In 100 years of their production we already know something about that. How do you recognize quality doorframes?
The latch bolt goes in the opposite sheet metal - the resistance of the door depends on its resistance. We always do anchoring in the door jamb - it is the strongest solution (compared to anchoring in the doorframe lining).
No simulations - we test real doors. In our own laboratory and in the state laboratory - as the only manufacturer on the market.
As the only manufacturer we can produce the doorframes of almost all 200 materials which we use for door manufacturing. And all these in 7 models.
Every handyman can manage our doorframes and doors. But the best thing is professional installation - this is how you can get a 5-year guarantee (the longest one on the market).
It depends on whether there are metallic doorframes in the interior or at the apartment entrance. Sapeli is number one on the market with regard to lining of metallic interior doorframes without construction works. If you wish to have the safety entrance door in your apartment, we mostly recommend removing old doorframes and fitting the building opening with new safety doorframes.
In such case it is worthwhile to replace the door and reduce heating costs of your household.
For treating SAPELI door and doorframes surfaces use regularly available gentle detergents which are designated for these surfaces (veneer=wood, HPL, CPL, Sapdecor = laminate, etc.). In SAPELI, you can buy special detergents which do not harm your SAPELI doors and doorframes when treating them.
