UPVC Doors & Windows

The full Liniar range of windows and doors, from a single casement to a seven pane bi-fold, in nearly forty colours. Supplied and fitted across Northampton and the villages around it.

  • Liniar casement window in Agate Grey set in a stone wall
  • Liniar residential door in red under an arched brick porch
  • Liniar French doors in Irish Oak opening onto a patio

One system for every window and door in the house

Tommy fits the Liniar range, designed and made in Derbyshire. Every window and uPVC door on this page is built from the same family of frames, so a new back door matches the kitchen window and the bay at the front matches both. Have a look through, get a rough idea of what you like, then give us a ring. We will bring samples, measure up and give you a fixed price.

Windows

Nine ways for a window to open, all in the same frame family. Tap a colour under any picture to see it in that finish.

Measuring up, fitting and the 10-year guarantee are all on our uPVC window installation page.

    The window most British houses already have, hinged at the side or the top. It suits nearly any house, and it is where most of our window jobs start. You decide how each pane opens, then choose the edge shape, any bars and the colour.

    • Side hung, top hung and fixed panes in any mix
    • Standard, EnergyPlus or EnergyPlus90 frame
    • Sculptured (curved) or chamfered (bevelled) edges
    • Georgian bars, arched heads and patterned glass if you want them

    Flush sash windows

    Shown in Chartwell Green

    On an ordinary casement the opening part stands proud of the frame. On a flush sash it sits level with it, the way a joiner would make a timber window. In a woodgrain foil most people walking past would take them for wood, which is why they get used on cottages and where planning has been fussy about uPVC.

    • 70mm frame with a 50mm sash
    • Welded corners for a crisp look, mechanical joints for a heritage one
    • A+ energy rating, U-values down to 1.2 W/m²K
    • Sash and frame can be different colours
  • Resurgence window in WhiteResurgence window in CreamResurgence window in ClaystoneResurgence window in Agate GreyResurgence window in Pebble GreyResurgence window in Anthracite GreyResurgence window in Gale Grey FinesseResurgence window in Black/Brown

    Resurgence windows

    Liniar's best flush sash, and the one to look at for a period house. It has two seals instead of one, both hidden, so there is no rubber or brush strip showing in the gap round the sash. The foil carries on into the parts you only see with the window open, so it still looks like timber then too.

    • 80mm frame with a 70mm sash
    • Energy ratings up to A++
    • Double, triple or acoustic glazing
    • Welded, mechanical or Timberweld corner joints

    In a conservation area, on a listed building or under an Article 4 direction, check with the council before ordering. Some accept a timber-look uPVC window and some do not.

    Tilt & turn windows

    Shown in White

    One handle, two ways of opening. Turn it one way and the top of the window tips in a few inches for air, and you can leave it like that when you go out. Turn it the other and the whole window swings into the room, so you can clean the outside from indoors.

    • Opens inwards, so nothing sticks out over a path
    • Usually set to tilt first, so a child cannot swing it wide open
    • Can be made larger than a casement
    • U-values down to 0.9 W/m²K
  • Reversible window in WhiteReversible window in Anthracite GreyReversible window in Black/BrownReversible window in Golden OakReversible window in Rosewood

    Reversible windows

    Shown in White

    The sash spins right round so the outside of the glass ends up facing you, and it does it without swinging into the room and catching the blinds. Worth thinking about for any window you cannot get a ladder to, like the one above a conservatory roof or high up on a town house.

    • Rotates a full 180 degrees
    • Flush finish inside and out
    • Chamfered profile, in solid or woodgrain colours
  • French window in White

    French windows

    Shown in White. Ask about other colours.

    A pair of sashes that open from the middle like a set of French doors, with no post left in the way once both are open. That gives a big clear opening, which is why we suggest them for bedrooms that need a proper escape route.

    • Full width opening with no centre post
    • Child restrictors available
    • U-values down to 0.8 W/m²K
  • Bi-fold window in WhiteBi-fold window in CreamBi-fold window in Agate GreyBi-fold window in Anthracite GreyBi-fold window in Black/BrownBi-fold window in Golden OakBi-fold window in Rosewood

    Bi-fold windows

    Shown in Anthracite Grey

    The panes fold back to one side so the whole window opens up. Good over a kitchen worktop that looks onto the garden, or anywhere a bi-fold door would take more wall than you want to lose.

