Composite Doors

In the past few years composite doors have managed to establish themselves as the most popular choice for homeowners. This is in part due to stylish options, colours and traditional look that can’t be matched by conventional UPVC doors. But with so many choices on the market, where do you start?

Fortunately, at Sandringham Windows Norfolk, you need look no further. All of our composite doors feature a 48mm door slab, with a solid timber hardwood core, paired with a five chamber thermally reinforced frame. Unlike inferior composite doors with a 44m foam core slab, this provides far superior strength.

Security like no other

The quality of our composite doors doesn’t just stob with the slab. All of our composite doors come with the Ultion key cylinder as standard.

The Ultion lock is one of the most secure cylinders on the market today. Meeting some the toughest security tests, it has achieved approval by the police, BSI and locksmiths.

Featuring an ultra dense molybdenum core the Ultion lock offers supreme security to your home. If that wasn’t enough the Ultion lock also has a £1,000 securty guarantee.
