Bar Capping

Adding Bar Capping to your greenhouse will provide a much stronger hold for the greenhouse glazing but it also adds an attractive decorative finish.

The rubber fin on the bar capping will help protect your greenhouse against heavy rainfall because it adds a better water seal between the frame and the glass.

Bar Capping is used along with greenhouse spring clips and this will add a double protection for your glazing against extreme weather conditions which makes adding capping to your greenhouse an ideal solution when you live in more exposed areas.

Greenhouse Glazing.

What type of glazing material is the right choice for your modern greenhouse ?

Most greenhouse manufacturers offer three types of greenhouse glazing these are horticultural glass, toughened glass and polycarbonate glazing, each one is different and knowing a bit about each glazing type will help you decide which is the right glazing needed.

Generally horticultural glass comes in small sheets, either 2′ x 2′ or 2′ x 18″ and when it is broken it will break into dangerous jagged pieces which can cause serious harm.

Toughened glass sheets is usually the same size horticultural glass or more popularly in full-length sheets, toughened glass will ranging from the lower end which is just basic toughened glass and is the cheapest option but will not necessarily break into small pieces like the top quality toughened safety glass.

When you break toughened safety glass it will breaks similar to a car windscreen into very small pieces and is relatively harmless as there are no large jagged pieces.

Polycarbonate although not see through comes in full-length sheets and depending on the thickness can be quite flexible, not only is it lightweight polycarbonate helps to prevent scorching of the plants but if you live in a very windy area it is more likely to blow out.
The preferred glazing option for many greenhouse Buyers is toughened safety glass which usually has the British standard symbol stamped on it.

Greenhouse Safety Glass.

When choosing glass for your greenhouse there are many considerations to think about personally if you have young children or family pets around i would choose toughened safety glass.

Toughened safety glass has a special feature apart from being a very strong glass if it does ever get broken you will not get broken shards of glass but a granular shape which is small in size and shape.

This granular glass is much safer and is less likely to cause any injury to yourself, family members or any animals that maybe around.

Greenhouse Glazing Clips.

Different makes of greenhouses use different types of clips to hold a glass in, the most common being the wire ‘W’ clips which have now been around for many years,these are now being superseded by either spring clips or bar capping, bar capping takes the place of any other clip and covers the outer part of the glazing bar holding the glass in on either side by means of a screw being screwed through the glazing clip into a recess in the glazing bar, this not only forms a very secure way holding the glass in but is very attractive and can be colour coded to the colour of the greenhouse, e.g. white for a natural aluminium or a colour to match the colour of the greenhouse.

 

Types of greenhouse glazing.

There are three main glazing materials used in the modern greenhouse these being horticultural glass, toughened glass and polycarbonate glazing. The difference between these materials are horticultural glass comes in small sheets, either 2′ x 2′ or 2′ x 18″ and if broken breaks into dangerous jagged pieces. Toughened glass on the other hand can be obtained in either smaller sheets the same size horticultural glass or more popularly in full-length sheets, toughened glass also comes in three different qualities ranging from the lower end which is just basically toughened glass and is the cheapest option but will not necessarily break into small pieces like the toughened safety glass which is of a higher quality, if you accidentally break the toughened safety glass it will break similar to a car windscreen into very small pieces and is relatively harmless the polycarbonate on the other hand comes in full-length sheets and is quite flexible depending on the thickness, the benefits of polycarbonate are mainly is lightweight and helps to prevent scorching of the plants, some of the disadvantages are that if you live in a very windy area it is more likely to blow out and you cannot see clearly through it.
For my part I prefer toughened safety glass which usually has the British standard symbol stamped on it, unfortunately some manufacturers who quite genuinely produced toughened safety glass do not use the symbol and this sometimes can cause confusion with customers, my advice is to only deal with a reptile dealer whom you can trust to tell you the truth about the glass they are selling in their greenhouses.
