Which Slat Size? 55mm or 77mm

Chartwell green roller garage door with 55mm slat size.

Would 55mm or 77mm slats be best for your garage door?

All our doors feature double skinned aluminium slats, filled with a special foam for insulation.

Our diamond doors are all supplied with 77mm slats, however for gold and silver doors there is a choice of two slat sizes, 55mm or 77mm.

So what determines the right choice of slat size? Would 55mm or 77mm be best for your door?

We would be happy to run through the choices for you when we carry out the survey at your home, but here are the factors to consider.

Door Size

The size of your door opening may well determine the size of slats that is the most suitable. 55mm slats are able to fit openings up to 7’7″ (2310mm) wide and 7’6″ (2285mm) high, any wider or higher and 77mm slats are required because of their enhanced rigidity. 77mm slats are able to fit large openings up to 16′ (4875mm) wide.

Garage Space

All of our roller doors utilise garage space more efficiently than traditional garage doors, freeing up extra space immediately inside the garage and along the walls. The motor housing of a 55mm slat door is more compact, allowing for greater head height in some garages.

Insulation & Security

Another factor to consider is the thickness of the slats. 77mm slats are around twice as thick as 55mm slats. This leads to improved rigidity. This is one of the reasons our ultra secure, diamond door comes only with 77mm slats. Along with the increased strength comes better insulating qualities, so less heat loss and better sound proofing.

Colour Choices

All our doors are available in a wide range of standard colours, and a custom colour can even be prepared. There are also some wood effect laminate finishes and some paint colours that are exclusive to 77mm slats.

Cost

An important factor is cost. Put simply, 55mm slats cost less than 77mm slats, so when a particular opening size offers a choice between the slat sizes it may be that budget is a determining factor. Either way, you can be sure that any door we supply is built to last, fit for purpose and meets UKCA standards.

Fantastic company.

Wanted to use a local independent company for my garage doors. Had been to the usual franchise companies and it was ok but felt like a production line.

These guys were so knowledgeable, helpful and attention to detail was second to none.

I’ll admit they were slightly more expensive than the franchise but literally only a by a small amount and I felt that was fair for the high level of service.

The job was done in less than a day and they left everything neat and tidy and gave me a lesson on the workings etc.

Highly recommend!

I have used the service where Sam came to us for giving the quote, unlike others he has made me aware of drain plate in the way at the bottom and also suggested alternative not to loose much width as it’s already very narrow. Once the quote is done and deposit paid , communication is very good about when the door will be installed and done excellent job. I will ask anyone to look no where else.
