Rockdoor are the most secure composite doors on the market. They combine the latest technologies into one to create a composite door that even the police cant get through. The main reason they are so secure is that these composite doors are made to measure. It starts with the inner frame of the door, this is made up of carbon fibre. Most composite door manufacturers buy door slabs and machine them down to get the desired size, so the strength gets compromised. With a Rockdoor, every door, no matter the width or height, has a custom inner frame of carbon fibre running all the way around the door slab. This provides great strength for essential fixing points such as locks and hinges. Next is the German engineered multi-point locking. These are made exclusively for Rockdoor by Winkhaus. A standard Rockdoor Ultimate comes with 2 hooks, one at the top and one at the bottom, as well as a shoot bolt. They can be upgraded to 3 or even 4 hooks. Each hook is made from a combination of brass and steel for the highest strength. The cylinders Rockdoor use are the best available, they are 3-star cylinders made by Avocet S-Glaze technology further improves upon the security. S-Glaze advantages are that security is increased as its impossible to get the glass out. 3mm high impact internal and external skins help protect your door from scratches and damage, but also add to the strength as they are very strong. The core of the Rockdoor is filled with an extremely high density foam.
Like the security, Rockdoor also top other composite doors greatly in thermal efficiency. The door slab is 50mm thick and all glass is argon-filled and double glazed. The glass is soft coated for increased thermal efficiency. When Rockdoor combines this with their S-Glaze technology and the carbon fibre inner frame, a lot of Rockdoor achieve an A++ energy rating. The best any composite door can be.
S-Glaze is Rockdoors own process and technology for encapsulating the glass directly inside the door during production, where most composite doors have a glazing cassette, which means the glass can be removed, Rockdoor does not use this method. This maximises security and the thermal efficiency is increased massively as the glass is locked into the door air tight so there is no air between the door or the outside.
Rockdoor feature a wide range of customisation. A Rockdoor can come in 13 different colours, and 9 of them can have colour matching frames too. Each door skin features Heat Shield Technology and has a very real-like woodgrain texture. You can mix and match internal and external door colours so you can be sure there will be a specification for you. They feature 5 different furniture colours, Black, Gold, Satin Chrome (Graphite), Polished Chrome and a Stainless Steel bar handle with Satin matching furniture.
You can tell how well insulated and efficient a Rockdoor is by how quiet it gets when closing the door. We have fitted over 1,000 of these composite doors and still to this day we get amazed by how a Rockdoor makes outside noise become so quiet. As most composite doors use a glazing cassette, they are not properly sealed like a Rockdoor is, and is one of the reasons they will never achieve the A++ energy rating a Rockdoor can achieve. Everything in this door from the inner frame, brilliant seals, and Rockdoors S-Glaze technology combined makes this door sound proof outside noise by a big margin. If you live on a noisy road then this door is perfect for you.
