From the light sliding unit to the large lift-and-slide door where a couple of hundred kilos of glass moves aside with one hand. We advise which system can carry your opening – and what is needed under the floor.

Our best-insulated sliding unit. The obvious choice if the living room faces north or west and the opening is large.

Classic lift-and-slide door (HS). The sliding leaf is lifted clear of the seal before it moves – which is why it is both tight and easy to operate.

The same HS mechanics with aluminium outside. For facades exposed to wind and driving rain.

The light, compact sliding unit for smaller openings – balcony doors, holiday homes and sunrooms.
Uw measures how much heat disappears through the window. Lower is better. Here are our PVC systems set against each other.




A conservatory has to stand on something load-bearing. We look at the base and foundation before we talk about glass.
This is where leaks start. The roof pitch can be set from 5 to 45 degrees so the structure follows the house’s own roof.
A south-facing glass roof gets hot. We talk about shading and glazing before you end up with a greenhouse.
The pergola sides can close with ZIP screen or glass, and the conservatory can have sliding units – so the room works in July and in February.
One more room – without moving a single wall.
