How to Get to Floor Beams in Attic Without Damaging Roof


Postby asheyash » Sun Apr 10, 2016 4:35 pm

May be a daft question but how do you get floor beams into the attic without taking the roof to bits my attic is 6m in length could i just use 2 lengths of 3.6m lengths and overlap or will i need a suporting wall/beam to do under the overlap. also if using a 400mm space between each beam what do i do when i come to the loft hatch?

thx

Increase the loft hatch to allow the beams to enter, I assume your going to install some sort of ladder or stairs.

you have to remove 2 rows of tiles front and back for a while to set the beams on the wallplates assuring they clear the existing by approx. 150mm for a sound floor I would use 195 x50mm
