GRP skinned
To give great definition and long life performance DYNAMITE Doors use glass reinforced plastic skins. For keeping people safe, secure and protected against all weather conditions. It's used today to make the hulls of boats because its super-strong and has exceptional wind and water resistance. That's why we use it for our composite doors.
The average rainfall in the UK is between 700mm a year in East Anglia, and up to 3,000mm a year in the Scottish Highlands!* To make sure our doors are up to this demanding task they are tested in a pressurised chamber to stimulate gusting winds starting at 63 miles an hour and up to 80 miles an hour - that's stronger than a hurricane.
Then they are tested further by spraying two litres of water every minute directly at the door in their test chamber.

The Edge
The hinge edge of your door has a PVC edging. Then we cut through the edging so that whichever hinge you selected sits neatly inside the edge of your door.
To make the door super-strong, the lock edge has been fitted with a full length of 4mm thick, powder coated aluminium lock strip. Then your preferred lock sits flush inside your door.

Reglazable
Making a door to just hold the glass is easy. But have you ever thought about what happens if the glass unit breaks down in that composite door you fitted? You will want that door to have been a Door-Stop door.
Our unique and patented glazing cassette can be removed from the inside to let you simply change the glass and reuse the cassette. You won’t need a new door because it has been damaged whilst trying to follow impossible deglazing knacks and techniques! All of our doors are reglazable except for FD30s Fire Doors.

Sidepanels
Our GRP side panel gives loads of choice. You can choose from 7 different designs, in 10 colours, with dozens of glass options – but, uniquely you can have a choice of width. All of which can carry the letterbox. All this may sound simple, but only with Door-Stop!

Thirteen door colours
The door can be as individual as you like. Three new door colours; Poppy Red, Duck Egg Blue and Black Brown, have added to our existing ten; White, Black, Blue, Red, Green, Oak, Darkwood, Cream, Grey and Chartwell Green.
We also offer colour all round options, and 9 frame colours - white, mahogany, cherrywood, oak, white grain, brown–black, grey, cream and chartwell green - to compliment your new door colour. All of which can be configured with gold, chrome, black, white and contemporary hardware; it's easy to see how there are over 900 billion types of door.



Internal colour choice
Providing the composite door market with even more choice, we are pleased to announce the expansion of our product offering with a new option that allows customers to specify a colour on both sides of their chosen front door.
With the same stunning range of 13 colours to choose from, the new option allows customers to mix and match shades to suit the inside and outside of their home. One colour can be selected for the external side of the door and a completely different colour for the interior, allowing the door to truly reflect the homeowner’s personality and complement both the building’s character and internal design.
With the introduction of internal colour choice as standard you can offer your customers more choice without the hassle. Our internal colour offering is available across our full range of doors and delivered in 7 days.
