Cotswold Casements fitted windows on this luxurious, contemporary property in Berkshire around 10 years ago, and recently the customer asked us to return to fit steel doors too. We used W20 internal and external screens painted in dark grey (RAL 9004) to match the existing windows and create a cohesive look throughout the property. The internal screens are single glazed, but the external doors have double glazing to keep warmth in and noise out.
