1. External glass sliding door installation – what’s involved

Surveys: Our technical surveyors will make a site visit to assess existing support lintels and floor levels, especially important with complex glazing designs, glass roofs and glazed corner structures.
Specialist equipment: We use glazing robots or automated glass vacuum lifters fitted with suction pads to manoeuvre huge sheets of glass up to 1000 kg in weight
Access: Sometimes delivery is challenging. That’s where cranes and spider or mini cranes come into play. Generally, the only thing that thwarts us is high wind, but that’s only temporary. We liaise with your builder to ensure everything is as smooth as possible on the day.
Expert teams: Our installation teams are not fazed by the trickiest locations and they’re one of the reasons why our customers recommend us.

2. sliding door maintenance – tips before you buy

How to make sure you get yourself a trouble-free sliding system:

– Tracks must be kept free of dirt and debris. Look for track design which features a guard to prevent ingress.
– Rollers can sometimes become worn and need replacing. A well-designed sliding door design with high quality components will ensure that this is an easy and accessible job.
– Large panes of glass are best given a coating which prevents sea salt or traffic pollutants from sticking fast – it makes routine cleaning quicker and easier.

3. Calculating the cost of a sliding door system – understanding your quotation

Bespoke sliding door designs are not standard, off the shelf products. Each system has specified frames, number of panels (fixed or moving), pane sizes and number of running tracks to suit its location – and all are factors in the overall cost.

A quotation will also include any extras such as self-cleaning coatings, integrated alarms, sound insulation as well as compatible blinds and awnings. It will also take into account installation costs.

4. Planning requirements for sliding doors

Permitted development allows changes to doors and windows, including the installation of sliding doors. It’s important to have a conversation with your builder about obtaining Building Regulations approval and check if there any local authority restrictions on your permitted development.

Flats, apartments, maisonettes and, of course, listed buildings, all need planning permission for sliding doors. We have years of experience working with past clients on these types of projects, and while we can’t arrange for your planning permission, we can offer advice and solutions to help with the success of your application.

5. Where to see sliding doors in action

Our showrooms are the best place to explore the look and feel of the ODC sliding door range. Take your time to browse the different designs, looking at colour charts and test the various opening configurations of our sliding door systems. It’s all part of getting the perfect glazing for your home.

6. Bifold doors, French doors and Crittall industrial look doors – alternatives to sliding doors for large glazed openings

Wood and aluminium composite bifold doors feature a wood frame with an aluminium exterior. The high quality aluminium shell offers excellent weather protection while the visible interior has the warm character of the wood. A slim sightline and impressive U-values add to the universal appeal of this door.

Wood bifold doors are thermally insulated timber external glass doors. They have an aluminium core – a multifunction insulating thermal break – covered with solid wood sections inside and out.

Aluminium double French doors or external doors are designed as rear or side doors for homes where aesthetics and security are essential throughout. Like sliding doors, French doors can be fully customised for seamless integration into a glass curtain wall or glass structure.

Crittall doors and black framed glass doors create the vibe of industrial lofts, characterful glazing for period homes and provide strong, individual design for new architecture. ODC Metro black frames and glazing bars customise sliding glass doors, transforming large areas of glass into smaller units.
