THE MOST SOPHISTICATED MANUFACTURING PROCESSES IN THE INDUSTRY


GRM windows was founded by Gareth Gambling In 1975. After installing high quality windows, selling to trade was the next step. His philosophy has always been to supply high quality windows at a competitive price.
 
To achieve this, his belief has always been to keep the service personal, whilst investing in top line machinery to produce the windows.
 
Richard Gambling Joined GRM in 1994 with a view to taking GRM forwards for the next 30 years.

Our factory has some of the most sophisticated manufacturing machine available to the industry. This enables GRM to produce windows with fast turn-around, very accurately and efficiently.

AV2 Automatic Multi Point Locking System
Upvc doors historically, have needed two operations to lock. Lift handle, turn key. This means that unless you ’lock’ your front door, the house would be insecure.  Now GRM are proud to offer the  AV2 Automatic Door Lock - an automatic system that requires no wiring or power supply.
 
Questions:
 
 Do the elderly and infirm have difficulites lifting handle levers to throw multi-point locks?
 
 Do some tenants forget to actually throw the hook/deadbolt, thus compromising security?
 
 I am unable to lock the door. Does this sound familiar?
 
 Would a slam shut multipoint locking system give great peace of mind?
 
If you have answered YES to these questions then the answer is the Winkhaus Cobra AV2 AUTOMATIC multipoint lock click here
