Again, there is no definitive answer here because it depends on several factors - most prominently, property type and individual budget. Generally, uPVC windows are known for their durable, ultra-efficient, low maintenance and relatively budget-friendly features. Aluminium windows are a common sight in commercial buildings but are fast becoming the material of choice for sleek, modern residential window replacements, including restrictive conservation projects.
Here’s a helpful comparison table for quick reference:
|uPVC windows||Aluminium windows|
|Typically last 25-30 years, exceptionally low maintenance||Can last up to 45 years with minimal maintenance|
|Budget-friendly||Can add considerable value|
|Thicker uPVC frames offer slightly better soundproofing qualities than other materials||Slimmer frames than any other window material|
|Thermally sound A+ rated frames, thanks to innovative 5 - 8 chambered profiles||Thermally sound A rated frames that include innovative 'thermal break' technology.|
|Durable weather-protection; Fade, rot, and salt corrosion resistant||Outstanding weather-protection and natural corrosion resistance; Unaffected by temperature changes; actively resists twisting and warping|
|Environmentally responsible||One of the world's most eco-friendly building materials|
Planning permission doesn't tend to apply for window repairs or minor improvements. Unless any of the following points apply, it's unlikely you'll need to apply for planning permission to replace your windows:
Currently, replacement windows must have a minimum WER rating of band C or a U-value no higher than 1.6 W/m2k.
Generally, safety glazing is required in unobstructed openable areas; at least 0.33 square metres and at least 450mm high and 450mm wide.
Rooms where steam will be produced require higher levels of ventilation, e.g. larger windows or trickle vents.
External windows may need to be fixed shut to limit the risk of fire spread.
Replacement windows can only be reduced to a size a person can safely escape through. It's also good practice to replace first floor windows with escape windows.
