When it comes to replacing your windows, the glass you choose can make a big difference. Glass will typically make up 70% of your window, and it’s at the heart of controlling the flow of natural light, the level of safety and security, and of heat retention. It can even help protect furniture against fading.


Planitherm’s modern glazing can maximise your home’s comfort. Whether you’re looking for warmth, a peaceful night’s sleep or to enjoy a sun-filled room without overheating, Planitherm has the perfect high-performance glass for you.


It’s the UK’s leading energy-efficient glass and can be incorporated into any style of window frame.

Energy Standard – Keep your home warm and comfortable

Comfort – Choose better security and better sleep

Comfort Plus – For the perfect balance of light, warmth and comfort

ENERGY EFFICIENCY - With Planitherm, energy efficiency comes as standard.

A special coating on the glass helps stop heat escaping, so you’ll use less energy to keep your home warm. The Energy Standard and Comfort glazing captures and makes use of the warmth from natural daylight, while Comfort Plus helps limit and control it – ideal for very sunny rooms.

ENHANCED SECURITY - Help protect your family from break-ins and vandalism.

The high-security transparent layer on Comfort and Comfort Plus glass makes them much tougher to break through than standard, unlaminated glass. Used in an approved window frame, they’re designed to meet the official police security initiative ‘Secured by Design’ standard, so you’ll feel safer and more secure in your home.

NOISE REDUCTION - Make your home a peaceful respite from the world outside.

Perfect for bedrooms to ensure a good night’s sleep, a built-in acoustic layer keeps exterior noise exactly where it belongs – outside. If you live on a busy road or close to other disturbing sounds, noise control glazing should be on your list.

FURNITURE FADE PROTECTION - Keep your furniture looking newer for longer.

Prolonged exposure to ultra-violet light from the sun will contribute to your furniture and curtains fading over time. The hidden layer of protection on Comfort and Comfort Plus glass blocks out 99% of the sun’s UV rays. Think of it as sun-block for your sofa, curtains and carpets!

REDUCE OVERHEATING - Perfect balance of light and warmth.

Rooms with lots of glass will give you a great view, but the warmth from natural daylight can make it uncomfortably hot on sunny days. Our Comfort Plus glass has a special coating designed to keep out heat from the sun’s rays, for a comfortable, bright environment and greater control of your internal temperature. It’s particularly suited to south- and west-facing rooms with sunny aspects, or larger glazed areas such as bi-fold and patio doors.
