Aluminium Windows: Everything You Need to Know Before You Buy

If you’re looking for aluminium windows in the South West, you’re not alone. Homeowners from Exeter to Dorchester are choosing aluminium for their sleek looks, energy efficiency, and long-lasting durability. At Lyme Bay Bifolds, we’ve supplied and fitted aluminium windows across towns like Axminster, Taunton, and Lyme Regis, so we know the questions that come up time and again. Here’s our expert guide to help you make the right decision.

1. Are Aluminium Windows Energy Efficient?

Yes. Modern aluminium windows use thermal breaks to reduce heat transfer, keeping homes warmer in winter and cooler in summer. Whether it’s a period cottage or a new build, good glazing makes a real difference to energy bills.

2. How Durable Are Aluminium Windows?

Aluminium is incredibly tough. It doesn’t warp or fade like timber, making it a popular choice for exposed coastal homes in places like Lyme Regis or Sidmouth. With the right finish, they can easily last 30–45 years.

3. What Maintenance Do They Need?

Almost none! Just a quick clean with warm soapy water. If you’re in a coastal area such as Weymouth or Seaton, a marine-grade finish helps protect against salty air.

4. Can Aluminium Windows Match My Home’s Style?

Absolutely. From contemporary extensions to Georgian houses, aluminium windows come in hundreds of RAL colours and can include features like astragal bars or flush frames to suit the property’s character.

5. What Are the Pros & Cons?

Pros: Strength, slim sightlines, low maintenance, recyclability, long lifespan.

Cons: Higher upfront cost compared to uPVC, and you need a quality installer to ensure performance.

Aluminium windows are stylish, energy-efficient, and designed to last decades. Whether you’re upgrading a seaside home in Lyme Regis or a family property in Taunton, they add both performance and value.
