Insulated Garages · the insulated line
100mm of high-performance insulation in the walls and roof, finished in deep architectural anthracite. Warm in winter, cool in summer, quiet in the rain — the difference between somewhere you park the car and somewhere you would happily set up an office, a gym or a home for a car you care about.
Free to design · ~5 minutes · fixed price online — no site visit needed.A standard metal garage keeps the weather off. With 100mm insulated panels you get a sealed, dry, temperature-stable space — no condensation on your tools, no summer oven, no winter freeze. The closest thing to a brick extension without the brick-extension price or the months of building work.

About planning
Insulated garages are taller than basic metal ones. Within 2 m of a boundary the permitted-development height cap is 2.5 m, so most sizes will need a planning application when sited close to a fence or wall. Set further back, our apex models are typically within the 4 m PD limit. We assess your plot — heights, roof type and distance to boundaries — and tell you clearly what's required before you commit. It is a routine step we handle with you. Read our planning guide →
Build it up to suit
Each upgrade is a fixed price. Prices shown for Insulated 24 / 30 / 36 where size-based.

Our recommendation
Our most balanced insulated configuration — the comfort of climate control over a true showroom floor.
| Insulated 30 | £31,950 |
|---|---|
| Showroom Finish Collection | £2,495 |
| Climate Comfort Collection | £4,495 |
| Total (inc. VAT, delivery & install) | £38,940 |

Start from this configurationWhat's included / what's separate
Included: the building, insulated door, side door, window, guttering, delivery, installation, VAT, and the VeltHaven 10-Year Structural Warranty (2 years full warranty + structural cover to year 10).
Quoted separately after a site assessment: the level base/slab it sits on. Electrical packages include connection and certification on a standard connection; only non-standard conditions (trenching, long runs, a board upgrade) are quoted on top — always before you commit.

How it's built
Every wall and roof is a single insulated panel — two steel skins bonded to a rigid PIR foam core and locked together with a concealed tongue-and-groove joint. 100 mm PIR core · steel skin both sides · wall U-value 0.23 W/m²K.



Engineered to last
Every wall and roof is a steel-skinned insulated sandwich panel — the same panel system used in modern commercial buildings, finished to a premium standard.
| Insulation core | Rigid polyisocyanurate (PIR) foam |
|---|---|
| Thermal conductivity | λ = 0.022 W/m·K |
| Standard wall thickness | 100 mm |
| U-value (100 mm wall) | 0.23 W/m²K |
| Available thicknesses | 60 · 80 · 100 · 120 · 140 mm |
| Total panel width | 1,050 mm |
| External cladding profiles | Linear · Microprofiled · Ribbed · Grooved · Flat |
| Standard external colours | 10 RAL finishes + 2 woodgrain options |
| Fire reaction | B-s1, d0 |
| Fire resistance (100 mm) | EI 15 |
| Fire propagation | NRO (non-fire-propagating) |
| Certification | EN 14509, CE-marked |
| Insulation core | Rigid polyisocyanurate (PIR) foam |

| Standard roof thickness | 80/120 mm (composite) |
| U-value (80/120 mm roof) | 0.27 W/m²K |
| External roof profile | Trapezoidal |

| Fire resistance | REI 30 / RE 120 |
| External fire action | BROOF (fire-resistant roofing) |
| Certification | EN 14509, CE-marked |
PIR foam has one of the lowest thermal conductivities of any insulation material — significantly better than standard mineral wool. That means a thinner wall delivers the same warmth, keeping your garage dry, temperature-stable, and free from condensation year-round. The steel-skinned sandwich panel also resists rodents, mould, and mechanical impact in a way that brick or timber simply cannot. Every panel is independently tested and carries a CE mark under EN 14509.