    • Up to four panes wide
    • Up to 1800mm high
    • 28mm double glazed
  • Bay window in White

    Bay and bow windows

    Shown in White. Ask about other colours.

    A bay is a run of windows set at angles, a bow is the same idea on a gentler curve. Either one pushes the room out a little and brings light in from three sides. We build them from casement or flush sash windows, and the joints between them are smooth on the inside, so there is nowhere for dust to sit.

    • Casement or flush sash windows
    • Double or triple glazed
    • Georgian bars, leaded glass or sash horns
  • White sash horn windows with the top lights open, on a red brick extension

    Sash horn windows

    Pictured in White. Ask about other colours.

    A casement window made to look like an old sliding sash, down to the little horns on the frame. It opens on hinges instead of sliding, so there are no cords or weights to go wrong, and it locks with shootbolts like the rest of the range.

    • Looks like a box sash, opens like a casement
    • Shootbolt locking
    • Georgian bars to finish the look

Doors

Front doors, back doors and the big openings onto the garden. The colour dots work the same way as the windows.

    Residential doors

    Shown in Dark Red

    A uPVC front or back door made from the same frame as the windows, so the two match exactly. Each one is made to measure with your choice of panels, glass, side panels and hardware. A sensible back door, and a smart front one if you do not need a composite.

    • Made to order, with matching side panels
    • PAS 24:2015 and Secured by Design
    • Part M low threshold available
    • Double or triple glazed
  • Stable door in White

    Stable doors

    Shown in White. Ask about other colours.

    A residential door split across the middle, so the top half can open while the bottom stays shut. It keeps the dog in and lets the air through, and it looks right on a cottage or a kitchen that opens onto the garden.

    • Top and bottom open together or on their own
    • Same frame and locks as a residential door

    French doors

    Shown in Irish Oak

    Two doors that open from the middle with no fixed post between them, so you get the full width when both are open. They can open into the room or out onto the patio, and side panels make them work in a wider opening.

    • Open inwards or outwards
    • Side panels for wider openings
    • PAS 24:2015 and Secured by Design
    • U-values down to 1.0 W/m²K with triple glazing
  • Patio door in White

    Liniar's ModLok sliding door. Each sliding panel runs on eight small wheels instead of the usual four, which is why it glides rather than rumbles. Aluminium inside the frame stiffens it and carries the locks. If access round the back of your house is tight, the frame can come in pieces and go together on site.

    • Two, three or four panes, up to two of them sliding
    • Eight mushroom-head locking points
    • Low or Part M threshold with no trench to dig
    • A midrail, or even a letterbox, if you want one

    Standard bi-fold doors

    Shown in White

    The plain and simple way to open up the back of the house. Up to four panes that fold back to one side, in the same sculptured shape as the windows. Of the three Liniar bi-folds it is the most affordable.

    • Up to four panes wide
    • U-value of 1.3 W/m²K with double glazing
    • Part M low threshold available

    ModLok bi-fold doors

    Shown in Golden Oak

    uPVC outside with an aluminium frame running through it, which lets it span wider than the standard door. The locking is the serious part: hooks and shootbolts on the main door, anti-lift bolts on every other one, and the main door always has to open first, so nobody can force the wrong leaf.

    • Up to seven panes wide
    • PAS 24:2015, Secured by Design and Part Q
    • U-values down to 1.0 W/m²K with triple glazing
    • Woodgrain foils available

    Alumina bi-fold doors

    Shown in Anthracite Grey

    An aluminium bi-fold shaped to match uPVC windows, so you can have aluminium at the back without it looking out of place beside everything else. Being aluminium it goes bigger, and it runs on the bottom track so the lintel is not carrying the weight. Also made as a front door and as French doors.

    • Up to seven panes, each up to 2.5m high
    • Openings up to around six metres
    • Foiled to match your windows, or sprayed any colour
    • Low threshold just 23.5mm high

    Composite doors

    Our composite front doors come from a separate range, with its own page: fifty styles in thirty colours, every one pictured, plus glass designs and door furniture.

    See the composite range

Reading a bi-fold layout

Bi-folds are described with three numbers. The first is how many panes there are, the second how many fold one way, the third how many fold the other. So a 4-3-1 is four panes, three folding to one side and a single door on its own at the other, which is handy for nipping out without opening the lot.

  • 3-3-0
  • 4-3-1
  • 4-4-0
  • 5-5-0
  • 6-3-3
  • 7-6-1

Standard bi-folds go up to four panes. ModLok and Alumina go up to seven. Any of them can open in or out, with the main run to the left or the right.

