So, What Are the Best Materials for Windows?
If you’re planning to upgrade your windows, one of the first decisions you’ll face is choosing the right frame material. With options like uPVC, aluminium, and timber-look finishes, it’s understandable to ask: what are the best materials for windows? The answer depends on your property type, performance requirements, budget, and style preferences.
In this blog, we explore the most common window materials used in UK homes, comparing their durability, insulation, maintenance needs, and cost to help you choose the most suitable option for your project.
1. uPVC Windows
Unplasticised Polyvinyl Chloride (uPVC) is the most widely used window material in the UK. It’s a cost-effective, low-maintenance option that offers excellent thermal performance and weather resistance.
Benefits:
- Affordability – uPVC is typically the most budget-friendly material on the market.
- Energy Efficiency – Modern uPVC frames are multi-chambered which reduces heat loss
- Low Maintenance – No painting or sealing required; just occasional cleaning.
- Versatility – Available in a variety of finishes, including timber-effect.
At Skyway Windows, we supply and install a wide range of uPVC frames in styles such as casement, flush, sash, and bay windows, providing high thermal efficiency and great value for money.
2. Aluminium Windows
Aluminium frames are becoming increasingly popular for their slim profiles, strength, and sleek appearance. While they tend to cost more than uPVC, they offer a contemporary look and long lifespan.
Benefits:
- Modern Aesthetic – Slim frames allow for larger glazing areas and minimal visual obstruction.
- Durability – Resistant to corrosion, warping, and weather damage.
- Low Maintenance – Powder-coated finishes don’t require repainting.
- Strength – Excellent structural integrity, especially for large or bespoke windows.
3. Timber-Look uPVC
If you want the appearance of traditional timber windows without the maintenance, timber-look uPVC can be an ideal middle ground.
Benefits:
- Authentic Look – Matches the appearance of original timber windows, ideal for period homes.
- No Rot or Warping – uPVC core provides resistance to moisture and decay.
- Insulation – Delivers the same multi-chambered energy performance as standard uPVC.
- Maintenance-Free – No need to sand, stain, or seal.
This option is especially useful for properties in conservation areas where traditional aesthetics are required but budget or practicality makes full timber unfeasible.
4. Timber Windows (Less Common in Modern Installs)
While genuine timber windows are still used in certain properties, particularly listed buildings, they are less common due to high maintenance requirements and higher costs.
Benefits:
- Visual Appeal – Offers a warm, authentic appearance suited to period properties.
- Natural Material – Ideal for those prioritising sustainable building practices.
- Customisable – Can be painted or stained in any colour.
However, timber needs ongoing care to avoid rot, warping, or peeling paint, and may not meet modern energy performance targets unless specified as high-performance hardwood.

How to Choose the Right Material
When asking what are the best materials for windows, it helps to consider the following factors:
- Style of Property – Period homes may suit timber-look uPVC or sash windows; modern properties often benefit from aluminium’s clean lines.
- Thermal Efficiency – Choose A-rated windows, ideally certified by the BFRC, to minimise heat loss and reduce energy bills.
- Maintenance Tolerance – If you prefer low-maintenance options, uPVC or aluminium are more suitable than traditional timber.
- Planning Restrictions – In conservation areas, specific materials or styles may be required. Your installer should guide you accordingly.
Legal and Installation Considerations
It’s vital that your new windows are installed in line with UK Building Regulations. Using a FENSA-registered installer ensures full compliance without the need for independent inspection. You can check accreditation for suppliers like Skyway Windows through the FENSA register. You can also refer to the LABC for wider compliance guidance.
