Hello everyone,

In our new building, I am planning a connected garage/workshop area for hobby purposes, i.e. in addition to the workshop equipment, bicycles, motorcycles, boats, or possibly a classic car later on should be accommodated there. Therefore, this area is planned within the insulated building envelope and is located in the basement of the house (ground-level accessible by car, as it is a hillside property). It is explicitly not intended for everyday cars, so the door will be opened only a few times a week accordingly (main access planned through the basement staircase with a smoke-tight fire protection door).

--> Which door or double-leaf door is suitable for my project and fulfills the following points:
- Clear interior dimensions in the open state at least: 2.3 m width and 1.95 m height
- "Reasonable" thermal insulation (so that this moderately heated area does not have excessive heat loss - target temperature in winter is at least 13-15° continuously). In this context, good tightness naturally also counts (no drafts, no holes through which insects etc. can enter).
- No high threshold, should withstand the load of a normal passenger car.
- Weather resistance
- Desirable but not mandatory: Good burglar protection (RC2). However, this could also be ensured by a suitably equipped door leading to the staircase (this would at least secure the residential building).
- Budget: €3000 material, preferably cheaper ;).

My thoughts so far:
Either a well-insulated sectional door, e.g., from the Hörmann LPU67 series. However, I am unsure whether these are really suitable for this project concerning airtightness (drafts, insects)? Which garage door (manufacturer, model) currently offers the best thermal insulation and tightness?
Second thought: A multipurpose double-leaf door such as the Hörmann D65-2 RC2. Here I suspect that these are only suitable as interior doors (I couldn’t find anything about this on the homepage spontaneously?) and especially regarding weather and rain tightness not good enough?

That turned out to be a bit lengthy – thanks for reading – now fire away with your ideas as well as input on the mentioned options!

Best regards MaytO
