Liniar uPVC windows
uPVC windows manufactured in Bristol.
Energy-efficient, secure and made to measure at our Bristol factory, with supply-only and complete installation options.
01
Designed around the opening
Each Liniar uPVC window is made to the confirmed size and arranged for the room. Fixed panes, top-hung vents and side-hung openings can be combined while keeping the external elevation balanced.
02
The complete specification matters
The 70 mm frame is only the starting point. Standard or EnergyPlus profile, insulated glass unit, reinforcement where required, gaskets, locking, vents, handles, cills and finish together form the window being quoted.
- Made to measure
- Clear specification before manufacture
- Supply only or local installation
03
Supply only or professionally installed
Supply-only customers approve their manufacturing sizes and schedule. For local installation, our survey checks the opening and final choices before the order is released to the Bristol factory.
Planning and specification
What to consider when specifying practical, low-maintenance uPVC windows
A good quotation begins with the property and the way the opening will be used. We look at opening positions, glass, trickle ventilation, safety requirements, handles and colour. The best answer is not always the same for every room, so it is worth considering privacy, daylight, furniture positions and how often an opening will be used before settling on a specification.
Master Plastics can discuss Liniar uPVC systems manufactured to the confirmed sizes in Bristol. We manufacture made-to-measure products in Bristol and can provide supply only or professional installation across Bristol and nearby areas, depending on the project. Installed work is surveyed before manufacture; supply-only customers remain responsible for confirming their order sizes and fitting requirements.
From first enquiry to finished order
Tell us which panes need to open, whether existing vents are present and if any room has a particular privacy, safety or escape requirement. We can then prepare a Liniar configuration around those needs.
The quotation will identify the selected profile, insulated glass unit, colour and hardware. Performance figures vary by configuration, so any required U-value, energy rating or security standard must be agreed before manufacture.
Liniar system detail
A 70 mm window with choices behind the headline
The Liniar casement range uses a 70 mm frame and is available in standard and EnergyPlus profile options. The system can accept 28 mm, 36 mm or 40 mm insulated glass units, although the correct combination depends on the window and performance required.
- Sculptured or chamfered profile appearance
- Four-chamber standard or six-chamber EnergyPlus options
- Double- and triple-glazed configurations where suitable
- Multi-point locking, with PAS 24 configurations available when specified
Liniar publishes whole-window performance up to A++ and U-values as low as 0.81 W/m²K for qualifying configurations. Your quotation will identify the specification actually being supplied.

Questions about upvc windows
Which uPVC window system do you use?
We manufacture Liniar uPVC windows in Bristol. The exact profile, glazing, colour, hardware and ventilation specification is confirmed for each order.
Can Liniar windows take triple glazing?
Liniar’s 70 mm casement system can accommodate 28 mm, 36 mm or 40 mm insulated glass units, subject to the chosen profile and project specification.
How should uPVC windows be maintained?
Clean frames with mild soapy water and keep drainage routes clear. Opening hardware benefits from periodic inspection and light lubrication in accordance with the hardware manufacturer’s guidance.
