Certified Safety Glass
Our glazed fire-rated doors use toughened glass engineered to meet strict UK building regulations, protecting your space without sacrificing light. Every pane undergoes rigorous testing to satisfy current safety standards:
Fire resistance: Toughened materials hold structural integrity under intense heat to block smoke and flame spread.
Impact protection: Strengthened glass panels prevent shattering on heavy contact, keeping high-traffic passageways safe.
Verified compliance: Clear stamp markings on the glass confirm full adherence to UK fire and safety codes.
Premium Finishes
We offer a selection of high-quality wood-veneered fire doors using real timber materials designed to elevate your room’s style. Choose from two distinctive finish options that best reflect your interior design scheme:
Oak-veneer fire doors: Highlight prominent natural grain patterns that bring warmth and traditional durability to busy hallways.
Walnut-veneer fire doors: Display rich, dark tones that add a clean, contemporary edge to modern living spaces.
Note: Please remember that any grain/veneer is “real” and cannot be a complete mirror image unless you decide to request book-matched veneers. This would be considered a bespoke fire door pair.
Glazed Fire Door Sizes
We supply several size options to suit your interior layout and doorway style, including:
1981 mm x 1220 mm: Fits standard double openings, perfect for enhancing light flow in compact hallways.
1981 mm x 1372 mm: Adds extra clearance for wider passageways while keeping proportion across traditional door frames.
1981 mm x 1524 mm: Ideal for mid-sized connecting rooms, creating an open-plan feel without sacrificing safety.
1981 mm x 1676 mm: Provides grand entrance dimensions to maximise interior light impact in larger living spaces.

How do double glazed fire doors improve safety?
Double glazed fire doors help enhance safety by combining fire-resistant glass, expanding intumescent seals and certified frames into a complete protective system. Standard double glazing cracks quickly under heat, but fire-rated glazed doors are tested to withstand extreme temperatures for 30 to 60 minutes.
These specially designed doors deliver fire safety in three ways:
Fire and smoke containment: Heat-resistant glass panes and expanding seals block toxic smoke and flames from spreading between rooms.
Emergency escape routes: By slowing heat transfer across busy areas, these modern internal doors keep corridors safe for evacuation.
Guaranteed regulatory compliance: Full system testing ensures your installation meets strict UK building regulations for reliable fire protection.
Where are glazed internal fire doors typically installed?
Our glazed fire door pairs are fitted across high-traffic zones and key partition walls to maintain visibility and light flow through these primary areas:
Stairwells and corridors: Keep main exit routes safe while maintaining clear sightlines during an emergency.
Offices and commercial buildings: Divides busy workspaces into fire compartments without blocking daylight or feeling enclosed.
Public spaces and domestic partitions: Separates kitchens, integral garages or high-traffic communal zones from main living spaces.
Note: While we supply a wide range of glazed fire-rated internal door options, we do not offer installation services.
What should I know before buying double fire doors?
Before ordering internal glazed fire door pairs, review these important certification and fitting guidelines to ensure they suit your project requirements:
Single-leaf certification: Fire test certificates cover individual leaves. Always confirm with your fire officer, architect or building control before installation.
No central rebating: Do not rebate where the doors meet in the middle, as altering the edges voids compliance.
Hardware and fittings: Verify that all associated fittings, including hinges, latches and seals, meet your required fire rating approvals.
Visual representation: Product photos show how doors look once fitted. Because these items are tailored to order, they are non-refundable.
Do fire doors need maintenance?
Yes. Just like testing a smoke alarm battery or checking a fire extinguisher, fire doors require regular maintenance to ensure they function properly during an emergency. Everyday use causes minor alterations to the door and its frame, which can compromise fire performance if left unchecked.
Under Article 17 of the Regulatory Reform (Fire Safety) Order 2005 (FSO), keeping fire-resisting doors adequately maintained is a strict legal requirement for all non-domestic buildings. Regular inspections identify defects early so they can be repaired quickly, protecting occupants and ensuring full legal compliance.
