Energy efficiency is one of the biggest factors to consider when choosing new windows and doors, especially with rising energy costs and increasing focus on improving home performance across the UK.

​

At Coastview Windows, our uPVC windows and doors are designed to meet and exceed current UK Building Regulations, delivering strong thermal performance as standard. All products are manufactured using trusted systems such as Profile 22, ensuring a minimum Window Energy Rating of C, with options available to achieve higher ratings for even greater efficiency.

​

Window Energy Ratings (WER) range from A++ to E and provide a simple way to understand how well a window performs in terms of heat retention and overall efficiency. The higher the rating, the better the insulation helping to reduce heat loss, lower energy bills and create a more comfortable living environment.

Because every window and door we supply is made to order, we can also enhance the specification to suit your project. Whether you’re working on a refurbishment, new build or retrofit scheme, we can offer higher-performing glazing and upgrades to achieve the best possible energy efficiency for your property.
