If you have a broken sealed unit they don’t just look unsightly they’re now hugely underperforming. Blown sealed units no longer give you the full benefits of double glazing, the Argon gas will have escaped between the panes of glass creating a thermal barrier between the cold outside and your warm air inside, once the sealed unit has been broken this disappears leaving you with little or no thermal protection.
Solar Control Glass works by deflecting the heat from the sun away from your window, keeping you cooler in summer.
Annealed glass is typically used for most windows (windows cannot be within 800mm from the floor level), Toughened glass is generally used for Front & Back Doors, Full Height Windows, French Doors, Bi Folding Doors and Patio Sliding Doors etc to conform to building regulations.
