Sealtight Windows NE Ltd are proud to be Solidor suppliers, and offer a wide range of styles to suit any home. Unlike traditional foam-core composite doors, a Solidor is manufactured with a hardwood timber core, making it the most solid door available for your home in Darlington. This timber core and energy efficient double or triple glazed windows also improve the thermal performance and energy efficiency of your door in line with Solidor’s ‘Green Promise’ – environmentally friendly values that we at Sealtight Windows NE Ltd share.

Solidor provides a great compromise between style and strength in order to keep your home safe. They are more secure than traditional foam-core composite doors, as they are manufactured with high-quality materials and come installed with security systems such as the Avantis multipoint hook lock and a sleek and modern Solidor security hinge, which is incredibly robust and durable. Every Solidor is fitted with a revolutionary Ultion cylinder, which goes into ‘lockdown’ mode in the event of a potential break-in, ensuring that your home remains protected.

Not only will your Solidor be a durable and strong option for your home in Darlington, it will also create a stylish entryway into your home. We at Sealtight Windows NE Ltd offer a variety of options to make sure your Solidor blends seamlessly with your style.

Whether you’re looking for something traditional or contemporary – or even if you want to go for a luxury product to put the finishing touches on your dream home – Solidor provides composite doors to fit any style. They can also be specially altered into French doors or stable doors to further customise your design.
