Understated, straightforward, and right for the majority of houses. Multi-point locking secures all four sides of the sash as standard, and the glazing beads clip in from inside so the glass cannot be prised out from the outside. Wind and water tested to the severe classification, so it holds up on exposed elevations. With the right glazing, U-values reach as low as 1.2 W/m²K double glazed and 0.83 W/m²K triple glazed, though the figure depends on the glazing unit and the size of the opening. We have a wide range of casement windows to choose from, with eighteen colours held in stock and a wider range available to order, including woodgrain and matt finishes. Beading can be specified chamfered, scotia or ovolo, and Georgian or astragal bars are available where the house calls for a divided light. Get in touch and we will talk you through what is available. ![Badges](https://mullionandco.com/hs-fs/hubfs/Badges.png?width=300&height=63&name=Badges.png "Badges") [![Central Stack\_Mullion Light](https://mullionandco.com/hubfs/Central%20Stack_Mullion%20Light.svg "Central Stack_Mullion Light")](https://mullionandco.com?hsLang=en) 01642 989 754 · 0191 359 2692 [hello@mullionandco.com](mailto:hello@mullionandco.com)   Based in Middlesbrough.
