With optimal lining details you can increase the daylight that reaches your attic’s interior surfaces by more than 20%*
For in reach applications, the top lining should be horizontal and the bottom vertical to allow the maximum amount of daylight into the room.
Top and bottom linings at right angles to the window should be avoided. Not only does this impair views and light, it can also result in cold areas at the bottom of the window, allowing condensation to occur.
Note that the colour of the lining also has an influence on the amount of light reflected into the room - the lighter the colour, the more daylight is reflected.

Rule of thumb: 45°
For out-of-reach applications, no matter what the roof pitch, it is recommended to have a minimum 45° splay to the top and bottom of the lining.
For flat roof windows it is also optimal to have a splay to all sides of the lining. Where this is not possible it is best to splay the edges that direct the light deeper into the floor plan.
Get creative with integration
Linings can also be incorporated into window sills that act as shelving, built-in seats or daybeds. This is a great way to create a standout feature in a room and differentiate your spaces from competitors.
