DGU’s are usually ordered the next working day from the customers confirmed order date.

RPS Will contact you when your DGU’s are collected from the factory to arrange a suitable time and date with you for fitting.

DGU are guaranteed for 10 years from misting up. Your DGU’s are the best quality available and are sealed with BOSTIK 5000™ hot melt (190°C) butyl sealant.

They fully comply with both the European standard EN1279 parts 2,3,4 and 6 and the US/Canadian standard ASTM E2190.

Breakages or cracks in glass are guaranteed for 14 days from installation and scratches or marks must be reported within 48 hours of the installation to be replaced for free. Handles, hinges and locks are guaranteed for 12 months and any defects (marks or scratches) must be reported within 48 hours of fitting to get replaced for free.

DGU’s often mist up due to cracked or damaged sealant which allows air inside the seal and between the glass panes. This air condenses and then creates mist. Many older DGU’s have a 2 part sealant (brown/purple or grey) which is now at the end of life.

A swiggle strip is black and bumpy, this could also have been used. The swiggle strip incorporates the sealant and spacer, thereby removing the trapped air at DGU manufacture. However, swiggle strips are affected by UV and the majority are now breaking down. The main reason a modern DGU fails is due to the fitting. If both glass panes are not packed on level glazing packers then one side may slip and break the seal. The damage may not show for a few years but if fitted correctly, a quality DGU should not break down and mist up.

The majority of doors and side opening windows drop due to poor fitting of the DGU’s in to the frames. This is more often noticeable on doors. PVC doors are heavy due to the steel reinforcement inside the section; the DGU’s are also heavy. The door sash has to be packed on the DGU’s with the correct glazing packers and in the correct way.

Adjusting hinges will not fix a dropped door and be the cause of other subsequent issues. The door or window must be toe and heeled to the correct height and the lock must be inline and even to prevent these issues. Please do ask your RPS fitter for more information at the time of installation.

RPS prides itself on only using the best quality materials and is proud of its reputation and workmanship. RPS encourages its customers to watch the installation, so explanations can be made at time of fitting or repair, so the customer understands any reasons for original failure and potential actions to prevent reoccurrence.

Repeat customers and recommendations are important to RPS and we do ask if you can leave a review on our Google business listing. Additionally, the RPS webpage www.rpsgdr.co.uk has a video section explaining common reasons why doos and windows often fail, plus a maintenance video illustrating how to care correctly for your doors and windows.

RPS recommends GT85 to maintain all the moving parts except the keyways. Please only use graphite powder in the keyways as explained and demonstrated in the maintenance video.
