Glazed Doors for your Orangery
When it comes to selecting doors, whether they are for external or internal use and whether they are to be fitted to business or domestic premises, there are a number of considerations that should be taken into account and a number of options available. Once the customer has decided that they want glazed doors, there are many further choices open to them.
Single glazed doors are the first option. A single glazed door is as the name suggests one that features a single panel of glass. For heating and insulation purposes, it is most likely that the glaze is a panel in an otherwise wood, UPVC or composite door than making up the whole of the door area.
Many people in the past have been unsure of single glazed doors because of the safety issues that are associated with a single panel of glass that can shatter or crack under pressure. Many glaziers have dealt with this issue by developing glass coatings that strengthen the glass and extend its lifespan.
The second option has been, for a long time, the most popular in double glazed doors. Using two sheets of glass with a layer of air between them is the most common way to manufacture windows and doors and the use of double glazing offers a seemingly safer option along with the added insulation provided by the air pocket.
The third option, which is widely available but not as frequently used due to the high costs involved, are triple glazed doors which tellingly use three panes rather than two with air pockets separating each pane.
Whilst it might be assumed that a triple glazed door might be more energy efficient than a double glazed conservatory door, studies have disproved the theory, and surmised that although there is a difference between the amount of heat escaping from a double or triple glazed frame, it is not sufficient enough to justify the cost difference between the two.
The same study, however, found a marked difference between the sound muffling qualities of the two different Glazed Doors and noted “…Installing these units into properties near major roads can increase the value of the home and provide a far nicer and quieter environment for the residents”.
Whenever glazed doors are purchased in the UK, their manufacturer, installation and guarantees are governed by a regulatory body called FENSA. Standing for fenestration self assessment scheme, FENSA is responsible for monitoring and maintaining standards within the glaze industry.
When you deal with an certified FENSA installer, it ensures that all products are manufactured in accordance with building regulations and are safe and efficient for the required use. Without the relevant FENSA certificate it is difficult to sell a property that has had any recent glazing work or that contains glazed doors.
