Insulated Sectional Garage Doors, Bolton
Sectional garage doors are a strong choice when you want better insulation, dependable security, a cleaner modern look and smooth day-to-day operation from a door that opens vertically and parks neatly overhead.
Sectional Doors Make Sense When Performance Matters As Much As Looks
Are you looking to transform both the look of your home and how you use the space inside your garage? An insulated sectional garage door will do just that! Solidly built to withstand the rigours of everyday use, they feel secure, substantial, effortless and smooth in use. Insulated sectional garage doors are the preferred choice if your garage is integral or attached to your home. They also elevate the look of your home – every time you arrive home, you’ll appreciate an insulated sectional garage door’s good looks.
Better Insulation Saves Money for Garages That Need to Work Harder
Garages are often cold, draughty and uninviting places. If your garage is attached to your home, sits below a bedroom or is used as a home office or gym, keeping the garage space heated can be costly if you don’t have an insulated garage door. An insulated sectional garage door with 40mm thick insulated panels, all-round seals and a ‘U’ value of 1.38 W/m²K is designed to bring your garage back into your home.
A ‘U’ value gives the thermal performance of a typical sized complete garage door not just the panel (low values are good, high values are not!). Typical double-glazed window units have U-values between 1.2 and 3.0 W/m²K so an insulated sectional garage door compares very well! This not only saves you money on your energy bills by reducing heat loss, but creates a warmer, dryer and less draughty interior garage space. Understanding garage door U-Values and their impact on your energy savings can be confusing - Watch our U-Values video which helps you understand what they mean and how different garage doors perform.

Some garage doors are better at saving energy than others, so it's important if you use your garage as a workroom, hobby room or if it's under a bedroom. Teckentrup makes insulated garage doors that are very good at saving energy.
They have low U-values, which is the measure of how well something insulates. Low values are good, high values are not. These days, the average price of energy is around 25p an hour for a 1kW heater. Let's put our doors to the test.
We set up four identical garages to calculate how heat efficient each door is. The garage we modelled was typical, four metres square with a 2438 millimetre wide by 2286 millimetre high garage door or eight foot by seven foot six in old money.
We used an outside temperature of 10 degrees centigrade which, believe it or not, is the UK's average temperature over a year. Insulated roller garage door, typical U-value 5.2. Teckentrup insulated sectional garage door, typical U-value 1.38.
Teckentrup insulated side-hinged garage door, typical U-value 2.2. Up and over garage door, typical U-value 7.0. Four identical garages, four different doors with different insulating capabilities. Let's compare the cost of each door's heat loss over a year when keeping the garage at a cosy 20 degrees centigrade.
Insulated roller garage door, £665. Teckentrup insulated sectional garage door, £193. Teckentrup insulated side-hinged garage door, £279. Up and over garage door, £879. The Teckentrup insulated sectional garage door and insulated side-hinged garage door come out on top.
The savings comparisons are a real eye-opener. Up to £686 saved per year. It's not long before you'll have saved the entire cost of a Teckentrup garage door compared to other garage doors. Save energy, save money, and great doors too.
Choose the Teckentrup insulated sectional or insulated side-hinged garage door from Teckentrup.
Garage Door Safety and Security to Protect Your Family
Have a busy and bustling household? Use your garage for storage? Safe operation and effective security are important considerations when choosing a new garage door for your home. An insulated sectional garage door is designed to offer both.
Every insulated sectional garage door carries a CE/UKCA mark which ensures your door meets all current safety legislation - Never buy a garage door without this mark!
In-built garage door safety offers peace of mind - The control unit uses safety sensing technology to reverse instantly if an obstruction is detected and high-level concealed springs, finger pinch and hand protection at the side of the door ensures little hands can’t go where they shouldn’t.
Security is excellent too – A sectional garage doors’ solid build provides physical protection backed up by the motor which holds the door in place, pushing back with a 60kg force should an intruder attempt to force up the garage door.
