A pergola already gives you a roof. Add glass walls and it becomes a garden room you can use from early spring to late autumn – sheltered from wind, rain and cool evenings, but still full of light. Here’s what to know about glazing a pergola in Ireland.

Frameless vs framed sliding glass
- Frameless sliding glass – panels run on a slim top and bottom track with no vertical frames, giving the cleanest view of the garden. Panels stack to one side to open the space completely.
- Framed sliding glass – each panel sits in a slim aluminium frame. More rigid and better sealed against draughts, a good choice for exposed gardens.



Glass, screens or both?
Glass is best for keeping wind and rain out while keeping the view. Zip screens – vertical fabric blinds that run in side channels – are better for shade, privacy and insects, and can be combined with glass on different sides of the same pergola.

Lighting and heating
LED strips built into the frame or louvres, plus an infrared heater, turn a glazed pergola into an evening space. Plan cabling at the start so wiring runs hidden inside the posts.
Which pergola works best with glass?
Both retractable and bioclimatic pergolas can be glazed. Bioclimatic louvred roofs are the most popular choice for year-round rooms because the roof itself is solid aluminium – see our retractable vs bioclimatic comparison.

For a hot tub or spa, glass sides give shelter while keeping the countryside view – one of the most popular uses we see in rural Ireland.
