At Bereco we don’t offer a tilt facility. This style of window usually comes with unsightly and non-compressing brush seals that can affect weather performance. However, our cords and weights option is available with an easy clean system that allows the bottom sash to open inwards side hung.
Even though we can offer this, both our hardwood and redwood timbers have the same warranty and are engineered from defect-free timber that is preservative-treated and fully factory finished. At Bereco every individual timber element of our windows is treated with preservative using the most technologically advanced coating systems from Teknos, which is why we can offer our 30-year warranty against rot and fungal decay.
No you don’t, it’s completely up to you. But if you do want them we have seven different styles to choose from.
