OPERATION & MAINTENANCE

We offer industry leading products and although the maintenance required is minimal it is important that they are properly maintained on a regular basis. Our premium bi-folding doors, sliding doors & windows all need to be operated correctly as outlined below.

Lubricate moving parts reguarly

Keep all mechanical moving parts lubricated regularly. This includes hinges, multipoint locks, handles, the steel rollers in the bottom track and guide runners in the top track.
Lubricate using silicone spray or grease and wipe away any excess with a non-abrasive cloth, do not use WD40.

We also recommend that you fully open your doors at least once a month. This ensures all moving parts are lubricated and prevents any settlement within the products over the winter months.

Our aftersales department offers a maintenance pack which includes 1 x tube of premium quality glass cleaner, 1 x tube of silicone spray & a none-abrasive microfibre cloth for £17.00 including postage & packaging.

Keep the doors bottom tracks clear

Clear the doors bottom tracks of any debris and do not allow debris to build up in the track as this will affect the operation of the door. A build-up of debris can lead to a block in the drainage, causing water to come into the property. Use a small brush to loosen any debris from the track and use a vacuum cleaner with a thin attachment to collect.

Keep the powder coated profiles and gaskets clean

Use a light, soapy solution and a non-abrasive cloth to wipe dirt from the windows and doors. Avoid using an abrasive cloth such as a scouring pad as the windows and doors could scratch. Do not use washing up liquid, solvent based cleaning products or white spirit. In salt-water environments, the external surface of the windows and doors should be washed down with fresh water on a weekly basis as it is common for salt deposits to build up.

To keep gasket seals clean use a light, soapy solution and non-abrasive cloth to gently clean the seals & do not use solvent-based cleaning products.

OPENING BI-FOLDING DOORS WITH A MAIN TRAFFIC DOOR –  1. Insert the key and unlock door. 2. Open the main traffic door 180 degrees, ensuring the panel is fully engaged on the panel catch.  3. Turn the intermediate flat handle to the open position to release the shoot bolts. 4. Push the panel above the grab handle then slide the doors fully open, ensuring the traffic door remains on the panel catch.

CLOSING THE DOORS -1. Place your hand between the two doors closest to the wall and guide the doors along the track. 2. Once closed and positioned against the frame, use the grab handle to ensure the panel is positioned in the bottom track and rotate the intermediate flat handle into the locked position. 3. Release the main traffic door from panel catch by gently pulling away from the adjacent panel. Fully close and lock the door with the key.

sliding door operation

Lift and slide doors operate slightly differently to normal sliding doors, but the important tips are the same. Remember to always be careful not to trap your fingers in the doors when closing or operating them. Only use the handle to open and lock the door in place. Limit using the handle to slide the door and instead use the motion of the door panel to control its operation at all times. Ensure the doors do not slam into the side jamb when sliding closed. The tracks for our sliding doors are very deep so it’s crucially important that they are kept clear of debris.

Sliding Door Operation

Sliding doors are simple to use but these tips will ensure years of trouble free use. The door panels often weight nearly 200kg so use the doors momentum to open and close them and not the handle itself. Only use the handle to open and lock the door in place. When operating the sliding door ensure the panels do not slam into one each other.

We recommend sliding one panel at a time. If the door feels too heavy to close the door while sliding two panels at the same time, slide the middle panel individually from the inside, followed by the master door.

lift & slide tips to remember
