Conservatory and Orangery designs vary enormously, from conventional PVC frames to bespoke timber designs with large amounts of glass. Both forms of structure typically incorporate combustible materials (wood or PVC) that need to be kept a safe distance from a wood burner.
Positioning the stove
Stoves that stand in front of a timber or PVC structure will need to meet minimum clearances as set by the manufacturer. They are commonly around 450mm from the side/rear of the stove. A stove that protrudes 450mm into the room however is often intrusive and unattractive.
When a stove is incorporated at the design stage it is advisable for a section of the structure to be masonry or for stove to be situated in front of the adjoining house wall, where there is one.
Where a masonry back drop is not available, additional measures are required to accommodate the stove nearer the PVC or timber frame.
There are now a number of stoves available with ‘convection’ panels or heat shields. These reduce the distance to a combustible material enormously, sometimes to less than 100mm.
Where a stove is positioned in front of a low wall, it is also advisable to replace the timber section of windowsill behind the stove with a non combustible material such as slate. Slate can be cut to size and the edge rounded in line with the windowsill.
Accommodating the chimney
In almost all cases it will be necessary to use a twin wall chimney system. These are double insulted and require only 50-60mm clearance to a combustible material.
Twin wall chimneys can be powered coated to the match the stove or indeed any colour required.
Where they need to exit the conservatory or orangery, it is possible to create a PVC panel in place of the glass through which the chimney can be run. There are other methods too, such as cutting out a round section from the Perspex roof panel.
