Planitherm glass: the invisible energy barrier
Because glass accounts for roughly 70% of a window’s surface area, it dictates the thermal performance, security and acoustic profile of your home. Elegant Windows Ltd uses Planitherm glass to give you energy efficiency as standard.
Planitherm’s coating technology manages the balance of natural light and thermal retention. It takes in solar heat from outside while reflecting internal heat back into your living space. Whether your priority is sound insulation for a peaceful night’s sleep, better home security, or preventing furniture fading from UV rays, our Planitherm glass options offer a complete climate-control package for your home.
How Planitherm glass works: read the transcript
Home should be a place you can’t wait to come back to. And if you’re replacing your windows, the glass you choose can make a big difference to how it feels. It helps keep indoor heat in and your home secure, affects how light flows through it, and can even make the most of free energy from outside. So make your home as comfortable as it can be with Planitherm High Performance Glazing.
From the world-class manufacturer behind iconic glazing, it’s the UK’s leading energy-efficient glass, with special coatings across the range that help stop indoor heat escaping. Our Energy Standard and Comfort glazing options capture and make use of the sun’s warmth. Comfort Plus helps limit and control it, so very sunny rooms, or those with lots of glazing, feel just right and don’t overheat.
To protect your family so you feel safer at home, Comfort and Comfort Plus glazing have a transparent layer that makes them tougher to break. They block out more noise than older-style double glazing too, making your home a peaceful respite from the world outside, and keeping in noise from inside, so you don’t disturb others either. And you’ll find furniture fade protection on selected Planitherm glazing options too.
So let’s look closer at the science behind the Planitherm comfort features. Imagine this sheet of glass represents Planitherm glazing options. Now we can see the difference a special coating on all Planitherm glass makes. Depending on the Planitherm package you choose, you get up to 63% better energy efficiency than older-style double glazing. To increase comfort, it can also capture and use heat from the sun.
In our Comfort and Comfort Plus packages, the glass has special layers that make it tougher to break and keep homes secure. These layers also reduce outside noise by up to 20%, and block 99% of UV rays to help stop your furniture, curtains and floor coverings fading, so they look newer for longer. Our Comfort Plus package controls the amount of the sun’s heat that gets let in, so sunny rooms and large glazed areas don’t overheat in the summer.
With these features grouped into three simple packages, Energy Standard, Comfort and Comfort Plus, it’s easy to find the Planitherm glazing solution for you, to fit any style of window frame. You may not see the difference, but you’ll certainly feel it.
VEKA window frames: there’s science behind the style: what the video shows
No sound. A sash window is drawn as a technical sketch with small notes around it, then filled in as a finished window. The VEKA logo stays in the corner, and the video ends on the words: There’s science behind the style.
There’s science behind the style
Our VEKA window systems pair traditional looks with modern engineering, so every frame is designed around how it performs as well as how it looks.
