Bring daylight from above
Lift the ceiling without overcomplicating the roof.
A stronger ridge reduces unnecessary glazing bars and keeps attention on the sky. PM Windows aligns the lantern with the room below, then coordinates size, glass, vents, kerb, colour and internal finishing.
01
Put light where it matters
Roof glazing can brighten the centre of a plan where vertical windows cannot.
02
Control comfort as well as daylight
Glass, insulation, ventilation and solar control are considered together.
03
Engineer the complete opening
Kerb, structure, drainage, finishes and compliance are coordinated before installation.
Tailored to the project
The decisions we make with you.
The best result comes from resolving the technical and visual details together, then recording them clearly in the quotation.
Bar layout
A stronger ridge allows a cleaner arrangement with fewer glazing bars across the roof.
Glass specification
Thermal, solar-control and self-cleaning glass are considered around orientation and room use.
Ventilation
Manual or powered roof vents can be added where the room needs high-level ventilation.
Internal & external colour
Finishes can coordinate with the room inside and the windows and doors outside.
Kerb & finishing
Upstand, weathering, plaster lines, lighting and decorating are resolved before installation.
Colours & finishes
Quietly coordinated or deliberately contrasting.
Availability varies by product. Explore useful RAL starting points, compare finish types and save a shortlist before PM Windows confirms the exact options for your chosen system.

Frequently asked questions
Useful answers before you choose.
How do I avoid a room overheating?
The answer is a combination of glass specification, orientation, ventilation and shading. PM Windows will assess the complete space rather than relying on one headline figure.
Will Building Regulations be required?
It depends on whether the work is new, replacement, glazed, solid or structural. The applicable route will be confirmed before work begins.
Can lighting be incorporated?
Many roof and pelmet arrangements allow integrated spotlights or pendant positions when they are planned early.
