Ceiling Insulation Installation

ceiling insulation installation

A well-insulated home gives increased comfort but decreased energy costs. A good ceiling insulation installation will keep you warm in winter and cool in summer. 

There are two main things to consider in gaining the best insulating results: selecting the right material and installer. Suitable bulk insulations include batts, polystyrene boards and loose-fill. 

In alpine climate, two layers are necessary to increase its thermal performance. One layer is between the joists and the other on top. There are hazards related to this such as safe places to walk on which may become unidentifiable when accessing the roof space. 

Once the insulation is removed for access purposes, it must be reinstalled in compliance with Australian standards. Those with concealed rafters are easier to insulate. But the ones with exposed rafter require products with higher R-value per unit thickness because of space limitations.

It’s also best to consult the manufacturer about installation clearances but as a general guide, here are the minimum clearance heights:

● R3.0 bulk batts - 130mm

● R3.0 polystyrene boards - 85mm

● For metal roofs, at least 25mm gap below the reflective surface is needed.

Ceiling Insulation Installers

Before insulating work begins, installers ensure that the power is turned off. They work away from any electrical wiring to avoid catching fire. The best time they install is in the morning and they always wear safety gears. 

Here are the major steps they follow on how to insulate a ceiling correctly.

Step 1. Properly measure up the ceiling area.

Step 2. Select the correct insulation type for the job and the correct R-rating, then calculate how many bales needed to sufficiently cover the entire area.

Step 3. Set up the ladder, get up and have a look around to see if anything needs tidying up. Check for damaged or exposed wires or nails, and pests such as wasps or bees.

Step 4. Once everything is ready, start the job by setting all the equipment up - work lights, tools, planks, couple of bales, while wearing the safety gears.

Step 5. Work first in the area which is furthest away from the access. Take measurements of the space between frames. Cut a 10 - 20mm oversize to fit snug friction using cutting board and straightedge. Do not leave too-big insulation between the framing as it reduces efficiency.

Purchasing the right product is critical but having it installed professionally and properly is also paramount. Through a wide list of trusted companies across Australia, finding the right ceiling insulation installers that you need is now very easy.
