How do I know what depth I need?
This is a question we can help with, generally speaking if you have a wall depth of say 350mm, it would depend on where the window is sitting within the opening. For example: if the front edge of the window is sitting 150mm from the external face. You may have battens externally and cladding on top of the battens (30mm in total).
You would add the 150mm, plus the 30mm – however, we require a 30mm minimum overhang to allow the water to drain away from the face of the building. We also have 8mm rebate on the sill of the window for the external window sill to be fixed too.
So what size do we need?
- 8mm sill rebate
- 150mm from externall wall
- 30mm of batten/cladding
- 30mm overhang
Total window sill depth required is 8+150+30+30 = 218mm – this means we need to order the window sill at 225mm depth.
** Please note that there is a minimum order quantity, this must be in excess of 10 window cills, a small order charge and small paint charge may be incurred and import fees will need to be paid **
Gutmann window sill are supplied with a number of different end caps, dependant on the type of finish you are using and the type of build. For example, a rendered or cladded house will require a different type of end cap from a house where the window sits between the brick opening.
The following end caps are available, Ecowin use as standard B254 or B256
| B254 | B256 | B2504 | B2506 |

Not every window sill is going to be straight, you may need to go around a corner, or you may have a little jut out and the cill needs to go around this detail. We can supply different shapes, designs and custom sill when required. Some of the special shapes available can be viewed below.
Water-tight window sill connection between window and window sill – solution based on a reliable process.
The GUTMANN DELTA drainage module offers a simple and reliable solution to the problems that often occur in corner areas due to non-water-tight structure connection seams. The new system promises to make water penetration due to unsealed work holes, improperly installed 
plastering strips or rolling shutter rails, and other unsealed connection joints a thing of the past.
No advance planning is required to install the component, which matches the GUTMANN GS 40/GS 25 window sill system. It is simply attached to the facing frame on the outside of the window. Installed below the window, it reliably channels any moisture that penetrates the construction to the outside, thus preventing costly structural damage.
