Sisalation & Reflective Insulation

While bulk insulation works by slowing the heat transfer through the insulating material, foil insulation like Sisalation use their reflective surface to stop radiant heat. Contrary to what you might expect, insulation foil doesn’t need to face its reflective foil surface outwards ‘towards the sun’ in order to work, and in fact (for safety/anti-glare reasons), it is much more commonly installed with the reflective surface facing into the house. When used in combination with bulk thermal insulation such as Earthwool Wall Insulation, Sisalation foil insulation is very effective both in increasing the thermal efficiency of the building, as a windbreak, and also can serve as a reassuring guarantee that the thermal wall batts won’t come into contact with the brickwork. Without an air-gap of about 2cm, foil insulation won’t work as it should, and with no air-gap, the product is basically ineffective as an insulator.

Save Energy – Cooler in Winter and Warmer in Summer?

Sisalation, and other types of insulation are extremely effective in reducing the transfer of heat. This helps keep you warmer in winter and cooler in summer. If you’re fortunate enough to live in a properly insulated home, then you should already be benefiting from a significant reduction in your power bills. One of the simplest ways to save further even more energy, is by adjusting the settings on your home air-conditioner. Put simply: the greater the difference between the outside temperature and the temperature you set on your air-conditioner – the harder the air-conditioning unit will need to work to maintain your set temperature. While 22 degrees might seem like a perfect, year round temperature, being a bit flexible can save you money. Try setting it to 25 degrees in summer and 20 degrees in winter.

Another way to save energy is to plant shade trees on the sides of the house which are most exposed to the hot afternoon sun. This will reduce the temperature on the bricks or other external cladding which will in turn reduce the work load of the air-conditioner.
