REWORD - Which Garage Doors Give the Best Insulation?
The 3 best garage door types for insulation in order of performance are:
There are quite a few factors to consider here if your expectations are very high for insulation but some basic advice is easy to explain for most requirements.
The first thing to remember is to make sure that if you require a specific 'U' value (measurement of insulation) achieving for your garage then you need the 'installed' 'U' value and not the quoted value of just the panel alone, this can be very misleading, so beware.
There are some good round the corner doors and also insulated sliding doors with excellent insulated panels too, but for mainstream garage doors we are looking only at the 3 above as a comparison.
Insulated Sectional Garage Door
This type of door can be obtained in 40-67mm double skinned steel door panel sections with a foam core insulation. As the sectional door operated in a vertical plane the panels can benefit from rubber weather seals all around the fixing frame adding to the weather protection properties of this door. The only way however to get the full benefit of an insulated sectional door is to install the door BEHIND the structural opening so the door panels overlap the garage piers and lintel effectively giving a 'thermal break' and continuing the insulation offered by the garage walls itself.
Each panel on a good quality sectional door will have a rubber seal embedded in each of the profile joint sections to give the best possible seal between the individual panels and combined with seals on all sides including a large seal on the bottom panel you can achieve the best U value if installed correctly. Additional seals are now also available on Hormann LPU42 and LPU67 doors to increase insulation further by up to 15%.
Insulated Side Hinged Doors
Side hinged doors have always been capable of offering high levels of insulation, just think about a freezer door, what is it? hinged of course...
Up until recent years in the UK no manufacturer had put in the effort of a double skinned, foam filled steel door set with rubber seals on a rebates edge all round. With a bottom edge threshold also with a seal built in you stand a chance here of a pair of large garage doors effectively sealing an opening very well indeed.
There are the Carteck Side Hinged doors and they are all made to order with an aluminium fixing sub frame included and high quality stainless steel furniture. We also offer our own extensive range of GDO insulated hinged doors in 20mm or 51mm panels.
Insulated Roller Garage Doors
The term ‘insulated roller door’ is used to generically describe most aluminium roller garage doors sold in the UK. As we make no apologies in constantly reminding people with roller garage doors that you really do only get what you pay for then you have to remember the same with insulation properties on these doors.
A good quality foam filled aluminium roller door will give good levels of insulation if installed behind the structural opening like the sectional door does. A cheap, poorly constructed double skinned roller door using inferior aluminium slats will not give much insulation and worse still will probably give you all sorts of headaches with rattling and motor problems - enough said, again!!
A roller door by its very nature is difficult to get a proper 'U' value for once installed as technically there is a gap, albeit small, between every slat and there are about 21 slats in the average height door. Install the door behind and add a full hood and you will definitely feel the benefits in the winter months however. Good sized guides and slats with a thickness of about 20mm is about as good as you will get for a domestic garage door.
Take a look at the Seceuroglide Roller Doors for one of the best roller doors in the UK.
We have an extensive, own branded range with our GDO ROLL77 electric roller doors.
The Hormann Rollmatic range is also a winner.
