You Called Three Companies.
All Three Said No.
“We only make rectangular shades.” Two companies didn't even let you finish describing the window.
Triangle windows in gable ends and A-frame walls get direct sun but are nearly impossible to shade with off-the-shelf products.
You searched online and found stock photos, vague “call for quote” pages, and zero real pricing.
Your window isn't the problem. The industry is.
We precision-cut right triangle shades to your exact angles and dimensions — the left side follows your roofline slope perfectly.
You've got a triangle window with the right angle at the bottom-left corner and the angled side rising to the right. You called a few shade companies. They either said "we don't do triangles" or quoted you four figures with a 6-week lead time.
We built our production line specifically for shapes like this. A left right triangle shade requires precision cutting at exact angles — the fabric must follow the slope of your roofline or architectural angle perfectly. Off by even ¼" and it looks wrong.

How to Measure Your Right Triangle – Left Window
Measure the bottom width — the horizontal base of the triangle from the left corner to the right corner.
Measure the left angled length — from the bottom-left corner up along the angled/sloped side to the peak.
Measure the right height — the vertical side from the bottom-right corner straight up to where it meets the angled side.

Common Questions
Right Triangle – Left Shade FAQs
Stand inside your room facing the window. If the right angle (the square corner) is at the bottom-left, it's a Left Right Triangle. If it's at the bottom-right, it's a Right Right Triangle. The angled side slopes in the opposite direction.
Triangle shades are stationary — they mount in a fixed position covering the window. Motorization applies to rectangular shades that roll up and down. For triangles, the shade is permanently deployed.
It depends on the window's orientation. South-facing triangles in gable ends get intense direct sun — a solar fabric with high UV blocking (like our SkyShade 1P or EcoTherm collections) works well. For bedrooms, a blackout fabric prevents early morning light from the peak.
Triangle shades come with mounting brackets along the straight edges. The shade stretches taut across the frame using a tensioned cable or rod system. We include all hardware and detailed installation instructions specific to your shape.
