Wide-Span Internal Shutters
Built to withstand the toughest environments. Here is an inside look at a multi-shutter installation, providing secure, wide-span access for this large-scale storage building in Houghton.
Insulated garage roller doors
Upgrade to a premium, foam-filled insulated roller door that locks the heat in, blocks out the street noise, and secures your property—all at the touch of a button.
Invisible Insulation. Incredible Results.
If your garage is attached to your house, or if you have a room directly above it, a standard single-skin steel door is acting like a giant open window—leaking your expensive heating straight into the street.
Why insulated garage doors
We engineer our doors differently so you can reclaim that space.
- Twin-Walled Thermal Protection: Every single slat is constructed from twin-walled aluminium, tightly packed with high-density, CFC-free insulating foam. Because the foam is completely sealed inside the metal, you will never see it, never have to maintain it, and it will never degrade. Just a beautiful, sleek metal finish on the outside, and a powerful thermal blanket on the inside.
- Acoustic Sound Dampening: Live on a busy road? The dense foam core absorbs sound waves, dramatically reducing street noise. Even better, because the slats are thick and tightly interlocked, you won't have to listen to your garage door loudly rattling in the wind during a heavy winter storm.
- Reclaim Your Space: How it works for you: By stabilizing the temperature and keeping the freezing draughts out, your garage stops being just a cold storage room. It becomes a comfortable, year-round space—perfect for a home gym, a utility room, a workshop, or a safe playroom.
Product options
The first decision is what you want to be able to see — and what you want people outside to be able to see — when the shutter is closed. That determines which curtain type is right for your premises.
55 mm slat height
Solid insulation for a standard garage
The 55mm foam-filled profile is the right choice if your garage is a standard single size and your main goals are keeping the cold and noise at a reasonable level without needing maximum thermal performance.
The insulation is genuine and effective — this isn't a token gesture. It's a properly foam-filled aluminium door that will feel noticeably warmer and quieter than whatever you've got now.
What you get:
- PA55 aluminium profile — CFC-free foam core, sealed inside both aluminium skins
- Thermal and acoustic insulation as standard
- Brush pile seals in the guide channels — reduces draughts at the sides
- Heavy-duty rubber weather seal at the bottom
- Maximum width: 2400mm
- Electric operation included — remote control with 2 handsets
- 30+ colour options
- 5-year warranty
Best for: Standard single garages, limited headroom above the opening.
77mm slat height
Stronger, better insulated, and essential for wider openings
The 77mm profile has nearly 40% more foam fill than the 55mm. That translates directly into better thermal performance, more acoustic absorption — 22dB of noise reduction — and a door that’s stronger and feels substantially more solid in operation. Open and close a 77mm door and it has a weight and deliberateness to it that thinner doors don't.
What you get:
- PA77 aluminium profile — CFC-free foam core, sealed inside both aluminium skins
- Enhanced thermal insulation — measurable difference in garage temperature vs 55mm
- 22dB acoustic reduction — road noise becomes background hum
- Brush pile seals in the guide channels
- Heavy-duty rubber weather seal at the bottom
- Maximum width: 3,000mm (bracket mount), up to 6,500mm (box configuration)
- Electric operation included — remote control with 2 handsets
- 30+ colour options including woodgrain foil finishes
- 5-year warranty
Best for: Double garages, converted garage spaces, workshops, home gyms, any situation where the thermal, acoustic performance and extra security genuinely matters to how you use the space.

Frequently Asked Questions

It depends on the starting point and how airtight your garage is overall — the door is one part of the thermal envelope, not the only one. That said, the difference between an uninsulated single-skin metal door and a foam-filled 77mm roller door in an enclosed garage is genuinely significant. Garages that were unusable in winter regularly become comfortable workshop or gym spaces with just the door upgrade. If you also insulate the walls and ceiling, the door’s contribution compounds further.
No — and this is worth being clear about. The foam is permanently bonded inside the aluminium during manufacture. It’s not exposed to UV, moisture, or physical wear. There’s no mechanism by which it degrades independently of the door itself. The insulation you get on day one is the insulation you have in year fifteen.
Almost always yes. Retrofit insulation panels or board reduce your headroom, are visible from inside, don’t seal at the edges the way an integrated foam-fill does, and add complexity to the door’s operation. An insulated roller door is cleaner, more effective, lower maintenance, and when you factor in the full picture, usually better value over time.
Yes, significantly. Condensation forms when warm, moist air hits a cold surface. A non-insulated metal door is exactly that surface in winter, the temperature differential causes moisture to condense on it and run down the inside. By keeping the inner surface of the door closer to the ambient temperature of the garage, an insulated door dramatically reduces condensation. This matters particularly for tools, bikes, and anything else stored in the garage that doesn’t respond well to repeated damp cycles.
Yes, the foam absorbs sound in both directions. External noise (traffic, wind, rain) is reduced entering the garage. Internal noise (power tools, music, a drum kit your family is very patient about) is partially contained. It won’t soundproof the space completely, but 22dB of reduction is meaningful in both directions.
A non-insulated roller shutter is a single skin of galvanised steel. It’s extremely strong and appropriate for commercial and industrial applications, but it has no meaningful thermal or acoustic performance. Our domestic insulated doors use double-skinned aluminium profiles with foam fill — they’re lighter, better looking, thermally effective, and acoustically rated. Different products for different needs.
In almost all cases, no. Replacing an existing garage door — including changing the type — is permitted development. Listed buildings and conservation areas are the exception; check with your local planning authority if either applies to you.
