What Are The Benefits Of Double Glazing In Norwich?

KLIC Home locking systems are Secured by Design, and all of our double glazed uPVC windows, aluminium windows, or otherwise, will benefit from this security. All components have been purpose designed and selected to ensure the performance of our double glazing products can surpass all standards laid down for enhanced security. They’re also durable, long-lasting and pleasing to the eye.

All the windows we manufacture feature locking points that secure the window in all four corners and sides of the frame. They also utilise an internally glazed design that prevents the glass from being removed from the outside, meaning they do a superb job at protecting your home from potential intruders.

Installing KLIC Home ‘A’ energy-efficient windows can significantly improve the sound quality in your home. With high-performance glazing, sound resistance is enhanced and a higher quality of air, noise and light filtration is achieved – ultimately providing you with a more comfortable internal environment.

Our energy-efficient windows cut heat loss through windows and can significantly reduce fuel bills for householders. Just by reducing the running time of your heating system and locking in thermal energy, you can achieve a warmer, healthier home.
