Energy efficient double glazed windows

One of the best ways to cut your energy bills is to replace old windows with modern, energy efficient uPVC windows and doors. Great workmanship with the best materials will help keep your home warmer in the winter months, and help reduce your heating bills.

Windowlines windows have top environmental credentials. They've been awarded an energy rating of A and are made of materials that achieved a British Fenestration Rating Council (BFRC) Green Guide A rating. Not only that, they have excellent U-value ratings and the very best Window Energy Rating (WER).

Save on energy bills with double glazed windows

More than 30 years of knowledge and expertise go into the design of Windowlines casement windows.

As well as improving your home’s energy efficiency, you’ll be helping the environment. According to the Glass & Glazing Federation:

“homes are currently responsible for around 28% of UK CO2 emissions, contributing to the impact of climate change."

What do the Building Regulations say about replacement windows?

From 1 October 2010, you’re only allowed to install replacement windows that have a WER energy rating of C or higher. So you can be confident our thermally efficient windows will satisfy Building Regs.

By replacing your existing windows with our uPVC windows, you’ll make your rooms quieter, more secure and more thermally efficient.

Improved energy efficiency is just the start of what our windows will do for your home.
