If you own a listed building you will understand the importance of preserving the character of your building as much as possible. Planning officers share the same philosophy, which means that historically, planning permission requests for replacement windows and doors with double-glazing have mainly been declined.
A modern solution to historical problems
As approved installers of a new type of glass technology called Fineo, we are now able to offer listed homeowners a comprehensive re-glaze, draft seal and paint service which ensures the original aesthetic of their home are maintained in line with local authority guidelines – without the need for planning approval
Fineo’s ultra-thin (6.7mm) profile means it can be easily retrofitted into all timber windows and doors– so the original historical frames are maintained. Because we are replacing the glass within the existing timber frames, you will save months of precious time and thousands of pounds by preventing the need to go through the lengthy application process.
Turn your glass into radiators
Compared to single glazing, Fineo provides substantial improvements to energy efficiency. A double- glazed vacuum insulated Fineo glass unit boasts thermal efficiencies better than a traditional 36mm triple glazed unit but is no thicker than single glazing.
Width of single glazing | warmth of triple glazing
Fineo will keep heat in and cold out no matter what the temperature is outside. For example, the table below shows that if the temperature outside is -10°C and the temperature inside your home is 20°C, then your old single-glazed windows will only retain -2.75°C opposed to the 17.3°C retained by Fineo glass.
Reduces your carbon footprint
Historically, double-glazing requests submitted by listed property owners have been denied by local councils which has deemed listed buildings to be incredibly inefficient in terms of insulation. Many period properties will house old heating systems which, when coupled with inefficient glazing, results in masses of wasted energy. Fineo’s revolutionary double-glazed, energy efficient units will keep older properties warmer and quieter plus, they are lead free and 100% recyclable.
Zero inert gases
Fineo is vacuum sealed glazing, which means that unlike traditional double-glazing (that has a gas filled space in between two sheets of glass), all the air between the glass sheets is completely removed. The vacuum that is created means it is almost impossible for heat to transfer through it which is what makes it so energy efficient. It also means that unlike double-glazing that needs a noble gas inside of it (which has to be mined, extracted, bottled up, and shipped all over the world), Fineo is an extremely low carbon product to manufacture.
