External door for:
> Basements
> Heated outbuildings
> Garages with direct access to the house

Thanks to the door leaf with thermal break, the security door KSI Thermo46 offers the best thermal insulation and reduces the risk of condensation forming in heated rooms in contrast to a steel door. The break-in-resistant RC 2 security equipment means you can also feel secure  in your home. We recommend using this quality door as an external door for basements, outbuildings and garages.

The security door KSI Thermo46 provides excellent thermal insulation thanks to the door leaf filled with PU rigid foam; door leaf, frame and threshold all come with a thermal break. The door also features double seals on all four sides. With all  of this, the KSI Thermo46 has a thermal insulation value usually only found in entrance doors.

Security as standard

Basement and side doors are often weak spots when it comes to security. In this respect, the KSI Thermo46 offers the best equipment as well: 2 conical swing bolts and 2 additional security bolts and 1 lock bolt engage in the frame’s lock plate and firmly pull the door shut. 3 further security bolts and 3 guide rollers on the hinge side make it practically impossible to force the door open.

Hörmann products are manufactured to the highest quality standards and leave our factory only after rigorous quality testing. However, if you should have grounds for complaint, this section tells you what our door warranty offers, and how to go about making your claim.

In the unlikely event of a warranty claim becoming necessary, please contact the dealer or distributor who originally supplied your garage door. Your dealer should then supply details of the claim, together with a copy of the warranty card provided with the door and proof of purchase to the Product Services Department at Hörmann (UK) Ltd. To enable your claim under warranty to be processed as quickly as possible, you should provide the following details:

1 Your name, address and telephone number

2 Original invoice with date of purchase

3 Product description/door type and product number

4 Description of defect

An assessment of the claim will then be made. This may require Hörmann to inspect the product in-situ. In the event that there is no legitimate warranty claim under the terms specified herein, you may be liable for the costs of the inspection visit. We strongly recommend that you take note of the care and usage instructions displayed on the stickers on the back of your garage door, and on the page opposite, and that you follow these instructions throughout.

User Information/Care

Finish - Steel Doors

The coating process applied to the door and chassis is environmentally friendly. Minor scratches or marks are not covered under the conditions of our warranty and should be repaired immediately to prevent corrosion and deterioration of the panel. Corrosive substances such as acids, alkalines, and salts, etc. should be cleaned from the door immediately; failure to do so will result in deterioration of the finish, which will not be covered under our warranty. Should deterioration of the finish start to occur you will need to repaint your door immediately. Prepare the surface lightly with wet and dry. Then treat with solvent based 2 pack epoxy wash primer and a normal commercial paint (cellulose paint must not be used). Hörmann steel doors are a finished product. They do not require re-painting on site. They are however not immune to damage, which can occur at any stage of the handling of the product from factory to site.

Finish - Timber Doors

Timber panels are coated with a neutralising base-stain. Doors must be stored upright, under cover, with wrapping intact, until wrapping is removed. As soon as the door is unwrapped, one coat of a good quality basecoat primer must be applied to both sides of the door. Immediately after installation, your timber doors require a further two coats of a good quality exterior wood finish on both sides. Initial application and periodic treatment should be carried out strictly in accordance with the woodstain manufacturer's instructions. Failure to follow these instructions will result in early deterioration of the timber panel.

Finish - GRP Doors

GRP door panels should periodically washed down using water. This should be done more frequently if fitted near the sea. Bird droppings will bleach the finish on GRP. and should be removed using water as soon as possible. GRP doors should not be painted over.

Paint Finish - Steel Doors

Minor surface damage can easily be repaired using touch up sprays or sticks without invalidating warranties.
