Next, refit your door while ensuring that there is at least a gap of 2mm between the frame and the door before bolting the hinge back into the place. Finally, close the door's leaf as well as lock it in place.
In case you are using a panel that comes with a beaded frame, then apply a scrim tape before plastering. However, if you have chosen the option of picture frame then you won't require any plastering work. Remember, it takes around minutes to install the Loft Hatch and it essentially depends on your experience and capabilities. Also, the Loft Hatch's weight would depend on its size.
Usually, the larger its size, the heavier it is. Please note that if the Loft Hatch is fire rated then the door's insulation will be covered using metal backing which will again add to the Loft Hatch's weight, which should typically be in the range of kg. Your Cart. How to Install Loft Hatch? Look for the Right Size The first step to installing a Loft Hatch is to measure the size that you would need so that it can be manufactured as per your requirements.
Standard loft hatch sizes can only really be used with a traditional extension ladder, that is placed inside the framework of the loft hatch to allow you to climb in and out of the loft. How to Enlarge a Loft Hatch New opening marked on joist tops with 4 inches added either side to compensate for timbers. Screw down and fix in temporary supporting timbers. Cut away ceiling section and joists to create new opening.
Fix facing timbers into your new loft hatch opening and screw them in place. Then to make the actual hatch itself either cut 25mm MDF to size or cut a cheap, ply flush door down, fill the cut end with timber and then rest it on top of the lining.
Spiral staircases take up the least area but are typically more expensive. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Home Learn. How do you measure for a loft hatch? For cutting the ceiling, the opening size plus twice the thickness of the lining material that will be fitted.
The add twice or four times the thickness of the trimmer depending on whether or not you are doubling up the trimmer joists. Assuming you are 'retro-fitting' the loft trap and the finished ceiling is already in the way, I would cut and remove the section of ceiling first once I have marked out my aperture without cutting any joists.
This will let more light up into the roof space so I can work more easily. Use a jab-saw to start the hole off then finish with an old handsaw if you have one. Plasterboard will ruin the teeth on a good handsaw so don't use a new one.. Cutting and supporting joists or roof rafters is called 'trimming'.
You'll need to use timber that is the same size and strength as the joists you are trimming and for the lining material afterwards, 90mm x mm smooth planed timber is generally fine and inexpensive enough.
When bracing timbers like this above a pre-finished ceiling retro-fitting a loft trap , I tend to use screws rather than banging nails in that need to be removed later as this reduces the risk of cracking the ceiling or disrupting it too much. You'll most likely need to redecorate anyway, but the less patching up or repair work the better. If cutting one joist out, a single trimmer can be strong enough.
If cutting more than one joist then you need to double up the trimmer so it is strong enough to carry the weight of two or more. Keeping it a few inches back from the line to be cut, fix some scrap timber across the joists to hold and support the one that is going to be cut out and removed. Cut the joist out that is in the way using a hand or circular saw, and fix two pieces of timber across.
Nail them to the outer joists and to the trimmed joist to stop it dropping down now the middle section is cut out. If necessary, more trimmers in the opposite direction can be used to position or resize the loft trap. Unless you are installing a replacement loft trap or one in an existing property rather than a new build It's likely that a frame will be installed before the plasterboard and then after the flushing or plastering has been done the trap door, stops, catch and architraves will be fitted.
It's a bit like installing a normal door frame. You might find it easier to build the frame on the floor and then slide it up into the trimmed area, otherwise you can install 'in-situ'.
For strength the frame can be housed out like the picture below, this is more important if you are hinging a door not so much if the trap will simply sit down on top of the frame. It will need to be perfectly square so the door works and the architraves are easy to install which means cutting opposing sections to equal lengths.
