Everything about the glass of your conservatory

When glazing your greenhouse, you often have a choice of greenhouse glass, safety glass or polycarbonate. Depending on the function of the greenhouse, the environment and your specific wishes, proper sealing can be recommended. See the overview drawing for the advantages and disadvantages per seal.

1) Gardener's glass

The use of greenhouse glass has been used for decades and is popular among hobby growers. Glass has the advantage that it allows a lot of light to pass through (about 90%), which is good for the crops in the greenhouse. Moreover, you can keep an eye on the cultivation results from outside the greenhouse!

Tolerances:
Garden glass has a long history. Glass quality and its application go hand in hand. The quality of garden glass is very different from, for example, the glass used in homes. Different tolerances apply to garden glass: the thickness is not exactly the same everywhere, it can vary slightly. The glass may also show air bubbles or streaks. This is simply part of gardeners' glass. The mentioned tolerances do not affect the strength or quality of the glass

Difference:
Other sealing options are: float glass, safety glass or polycarbonate. The biggest advantage of garden glass is the price. Gardeners' glass is much cheaper than the alternatives mentioned. Garden glass also differs from the rest in terms of dimensions: the largest pane size is 610 x 610 mm and has a thickness of 3 mm.

Installing glass:
Installing garden glass is very simple. Because we work with small panes, we use the traditional method of glazing: first the frame is provided with rubber or foam rubber in the right locations, then the glass is 'stacked like roof tiles'. To enable 'stacking', glass hooks are used, and the windows are fixed using glass clamps.

Safety tip!
Gardeners' glass has sharp edges, so always use good gloves when installing.

Durable
(Gardeners) glass is extremely durable. It is highly resistant to scratches, atmospheric and chemical influences, as well as cleaning agents. Gardeners' glass has an insulation value of approximately 6 W/m² K.

2) Safety glass

The most commonly used type of glass is safety glass. This allows you to benefit from the benefits of glass, but also takes safety in and around the greenhouse into account. Ideal in the city, a tree-lined area, or when there are children around.

Thermally treated:
Safety glass is created because float glass is thermally treated. The appearance remains exactly the same, only if you break you will immediately notice the difference: safety glass crumbles into 1000s of blunt particles. The structure is similar to what you encounter in house construction. It is even in thickness and free from impurities. That is the quality of safety glass.

Difference with garden glass:
In addition to safety glass, garden glass can be chosen. Safety glass combines the advantages of glass, good light transmission (approximately 90%), and your desire for a safe environment in and around the greenhouse. Safety glass is up to 6 times stronger than garden glass and will shatter completely into blunt particles if broken. Safety glass is also supplied polished, which means that the edges are rounded and no longer sharp. Depending on the greenhouse model, safety glass is supplied in a thickness of 3 or 4 mm.

Installing glass:
Installing safety glass is very easy. Because we always work with large panes and not with small stacked panes of garden glass. Glass clamps, sealing rubber or plastic glazing strips can be used to install the safety glass. Fitted windows are often used on the facade sides, using plastic stacking strips (H-profile).

Durable:
Safety glass is very durable. It is highly resistant to scratches, atmospheric and chemical influences, as well as cleaning agents. Safety glass has an insulation value of approximately 6 W/m² K.

Disadvantages of safety glass:

• - More expensive than gardeners' glass
• - A glass seal can lead to crop burning in a number of plant species. This can be prevented by installing screen mesh, chalking or installing polycarbonate instead of glass.
  
  

3) Polycarbonate

A plastic seal can be a very good alternative to the options available in glass. Polycarbonate is particularly strong, lightweight, insulates and offers optimal safety in and around the greenhouse. This double-walled seal is available in different thicknesses.

Insulating:
Polycarbonate has a completely different appearance than horticultural or safety glass. Polycarbonate is not transparent and has limited light transmission. This offers you a feeling of privacy in the greenhouse and it provides diffuse light. The latter is good as a prevention against crop burning. Thanks to the good insulation value of polycarbonate, the growing season in the greenhouse is brought forward and extended.

Difference:
Polycarbonate is a serious alternative to glass sealing. This plastic seal is always double-walled and can be supplied in different thicknesses (4/6/8/10 mm). Depending on the thickness, the insulation value of polycarbonate increases. The light transmittance of polycarbonate varies from 79% (10 mm) to 83% (4 mm).

Application:
Installing polycarbonate is a simple job, without the risk of breakage. The material is lightweight and is mounted using glass clamps or supplied plastic profiles. This way, proper installation is assured.

Double-walled:
Polycarbonate is double-walled and therefore has a good insulating function. The insulation value differs depending on the thickness of the polycarbonate. The lower the value, the better the insulation. 

Insulation (K) values:

4 mm polycarbonate: 4.2 W/m² K
6 mm polycarbonate: 3.7 W/m² K
10 mm polycarbonate: 2.9 W/m² K

Disadvantages of polycarbonate:

• - Plastic is always more susceptible to weather influences and UV radiation. Under the influence of sunlight, wind and rain, the quality and appearance of polycarbonate are affected over the years. This can lead to complete replacement of the polycarbonate.
• - Condensation of moist air can occur in the channels of the plate.
• - The 'light weight' characteristic can be disadvantageous if the greenhouse is placed in a location where it catches a lot of wind.
  
  

Glass transport and storage

The transport of glass packages and glass boxes requires a lot of attention. It is therefore important that you are well informed about how glass is transported and what is required for its proper storage. We are happy to explain it to you.

What you need to know about glass:

• - Glass is always well packed in cardboard packaging and/or a wooden box.
• - Glass must always be transported and stored upright.
• - Glass is the best seal for your greenhouse, but is also heavy and fragile.
• - Glass is very durable; good resistance to scratches, atmospheric and chemical influences.
• - Glass can have sharp edges, so always wear gloves when handling glass.

How Royal Well provides the transport:

• - Glass boxes are often narrow and must therefore be transported in a stabilized manner, using specially developed trestles.
• - Not every glass box can be transported using a glass trestle, in which case wooden braces are used.
• - Small and medium-sized glass boxes are moved using a pump truck, large glass boxes using a cage monkey.
• - After delivering the glass box, the driver will immediately take the used glass box back with him.

Your responsibility for delivery and storage:

• - Always check your shipment for accuracy and any visible damage.
• - After the receipt check, you sign the shipment for receipt and, if applicable, provide your finding(s).
• - If any damage or breakage is reported upon receipt of delivery, you retain the right to a free repair delivery.
• - Moving a glass box can only be done with the help of a hand truck or pump truck and extra assistance.
• - A glass box must be stabilized after receipt, for example use wooden braces.
• - The glass box can be opened by removing the top of the box.
• - Glass plates must be removed 1 by 1 from the box or packaging and moved to the mounting location.
• - Only start glazing the greenhouse when the entire frame has been fully assembled and you are sure that the glazing can be completed in one go.
