Thermal efficiency explained

Casement windows are designed with energy efficiency in mind, using insulated frames and advanced glazing to reduce heat loss. This helps maintain a stable indoor temperature throughout the year.

In winter, they help retain warmth inside your home. In summer, they reduce unwanted heat gain, improving comfort and reducing energy consumption across all seasons. Good thermal performance also reduces your home’s carbon emissions, as well as increasing its value.

uPVC vs aluminium casement windows

Choosing between uPVC and aluminium depends on your home, budget and design preferences.

uPVC casement windows are a popular choice for homeowners looking for excellent insulation and low maintenance performance. It’s a cost-effective synthetic material.

  • Affordable because it can be mass-produced
  • Elite thermal performance

Aluminium casement windows are made using durable metal, again easy to maintain. Aluminium is incredibly strong, and as a result can support slimmer sightlines, enabling more light in.

  • Slimmer sightlines mean more natural light
  • A good choice for thermal performance
