Do solid panel doors achieve better U-values than glazed entrance doors?

Marginally. Norrsken’s Passive House range of solid panel doors typically achieve whole-door Ud values around 0.74 W/m²K, while glazed entrance doors achieve around 0.76 W/m²K. Glazed, partially glazed (stable doors, for example) and solid entrance doors in the range can all be specified for Passive House and high performance builds.

What U-value does an insulated panel door achieve?

A well-specified insulated panel door with a thermally efficient frame can achieve Ud values below 0.80 W/m²K, meeting the Passive House Institute's threshold for external doors. Norrsken's Passive House panel door configurations achieve Ud values from 0.74 W/m²K. The frame material and insulated core specification are the primary determinants of whole-door performance.

Are panel doors suitable for contemporary architecture?

Panel doors are particularly well-suited to contemporary design, offering clean, uninterrupted façade profiles with complete freedom over groove patterns, hardware placement, and inset glazing sections. Powder-coated aluminium cladding in any RAL colour, combined with flush or shadow-gap detailing, delivers a precise, architectural aesthetic well-suited to modern residential and commercial projects.

Can panel doors include glazing?

Yes. Partial glazing - inset panels, sidelights, or narrow-light configurations - is available within the panel door range. Glazed sections use triple-glazed units to maintain consistent whole-door performance. The ratio of glazed to solid area affects the overall Ud value, which our technical team can calculate during the specification process.

What frame materials are available for panel doors?

Norrsken's panel doors are available in alu-clad timber and all-timber frames. Alu-clad provides a low-maintenance exterior in any RAL colour while retaining a timber interior. All-timber configurations are available where a fully natural internal aesthetic is preferred or required by planning conditions.

How are panel doors secured?

Norrsken's panel doors use multi-point locking systems as standard and are manufactured to PAS 24:2016 enhanced security requirements. The laminated timber core provides inherent structural strength, and all hardware is specified to complement both the aesthetic and the security performance requirement.
