About Loft Insulation

About Loft

Loft Insulation is an unbonded, Glasswool insulation designed with optimal thermal properties and excellent coverage and blowing characteristics. Loft can be installed into both new build and existing ceilings.

It can be used to form the total thermal solution or as an additional thermal layer to existing insulation. Loft should only be installed by Approved Installers to ensure the highest quality and installed performance.

Loft Insulation can be used for both retrofit and new build applications. The product is specifically designed to fill all gaps and voids, creating a complete thermal barrier against heat loss or gain. The product can be installed in open roofs, skillion roofs or tight roof cavities with access issues.

The product also has excellent acoustic performance and is made with up to 80% recycled post-consumer glass.

Loft Insulation is capable of achieving very high installed R-Values. This makes it the perfect insulation product for ensuring compliance with the new H1 insulation standards. Click here to view further technical information on Loft.


High Thermal Performance

Blown insulation makes it simple to achieve high thermal performance.

Noise Transfer

Loft Insulation helps absorb sound waves and reduces noise transfer in the home.


Loft is fast and easy to install by accreditated installers and available nationwide.

Good for the

Loft is manufactured from up to to 80 percent recycled glass content.


Is Loft Insulation completely safe for the family?

Loft is made up to 80% recycled glass and inert materials that are non-combustible and can help inhibit the spread of fire. For recessed lights we specify XLP protectors around every light. Loft is a non combustible material.

Loft mineral wool insulation will not exceed the Gib 2010 Guide maximum weight until R10, so is suitable for most gib board or plaster ceilings. The most critical factor for safe, long-term performance is a correct installation system. Loft is a proven performer since 1995.

Loft Insulation is extremely durable and has a life expectancy of over 50 years!

Why is roof insulation so important?

I bet you didn’t know that over 30% of your homes heating cost could be attributed to the fact your room may not be insulated? The same can be said about over 30% of your comes cooling costs!

Well once you know its quite obvious. Warm air, without something blocking it and left to its own devices, will tend to raise upwards. Whereas colder air will tend to drop. Pretty obvious so far.

Now think how this simple physics interacts with a roof or ceiling without insulation. If your heating a room, that heated air will tend to ‘sit’ against the ceiling – warming the ceiling. So if it is not insulted that warmth gets transferred into the roof space and outside your house! Also the loss of the heat results in the cooler air ‘dropping’ in the room, so you end up with a thermal cycling of the warm air to the ceiling until all the available warmth is lost. This is very expensive.

A similar thing happens when you try to cool a room but in reverse. During a hot day the roof space gets very hot, and given its a roof with no real holes in it you get a ‘stack’ of hot air sitting in your roof space heating up everything it touches; including the ceiling. So then the ceiling starts to get warm and in turn heats the air against it. Now where are most fixed aircons in homes?. Yes, right up high on the wall, so they are then trying to cool down already warmer than normal air. Its actually worse than this, as the temperature gauge in the aircon unit is constantly measuring the temperature at its on the wall location and not that at floor level, so it will try to ‘over cool’ when it does not need to.

Put both of these together and you will find 40% of both your heating and cooling costs are going out of the roof!

Why choose Loft blown roof insulation?

Quite simply Loft ceiling insulation works to keep the outside temperature out and the inside temperature in! Think of it like a lid on a chilly bin or vacuum flask, if you put hot food in it stays warm and if you put cold food in it stays cold. It works to stop/slow temperature transfer. The better the insulation grade or type of insulation product you use the less temperature transfer there is, so the better the insulation works. Inadequate ceiling insulation and air leakage are leading causes of energy waste in most homes.

Correctly designed & fitted insulation:

  1. Saves money and our nation’s limited energy resources
  2. Makes your house more comfortable by helping to maintain a uniform temperature throughout the house
  3. Ceilings warmer in the winter and cooler in the summer.

Poorly insulated homes are usually cold & damp, with occupants crowded over a heater in one area to keep warm. Homes insulated with the full proven systems like Loft use similar amounts of energy to keep your whole home at a healthy, comfortable temperature.

How good is Loft Insulation?

Loft is a premium insulation produt, and one of the best insulation products available allowing you to keep the outside temperature our and the inside temperature in!

The total installed thermal roofing insulation effectiveness of Loft is superior to batting or blanket, as it covers the full ceiling – without joints, gaps, thermal bridging, or vented cavities commonly found between linings and batting or blanket insulation. It provides premier insulation values. Batting insulation or blanket materials need at least two layers to achieve the same installed thermal effectiveness of Loft insulation.

Old insulation removal may be necessary before new Loft insulation is installed eg insulfluf removal. Talk to us today about installing Loft insulation into your roof or attic.
