When it comes to choosing new windows for your Devon or Plymouth home, one of the most important decisions you’ll make is selecting the right material. Two of the most popular options are aluminium and uPVC windows, and each has distinct advantages depending on your property, budget, and aesthetic preferences. At Ace Double Glazing, we’ve helped thousands of homeowners across Devon, Cornwall, and Plymouth make this choice, and we’re here to guide you through the key differences.
Understanding uPVC Windows
uPVC (unplasticised polyvinyl chloride) has been the go-to choice for homeowners in Plymouth and across Devon for decades. These windows are made from a rigid plastic material that’s incredibly durable and low-maintenance. One of the biggest advantages of uPVC windows is their excellent thermal performance—they naturally insulate your home, helping to reduce energy bills during those cold Devon winters. uPVC windows are also highly affordable compared to aluminium alternatives, making them an attractive option for homeowners on a budget.
Another key benefit is that uPVC windows require minimal maintenance. Unlike timber frames, they won’t rot, warp, or need regular painting. A simple wipe-down with soapy water keeps them looking fresh for years. For families in Plympton, Plymstock, and across South Hams, this low-maintenance appeal is a major selling point. uPVC windows are also FENSA approved and come with our 10-year insurance-backed guarantee, giving you complete peace of mind.
The Appeal of Aluminium Windows
Aluminium windows have gained popularity in recent years, particularly among homeowners seeking a more contemporary aesthetic. These windows feature slim frames and clean lines that create a modern, minimalist look—perfect for new builds or properties undergoing significant renovation. If you’re looking to make a bold architectural statement in your Plymouth or Devon home, aluminium windows deliver that premium appearance.
Aluminium is also incredibly strong, which means frames can be thinner without compromising structural integrity. This translates to larger glass areas and more natural light flooding into your home—a real advantage for properties in Exeter, Saltash, and Torpoint where maximising views and daylight is important. Aluminium windows are also highly weather-resistant and won’t corrode, even in coastal areas like Cornwall.
Thermal Performance: A Critical Consideration for Devon Homes
Here’s where the comparison gets interesting. Aluminium is a highly conductive material, meaning heat passes through it more easily than uPVC. To address this, modern aluminium windows use thermal breaks—insulating strips between the inner and outer frames—to improve energy efficiency. However, uPVC windows still typically outperform aluminium in terms of pure thermal insulation, which is why they remain the preferred choice for homeowners prioritising energy savings across Devon and Cornwall.
If you’re concerned about rising energy bills in your Plymouth home, uPVC windows will generally deliver better results. That said, high-quality aluminium windows with advanced thermal breaks can still provide excellent insulation, especially when paired with double or triple glazing.
Cost Comparison: Budget vs Investment
Cost is often the deciding factor for many homeowners. uPVC windows are significantly more affordable than aluminium alternatives—typically 30-50% cheaper. For families in Plympton, Ivybridge, and across South Hams looking to replace multiple windows, this cost difference can be substantial. At Ace Double Glazing, we pride ourselves on offering competitive pricing without compromising on quality, and our FENSA-approved uPVC windows represent excellent value.
Aluminium windows command a premium price due to their superior aesthetics and durability. However, if you’re investing in a high-end property renovation or building a new home in an upmarket area of Devon or Cornwall, the investment in aluminium may be justified by the visual impact and longevity.
Maintenance and Longevity
Both materials are durable, but maintenance requirements differ. uPVC windows need occasional cleaning but are otherwise maintenance-free. Aluminium windows, while extremely durable, may require more attention if you live in a coastal area—salt spray can affect the finish over time, though modern powder coatings provide excellent protection.
Both uPVC and aluminium windows, when installed by professionals like our team at Ace Double Glazing, will last 20-30 years or more. Our 10-year insurance-backed guarantee covers both materials, ensuring your investment is protected whether you choose uPVC or aluminium.
Which Material is Right for Your Devon or Plymouth Home?
Choose uPVC windows if you prioritise energy efficiency, affordability, and low maintenance. They’re ideal for period properties, family homes, and any property where budget is a consideration. uPVC is the smart choice for most homeowners across Plymouth, Devon, and Cornwall.
Choose aluminium windows if you want a contemporary aesthetic, maximum natural light, and don’t mind paying a premium. They’re perfect for modern new builds, coastal properties in Cornwall and Saltash, and homes where architectural design is a priority.
At Ace Double Glazing, we offer both uPVC and aluminium windows, and our team can help you weigh the pros and cons based on your specific property and needs. Whether you’re in Exeter, Torpoint, Elburton, or anywhere across Devon and Cornwall, we’re here to provide expert advice and professional installation.
