High-Performance Double Glazing

Alaskan Windows specialises in high-performance products that enhance the comfort of your home. Our products are designed to provide quality performance, utilising a fantastic profile that offers thermal-efficiency and durability.

We offer a stunning collection of fabulous uPVC windows and uPVC doors that are manufactured using Liniar profile technology, the UK’s finest brand. These market-leading double glazing profiles provide a multitude of benefits for homeowners around London.

Its state-of-the-art profile features a four chambered design that is thermally-efficient and able to achieve incredible energy ratings of up to A+! The innovative design incorporates a patented double-action ‘bubble’ gasket offering an improved seal.

Another benefit of our thermally-efficient uPVC double glazing is its eco-friendly composition. The entire frame is lead-free and entirely recyclable, which ensures a sustainable manufacturing process to lower carbon footprint. The great benefit is they can be reused.

Our double glazing is high performance because of its incredible durability due to the inherent robustness of uPVC. We provide a sustainable solution that is energy-efficient and enhances the security of your London home.

We also partner leading composite door manufacturer Endurance to bring homeowners in London an incredible range of long lasting, hard wearing, beautiful composite doors that are perfect for any type of property.

Recent Customer Feedback

  • Perfect professionalism from first point of contact to cleaning up after work. Very consistent and thorough in communication. Prices are upfront and fair and most importantly - finished product is perfect. So happy I found them on Checkatrade and decided to solicit a quotation from them. Local London shops and nationwide leaders didn't measure up!
