The Lean-to conservatory is its universally known name however it can also be known as a Mediterranean conservatory or sometimes a Sunroom. This design is ideal to create a non-imposing, clean looking extension to your property and is often used where not much space is available under the eaves such as on a bungalow.
All Lean-to conservatories are available in our range of Artisan colour finishes and the addition of a bi-folding door or French doors can be a modern enhancement to this popular conservatory design.

The figures shown above are for guide purposes only. Slight variations may occur due to glass specification, time of year, manufacturing tolerance, point of manufacture and type of instrumentation used.


Visible Light Transmittance:

This is the percentage of visible light directly transmitted through the glass.
Solar Factor: This is the percentage of total solar energy (or heat from the sun) able to pass through the glass.
U-Value: This is used to measure internal heat loss during cooler periods. The lower the number, the greater the insulation.
UV Transmission: Sun damaging UV rays are dramatically reduced, allowing greater protection of your furniture and fabrics.

Gable Conservatory Roof Conversion

We can also convert your existing Gable Conservatory to insulate it far more than it currently is. If you feel that your conservatory is too hot in summer or too cold in winter we can make a real difference for you, by adding a space age insulation blanket and installing internal decorative UPVC cladding.  This to prevents against heat in the summer, and provides maximum insulation from cold transfer  in the winter,  our roof insulation this will also reduce unwanted rain and traffic noise se our start to finish installation videos here.
