Heritage
IN KEEPING WITH TRADITION
When replacing windows and doors in heritage properties in the UK, companies can face multiple challenges from regulation compliance to aesthetics.
The regulations( both local and national) combined with the task of maintaining a look and style that is in keeping with the building’ s tradition is compounded with homeowner’ s demanding the perfect finish.
When installing PVC-u windows and doors in heritage buildings, one of the critical factors is ventilation. The Building Regulations, Approved Document F( means of ventilation) changed in June 2022, thus making it compulsory for companies replacing existing windows and doors, to meet new ventilation requirements.
With installation of mechanical ventilation being expensive, inconvenient and time consuming, the most practical and affordable way to achieve compliance is to install trickle vents to window and door profiles or frames.
In addition, most if not all homeowners are looking for a perfect finish to maintain the traditional aesthetics which makes getting the right ventilation solution a vital choice for any window company operating in the heritage sector.
