The ability of a structural framework to resist the racking forces caused by wind loading. Most of this strength is provided by the KRONOTEC OSB sheathing and its fixings.

Rafter
One of a set of parallel sloping beams that form the main structural element of a roof.

Reverse wall construction
In reverse wall construction the KONOPLY OSB structural sheathing is placed on the inside face of the studs, immediately behind the plasterboard lining, providing structural, fire protection and vapour barrier functions. ...

Ridge purlin
Ridge purlins are used on purlin roofs. They serve as the top rest for the rafters. As they have to bear half of the vertical load of the roof they are supported on props or walls at suitable points if …...

Rises
The vertical part of a step.

Rock wool
Fibrous insulation manufactured from molten rock or slag. Provides good thermal insulation and fire protection.

Roofs, cold
In cold roof construction the thermal insulation is placed between the rafters immediately above the upper storey ceiling, providing an unisulated roof space.

Roofs, flat
Roof construction where the roof deck is almost horizontal. The deck is made from a structural board such as KRONOPLY OSB covered with a waterproof membrane such as bituminous felt. Periodic maintenance …...

Roofs, panel
Roof panels can be used as an alternative to attic type roof trusses to provide unobstructed roof spaces for occupation. The panels are similar in construction to timber frame wall panels and enable a …...

Roofs, pitched
Pitched roofs of timber construction can be designed and constructed in a number of ways. Traditionally they were constructed on site with each piece cut and fitted to its neighbours. Following the second World War various forms of prefabricated truss were developed with the intermediate rafters and purlins cut and fitted on site. ...
