Feature Description Energy Standard Comfort Comfort Plus
Thermally efficient A special coating on our glass helps stop heat escaping, so you’ll use less energy to keep your home warm.
Heightened security Our high-security transparent layer on Comfort and Comfort Plus glass makes them much tougher to break through than standard, unlaminated glass.
Noise Reductions 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 Our 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!
Reduces overheating A special coating on our glass helps stop heat escaping, so you’ll use less energy to keep your home warm. Our 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.

Energy Standard double glazing

Featuring a microscopic and heat restrictive coating on the inside, our Energy Standard double glazing is the ideal option for very sunny rooms that may be restricted by budget.

Compared to an uncoated unit of two glazing panes filled with air, Energy Standard double glazing impressively stops 56% more internal heat from escaping, meaning you could even save money on your heating bills.

Comfort double glazing

The way Planitherm’s Comfort double glazing option cleverly reduces noise and furniture fading, whilst heightening security, makes it the perfect choice for close-knit neighbourhoods and noisy street-facing rooms.

Thanks to a built-in, strengthening transparent layer, Comfort double glazing is tougher and provides 20% better noise reduction. It's intelligent manufacturing design blocks 99% of UV rays to protect your furniture from fading or damage from the sunlight.

Comfort Plus double glazing

Comfort Plus offers all of the features that Energy Standard and Comfort provide, as well as a special coating that effectively controls your room's internal temperature. This prevents overheating, meaning it is especially suited to south and west-facing rooms and large expanses of glass, such as bifold door and sliding glass door installations.

In comparison to standard double glazing, Comfort Plus’ unique invisible coating blocks out an impressive 50% of the sun’s external heat and retains 63% more internal heat.

What time of year is best to replace windows?

The best time of year to replace windows depends on your location and climate. However, generally, the best time of year to replace windows is during the spring or fall when the weather is mild and not too extreme. This is because extreme temperatures, such as heat waves or cold snaps, can make the installation process more difficult

How do I know if my double glazing needs replacing?

Here are some signs that your double glazing windows may need to be replaced: 1. Condensation: If you notice condensation forming between the panes of your double glazing windows, this can be a sign that the seals have failed, and the windows are no longer providing the insulation they should. 2. Drafts: If you feel drafts coming through your windows, it may indicate that the seals have deteriorated or that there are gaps in the frame or glass. 3. Damage: If your double glazing windows are damaged, cracked, or warped, this can affect their performance and insulation, and they may need to be replaced. 4. Noise: If you can hear a lot of outside noise through your windows, this may indicate that they are not insulated properly and that they need to be replaced. 5. Age: Double glazing windows typically last between 10 and 20 years. If your windows are approaching or past this age, they may be nearing the end of their lifespan and require replacement.6. Energy efficiency: If your energy bills are high, it may be due to the poor insulation provided by your double glazing windows. Replacing them with more energy-efficient windows can help reduce your energy costs.

Do you need permission to change windows in listed building?

Yes, you typically need permission to change windows in a listed building. Listed buildings are historic or architecturally significant structures that are protected by law in order to preserve their cultural heritage. As such, any changes or alterations to these buildings must be approved by the local planning authority or conservation officer to ensure that they do not negatively impact the building's historic character.

How much more efficient is double glazing than single glazing?

Double glazing is significantly more efficient than single glazing. Double glazing consists of two panes of glass separated by a layer of air or gas, which provides additional insulation compared to a single pane of glass. According to the Energy Saving Trust, double glazing can reduce heat loss through windows by up to 50% compared to single glazing. This means that you can significantly reduce your energy bills and carbon footprint by installing double glazing in your home.
