Solar shades that cut the glare without taking your view

How a solar shade works

The fabric is woven with tiny, regular openings. Light scatters against the yarn and arrives softened; your eye still resolves the view through the holes. The result is a window you can look out of on a bright afternoon without squinting, and a room that is several degrees cooler than the same room with bare glass.

It is the only window covering that solves glare without solving it by making the room dark. That is why offices use them and why people with a view refuse anything else.

Openness: the number that decides everything

Openness is the percentage of the fabric that is open weave. It runs from about 1% to about 14%, and it trades view against control in a straight line.

• 1% – 3% — strongest glare control, most daytime privacy, softest view. Good for home offices, screens and street-facing rooms.
• 5% — the common middle. Meaningful glare control with most of the view intact. Most living rooms end up here.
• 10% and above — the view stays sharp, but a low western sun will still reach you. Best on windows that are not in direct afternoon sun.

Colour matters as much as openness, and most people guess wrong. A dark fabric absorbs light and gives a crisp view out; a white fabric bounces light around inside the weave and can glow, washing the view out. For a window you actually look through we almost always steer people to charcoal, bronze or a deep grey.

What they do about heat

On a west-facing window in the Valley, afternoon sun is the single largest heat load in the room. Stopping it at the glass is far more efficient than removing it afterwards with air conditioning, and you feel the change in the first hour.

Solar shades also block a large share of UV, which slows the fading of hardwood, rugs and upholstery. That is the kind of benefit nobody notices for three years and then notices permanently.

The night problem, and the standard fix

Solar shades work on contrast. Daytime, the outside is brighter, so you see out and nobody sees in. After dark that flips exactly: your lit room is the bright side.

If the window faces a street, a sidewalk or a neighbour's house, the normal answer is a dual roller — a solar fabric for the day and a blackout or privacy fabric behind it for the night, both on one bracket, both under one valance. Motorize it and the whole window changes state on a schedule.
