Frequently asked questions about the External doors category
External doors — what are they and what are they used for?
External doors — are entrance doors for houses or apartments that provide security, thermal and sound insulation, and aesthetic frontage. Our range includes steel, wooden and composite doors, glazed options and common sizes such as 9x21 and 10x21.
What types of external doors are there and how do steel, wooden and composite models differ?
Steel doors provide high security and durability, wooden doors offer better aesthetics and natural insulation, composite doors combine steel core with decorative cladding for a balance of safety and looks. Our range offers different panel thicknesses, insulation and finishes.
Are external doors with glazing suitable for a private house and what types of glass inserts exist?
Glazed doors are suitable for private houses to increase daylight; options include frosted, decorative or safety-tempered glass and insulated glass units to preserve thermal performance and security. Frames include seals and reinforcements to prevent drafts.
What standard sizes (e.g. 9x21, 10x21) are in the catalogue and how to choose the correct one?
The catalogue includes standard sizes such as 9x21 and 10x21 and frame options like 4x21. Measure the opening width and height, allow clearance for the frame and trims, and choose a door that leaves space for installation and seals.
PVC external doors — what are the advantages and disadvantages?
PVC doors resist moisture and corrosion, require minimal maintenance and come in many colours; however they are usually less burglary-resistant than steel doors and lack the natural look of wooden doors. Suitable where low maintenance is key.
Do external doors require a separate frame/fanlight and what frame options exist (e.g. OPUS S-1)?
Many doors require a frame or fanlight for secure fitting and insulation; options include frames like OPUS S-1 4x21 in white or black. The frame ensures proper sealing and correct door alignment.
What hardware and locks are best for an external door?
Choose certified cylinder or multi-point locks with anti-burglary features and sturdy external hardware. Ensure hinges have bearings and that seals are included to protect against cold and moisture.
How do external doors for apartments differ from those for private houses?
Apartment doors emphasise compactness, sound and thermal insulation and sometimes fire resistance, while house doors focus more on weather protection, burglary resistance and options like fanlights/glazing. Our range includes models for both uses with different fittings.
Can an external door be installed DIY and what are the minimum requirements for the opening and tools?
DIY installation is possible with experience: the opening must match the door size (e.g. 9x21 or 10x21); you need a spirit level, anchors, expanding foam and seals. Leave 10–20 mm installation clearance around the frame and check plumb and level before fixing.
How to improve thermal and sound insulation of an external door during installation?
Choose doors with internal insulation, multi-seal gaskets and a tight door frame; use quality expanding foam, a thermally broken threshold and additional seals during installation. Accurate sizing (9x21/10x21) and sealing of joints greatly reduce heat loss and noise.
