SLIM GLAZE HERITAGE UNITS – DOUBLE GLAZED UNITS FOR TRADITIONAL SASH WINDOWS

Slim Glaze Heritage by Rathmines Glass

Our Slim Glaze Heritage double glazed units are the most modern double glazed units on the market today in Ireland. Specifically designed to fit into narrow sash window frames. This newly developed system has very slim double glazing making it suitable for the traditional timber widows of period houses.


The majority of these period houses in Dublin and throughout Ireland are under protective orders. This means that the owners are not allowed to alter the exterior of the building. These older buildings are usually fitted with single glazed windows which have very poor heat retention abilities and are not energy efficient. This leaves many homeowners living in cold and draughty homes.
Our Dublin manufactured Slim Glaze Heritage unit is the solution to all of these problems.
Slim Glaze Heritage units are designed to fit into the existing timber frames so you can now upgrade your home's windows without changing its appearance at all. A joiner / carpenter will route out the timber frames and remove the old single glazed windowpanes. Our window technicians are then able to install these super thin double glazed units. Either at our premise in Rathmines, or onsite at your home or business.


Due to the very narrow sight line, due to the 4mm Superspacer warm edge bar. From the outside of the building, you will not be able to tell that new windows have been installed. The unique aesthetic and charm of your Georgian, Victorian, or period house will remain completely unaltered. You will definitely notice a change inside your home. With massively improved het retention.

Our Slim Glaze Heritage units can allow for up to 80% heat retention compared to 30% retained by the single glazed windows. They also reduce the level of street noise entering your home as well as minimises window condensation and eliminating any window draughts.
