Hello,
we are deciding between two wooden front doors.
I find it difficult to compare the offers. I hope you can help me evaluate many of the features mentioned and possibly even compare the offers.
I am mainly interested in the major differences.
Both offers look almost identical and can be considered equivalent in terms of quality.
Both offers include measuring, delivery, and installation.
Offer 1:
- 78mm (3 inches) thick Meranti wood
- Triple-coated with Sikkens white paint
- Triple-pane insulated glass
- Main door leaf with a three-point locking system "AS 2600" with 2 round bolts and 2 hook bolts in separate side boxes
- Bottom seal with a stop strip
- Sealing toward the masonry on both inside and outside without internal fitting strips
- Cover shell supplied and installed for mounting the door within the insulation layer of the masonry / facing brick
- Exterior pull handle
- Stainless steel rose handle set, consisting of an inside handle welded at the mitre and an exterior security escutcheon with cylinder pull protection
- Hinge side security fittings
- Mechanically self-locking front door lock, GU Security automatic
- Door U-value is 1.215 W/m²K
Offer 2:
- Version IV88
- Profile 4 with 88mm (3.5 inches) construction depth, Red Grandis wood FSC certified +500kg; 4-layer laminated, 88mm (3.5 inches) thick
- Door leaf built in frame construction with vertically continuous, adjustable anti-warp reinforcement on the lock side
- Surface finished with environmentally friendly water-based paints
- 5-point locking system with bolts and pivot hooks made of hardened steel
- Quiet latch for silent door closing
- Continuous locking strip in the frame as counterpart to the lock, made from a steel U-profile integrated in the frame
- Four heavy-duty, 3D adjustable concealed hinges for easy on-site adjustment
- Lock faceplate, locking strip, and hinges included
- Thermal break aluminum threshold, EV 1 anodized
- Triple-pane insulating glass with a U-value of 0.7 W/m²K as clear glass
- Thermally insulated core made of 45mm (1.8 inches) sandwich panel with internal and external 12mm (0.5 inches) plywood reinforcements and profiled edge
- High-quality silicone seal running continuously on all four sides in the door leaf frame, lying flat on the leaf overlap
- As IV88 design now: double silicone seal all around the leaf
- Additional three-sided seal on the outer frame
- Bottom of the door leaf with a brush seal to protect against driving rain
- As IV88 design now: bottom with an additional large brush seal for improved rain protection
- Overall door U-value approximately 1.1 W/m²K
- Front door pull handle
- Inner handle rose with PZ mount and core pull protection
- Threshold extension made of 40mm (1.6 inches) SB phonotherm panel, 170mm (7 inches) high
- Automatic lock with bolt and pivot hook; the pivot hook can be consciously locked with the key
My assessment:
- Offer 2 (originally only 68mm (2.7 inches) thick with a total U-value of 1.3 W/m²K, now adapted as IV88 version) is 10mm (0.4 inches) thicker than Offer 1.
- The U-value in Offer 2 is 0.115 W/m²K better
- Both wood types are comparable; Meranti is probably somewhat more sustainable
For the rest, I’m unsure. Is there anything significant missing in one offer that the other already has? Is something missing in both? What stands out as particularly good compared to the other offer?
Thank you very much for your help.

I finally decided on the more expensive door.
It was obviously also a gut feeling. I flipped a coin, didn’t like the result, so I went with the other option, which was the more expensive door.
I guess the better feeling mainly comes from
- slightly better features
- they actually invented the door
- original appearance with all the details, not just a replica based on photos
The price is high, but so far it hasn’t hurt.
Additionally, I’ve found that most suppliers (in any field, not just front doors) usually agree to a 2-3% discount.
