Quartzite Slabs
Quartzite is a naturally occurring stone that forms underground when sandstone gets altered inside of the earth due to exposure to extreme pressure and high temperatures. Typically, quartzite is mined at a quarry and then cut into slabs to be turned into countertops.

Benefits of a Marble Window Sill
Choosing a marble window sill for your renovation is a valuable addition to any home. If you are renovating and putting in new windows, you may be wondering what material to use for your interior and exterior window sills.
Marble window sills are not only timeless in style, they are aesthetically stunning and durable. Marble is naturally long-lasting, not easy chipped and are not damaged by sunlight making it ideal for both interior and exterior sills.

Benefits of a Granite Window Sill
Granite is an incredibly hard material, with a long wearing nature that will not easily break or damage. Another advantage of using granite, is that the stone is UV resistant, so you can rest assured knowing your window sill won’t fade in colour or damage from sunlight.

Installing a quartz window sill is both a cost-effective and a practical choice for your home. Quartz is an engineered stone which is typically more affordable than marble and granite. There are even quartz colours that mimic the look of marble, so if you are looking to save on costs, quartz might be the answer you are looking for.
Available in a huge range of colours and patterns, it can be matched with your kitchen worktop to create a cohesive look in your kitchen.
Quartz window sills are non-porous, stain-resistant, durable and easy to maintain. They are naturally resistant to mould and mildew, a great asset for your home.
Enhance Both Form And Function
Our window sills are more than just a design element—they’re built to last. Designed to protect your walls and frame while adding a stylish touch, our sills are both practical and aesthetically pleasing. With a range of materials and finishes to choose from, we help you achieve the perfect look and durability for your space.
Suggested Surface Finishing
Polished
Provides a glossy, sleek look, suitable for marble and granite, enhancing the stone's natural colors and patterns.
Honed
Offers a matte finish that is less prone to showing scratches, suitable for all stone types.
Flamed or Brushed
Good for increasing slip resistance and hiding wear, especially on slate and limestone.
