Enjoy stunning external views with our sliding patio doors

Get a Quote

One of the main selling points of patio doors is that they are mostly made up of high-quality glass. This ensures you can enjoy clear, uninterrupted views of your outside space. If you’re particularly proud of your garden and want to appreciate it from within your own home, patio doors are perfect for you. Large glazed areas also mean plenty of natural light can get into your home, ensuring it always feels bright and spacious.

A sliding patio door is not the only style of back door you can choose from. Bifold doors and french doors are both stylish solutions. But, which type of doors are best for you?

The benefits of sliding patio doors

Safe and secure sliding patio doors

At Emerald, we can use larger glass panes which don’t make your door any less secure. Our glass sliding doors are thermally toughened, making them incredibly difficult to break. We also installed an internal glazing bead so the glass panes cannot be removed from the outside, keeping your home safe and secure for the long term.

Thermally efficient sliding patio doors

We use a gap between the glass panes filled with argon gas, Low-E internal glazing, weather-resistant seals, and trickle ventilation to help retain the heat inside your home. Our sliding patio doors are also fully insulated with the door panel engaged into a channel of the outer frame to give draught resistance reducing those pesky energy bills at home.

High-Quality Sliding Patio Doors

Emerald offers high-quality sliding patio doors in uPVC and aluminium in various finishes so that you can find the perfect fit for your home.
