Inner PVC sills
Inner PVC sills are extremely user-friendly since they are very resistant to all mechanic and atmospheric influences. They are simple to maintain and clean. You can choose between white or marble imitation sills.
The standard width of inner sills is up to 25cm. Depending on the window installed, you can also choose wider or narrower sills. The maximum length of one-piece sill is 600cm. Dry or wet installation method is possible.
Inner marble sills
Inner marble sills are a common choice since they have a pleasant decorative appearance. As a natural material, marble is extremely sensitive to moisture, which is why we do not recommend it for outer sills. Marble sills can be installed using the dry or wet installation method.
The maximum length depends on the type and thickness of the sill and measures from 250cm to 300cm. You can also choose marble sills if your windows are of irregular shapes. You can choose between four different thicknesses.


Inner granite sills
Unlike marble, inner window sills made of granite are grainier and harder, which is why they are also more resistant to weather conditions and mechanical shocks.
The maximum length depends on the type and thickness of the sill and measures from 250cm to 300cm. Dry or wet installation is possible, as well as the provision of irregular shapes (semicircles, trapezes, etc.). You can choose between different types of thicknesses, i.e. 20mm or 30mm.
Inner window sills made of artificial stone
Inner window sills made of artificial stone are prepared using a special technological procedure from crystal rocks bound together by resin.
Due to this manufacturing process, they guarantee superior quality. They have a smooth and glossy surface and because they are not porous, they do not absorb water.
You can easily clean them with a damp cloth since they are resistant to all weather conditions, acids, lyes, salts and UV-rays. Dry or wet installation method is possible.
The maximum length of a one-piece sill is 2.95m. The sills are available with different patterns and can be 2cm or 3cm thick; regardless of the thickness, they will fit your windows perfectly.



Inner window sills made of HPL
Inner window sills made of HPL are a suitable option when you are glazing a building with extremely wide walls, which are a characteristic feature of older buildings. HPL window sills are made of processed chipboard with PVC end profiles and are waterproof.
In terms of their properties and maintenance methods, they are very similar to inner PVC sills. You can choose between white or marble imitation sills. The maximum width of a sill is 50cm (20mm thickness), while the available length is either 410cm or 530cm (one-piece sill). Dry or wet installation method is possible.
The team came a few minutes before the agreed time and carried out its work quickly and correctly. After they left, the work site was clean and tidy. We only had to wipe away the dust. Very commendable work.
From the moment that I sent my inquiry until the final execution, my experience with MIK was excellent right until the end.
This was a wonderful team. If and when I deal with MIK again, I would like to see the same team of installers.
Everything went as I expected, so I am now recommending MIK products to all my friends who are thinking about renovating their homes.
