At Grand Openings, we only work with the best. So if you’re looking for a composite door with unrivalled security and affordability, look no further Residor. The UK’s most secure GRP composite door comes with a thick GRP skin, making it double the thickness of the majority of doors on the market.


Residor doors are also extremely versatile too. To ensure they suit any home, doors are available in 16 different styles and come in white, red, green, blue and black and anthracite grey as standard. But if you’re looking for something a little different, Residor gives you the option to have ANY RAL colour, so you can have a door that’s truly bespoke to you.


Each Residor is fitted alongside its ground-breaking Ultion door lock, which features an Ultion cylinder to a high security multi point Era lock as standard, giving you extra peace of mind. Finally, all Residor doors are fitted with stainless steel Trojan hardware as standard. If a break-in occurs as a result of lock snapping, Ultion will give you £1,000.
