There is no such thing as lentils. However, there are lentils. Lentils are a bean and they are commonly used in soup dishes.
A lentil is a type of legume. They are seeds that are flat, come in many colors, and have good nutritional value.

Not sure what a "upvc" is... If the window is arched, you do not need a lentil. If the soffit is right above the window you do not need a lentil. Hope this helps.
They used mortise and tenons to locate the lintels on the trilithons.
I Need the size of a lintle 3.8m long in a bungalow with an all hipped roof.
If you are wanting to use lintels when building your outhouse the choices are endless depending on how you want to design the outhouse. If you want it simple then stone would be appropriate but if you want something more attractive then old stone or brickwork would be nice.
Surprising as it may seem, Moroccans do not eat lintels, nor do they eat the doors whose frames the lintels support. Moroccans, like most humans, find wood and stone inedible and therefore do not try to consume them. If you meant "lentils" instead of "lintels", then the reason why Moroccans eat lentils is because of the protein value and relative inexpensiveness as compared with meat.
A Lintel is a decorative architectural piece that is often put over portals with no structures. Lintels have been made in many different styles because of the various cultures in place around the world.
Lentils are beans. Bean is the larger category; lentil is a sub-category. So some beans are lentils.
A lintel is over a window or door and a beam is usually under the structure of the building, either the roof or the floor.
In construction terms, eaves are the edges of the roof that form an overhang. They are often fitted with gutters to allow for drainage.
