Astragal Bar Entrance Doors
Traditional divided-light detailing combined with glazed entrance panels gives astragal bar entrance doors a period-inspired appearance suited to cottages, heritage-style homes and traditional properties. Astragal bars are applied to the glass surface and can be combined with matching spacers within the sealed unit to create added depth and shadow lines. You can choose diamond, square-grid, or bespoke layouts to suit the door proportions. We install and replace these doors with suitable glazing, secure hardware and carefully aligned bar detailing.

Astragal Bar Cornerless Doors
Large glazed areas with minimal visible framing create wide openings in astragal bar cornerless doors, whilst applied bar layouts introduce structured geometric detailing across the glass. Coordinating the bar pattern across adjoining panels is particularly important where the doors form one continuous visual elevation. Diamond, square grid and bespoke patterns can be configured to suit the opening and door design. Using carefully surveyed panels and accurately aligned decorative bar layouts, we install and replace cornerless doors with astragal bars to create a consistent and balanced finish across the full glazed area.

Multi-chambered uPVC frames combined with applied astragal bars provide period-inspired divided-light detailing with the low-maintenance characteristics of modern uPVC. Astragal bars can be colour-matched to the frame, with white, woodgrain and coloured finishes available based on the selected system. The bar width and pattern can be coordinated with the door proportions and glazing layout. Our in-house team installs and replaces uPVC doors with astragal bars, suitable sealed glazing, secure multipoint locking and carefully aligned decorative detailing.

Astragal Bar Composite Doors
Composite entrance doors combined with astragal bar glazing provide traditional divided-light detailing alongside the construction characteristics of a modern composite door. Applied bars can be coordinated across the glazed panel to create square grid, diamond or bespoke patterns, depending on the door design.

Astragal Bar Sliding Doors
Large glazed sliding panels combined with applied astragal bars create wide openings whilst introducing structured divided-light detailing across the closed doors. Bar patterns need to be carefully coordinated between adjoining sliding panels so the grid remains visually consistent when the doors are closed.

We install and replace sliding doors with astragal bars using compatible track systems, secure locking and accurately aligned decorative glazing.

What Our Happy Customers Say
Brilliant Service from Leon,Jack and Barry when they fitted my new front door. They were so helpful explaining the new lock and I am delighted with my door. My neighbours have commented on how nice it looks. A big “ thank you “ to the whole team at Bowalker Windows from sales to completion I have been very impressed and would certainly recommend this company to family and friends .
We have had a front door and side panel installed,Team Tim did a great job and were very professional and knowledgeable. Wouldn’t hesitate to recommend the company and this team to any one !
Simon and Brandon fitted our three windows in our garage > studio conversion and were great through the day. Arrived when they said they would, were very polite, respectful and pleasant people. Found answers to questions we didn’t realise about the installation and though we haven’t yet finished the project the windows are a very exciting and big step forward for us. Would recommend this company and this team without hesitation. Thank you!
Had a problem with our door which was installed 3 years ago - Bowalker - Dean - came to site within 24 hours and helped resolved- thank you ! Very pleased with professional and prompt service
Excellent service from a local independent company. Highly recommend.
I had replacement windows installed. Design and advice was good and cost was competitive. Installation was started in a good time to a good standard.
Bowalker have been incredibly helpful and provided me with extremely useful information about the windows and doors at a property I moved into, previously supplied by them. Great customer service, really recommend
Bowalker replaced all of our windows and patio doors in November. They are very efficient and got the job done in the pouring rain but did it quick and professionally. We had a couple of teething issues with the doors after completion and they did not hesitate to come out and rectify the issue. Excellent customer service and a friendly team. Would highly recommend
We had a total of 6 windows fitted at end of June 2025 (2 bathroom(frosted), 1 hallway,1 dining room and two big bay windows complete with 2 window boards). Took 5 days in total as bay windows were load bearing ,the window boards were not in warehouse so took extra time to arrive and fit , the silicone/mastic finish wasn’t great and they cut one end of a window board wrong , but after a telephone call a new team of fitters came out and rectified the mistakes of original fitters that we had noticed , a window pane had got scratched in delivery so they replaced that as well. This was a big job that entailed some mistakes but over time was rectified by bowalker windows by sending out another team of fitters to fix some minor mistakes of original fitters . We went on a recommendation from a work colleague who had used Bowalker windows in the past as were very good. Maybe just improve your fitters mastic silicone skills a bit more but is is an old house of 110 years and nothing is level in this house

Frequently Asked Questions
What are Astragal Bars for Doors?
Astragal bars for doors are decorative glazing bars fitted to glazed door panels to recreate the appearance of traditional divided-light glazing. They can create Georgian, diamond, square or bespoke patterns across a modern sealed glass unit without requiring each section to use a separate pane of glass. Astragal bars can be used with uPVC, aluminium, timber, steel and composite doors.
How Long Does Astragal Bar Installation Take?
Astragal bar door installation takes around 1 to 2 days for a standard residential replacement, depending on the door configuration, opening dimensions, frame condition and installation requirements. A straightforward French-door replacement may take around one day, whilst larger bifold, sliding or bespoke systems can require additional time for positioning, alignment and adjustment. Our in-house installers check the astragal bar layout, glazing, hardware and final door operation before completing the installation.
How Do You Clean Astragal Bars in Doors?
Clean astragal bars and glazed doors with warm water, mild detergent and a soft microfibre cloth, wiping gently around the bar edges and joints where dust and condensation residue can collect. Use a soft-bristled brush for corners and junctions between the bar and glazing surface, and avoid abrasive pads, solvent-based cleaners or harsh chemicals that could damage the bar finish, frame or sealed glazing unit. Clean sliding and bifold door tracks separately using a dry brush and damp cloth to remove debris and maintain smooth panel operation.
How Do You Choose the Right Astragal Bars for Doors for Your Home?
Choose the right astragal bars by considering the door style, glazing dimensions, property’s architectural period, preferred pattern, bar width and frame material. Georgian grids with evenly spaced horizontal and vertical bars suit period and traditional properties, diamond patterns complement cottages and rural homes, and bespoke geometric layouts can be configured to match existing decorative glazing or windows elsewhere on the elevation. During your consultation, we assess the door proportions and recommend a bar width, profile and configuration that complements the surrounding architecture.
What Astragal Bar Door Design Ideas Should You Consider for Your Home?
Consider astragal bar door design ideas such as Georgian grids for period properties, diamond patterns for cottages, square layouts for traditional homes and bespoke geometric designs for contemporary interiors or Crittall-inspired schemes. Astragal bars can be incorporated into entrance, French, bifold and sliding doors across uPVC, aluminium, timber and steel frames to create consistent decorative detailing throughout the property. Coordinating the bar layout and profile width with existing window astragal bars or leaded glazing can also create a unified decorative scheme across the full elevation.
What Guarantee Do You Provide for Astragal Bar Door Installation?
Bowalker provides a 10-year, insurance-backed guarantee on qualifying astragal bar installation and replacement work, giving you confidence in our workmanship. Our in-house installers manage each project from measurement through to final installation and inspection, ensuring accurate alignment and secure installation.
