Outstanding heat insulation no longer requires fitting the profiles with inserts by hand. The profiles are supplied pre-filled with foam.
The foam is injected into the profile chamber in the extrusion plant. The window manufacturer then receives the finished foam-filled profile off the shelf.
The foam is kept in place inside the profile by pressure and not surface bonding. When the window sections are cut into pieces, the foam falls out of the profile and can be recycled separately.
Sash profiles with IKD® technology can achieve Uf values of < 0.89 W/(m²K) when used in combination with STV® static dry glazing.
When used together with STV® technology, standard element sizes do not need steel stiffening elements. This saves weight, reduces transportation costs and makes installation easier.
The profiles can be cut, heat sealed and finished as normal.
The IKD® profile supplied in combination with STV® technology makes it more difficult to pry or force open the window, due to the hardened foam core and the full adhesive bonding between the pane and frame upstand.
GEALAN is a pioneer in factory foam filling of profiles and launched the first foam-filled window and accessory profiles back in 2010.
Today GEALAN has a wealth of expertise in how to incorporate this technology into profile production.
