Custom Window Treatments for Bay Windows
TLDR;
Custom window treatments for bay windows are the best way to handle the angles, depth, and light control that standard blinds cannot solve. At
Simply Windows, we create tailored solutions that improve privacy, insulation, and style while ensuring a perfect fit for Boston and Westborough homes. With options like shades, shutters, drapery, and motorized treatments, the right custom solution balances design and function.
Why Bay Windows Deserve Custom Treatments

Bay windows are unique architectural features. Their angled design creates more space and natural light, but it also presents challenges that off-the-shelf blinds or shades cannot solve.
- Gaps form if treatments are not cut precisely.
- Light leaks are common with standard products.
- Privacy suffers when angles are not measured correctly.
In New England, bay windows also impact insulation. During cold winters, untreated bays lose heat. In summer, glare becomes an issue. Custom treatments resolve these problems by addressing fit, style, and function in a single solution.
Key Design Considerations When Choosing Bay Window Treatments

Light Control and Privacy Balance
The angles of a bay let in light from different directions. This requires treatments that manage sunlight without blocking views completely.
- Dual roller shades allow sheer coverage during the day and blackout at night.
- Layered treatments like drapery with blinds add flexibility.
- Privacy liners are useful for bedrooms or street-facing bays.
Energy Efficiency and Insulation
Custom window coverings improve energy savings. Fabrics and structures are selected to match Boston’s seasonal needs.
- Honeycomb shades trap air and reduce heat transfer.
- Blackout liners keep rooms warmer in winter.
- Woven woods with liners control both light and insulation.
Motorization and Smart Control
Bay windows are often large and hard to reach. Motorized solutions add convenience.
- Remote controls simplify daily adjustments.
- Smart shade systems integrate with voice assistants.
- Timed settings improve energy efficiency by aligning with sunlight patterns.
Mounting and Track Systems for Angled Windows
Mounting is one of the most critical parts of custom treatments.
- Inside mounts create a seamless look when the frame depth allows.
- Outside mounts work when angles prevent inside installation.
- Curved and segmented tracks ensure drapery flows smoothly across the bay.
Aesthetic and Style Matching
Custom treatments ensure design consistency.
- Fabrics range from sheer to blackout, with options like linen or woven woods.
- Layering combines blinds with drapery panels for a tailored look.
- Treatments match architectural style, whether traditional New England trim or modern minimalist interiors.
