When managing a workplace, warehouse or retail property, fire safety is non-negotiable. One essential element is ensuring your building is fitted with the right commercial fire doors. What makes them different from domestic doors? How do you select the right kind for your business? What Are Commercial Fire Doors? Commercial fire doors are purpose-built doors that resist fire and smoke for a specified period, typically FD30 (30 minutes) or FD60 (60 minutes). They offer protection to both people and property in high-risk or high-traffic environments, giving more time for safe evacuation and limiting damage.  Internal Doors offers fire doors rated to both FD30 and FD60 standards.  Where Should You Install Commercial Internal Fire Doors? The placement of commercial internal fire doors depends on your building’s usage, layout and fire risk. Some typical locations include: Stairwells and escape routes — vital for preventing fire from spreading between floors. Boiler rooms and kitchens — areas with heat-generating or potentially flammable equipment. Storage areas holding combustible materials. Between workshops or industrial production zones and office spaces. Internal Doors’ commercial fire door collection is specifically designed for internal use in these kinds of settings. What Materials Are Used in Commercial Fire Door Construction? To be effective and certified, a commercial fire door must be constructed from materials that meet certain standards. Key factors include: Core material: All commercial fire doors use an engineered solid core, often with materials like calcium silicate to resist fire impact. Thickness: Typical FD30 doors are 44 mm thick; FD60 are 54 mm thick. At Internal Doors we stock many doors around those thicknesses. Fire-rated accessories and hardware: Hinges, locks, intumescent seals, door frames and glazing all need matching fire ratings. Why Are Fire Doors Crucial for Businesses? Choosing the right doors is more than ticking a compliance box. The right commercial fire doors: Save lives, by delaying the spread of fire and giving occupants time to exit. Limit property damage and loss, and help protect critical business areas. Reduce liability and ensure compliance with UK regulations (e.g. Building Regulations, fire safety standards). Offer peace of mind for clients, staff, and insurers. When it comes to protecting your business premises, commercial fire doors are a vital investment. By understanding what fire rating you need (FD30 or FD60), where the doors will be installed, what materials and finishes are appropriate and ensuring correct installation and hardware, you can ensure both safety and compliance.

Oak doors remain one of the most popular choices for British homes, valued for their warmth, strength and timeless appeal. Whether you’ve chosen a solid oak model or an oak veneer alternative, knowing how to treat internal oak doors properly is essential. Correct care not only enhances their natural beauty but also ensures they last for decades. Why Should Internal Oak Doors Be Treated? While oak is a durable hardwood, untreated doors are susceptible to swelling, cracking and fading over time. Central heating, humidity and everyday wear all take their toll. Treatment creates a protective barrier, helping the door withstand fluctuations in temperature and moisture while retaining its elegant finish. If you’re investing in new internal oak doors, regular treatment is the key to keeping them looking as good as the day they were fitted. How to Treat Internal Oak Doors Step by Step Start by preparing the door surface. Remove any dust or dirt, then lightly sand with fine-grit paper. Smooth imperfections and open the wood’s pores. Wipe away all residue before applying your chosen finish. For internal wood treatment, we recommend Hardwax and Osmo oils.  Always apply in thin, even coats using a lint-free cloth or quality brush. Let each coat dry fully before applying the next. This ensures the finish bonds correctly, creating a protective and attractive layer. How to Treat Oak Veneer Internal Doors If you’re wondering how to treat oak veneer internal doors, the process is similar but requires more care. The veneer layer is much thinner than solid oak, so avoid heavy sanding. A light buffing is sufficient before applying a water-based varnish or specialist veneer oil. These finishes protect without overwhelming the natural look of the veneer. Our collection of oak veneer internal doors provides an affordable way to enjoy the beauty of oak while still benefiting from a protective finish. What Mistakes Should Be Avoided? A common error is leaving edges untreated. Even hidden edges, such as the top and bottom of the door, should be sealed to prevent moisture seeping in. Another mistake is using wax or silicone-based polishes, which can break down protective layers and make future treatments difficult. How Often Should You Re-Treat Oak Doors? Most doors need retreating every two to three years, though doors in kitchens, bathrooms or high-traffic areas may need attention sooner. The key is to check regularly: if the surface looks dull, patchy or dry, it’s time for a new coat. Complete the Look with Hardware Once treated, consider how your accessories complement the finish. Our range of door handles and ironmongery includes everything from classic brass levers to contemporary chrome designs, ensuring your oak doors make a statement in any setting. Where to Find Quality Oak Doors If you’re planning to upgrade your interiors, explore our wide range of internal oak doors and oak veneer doors. With the right treatment and a little care, these doors will provide lasting elegance for years to come.

Period homes are full of charm, but bringing them up to modern safety standards can feel like a challenge. If you’re considering internal Victorian or period fire doors, this guide will help you retain character without compromising compliance. Why Choose Victorian or Period Fire Doors? Victorian and Edwardian houses are celebrated for their ornate style: panelled doors, intricate mouldings and period glazing all help define that heritage look. However, many original doors in period homes do not meet today’s fire safety requirements. Installing Victorian fire doors or period-style fire doors means you get: The look and feel of traditional design Modern fire resistance (typically FD30) Compliance with UK safety regulations and peace of mind Internal Doors offers a Fire Victorian Doors range, all FD30 rated, so you can preserve your home's period aesthetics while staying safe. What Do Victorian Fire Doors Look Like? Classic Victorian-style doors have several defining features including panelled design. Typically four or six panels, often with raised or moulded profiles.  Can You Get Glazed Victorian Fire Doors? Yes, glazing is a popular way to retain light flow in older homes, especially in Victorian terraced or semi-detached houses where internal corridors can be dark. Important considerations: The glass must be fire-rated (i.e. tested to withstand heat, maintain integrity, resist smoke) rather than regular float glass. At Internal Doors we offer glazed doors with FD30 fire-rated glazing. Framing, hinges and seals around the glazed panels must also be fire-certified. So a Victorian glazed fire door can give you period aesthetics and safety, provided all components are compliant. What About Edwardian Style Fire Doors? Edwardian style tends to be a little simpler than Victorian: cleaner, more symmetrical panel layouts less ornate mouldings and less carving sometimes flatter panels, or simpler glazing patterns Edwardian style fire doors are great if you want a period feel without a heavy decorative look. They often blend more easily with modern interiors while still satisfying fire door regulations. Do Period Fire Doors Comply with Safety Standards? Absolutely, but only if they are properly specified and installed. Internal Doors’ fire door range is built with FD30 and FD60 fire ratings. Remember: even a beautifully styled fire door loses effectiveness if fitted wrongly, or if non-rated glass/seals/hardware are used. Shop Internal Doors’ Victorian Fire Doors If you own a period home and love the Victorian or Edwardian style, you don’t have to choose between beauty and safety. By selecting period fire doors that are properly built, using fire-rated cores, accessories and hardware, you can retain architectural character and comply with UK fire door regulations.
