Frame light more carefully
A cleaner frame for contemporary and traditional elevations.
Slimline aluminium can replace bulky frames, complement large doors or create a consistent new-build package. PM Windows balances fixed and opening sections, glazing, ventilation and sightlines across each elevation.
01
Better-balanced sightlines
Opening and fixed sections are composed to keep the elevation calm and coherent.
02
Ventilation that suits the room
Opening style and restrictors are selected around use, reach and cleaning.
03
Whole-home coordination
Frames, bars, colours and handles can connect windows with the wider glazing scheme.
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.
Frame style
Flush, sculptured, bevelled or slim aluminium options depend on the collection.
Glazing
Thermal, acoustic, privacy, safety and solar-control needs are considered.
Ventilation
Trickle ventilation and opening area are coordinated with Building Regulations.
Colour
Single, dual-colour, woodgrain and textured finishes vary by system.
Details
Handles, bars, cills and trims complete a consistent elevation.
Colours & finishes

Frequently asked questions
Useful answers before you choose.
Should fixed and opening windows look the same?
Balanced sightlines or dummy sashes can help. The right approach depends on the chosen system and the character of the building.
Do new windows need trickle vents?
Ventilation requirements depend on the project and existing provision. PM Windows will confirm the applicable Building Regulations route.
Can the windows coordinate with the doors?
Yes. We can align colour, profile character and hardware across compatible windows and doors.
