The Problem We Solve

The window most
people leave bare.


Apex, triangular, and gable-end windows are increasingly common in modern homes — and they're almost always left without any covering.

Not because homeowners don't want to dress them, but because most blind companies simply can't do it properly. A standard rectangular blind dropped into an apex window leaves large triangular gaps at either side where light pours in uncontrolled. It looks wrong, fits badly, and defeats the entire purpose of having a blind.

The only answer is a blind made precisely to the exact shape of the window — following every angle and edge to the millimetre. That's exactly what we supply and fit.

Why Standard Blinds Don't Work

The Problem with Off-the-Shelf

Triangular Gaps

A rectangular blind hung in an apex window leaves large triangular gaps either side where light pours in uncontrolled. It looks wrong, fits badly, and defeats the entire purpose of having a blind.

Wrong Proportions

Standard blinds made to the width of an apex window hang too wide for the lower section and too narrow for the upper. No standard size can accommodate both the rectangular base and the angled head simultaneously.

Can't Reach to Operate

Even if a standard blind could fit, gable-end and high apex windows are physically impossible to operate manually. The only practical solution is a motorised blind controlled by remote, app, or voice from ground level.

Window Types We Cover

Any Shape. Any Angle.

True Triangular Windows

Three-sided windows with no horizontal base — the most challenging shape to cover and the one most companies decline. Our bespoke blinds are templated precisely to the triangle's exact geometry. The blind retracts fully to the apex point when raised, opening the window completely.

Motorised recommended

Apex Windows

A rectangular window with a triangular head above — the most common shaped window in new-build homes. Our blind covers the entire glazed area from the sill to the apex point, raising and lowering fully. When open, the fabric retracts to the apex for an unobstructed view.

Gable-End Windows

Large triangular or irregularly shaped glazing at the gable end of a building — often very wide and tall. We manufacture bespoke blinds for gable-end windows of considerable size, including motorised options where manual operation would be impractical due to height.

Motorised recommended for large gables

Pentagon & Irregular Shapes

Five-sided windows, irregular polygons, and any other non-standard shaped window can be covered with a bespoke blind. We template each window individually — the blind's profile follows the exact outline of your glazing. Whatever the shape, if it's glazed, we can shade it.

Templated to any geometry

Arched & Curved Tops

Windows with arched or curved heads — including semi-circular and elliptical tops — can be covered with a shaped blind that follows the curve precisely. Where the arch sits above an opening section, we treat each part separately for independent light control.

Shaped to follow the curve

Combination Windows

A standard rectangular casement beneath a fixed shaped light. We treat each section appropriately — the shaped section receives a bespoke apex blind, the lower opening section a standard made-to-measure blind. Each operates completely independently.

The Technical Detail

How Apex Blinds Actually Work

A standard blind mechanism cannot follow a non-rectangular profile — the fabric hangs straight and square, leaving triangular gaps wherever the window diverges from a rectangle. An apex blind solves this with a specially designed mechanism and a fabric cut to the exact shape of the window.

The key is precision templating. We take a template of your exact window opening — not just measurements, but the precise geometry — and the blind is manufactured to that template. The result is a blind that follows every angle and edge of your window with no gaps.

Operation varies by shape. Rectangular windows with triangular heads raise and lower normally. Pure triangular windows typically operate on a tilt-only mechanism. Very large or high windows are always motorised for practical access.

01Precision Templating

We take a physical or digital template of your exact window — capturing every angle, edge, and dimension with complete accuracy. No guesswork, no approximations.

02Bespoke Manufacture

Your blind is manufactured to the exact template — fabric cut to the precise shape, mechanism specified for the window geometry and operation method.

03Professional Fitting

Our own fitting team installs the blind precisely within your window frame. The fabric follows every edge with no gaps. Motors are programmed and remotes configured.

04Full Demonstration

We walk you through the full operation of your blind before we leave. You're never left to figure it out yourself.

New Build & Renovation

Pair with Blindspace® —
hidden in the ceiling.

If you're building or renovating, there's an even more refined option. When a Blindspace® concealed cassette is incorporated into the ceiling void above an apex or gable window during construction, the entire blind mechanism disappears completely — no visible headrail, no visible cassette, nothing. The blind deploys silently from the ceiling and retracts back into it.

The critical thing is timing. Blindspace® cassettes need to be built into the ceiling structure before plastering and finishing — which means getting in touch with us early in the build process. We work directly with architects, builders, and self-builders to specify and coordinate the installation at the right stage. Once the ceiling is finished, this option is no longer available.

Talk to Us Early

The Result

A completely invisible installation. No headrail, no visible mechanism. The blind appears from the ceiling and disappears back into it — the cleanest possible finish for a shaped window in a high-specification home.

