Why we’re different
Our ThermaCore™ insulated composite system is engineered to outperform standard shutters and cheap imports in every way. From the blade design to the frame seal, every part of a ThermaShutter is built to keep your home warmer, quieter, and more comfortable.
Built Heavier. Built Better.
ThermaCore shutters are 77% heavier than imported alternatives.
That extra weight isn’t bulk — it’s solid insulated construction, giving you:
A strong, premium feel the moment you touch them
Panels that don’t twist, rattle, or flex like lightweight imports
A denser core with noticeably better insulation
Far greater durability and lifespan
You can literally feel the difference in quality.
ThermaCore Blade Technology
Our insulated composite blades deliver:
Up to 40% better heat retention than MDF or wooden shutters
Zero twisting, bowing, fading, or cracking
Full moisture resistance – perfect for kitchens and bathrooms
Independently verified thermal performance
A thicker, high-strength construction designed for UK homes
These aren’t decorative shutters — they’re engineered thermal systems.
ThermaCore Frame System
Complete Perimeter Seal
Heat doesn’t only escape through the glass — it travels through the surrounding structure.
That’s why every ThermaShutter includes our upgraded ThermaCore external frame fitted with a thermal neoprene draft excluder.
This engineered seal:
Blocks cold drafts
Stops warm air leaking around the frame
Prevents cold bridging from the superstructure into the shutter frame
Reduces cold spots and heat loss
Increases overall room comfort
With the blade insulation and the sealed frame working together, you get a complete thermal system, not just a shutter.
Robust, Serviceable Components
Imported shutters often use sealed or enclosed mechanisms that can’t be repaired — and parts are rarely available.
Our ThermaCore system is built using robust, fully serviceable components, meaning:
