Upgrade To Performance Glazing


Our glazing option from Planitherm will maximise the comfort of your home. Whether you’re looking for additional warmth, a more quiet home, or if you want to enjoy a sun-filled room without overheating, Planitherm is the perfect high-performance glass.

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


PLANITHERM is a new generation of energy saving window glass that uses advanced coatings to retain more internal warmth whilst capturing free energy from natural daylight.

Using PLANITHERM, you can have A-rated windows installed for around the same cost as less energy-efficient windows.

A staggering 26% of all domestic heat loss escapes through the windows, so A-rated energy efficient windows could save you up to 28% a year on your heating bills compared to traditional windows and frames.

If you are planning to replace your existing single glazed or double glazed windows, and you want the best possible choice for energy savings, get in touch.

How Planitherm Works


Planitherm Comfort

Disturbed by road noise? Concerned about security?

Choosing Planitherm Comfort may be the answer.

It has all the benefits and features of the Energy Standard glass, but a built-in transparent layer makes Comfort glass much tougher to break through than standard, unlaminated glass.

Ideal for bedrooms or street-facing rooms, the layer also provides 20% better noise reduction than older-style double glazing, so you’re sure of a good night’s sleep.

It stops 56% more internal heat escaping and can even protect furniture from fading, blocking 99% of damaging UV rays.

Planitherm Comfort Plus

Comfort Plus glass provides the perfect balance of light, warmth and comfort. An invisible coating blocks out 50% of external heat from the sun while keeping in 63% more internal heat.

It’s ideal in sunny south- and west-facing rooms or for large glazed areas such as bi-fold or patio doors, making your home cooler in summer and warmer in winter.

A built-in transparent layer also makes Comfort Plus harder to break through, and provides up to 20% better noise reduction than older-style double glazing so you’re sure of a good night’s sleep.

It can even protect furniture from fading, blocking 99% of damaging UV rays**.