When to Contact Us

Before first fix — ideally at the structural or framing stage. We can advise on cassette sizing, ceiling void requirements, and motor cable routing so everything is ready when the plasterers arrive.

Who It's For

Self-builders, architects, interior designers, and anyone undertaking a significant renovation. We're experienced working from drawings and specifications at any stage of a project.

Fabric Options

Choose Your Fabric

Dimout

Soft light filter · Most popular

Our most popular fabric for apex windows. Dimout fabric filters sunlight beautifully — reducing glare and softening the light entering the room — while maintaining a view through the window when partially raised. Available in a wide range of warm neutrals, greys, and tones.

Blackout

Full light block · Bedrooms & media rooms

Blackout fabric lined with a specialist layer that blocks light completely. Ideal for bedrooms, home cinemas, and any room where total darkness is needed. Due to the angled geometry of shaped windows, a small amount of edge light may filter at extreme angles — minimised by our precision fitting process.

Thermal & Honeycomb

Energy efficient · Glazed extensions

Honeycomb pleated fabric traps a layer of air within the cells, providing excellent thermal insulation — reducing heat loss in winter and heat gain in summer. Particularly valuable for gable-end windows and apex windows in extensions where large areas of glass significantly affect room temperature.

Motor Power Sources

Powering Your Motorised Blind

Motorised apex blinds don't always need an electrician. Most of our installations use battery or solar power — clean, wireless, and completely self-contained.

Battery Powered

Most popular · No wiring needed

A rechargeable battery pack powers the motor — no mains wiring, no electrician required. Typically lasts 6–12 months between charges depending on usage. Recharges via USB, usually without removing the blind from the window. The simplest and most flexible installation option.

Solar Powered

Self-sufficient · South-facing gables

A small solar panel continuously charges the battery from ambient daylight — completely self-sufficient with no charging cable required. Ideal for south and west-facing gable windows where direct sunlight keeps the panel topped up automatically. Zero ongoing maintenance.

Mains Wired

New build · Zero maintenance

A discreet mains spur provides continuous power — zero battery management, zero charging, unlimited operation cycles. The definitive solution for new builds and major refurbishments where cable routes can be incorporated during construction. Requires a qualified electrician.

Motor durability  — The motors we use are engineered for long-term residential use, tested to tens of thousands of operation cycles with consistent, whisper-quiet performance throughout. We'll specify the right motor for your blind size, fabric weight, and usage during your survey.

Operation Options

How You Operate Them

Remote Control

A sleek remote operates your blind from anywhere in the room — ideal for high windows and gable ends that can't be reached easily. Up to 16 channels lets you control individual blinds or groups simultaneously.

Smart App & Voice

Integrate with your smart home for app and voice control via Alexa, Google Home, or Apple HomeKit. Schedule the blind to open or close at set times — particularly useful for south-facing gables that heat up predictably.

Wall Switch

A discreet wall switch gives fixed-point control — ideal where the blind is above a landing, stairwell, or other fixed position. Can operate a single blind or a group simultaneously.

Manual Pull Cord

For accessible apex windows at normal height where a simple, reliable manual operation is preferred. A neat side-pull cord operates the blind without motorisation — straightforward and maintenance-free.

Your Questions Answered

Apex Blinds FAQs

In the vast majority of cases, yes. Triangular windows, apex windows, gable-end windows, arched windows, pentagons, and most other irregular shapes can be covered with a bespoke blind made to the exact geometry of your window. Very unusual shapes may require a site visit before we can confirm, but if you have a shaped window that's currently uncovered, it's almost certainly something we can help with.

It depends on the exact shape. For apex windows (rectangular with a triangular top), the blind raises and lowers normally — retracting to the apex when fully open. For pure triangular windows with no horizontal base, the blind typically operates on a tilt mechanism rather than raise/lower. We'll explain exactly how your specific window's blind will operate during the survey.

Not always — but motorisation is strongly recommended for any window that's difficult or impossible to reach by hand. Gable-end windows high on a wall, apex windows above a staircase, and any window above head height are natural candidates. For accessible windows at normal height, a manual pull cord is perfectly practical.

The whole point of a bespoke apex blind is that the fabric follows the exact outline of your window — so gaps should be minimal or non-existent. With blackout fabric on extreme angles, a very small amount of edge light may be visible where the fabric meets the frame — this is inherent to the geometry and is minimised by our precision fitting process.

Bespoke shaped blinds typically take 3–5 weeks from order to installation, depending on complexity and the manufacturer's lead time. Motorised systems may take slightly longer. We'll give you a clear timeline at the point of ordering.

This is especially important for shaped windows where the choice of fabric affects both the appearance and the practical performance of the blind.
