to work as hard to maintain comfortable indoor temperatures, translating directly into lower energy consumption and reduced bills.


Eliminating "Wind Chill" and Boosting Façade Efficiency

Wind is a silent culprit behind substantial heat loss. Known as "convection," when cold wind aggressively blows against your home's windows and doors, it strips away warmth at an accelerated rate, making your heating system work overtime to compensate.

Our glass enclosures provide an impenetrable shield against this phenomenon. By fully closing the system, you completely eliminate the "wind chill" factor on your primary façade. Your main exterior doors and walls are no longer battling a $2^\circ\text{C}$ gale; instead, they face a calm, tempered environment within the enclosure. This protective barrier ensures that the inherent U-value performance of your existing doors and walls is maintained at its optimal efficiency, keeping the warmth inside where it belongs.


The Alfresco Projects Technical Edge: The Confor Glass Roof


For architects, surveyors, and discerning homeowners focused on performance, our specialized glazing systems are key to maximizing these benefits:

Our Confor Glass Roof is a prime example of this engineering:

  • Outer Layer: 6mm Confor Tempered glass provides robust strength and an initial thermal barrier.

  • Core: A generous 10mm Air Gap serves as the primary insulating layer, crucial for reducing heat transfer.

  • Inner Layer: 4+4mm Laminated glass enhances safety, provides superior acoustic insulation, and further aids in heat retention.


Choosing an Alfresco Projects glass enclosure isn't just an aesthetic upgrade; it's a smart investment in your home's energy efficiency, comfort, and sustainable future. Experience the luxury of a warmer home and the satisfaction of lower energy bills, all while enjoying your stunning views year-round.
