    Foam Filled vs Timber

  • There is a common misconception that a timber door must be superior in quality when compared to a foam-filled composite door. However, with excellent weatherproofing, sound insulation, durability, security and being less prone to warp, a Hallmark foam filled door with a 10-year warranty makes it a no brainier. One of the main reasons to choose a foam-filled composite door leads onto our next point. Thermal efficiency.Online door designerGreen Thermally Efficient Composite Door                                                                                                                                                                                                                              Hallmark

    Thermal Energy Efficiency

  • A thermally efficient composite door can help keep the heat in and keep the cold out and could save you money every month on your energy bills. Studies show that a Hallmark composite door is up to 17% more thermally efficient than a 44mm timber panelled door and 19% more thermally efficient than a 48mm solid timber core composite door.Online door designer

    High Security

  • When choosing a new front door one of the biggest concerns is security. Ensuring you, your family and your possessions are safe. A Hallmark composite door set has proven ability to achieve PAS24:2016, the industry’s enhanced security standard, a prerequisite in attaining certification to Secured by Design a police initiative to protect against unlawful intrusion.What this means is that we can manufacture a door to meet industry accreditations without compromising on the stunning design of the door.SBD, UKAS, DOC Q BM Trada Fire DoorOnline door designer

    Not All Doors Are Made Equal


  • It can be easy to think that a door is a door no matter where it is acquired from. But like a mobile phone, car or even a loaf of bread the components it is made from make a big difference.We aren’t interested in a race to the bottom, to squeeze prices and reduce the quality of our products. What we are interested in is manufacturing a quality bespoke composite door that stands the test of time and looks great.Our doors as standard come with steel reinforced outer frame, fully adjustable hinges, aluminium edge banding, multi-point locking systems and impact resistant GRP skin.(GRP – Glass reinforced plastic).

    Composite Door Wood Grain

    Stunning Woodgrain

  • So let’s talk about that outer skin. That’s what people in the street see from the outside and what you and your family see from the inside. So it’s important that it looks great! As stated in the previous point, not all doors are the same.Take a look down your street and you will see that the woodgrain effect on each door is completely different and some look much better than others.This is where a Hallmark door stands out and it is because of our woodgrain effect. It is a natural and authentic woodgrain based on an American Ash tree.One of the biggest compliments our doors receive is just how good they look. Don’t just take our word for it take look at our customer gallery.
