ThermaCore™ Air
Lightweight, Everyday Comfort
The ThermaCore Air range is built using our high-grade insulated composite material, engineered for stability, warmth retention, and long-term durability in the British climate.
It features our popular 64mm blade size, delivering a crisp modern look, smooth light control, and reliable everyday insulation.
To further boost performance, every Air shutter is installed within our ThermaCore external frame system, which includes a thermal neoprene draft excluder. This creates a tight perimeter seal, reducing cold spots and stopping heat escaping around the edges of the window.

ThermaCore™ Plus
Advanced Insulation & Balanced Performance
The ThermaCore Plus range is our most popular option — the perfect balance of style, insulation, and everyday performance. Built from our premium insulated composite material, the Plus range delivers enhanced warmth retention, a more refined finish, and a stronger overall feel compared to entry-level shutters.
Using a 74mm blade, this range offers wider louvres for a cleaner, more elegant look while allowing more natural light into the room when open. When closed, the broader blades and insulated core work together to significantly reduce heat loss.
Like all our products, the Plus range includes the full ThermaCore frame system with a thermal neoprene draft excluder, creating a tight perimeter seal that stops cold air creeping around the frame and boosts overall thermal performance.

ThermaCore™ Max
Ultimate Warmth, Luxury Finish
The ThermaCore Max range is the highest-performing shutter system we offer. Built from our densest insulated composite material, it delivers exceptional thermal efficiency, a premium weighted feel, and a bold, modern finish that stands out in any room.
This range features our impressive 89mm blade, available in two formats:
UbMax Blade – Fully Sealed Closed System (Premium Option)
The UbMax blade is our top-tier, fully-sealed system designed for maximum insulation.
When closed, the blade forms a tight, highly efficient seal, dramatically reducing heat loss, blocking drafts, and delivering the strongest thermal performance in the entire ThermaShutter lineup.
This is the go-to choice for customers wanting the warmest, most efficient shutter system possible.
Standard 89mm Blade – Contemporary, Open-View Design
A classic wide-louvre shutter offering excellent everyday insulation paired with a modern, sleek look.
Perfect for customers who want a premium style and strong performance without needing the fully sealed UbMax upgrade.
As with all our shutters, the Max range is installed within our ThermaCore external frame system, complete with our thermal neoprene draft excluder. This creates a tight perimeter seal around the frame, removing cold spots and improving overall room comfort.
Who It’s For
Homeowners who want the ultimate in warmth, style, and long-term performance.
If you want the most premium shutter system — especially with the UbMax sealed blade — the ThermaCore Max range delivers uncompromising comfort and modern design.
