SILLS

 

A sill is an element that receives a substantial amount of water due to its position beneath a watertight surface (frame and glass). All of the rainwater that falls on this surface has to be evacuated via the sill. The purpose of the sill is to keep the water out of the underlying masonry.
 

As a minimum requirement the sill should therefore:
- have a sufficient external slope (min. 5%) to ensure that the water runs off it easily
- protrude at least 5 cm beyond the facade and have a drip groove to create a barrier against the water
- be integrated laterally into the framework to a depth of at least 5 cm in order to prevent water seepage between the sill and the masonry
 

The ideal sill should have:
- a back dam to ensure effective waterproofing
- an end dam at each side to ensure that it is well integrated into the masonry, and to prevent the water being driven against the masonry
- if the sill is made up of two pieces the joint between the two elements should be made waterproof (e.g. using a silicone kit), or a drip stone should be placed under the joint

CAPSTONES

 

The purpose of a wall cap (capstone) is to prevent the masonry from becoming overly damp, by, on the one hand, preventing the rainwater from penetrating along the upper side of the wall, and, on the other hand, by conducting the maximum amount of water towards the exterior.
 

As a minimum requirement the capstone should therefore:
- have a sufficient external slope (min. 5%) to ensure that the water runs off it easily
- protrude sufficiently beyond the plane of the masonry and have a drip groove to create a barrier against the water
- the joints between the capstones must be waterproof or must be equipped with a system which will prevent the water from penetrating the joints (e.g. a drip stone)
