When it comes to upgrading your windows, choosing the right material for double glazing is crucial. Each material has its unique benefits, costs, and drawbacks, making it essential to compare them to find the best fit for your home. In this blog, we’ll explore the top five materials used for double glazing, focusing on cost, durability, energy efficiency, and aesthetic appeal.
🌟 1. uPVC (Unplasticized Polyvinyl Chloride)
Cost
- Average Cost: £250 - £500 per window
Durability
uPVC is known for its robustness and resistance to weathering, rot, and corrosion. This material can withstand harsh environmental conditions without compromising its structural integrity.
Energy Efficiency
uPVC frames provide excellent thermal insulation, helping to keep your home warm in winter and cool in summer. This can significantly lower your energy bills over time.
Pros:
- Affordable and low-maintenance
- Variety of colours and styles available
- Excellent insulation properties
Cons:
- Limited aesthetic appeal compared to wood or composite options
- Can become discoloured over time with prolonged exposure to sunlight
🌳 2. Wood
Cost
- Average Cost: £500 - £1,000 per window
Durability
Wood is a classic choice that offers natural beauty but requires regular maintenance to prevent rot and damage from insects or moisture.
Energy Efficiency
Wooden frames provide great thermal performance and are an excellent insulator, keeping homes warm and reducing energy costs.
Pros:
- Attractive and timeless appearance
- Good insulation properties
- Can be painted or stained to match your home’s decor
Cons:
- Requires regular maintenance, including painting and sealing
- Prone to warping and rot without proper care
🏢 3. Aluminium
Cost
- Average Cost: £600 - £1,200 per window
Durability
Aluminium is incredibly strong and long-lasting. It is resistant to corrosion and can withstand the elements, making it a popular choice for modern constructions.
Energy Efficiency
While aluminium is not as naturally insulating as uPVC or wood, modern techniques such as thermal breaks can improve its energy efficiency significantly.
Pros:
- Sleek, modern appearance
- Low maintenance and long-lasting
- Strong and lightweight, allowing for larger window designs
Cons:
- Higher initial cost compared to uPVC
-
Requires thermal breaks to enhance insulation
🛠️ 4. Composite
Cost
- Average Cost: £700 - £1,300 per window
Durability
Composite windows combine multiple materials to leverage their strengths, resulting in a highly durable and low-maintenance product.
Energy Efficiency
Composite frames offer excellent energy efficiency, as they can be designed to optimize insulation while maintaining structural integrity.
Pros:
- Combines benefits of different materials for enhanced durability
- Low maintenance and resistant to weathering
- Versatile design options available
Cons:
- Higher price point than uPVC and wood
- Can vary in quality depending on the manufacturer
🏡 5. Fibreglass
Cost
- Average Cost: £700 - £1,500 per window
Durability
Fibreglass is incredibly strong and can withstand extreme weather conditions without warping or cracking, making it a durable option.
Energy Efficiency
Fibreglass frames offer excellent insulation properties, rivaling those of wood and uPVC while being less prone to expansion and contraction.
Pros:
- Highly durable and resistant to warping
- Low maintenance and long-lasting
- Can be painted to match your home’s decor
Cons:
- Higher initial investment
- Limited availability compared to more traditional materials
