The Paper Hall – Bradford
Originally built in 1643, this Grade 1 listed building was initially intended as a private dwelling. During the English Civil war which ended in 1651 many of the surrounding buildings were destroyed; however, the Paper Hall was able to stand the test of time.
Granada Secondary Glazing was tasked with reducing the buildings carbon footprint by preventing heat escaping through the original single glazed steel windows. Large amounts of noise and heat loss are a common problem for historic buildings with single glazing.
Single glazed steel windows offer minimal thermal insulation and usually have a U-value of 5.7 W/m2K. The installation of secondary glazing acts as a second barrier preventing heat escaping, it can drastically improve thermal insulation leading to decreased energy consumption.
To decrease heat loss, Granada Glazing advised that the secondary glazing was installed with low-E glass. Low E glass has been specifically designed to reflect heat back into the room and can achieve a U-value of 1.87 W/m2K.
To complement the aesthetics of the building Granada’s horizontal sliders were powder coated in RAL 9005 and was installed within the original stone reveals.
