How to guide- How to insulate a loft

Published On: 09/03/2021Categories: How To Guides

Step 1- line your cold water tank with the jacket
Step 2- Insulate the pipes, use a snap off knife to cut the insulation and secure it with duct tape. Insulation shouldn’t be laid over electric cables so where possible clip them to the roof joists or gently lift them
Step 3- If you have recessed lights, install down light protectors
Step 4- once the insulations roll is in position, measure the width of roll you need to fit between the joists and cut appropriately.
Step 5- position the crawling boards in the furthest corner of the loft. Start with a minimum gap of 25mm between the eaves and the insulation and beginning laying. Maintain the gap along opposite sides
Step 6- Make sure the wall plate is covered, then roll the insulation out. Move backwards so you are working towards the centre of the loft to avoid putting any weight directly onto the insulation. Push the insulation so it fits snug between the joists, but do not compress it.
Step 7- When you reach a cross beam use a straight edge and a knife to cut the insulation to size. To join two lengths simply push them together. Continue until the first layer is complete.
Step 8- The recommended loft insulation depth is usually between 270-300mm, in order to reach this, repeat this process but lay it at 90-degrees to the first layer and ceiling joists.
Step 9- Continue until the entire loft is covered.
Step 10- Measure the loft hatch and cut the insulation to size, you will probably need two layers. Wrap the cut insulation in some of the packaging and attack it to the loft hatch using a staple gun or large headed tacks.
