Triple glazing. A quieter and warmer home.

Improve your home with triple glazing and take advantage of the Corsham Building Plastics Triple for Double promotion from April to June 21st, 2024. This promotion offers a free upgrade to triple glass.

If you’re considering new windows and doors for your home, Internorm triple-glazed windows present a great opportunity to have the latest-generation windows with superior triple-glazing technology—at the cost of double-glazing.

Why Choose Internorm Triple Glazed Windows?

Investing in your home is a decision that brings long-term benefits, not only in terms of aesthetics and comfort but also when considering energy efficiency and savings on utility bills. At Corsham Building Plastics, we want to help you get even better new windows and doors with the advanced Internorm range, designed from the ground up as sustainable, secure and highly energy-efficient windows.
Unlike many aluminium and PVCu windows, Internorm windows aren’t regular double-glazed with a triple unit added. Internorm is designed from the outset to take this enhanced thickness and higher-performance glass. Made in Austria and using triple glass since 1979, Internorm windows have transformed the glazing industry, focusing on durability, security, and unparalleled thermal performance.
Internorm triple-glazed windows provide some of the best-designed windows available, with some outstanding benefits.

A combination of the two best window materials

Fine wood inside provides an ambient warm-to-the-touch feel with the beauty of natural wood. Aluminium outside provides protection and virtually unlimited colour choices. This hybrid design provides the best thermal performance and lowest U-values. You benefit from an ambient indoor feel and a low-maintenance window outside in your preferred colour.

Superior Thermal Efficiency

Internorm windows achieve U-Values as low as 0.8Wm2K, surpassing current UK Building Regulations requirements. Other triple-glazed aluminium and PVCu windows offer typical U-Values of only 1.2 or 1.4. This translates to a warmer home, lower fuel consumption, and constant ambient temperatures.

Enhanced Security

Featuring PAS 24 and SBD security standards, along with the option for laminated glass for even better performance, triple-glazed windows offer exceptional security and peace of mind.

Optimal Design

From a choice of woods and exterior colours to multi-functional windows. Internorm windows support larger dimensions than aluminium or PVCu windows. You benefit from better window functionality, aesthetic appeal, more glass and less visible frames.

Airtight Sealing

With triple gaskets, Internorm windows and doors provide an airtight seal, significantly reducing energy loss and enhancing your home’s overall energy efficiency.

Acoustic Performance: The depth of the cavities and the glass’s thickness, along with laminated glass options, improve the acoustic performance, offering a quieter and more peaceful living environment.
