Windows and doors must be constructively protected with a wood preservative in accordance with
the Danish window industry’s technical provisions (Vinduesindustriens Tekniske Bestemmelser), and
there must be no bare wood in the glass rebate. Air and water tightness must be documented in a
test report issued by an authorised institute.
The products must be classified as “excellent” according to the performance description 2,
“Windows” of SBI (The Danish Building Research Institute) . Windows and doors must be DVClabelled and supplied with a 10-year warranty.
Wood

begins.
Aluminium
The aluminium profiles must be manufactured from alloy ALMgS of 0.5 according to DIN 17615.
There must be no double frames or mullions anywhere in the windows and doors.
Frames
Design
Wooden frames must be fitted with an aluminium section that separates the wood and the aluminium
in a dry and a moist zone, respectively. The aluminium section must be made with drain holes that
can drain off any ingressing moisture without it coming into
contact with the wooden section. The wood dimension must be 68 x 42 mm and 16 x 68 mm for
inward-opening designs.
Sashes
Design
Wood sashes should have a clipped-on external aluminium weather shield to secure the glass.
Aluminium sashes must have a clipped-on internal wood moulding to secure the glass.
Window sashes:
56x63mm for outward opening (Standard)
56x56mm for outward opening (solid hardwood)
60x66mm for inward opening
Door sashes:
54x58mm / 54x60mm / 95x61mm / 105x56mm for outward opening.
66x60mm / 72x61mm / 97x61mm / 105x60mm for inward opening.

SURFACE TREATMENT
Wood
Only water-based wood preservatives may be used for priming. The wood must be surface-treated
with a water-based, diffusion-open acrylic/alkyd paint approved according to NORDTEST BUILD, NT
229. Both the primer and the paint used for surface treatment must contain fungicides. Coat
thickness front: 60-80 my dry. Coat thickness back: 30-40 my dry. Sand the wood lightly before
applying the last coat. Frame and sash components must be primed and surface-treated prior to
assembly to ensure optimum protection of end grain and dovetails.
Aluminium
The aluminium frame section must be polyester powder-coated following prior chromating, coat
thickness 60-120 my, or anodised with a coat thickness of 20 my. All frame joints must be sealed to
prevent moisture from ingressing into the sash.

Fittings
All fittings must be made of naturally anodised aluminium or zinc electro-plated and
yellow-chromated steel or plastic.

WINDOW TYPES
Fixed light
Fixed frames must be clearly distinguishable from moveable parts in respect of design
and dimensions to ensure that the function of the window is easily identifiable.
Side/bottom-hung windows
The sash must be fitted with single-handle operated fittings with concealed jacks. When turning the
handle, it must be possible to choose between a side-hung or bottom-hung function. The side-hung
function must allow the sash to open inward up to 90 degrees. The bottom-hung function must allow
the sash to be retained in an open position and produce a ventilation gap of approx. 10 cm at the
top.
Side-hung window
The sash must be fitted with casement catches and window stays. The sash must open up to 90
degrees. Any opening restrictor must have adjustable friction.
Side-/bottom-hung balcony door
The sash must be fitted with single-handle operated fittings. When turning the handle, it must be
possible to choose between a side-hung or bottom-hung function. The sidehung function must allow
the sash to open inward up to 90 degrees. The bottom-hung function must allow the sash to be
retained in an open position and produce a ventilation gap of approx. 10 cm at the top.
Side-guided window
The sash must open outward up to 90 degrees and be retainable in any ventilation position using a
friction bolt. When fully opened, the external surface must be cleanable from the inside.
Top-hung window
The sash must open outward and be retainable with a casement stay for ventilation.
Top-guided window
The sash must open outward and must produce a ventilation gap in fully open position. The balance
arm must have built-in friction, allowing the window to be retained in any open position.
Top-swing window
The sash must open outward and allow 180-degree tilting where it is retained to allow cleaning from
the inside. The window must be fitted with a child-proof lock which limits window opening to approx.
10 cm. It must be possible to retain the sash in a ventilation position.
Patio door
The door must open outward and be fitted with an internal lockable handle which activates three
closing points. The sash must be fitted with an adjustable friction brake which limits door opening to
90 degrees. The sash must be hung on 3-4 hinges.
Light entrance door
The door must be outward-opening. When locking, the closing handle must activate three closing
points. The sash must be hung on 3-4 hinges. The door must have a built-in lock case for a dropshaped cylinder. The sill must be fitted with a protective aluminium strip or a handicap-friendly
