Apex Curtains / Made for your architecture
We survey, design, manufacture and professionally install made-to-measure curtains for apex, triangular, angled and gable-end windows across England and Wales.
An Apex installation · Real homes, individually dressed
01 / Recognise the shape
Choose the closest shape. See the possibilities, understand the practical details and find the right place to begin.
Apex
Two roof slopes and changing drops need to be measured together. We plan shaped curtains, an aluminium track route and the way the panels gather around your window.
The peak, side heights and stack-back must work as one design. Some upper sections may remain in place when the curtains are tied back.
Gable end
A gable can combine a roof-shaped top with full-height glazing below. Curtain weight, the number of panels and the open stacks all influence the right arrangement.
The fixing structure and safe access need assessment before manufacture. The tallest point alone does not describe the installation.
Triangular
A sharp triangular shape needs carefully planned panel geometry, heading depth and retention along the slope. Tiebacks can reveal the centre while leaving a soft frame above.
A sloping track does not behave like a horizontal rail. Full glass clearance should never be assumed.
Angled / sloping
Single slopes and asymmetric windows need their own measurements. We establish the true angle, track position and finished drop at each part of the curtain.
Do not assume opposite sides are symmetrical. The opening route, retained sections and tiebacks must suit the actual shape.
Double-height
On very tall windows, fabric drape, joins and the total lined curtain weight matter as much as colour. The track and fixing strategy are selected around the finished curtain.
A sample cannot show the behaviour of a 4–6 metre drop. Safe installation and later maintenance access need planning too.
Large glazing
Wide rectangular glazing still needs the right track capacity, heading clearance and stack-back. We plan where the curtains will sit in relation to doors, handles and the view.
More fullness means more cloth, weight and stack. The open curtain needs space as well as the closed curtain.
I’m not sure
You do not need to know the technical name for your window. A clear photograph and approximate dimensions help us understand the room and start the conversation.
Approximate dimensions are for an initial discussion. The specialist survey establishes the final geometry, structure and manufacturing measurements.
Window descriptions can overlap. A gable may also be apex-shaped and double-height; the actual geometry determines the design.

02 / Design your look
Start with a colour family, then explore the mood. Discover Oslo fabrics by Prestigious Textiles, materials that sit well together and the details that complete the scheme.
Illustrative palette colours. Make the final choice from a physical fabric sample.
Greens
Sage, olive, moss and deep green offer different ways to connect a room with the landscape. Sage feels muted and airy; olive adds warmth; moss gives depth. The Oslo examples below explore olive and yellow-green directions, rather than representing every green subtone.
Let the glazing and a restrained colour palette lead. A clear heading rhythm and tonal tiebacks give the cloth a composed architectural line.
PT fabric imagery represents 140 cm width × 1 m length, reduced here for preview. Screen colours, lining and room light affect appearance.
Enter the colour studio ↗Complete the composition
Matching tiebacks make a continuous sweep; a warm neutral contrast brings the wall palette into the cloth. Compare coloured lining where the reverse shows, alongside the required light control.
Choose lining for privacy, light control and the room’s needs. A coloured reverse adds a design choice; its colour alone does not establish blackout or thermal performance.
03 / Real homes, thoughtfully resolved
Milton Keynes / Apex master bedroom
The challenge. Dress an apex bedroom window while balancing the shape, privacy and the open view.
The approach. The project records wave pleat curtains, blackout lining and a bespoke track. The gathered cloth shows how folds and tiebacks become part of the composition.
Read the project story ↗Peterborough / Triangular bedroom glazing
The challenge. Improve privacy and light control while giving a shaped bedroom window a softer finish.
The approach. Made-to-measure pencil pleat curtains with blackout lining. Deep blue frames the glass, while the timber brings warmth to the palette.
Read the project story ↗04 / Every detail has a purpose
Standard off-the-shelf systems are often unsuitable for angled glazing. Track position, curtain weight, fixing structure and stack-back need to work together. Explore the detail that matters to your room.
Aluminium systems, secure support and a route designed around the slope.
Drape, privacy and light control, with the edges considered as carefully as the cloth.
The right working position, safe access and a beautifully dressed finish.
Choose the fold and rhythm that suit the cloth and the room.
Proportion, positioning and the amount of glazing left in view.
The true angles, changing drops, floor line and fixing points.
Light, considered
Compare the lining, then look around its edges. Fabric performance and the way a curtain covers the window are separate parts of light control.
Reduces light passing through the lined cloth. Top, side, meeting-edge and floor gaps can still admit light.
Explore all lining options ↗Floor-length curtains can reduce leakage at the bottom. Track positioning and overlaps can help at the edges, but installation geometry may prevent total darkness.
The line behind the curtain
Apex aluminium tracks include Forest KS and CS. We select the system around the complete curtain weight, fixing structure and shaped route.
Finish illustration only, not an exact KS/CS profile or installation drawing. White is normal; black is quoted as an upgrade.
Compare Forest KS, CS and fixings ↗Shape the view
Hanging, gathering and travelling sections create different silhouettes. Your surveyed layout determines which movements are possible.
Illustrative arrangements, not before/after photographs or a promise of full opening. Sloping sections may be retained; not every curtain can travel into an open stack.
Explore tiebacks and visible coverage ↗In this Apex installation, the gathered cloth reveals the central glazing while retaining a fabric frame along the slope. The position and size of the tieback are part of the design.
Find the right finishing detail ↗05 / One considered service
Survey, design, manufacture and installation belong together. Each stage resolves the details needed for the next.
Tell us about the room, the window and how you want it to feel. A photograph helps us understand where to begin.
Your priorities: privacy, light, warmth, the view and the interior.
We assess dimensions, roof angles, fixing surfaces, working height and the space available for the curtains.
Geometry, structure and safe access are considered together.
Choose the cloth, lining and heading, then resolve the track, stack-back, tiebacks and finished floor line.
The practical arrangement and the room palette become one scheme.
Curtains are made for the measured installation, with the agreed shaped panels, drops and finishing details.
A bespoke construction for the window and chosen specification.
Fit the specified track and curtains using suitable fixing points and a planned access method for the room.
MiTOWER or other high-level access where the site assessment requires it.
Dress the folds, check the agreed movement and clearances, and explain everyday use and aftercare.
A considered finish, with guidance for living with your curtains.

The difference is in the planning
A small error in an angle or drop can change the whole curtain line. The geometry, fixing position, track, curtain weight and stack-back need to be resolved before the cloth is cut.
Then there is the room itself: light gaps, high-level access and the finished floor. A specialist survey brings those decisions together, with fewer assumptions left for installation day.
Why DIY apex curtains can go wrong ↗What is actually possible? ↗
The work. The experience.
Explore a curated selection of real customer reviews alongside our completed projects. Look closely at the folds, the roofline and the way each curtain sits within the room.
For considered spaces, from the outset
Bring the curtain into the conversation early. Track locations, recesses, fixing provisions, curtain weight, stack-back and access all influence the finished architecture.
Discuss motorisation requirements before finalising the design: shaped routes and retained sections need individual assessment.
