Windows from Midland Glass are available in a variety of styles and colours to suite your home and are all made on site at our custom built factory in Derby.
Our casement windows are manufactured using Liniar profile, a 100% lead free PVCu system.
Liniar is one of the most thermally efficient window profiles, and the most technically advanced in the UK.
Liniar window profile contains symmetrical chambers to minimise the transfer of heat from the inside of your home to the outside. This, combined with a range of additional design features and high quality glazing, makes windows from Midlands Glass an energy efficient choice - we can achieve U-values as low as 0.8 W/m2K.
