The blind that insulates both ways.
Cellular blinds trap a layer of still air in honeycomb cells — a soft-looking blind doing serious thermal work on single-glazed sash windows, July and January alike.
Where the cells earn their keep
Three places a honeycomb belongs.
The trapped-air principle is the same everywhere — what changes is the fabric density and how the blind is held.
Bedrooms & nurseries
Light-filtering cells for a soft glow, blockout cells for proper sleep — and cordless or motorised operation so nothing dangles near a cot.

Draughty sash rooms
An inside-mount honeycomb sits in the recess like a second skin for the glass — the biggest comfort upgrade an unaltered heritage window can get.

Skylights & shaped glass
The same trapped-air logic, tensioned on side wires for roof glass, gables and arches — usually motorised, because nobody reaches a skylight twice a day.

Old houses lose heat the same way they gain it.
Single glazing, tall ceilings and roof spaces insulated to 1920s standards — this is the suburb the honeycomb was made for.
A buffer for single glazing
Most period windows here still carry their original single panes. The still-air layer in a cellular blind is the least invasive way to slow heat leaving in winter and arriving in summer — no reglazing, no altering the frame.
Kind to heritage frames
Cellular blinds are light. Slim inside-mount brackets carry them in the recess without stressing old timber, and outside-mount versions fix to the wall where a sash is too fragile to drill.
Quiet, in both senses
The cells soften sound as well as heat, and the blind raises to a stack a few centimetres tall — the park view stays the point of the room.
Privacy that keeps the light
Rooms at walking height to the street hold their privacy behind translucent cells that still glow with the garden's light all day.
Questions
Asked at almost every cellular measure.
Do cellular blinds really make a temperature difference?+
Yes — trapped air is a genuine insulator, which is why double glazing works. A honeycomb blind holds a still-air layer against the glass; on a single-glazed room you feel it most on winter evenings and hot late afternoons. It supplements the glass, it doesn't replace double glazing.
Light-filtering or blockout cells?+
Living rooms usually take light-filtering — the glow is lovely. Bedrooms take blockout cells, which line the honeycomb so the room darkens properly while keeping the same slim stack.
Can they be motorised?+
Yes — and for skylights, tall stairwell glass and kids' rooms it's the recommendation: quiet motors, no cords at all, and a schedule that closes the house against the afternoon heat before you're home.
Where we fit them
Cellular blinds, for single glazing across four suburbs.
The same trapped-air principle answers the same problem wherever it turns up on this side of the ridge — single-glazed sash and casement windows in period homes we measure right across the parks belt.
