uPVC profiles need to be reinforced with steel. uPVC profiles tend to be deformed under permanent loads. Since the interal steel profiles are interrupted at corners, a uPVC sash may lose its shape in some unfavourable conditions. The sash does not open and close properly in such cases. It is practically impossible to recover such deformed uPVC sashes. Similar weaknesses are valid for void panel doors as well.
Arbor products fill-in bigger openings in a much more robust way thanks to the naturally strong wood material processed with high technology. Our wood profiles, free of visible knots and other defects are made of laminated scantlings, preventing deformation through time. All cross-sections (according to DIN 34-1-1 D) are obtained with 0.2 mm tolerance and all profiles are connected with morise joints. Another distinction of our production is to use double tenons on mortise joints.
The profiles with less than 14 % moisture and 2 % difference in moisture are joined in both X and Z axis, thus neutralizing inherent stresses and preventing visibility of joints. Joints are achieved using D4, water and air impermeable glues.
There exists air and draining channels under our insulation glass units in our windows. Bead surfaces, free of screws and ribs are obtained after fixing glass units with special concealed nails. Unique solutions in product details and the finishing processes prevents risks of decay.
the cross-sections of Arbor profiles are designed to provide a longer use life, practicality and aesthetics. Our profiles have the below features:
- Water is drained directly and in a controlled way.
- Cavities and thin gaps that bear the risk of holding humidity and water are prevented.
- Glazing places are tp to relevant norms.
- Care is taken to keep all fittings in service in a long period of time.
- All edges and corners are designed to take over uniform and sufficiently thick layers of paint.
