DOORS FOR SECURITY

HIGH QUALITY STANDARD

Unique structure door consisting of metal profiles and sheets brings out all the difference. Made from steel and dressed in wood – EDM, wood veneer, UMIDAX or painted metal finishes so nobody can say that it’s a high security door. Mineral wool is placed inside – it gives incredible noise isolation (44db) and thermal insulation (1.2W/m2K) qualities.

Knight’s Mark security doors comes with a three directional locking system as standard. You can have an optional security door chain (for unwanted forced entry), additional door bolts or additional anti-drill lock upon request. Door leaf construction is created from closed metal sections and 1.5 mm (can be thicker, depending on the level of security you choose from) steel sheet from outside.

Security doors have been acknowledged with various certificates. They been tested against a push force of up to 1040kg (small car weight) and various break in tools – axes, hammers, chisels, screwdrivers, crowbars and drills! If the security doors are ordered with side/top windows – it would be triple glazed as standard and most importantly the glazing would be laminated, specially treated and toughened for security reasons.

If you need an extremely high level of safety we also offer ‘Fortress’ level security doors which can be made bullet proof and (or) blast proof. Security shop front windows (for any high street shops that has valuables kept overnight), panic rooms or safe rooms can be quoted as well.

Great customer service and after ordering double glazed sash windows they were installed on time and could not be happier with the quality of them and the workmanship. The cost was very reasonable and I would highly recommend this company for products and great service. Many thanks to all staff.

I cannot praise Knightsmark highly enough. From start to finish they were excellent. Mantas and his team spoke to us at great length, spending time to understand what we wanted and offering suggestions which we really appreciated.We then received detailed plans and had a site visit. After having the door on order we were kept up to date regularly and were supplied with a photo of our door in production.The fitting team were proficient and friendly, making sure we were happy prior to signing off. Given we are renovating, they managed to still make it look like a really professional finish, better than expected.We easily have the best house on the street. Thank you Knightsmark!

Being a general contractor, we often deal with various doors and windows suppliers. 4 years ago we were lucky enough to collaborate with Knight's Mark on a project. Since then we have appointed them on almost every project.Their quality is second to none and their quotes are transparent and highly competitive.I can't praise them highly enough with Mantas and Dan going above and beyond to ensure that every aspect and minor details are explained and followed by their factory to ensure the highest standard of finishing quality for their products.

Excellent product and service.We bought a new front door. Time from order to delivery was exactly as promised. Quality of the product is superb - far superior to all the others we looked at. Also very impressed with the standard of workmanship of the Installation team. Old door taken out and new door installed with virtually no damage to the surrounding area whatsoever.Highly recommended.

Just had my new door installed and I could not be happier. It's beautiful. The service provided by Knight's Mark security door was great. I was contacted a day before the estimated lead time and the door was installed the following week. The fitters were polite, quick and left the house clean. Thank you!!
