Going to swap my up and over garage for a roller electric one.
Dilemma is the shutter thickness to order.
The shutter slat is double skin aluminium filled with foam type
Insulation.The slats are available in 11. 15. 19 mm.This affects the cost of the door.
How do I justify spending more than necessary just by ordering the thickest.
Would it make much difference,could you feel it......help

Can't advise on the thickness but doubt you'd notice much difference in the slats?

Whatever you do though check the speed of the one that you eventually buy

Chap around the corner from me has one and its like watching paint dry when he operates it and its been like that from new

I have a pair of seceuroglide excel’s, very happy with them, would recommend to others.

You will not notice and difference, point to note is the thicker slat the more space is needed for roller.

It may be to do with opening width and wind pressure, mine is 19mm, but the door is 3.5metre wide. A narrower opening
could have thinner slats?

Thanks guys all useful comments and will help to make my mind up.

I fitted a Techentrup German door, it's 40mm thick and make an amazing difference when working in the garage on a cold day. Yes it's not cheap but it should last for a long time

Integral garage now converted to a bedroom, but the up n' over garage door is still on the front with 5 feet of storage space behind it. Can't comment on the thickness issue, but I'd say making certain the gaps around the edge of the door are properly draught proofed will make a massive difference to any heat "leaking" out of the garage.

There are generally three types of garage door. Up and Over, Roller and Sectional. Sectional is the one that are 4-6 sections that roll up and onto the ceiling and take up and lot of roof space. Roller just rolls up. Sectional can be upto about 40mm thick and offer the best insulation by far. Rollers can be upto about 19mm thick. If you have a standard Aluminium skinned Up and Over you will notice a difference between it and a insulated door.

When I built my extension I was going to put in a 40mm sectional door and ended up just reusing my original electric aluminium roller door. Because it cost nothing to move. However I am yet to experience a winter in the new garage.
