Plastic double glazing and aluminium are both highly resilient to the elements, revered for their energy efficiency ratings and come in a variety of different styles to suit the exact specifications of your home. Both materials are also durable and require minimal maintenance requirements, making them a popular choice with homeowners.
UPVC double glazing limits the transfer of heat or cold which reduces your need for expensive heating or cooling and can help to minimise the build-up of condensation in your windows, doors & conservatories. Moisture on a warm surface forms droplets of water known as condensation which can be extremely damaging to your home. When these droplets form on a window they are unable to evaporate due to the low temperature of the air and can encourage mildew and mould. UPVC double glazing is more resistant to moisture than wood or aluminium which helps it maintain its durability and avoid damage from condensation.
Maximizing Energy Efficiency: The Advantages of Plastic Double Glazing
The gap between the panes of a UPVC double-glazed window is filled with an inert gas (usually Argon) which slows the transfer of heat. When cold air is transferred between two panes of glass, the gaps on either side of the frame act as a thermal bridge and transfer some of the cold from the outside to the inside of the window. Argon has a 34% reduced rate of conduction than air meaning less heat is lost from the inside to the outside of the window.
The spacer bars on the edge of a double-glazed unit are made from warm edge technology which is blended from stainless steel and polypropylene. The warm edge spacer bars are a much better conductor of warmth than old aluminium and significantly reduce heat loss around the edges of the sealed unit.
