How do you open a sliding patio door?

Our sliding patio doors are designed to be easy to open but completely secure when shut. To open them, you just turn the handle (to release the closing mechanism) and slide the door open. The door sits on rollers, so it’s easy to use regardless of its size and weight. 

With AGS, one of our expert installers will always show you how to use your newly-fitted door correctly and ensure that you are completely satisfied with it before they leave.

How wide is a two panel sliding glass door?

If you’re thinking of installing sliding doors, it’s important to consider how wide an opening you have to fill. Usefully, sliding doors don’t have any swinging doors that take up space, with the drawback that only one half of the door can open at a time. The standard size for a patio door is around 1.8m (6ft) across, which would give you an opening of 90cm (3ft) out to your garden. At AGS we can custom-make sliding glass doors to any dimensions you like — from making the most of a small opening, right up to a set of statement glass doors that take up a whole wall. Why not contact us today for a free patio door quote?

What is a lift and slide patio door?

Lift and slide patio doors use a different mechanism to traditional sliding patio doors. Most sliding doors always stay on their sliding track, but a fully-closed lift and slide patio door “de-rails” when it’s fully closed. This provides a better seal, helping to prevent draughts. To open, you “lift and slide” — turn the handle and then lift the door slightly to place it back on the track. You can also lock the door in place at any point on the track – great for summer days and garden parties!

Are patio doors energy efficient?

The right patio doors can be extremely energy efficient; it all depends on the quality of the door. If you fit a double or triple-glazed door with a high-quality PVCu, timber or aluminium frame and a good seal then your patio doors should be highly energy efficient. At AGS, we manufacture and fit our patio doors ourselves to ensure they’re as energy efficient as possible. We select for A-rated glass with a low U-value; the lower its U-value, the less heat a window will allow to escape.

Are sliding patio doors easy to break into?

While sliding patio doors are mostly glass, at AGS we fit toughened glass as standard on all doors and windows below 800mm from floor height to give you even more security. We use sophisticated and secure locking mechanisms on all our exterior doors, helping you feel safe and comfortable in your home. For more information on the most secure options for your patio doors, talk to us today.

How much does a patio door cost?

The cost of patio doors can vary widely depending on the material we make them out of, their size, and the type of glass you choose. As a general rule, aluminium costs more than PVCu, larger doors are more expensive and double glazing is cheaper (though less-energy efficient) than triple glazing. Whatever your preferences, we strive to make sure all of our products are of the highest quality and are properly, professionally fitted.

Features and benefits

Guarantees you can depend on.

We have built up a great reputation over years of delivering a first class service and excellent products, all from our local, no nonsense all-about-you company.

From characteristic country cottages to contemporary town houses, we’re confident that our products will offer a style and finish to truly transform your home. Through constant innovation the quality, durability and security of our products is genuinely second to none. As a local company we are proud to offer British Standards BS7412/PAS24 for enhanced security.

We refuse to compromise on quality

Our windows are made from British Made, high quality MarinespecTM components, with up to 25 years anti corrosion. They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

State of the art fabrication for best quality

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices. Our loyal factory workers are well trained and take pride in their work, they really care about quality.  Our machines are maintained according to a rigorous servicing regime to keep them in top condition.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our homes energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your home warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.

The styles available are endless and the choices to suit your home are bigger than ever before. Traditional, contemporary or modern; our versatile window and door designs will create the look you want to complement and enhance your home.
