Patio Doors

Patio doors are great for creating a dramatic impact with their wide, uninterrupted glass area.

patio doorsCoastline Windows can install two, three or four pane patio doors to suit your exact requirements.

Using the highest-quality, modern glazing techniques we can ensure that your glass patio doors are hard-wearing and stand up to the rough and tumble of active family life.

Our double glazing is also designed to be energy-efficient, reflecting heat back into the room on colder days but not allowing too much glare or heat to build-up on summer days.

An eight point high security locking system ensures that your patio doors – like all types of doors supplied by Coastline Windows - give you excellent protection.  

All the patio doors that Coastline Windows install are manufactured in line with the BSI’s exacting standards for operational strength and weather resistance.

Bringing your garden closer to your home, patio doors can make your room feel bigger and brighter than ever before.

The Q-Lon weatherseal  in our patio doors, which also features in our windows, will keep its shape year after year to maintain a weather-tight seal over many years and over a wide temperature range. It also absorbs noise pollution and resists mould, mildew and rot.

Our uPVC patio doors are made-to-measure and fitted to the highest standards. They are fully sealed, double glazed units to keep your home warm and cut out draughts.

Advanced glass technology and superior insulation reduces heat loss, helping you to reduce your carbon footprint as well as save money on energy bills.

Coastline Windows patio doors are also easy to clean and virtually maintenance-free. Just wipe down with a damp cloth every so often to keep your doors looking as good as new. All of our doors come with a ten-year guarantee – but you can also protect your investment and ensure smooth hassle-free operation by taking up our windows and doors MOT offer.

For other options, take a look at our French doors and bi-folding doors as well as our durable and beautiful front doors and back doors.
