Homesealed's industry leading sash horn windows provide the traditional style of yesteryear combined with 21st century materials, offering superior performance and functionality.


Sash horn windows are a natural fit for the sandstone tenements and Victorian terraces found across Glasgow, Edinburgh and Central Scotland.
They keep the classic box-sash appearance that suits period properties and conservation areas, without asking you to compromise on performance.
Built to complement our casement window range, a sash horn window looks like a traditional sliding sash but seals and performs like a modern casement, giving you the best of both worlds.
That matters here more than most places, since Scottish wind and driving rain will find any weak point in an old frame within a single winter.
Every sash horn window uses a high-security shoot bolt locking system, giving you strong protection against break-ins alongside the weather-tight seal.
You can also add Georgian bars for a more individual, period-appropriate finish that suits Glasgow's West End tenements or Edinburgh's New Town properties just as well as a modern semi.
