Our standard UPVC windows are impressive enough, but our UPVC EXTREME windows take things to a different level in terms of the security and energy efficiency they offer. A+ rated as standard for a comfortably regulated temperature, our clever glazing technology prevents internal heat from escaping, whilst harnessing just the right amount of heat from the sun.
After the installation of these EXTREME windows, your home couldn’t be more secure. In addition, locking in heat, out sculpted frames house chambers for added insulation and durability that lasts a lifetime.
To ensure they justify their ‘EXTREME’ tag, we performed hours and hours of testing and they came through each assessment with flying colours. Take EXTREME measures and put your faith in these windows to deliver the very best all-round window performance.
