Glasses for your conservatory
The choice of glazing determines the use of the conservatory – from a greenhouse to a living room.
Single glass Ug-value 6.0 W/m2K according to EN 673
consists of float glass; it is not used for heated conservatories because of the lack of thermal insulation function and the associated formation of condensation. It is used in greenhouses and as a laminated safety glass combination also for roofing.
Insulating glass Ug-value 3.0 W/m2K according to EN 673
usually consists of two 4 mm thick float glass panes which are joined airtightly by means of a spacer frame forming the gap between the panes. A desiccant in the cavity of the spacer frame binds the moisture of the air contained in the space between the panes.
Due to insufficient thermal insulation, these glasses are no longer used today
Thermal insulation glass Ug-value 1.1 W/m2K according to EN 673
The structure of the glass panes corresponds to that of the insulating glass. Commonly used inter-pane spaces are 12 – 16 mm. The significantly higher thermal insulation compared to insulating glass is achieved by an almost invisible thermal radiation reflecting layer of metal oxides and a gas filling in the space between the panes. In overhead glazing, the room-side pane is laminated safety glass.
Currently, the still common glazing for conservatories, windows, doors, etc..
Super warm glass Ug-value 0.5 W/m2K according to EN 673
The structure of the panes corresponds to that of thermal insulation glass. However, 3 panes are connected to each other via 2 spacer frames and 2 inter-pane spaces (inter-pane spaces) to form a pane unit. The extreme thermal insulation is achieved by two heat-reflecting functional layers and inert gas fillings in the inter-pane spaces. In terms of the current energy saving regulation (EN 673), this glazing is essential for living spaces.
At e.g. – 10° outside temperature and 21° inside temperature, the pane in the interior is still +19° warm. A cold radiation is no longer noticeable and the desired comfort is ensured even at low outdoor temperatures.
Vacuum glass Ug-value 0.5 W/m2K according to EN 673
The pane structure corresponds to that of the thermal insulation glass. Two 4 mm thick float glass panes, one of which has a heat-reflecting layer, are joined together airtightly using spacers 1 mm thick.Two 4 mm thick float glass panes, one of which has a heat-reflecting layer, are joined together airtightly using spacers 1 mm thick. A vacuum is created in this weld gap. The air pressure acting from outside is absorbed by numerous barely visible metal needles.
Currently, these glasses are available with U-values of 0.3 – 0.5 W/m2K. There are still significant restrictions on pane dimensions and glass combinations.
functional glasses
Sun protection glass
On the one hand, the unbearable heating of your winter garden in summer must be prevented, on the other hand, as much light as possible should illuminate the rooms. You can achieve this goal with solar control glass. Short-wave thermal radiation is reflected to a high degree by the solar control glass, while daylight can pass largely unhindered. (see also g-value)
Safety glass
Beautiful houses are increasingly visited by uninvited guests who prefer to enter through the window. Here, effective protection against burglary is provided by the security glass.
Dimmable glasses
If the transparency of the glass is not permanently desired, the use of electrochromic glass is an option.
Here, a nanostructured coating turns blue when an electrical voltage is applied, thus reducing the transmission of sunlight.
This not only preserves privacy, but also provides sun protection.
Soundproof glass
90 % of all Germans now feel annoyed by noise and long for peace and quiet.
Depending on the location, use and noise source, different requirements are placed on the glazing.
Sound insulation values of up to 52 dB (decibels) can be achieved.
Glasses with self-cleaning effect
This glass actively cleans itself continuously – with the help of daylight and rain.
And it does this so well that the glass needs to be cleaned much less frequently.
A unique decision that saves time, money and nerves for the life of the window. Details about the Activ Glass…
Ug-value / g-value
The Ug value
The smaller the Ug value, the better the thermal insulation.
The heat transfer coefficient – Ug-value (often still referred to as k-value) is the central physical parameter when determining the heat loss through a building component. The heat transfer coefficient indicates the amount of heat that passes through 1 m2 of a building component per hour at a temperature difference of 1 K between the adjacent room and outside air.
g-value
The higher the g-value, the greater the solar energy gain.
The g-value is the total energy transmittance of glazing for solar radiation in the wave range from 300 nm to 2,500 nm.
It is expressed in % and indicates what percentage of solar energy the glass lets through.
Activ Glass - Self-cleaning
Pilkington Activ™ actively cleans itself continuously – with the help of daylight and rain.
Without the use of cleaners and additives.
And it does this so well that the glass needs to be cleaned much less frequently.
And when it does, it is often enough to simply spray it with water without sanding it down.
A one-off decision that saves time, money and nerves for the life of the window.
Pilkington Activ™ is the glass of the future that is already inspiring thousands worldwide.
Your advantages
- More leisure time through less frequent window cleaning
- Organic contaminants are actively decomposed
- Better visibility in the rain
- No water stains after the rain
- No leathering required
- Fogging less from the outside
- Cost savings (window cleaner)
And that's how it works:
- Step: Organic dirt is removed by the UV radiation of sunlight and with the help of the special coating on the glass surface.
- Step: Rain rinses off the loosened dirt completely – spotless.
- Step: Clean!
