Conservatories, Sunrooms - Some typical specifications / base details

A DISCLAIMER: Our construction guide and these sectional drawings are not a complete instruction manual. Please note we cannot accept responsibility for erroneous constructions based on this guide.

ANOTHER SPECIAL NOTE: These sectional drawings are just typical sections - you or your builder may use different sections depending on site circumstances.


With example 1 we have a fairly typical section for the construction of a base and dwarf wall. This assumes that the site is reasonably level and without any major difficulties. As an example of a variation on the above - note that many suppliers prefer to "sit" the inside of the conservatory frame flush with the inside of the external course of brickwork. In our example the frame has been fitted slightly forward of the inside edge of the external course of brickwork in order to facilitate an easier fixing for the internal window board. Either method is OK in our opinion.

We again have a fairly typical example based on a site without many difficulties. As previous you may find that your supplier will fit the frame flush with the inside edge of the foundation. Also your builder may create a brick faced base rather than concrete faced base. In our example the conservatory frame rests on top of a damp proof membrane. This is often used when using timber frames. However with PVCu frames it is more likely your builder will lay the PVCu frames directly down on foundation. (PVCu is after all a damp proof material). The usual finish then is to "lap" the membrane that's under the concrete floor up against the frame on the inside.


This shows a suspended floor detail often used where there is a significant difference in levels between the ground level and the finished floor level (FFL) of the conservatory. Note an air brick should be inserted at front.


We have a good example of one way to overcome a large variation between levels. You should remember with examples like this to allow for brick steps (plus other landscaping) in order to safely "step down" from your conservatory to the ground level.
