Comparison
Liniar vs VEKA
A comparison of Liniar's British-made, chambered PVC-U system against the more widely fabricated VEKA system.
Context
Before the numbers
Liniar is a comparatively modern, UK-designed PVC-U system, often presented on the strength of its chambered thermal design and British manufacture. VEKA is an older, more widely fabricated German system with a longer UK track record.
Both are genuinely capable mainstream systems. The comparison is really about manufacturing origin and range choice rather than one being definitively superior.
Side by side
On the points that matter
| Criterion | Liniar | VEKA |
|---|---|---|
| Appearance & sightlines | Casement and flush sash ranges available. | Chamfered, sculptured and flush casement styles available. |
| Range choice | Smaller, more focused range set built around the chambered design. | Broader range choice reflecting decades in the UK market. |
| Availability | Widely offered by UK installers, UK-manufactured. | One of the most widely fabricated PVC-U systems in Britain. |
| Typical cost position | Mainstream, often marketed on energy performance credentials. | Mainstream to upper-mainstream, competitive due to scale. |
| Best suited to | Homeowners prioritising a British-made system and energy performance. | Cost-conscious, whole-house replacement wanting maximum appearance choice. |
| What actually decides quality | The finished, whole-window U-value quoted, glass included — not frame marketing alone. | The fabricator's standard and the specific range and glazing quoted. |

The verdict
Liniar's marketing leans on thermal design and British manufacture; VEKA leans on scale, availability and appearance choice. Neither claim, on its own, tells you what you will actually get on your house.
Ask for the finished-window performance figures and the exact range in both cases, and compare those — not the marketing story behind each brand.
