DOMUS Window Construction

Frame and sash
The DOMUS frame and sash is formed using joined laminated sections, this gives improved dimensional stability and enhanced weather resistance. A 54mm deep frame adds to the strength and durability of the window.

Glass rebate
The glazing rebate is 18mm deep. This helps to protect the edge seal of the double glazed units.

On Secured By Design units the glass is bonded at all four corners with an adhesive that requires a force of at least 60kgf to break making it difficult for intruders to gain access.

Ventilation
Rationel’s unique and patented user friendly push vent fitted into the side jamb offers controllable trickle ventilation. It is easy to operate and does not disturb the overall harmony of the window. The vent is invisible from the outside and internally the vent is a flush fitting aluminium plate in the side frame.

Glass
All windows are delivered with 26mm double glazed units. As standard, we offer low energy units that give a centre pane U – value of 1.2 W/m2K.

The low U – value means lower heating bills since thermal loss is reduced and the extent of cold waves of air passing through the window is also reduced.

Weather – strips
DOMUS windows are fitted with grey EPDM thermoplastic PVC free weather strips fitted in one continuous piece that does not degrade with cleaning.

Glazing beads
Glazing beads are fixed with hidden nailing to create an unbroken surface and ensure an elegant and durable finish that prolongs the lifetime of the glazing.

The most exposed and weathered glazing bead is the bottom glazing bead which is made from aluminium and can be painted to match the window.

Ironmongery
The ironmongery is adjustable. This allows precise adjustment of the windows within the frame to ensure optimum operation.

Ironmongery is concealed to allow a more uniform appearance and a longer lifespan.
