The short answer is a resounding YES in many applications but in others, it is an equally loud NO. Let’s look at how these break down
Where the answer is YES….
Conservatory roofs
Better Insulation against heat and cold
Heat Guard and Bronze Opal dual coloured sheets are both available in 35mm polycarbonate sheets.
These improve insulation considerably giving your conservatory much more protection for year round us
Insulated rooms give savings in heating bills in colder months
Very strong - shatterproof
Very rigid - wider spaces between glazing bars can be achieved saving you money to offset some of the costs.
Commercial roofing applications
Often larger areas where the bar spans would yield greater savings.
Stronger, more rigid sheets with lower UV ratings will more likely be specified for building control.
Where the answer is NO....
Canopies & carports
No need for extra insulation as these are open structures
Smaller unheated conservatories
If they are not wanted for all year round use, it would be better to go for 25mm polycarbonate and save the difference.