Patio door layouts

On a patio door, O is a fixed pane and X is one that slides. Looking from outside:

OX / XO
Two panes, one fixed and one sliding
OXO
Three panes, the middle one slides
XOO / OOX
Three panes, one end slides
OXXO
Four panes, the middle two slide apart

How they look on a house

A picture of a window on a white background tells you its shape. On a house it tells you whether the colour works with the brick and the roof.

38 colours

The colour is a foil bonded to the frame at the factory, not paint, so it will not flake or need redoing. It can go on the outside only, or both sides, so you can have grey outside and white in the bedrooms. Under the foil the frame itself can be white, cream, caramel, brown or black, which matters with dark colours because it is the edge you see when the window is open.

Colours on screen are only a guide. Screens vary and woodgrain never photographs quite right, so ask us to bring the swatch book before you decide. Not every colour is made on every product, and some take a little longer to arrive.

Three frames, the same look

Most of the windows and doors above come in more than one frame depth. Inside each frame are hollow chambers that slow heat on its way out. More chambers, warmer house. The U-value is how much heat gets through, so lower is better.

  • Standard

    Depth
    70mm
    Chambers
    4
    U-value from
    1.2

    Four chambers inside the frame. It already beats most uPVC windows on heat loss, and it is the right choice for most houses.

  • EnergyPlus

    Depth
    70mm
    Chambers
    6
    U-value from
    0.8

    Six chambers in the same size frame, so from outside you cannot tell it from the standard one. It reaches A++ without needing special glass or inserts.

  • EnergyPlus90

    Depth
    90mm
    Chambers
    9
    U-value from
    0.6

    A deeper frame with nine chambers. It was the first uPVC window in the UK certified to Passive House standard, and it cuts outside noise by up to 42 decibels. Chamfered edge only.

U-values in W/m²K, for the frame and glass together at their best. Your quote will give the figure for the windows you actually order.

  • The seal

    Liniar's bubble gasket is made as part of the frame rather than pushed in afterwards, and it runs unbroken round the corners. That is where draughts usually find their way in on older windows.

  • Energy ratings

    Windows are rated from A++ down to E on the BFRC scale, which measures how well a window keeps heat in, keeps wind out and resists condensation. Liniar windows can reach A++. The final rating depends on the glass, so we will confirm it on your quote.

  • Sculptured or chamfered

    Sculptured frames have a soft curved edge, chamfered ones a flat bevel. Sculptured tends to suit older houses, chamfered newer ones, but it is really down to taste. Not every product comes in both.

  • Glass

    Most of the range takes either 28mm double glazing or 36mm triple glazing. Triple is warmer and quieter but heavier and dearer, so it is worth talking through which rooms it makes sense for.

Options and finishing touches

The things that come up when we measure up. None of them are compulsory, and we will tell you if one is not worth the money for your house.

  • Georgian bars

    Liniar's bars go on both faces of the glass, so they look like proper glazing bars rather than a grid trapped between the panes. They snap in before the glass goes in and do not come off when the window is cleaned.

  • Arched heads

    The frame can be bent to follow an arched opening, so a curved top no longer means a square window with a filled-in gap above it.

  • Patterned and decorative glass

    A wide choice of patterned, etched and coloured glass for windows, doors and side panels, in double or triple glazing. We bring samples when we measure up.

  • Thresholds

    Doors come with a uPVC frame all round and an optional cill. A low aluminium threshold or a full Part M level threshold is available if a wheelchair, pram or anyone unsteady on their feet uses the door.

  • Handles and hardware

    Locking handles as standard, in a good range of styles and colours. Patio and bi-fold handles come in black, white, dark chrome, light chrome and gold.

  • Child restrictors

    They go on nearly every window in the range and stop it opening more than a few inches.

  • Hinge guards

    An extra bit of security on the hinge side, so the opening part cannot be levered out from outside.

  • Escape windows

    Bedrooms upstairs usually need a window big enough to climb out of in a fire. French windows and tilt & turn windows give the widest clear opening for the size.

  • Matching fascias and soffits

    Liniar make roofline boards in the same foils as the windows, so the whole front of the house matches. Their fascias are 20mm thick rather than the usual 16mm, and carry the same ten year guarantee.

Need the glass changing in a window you already have? We replace sealed units too.
