All about loft insulation

A quarter of heat is lost through the roof in an uninsulated home. Insulating your loft, attic or flat roof is an effective way to reduce heat loss and reduce your heating bills. Installed correctly, loft insulation should pay for itself many times over in its 40-year lifetime.

And having good loft insulation also helps you reduce your home’s carbon footprint. The better insulated your home is, the more efficient your heating system will be – reducing emissions as well as saving you money on bills.

What do we provide?

Qualifications

Our Loft Installation Teams are trained and equipped to undertake all essential pre-installation checks to ensure compliance with the PAS 2035.

As a KIWA Approved Installer, one of our Technical Leads will undertake a pre-installation site assessment, where they will work in collaboration with you to identify the correct insulation solution for their property.

We are familiar with calculating the type of insulation required to achieve maximum thermal transmittance (U value) including, for loft top-ups, how best to treat existing insulation (remove or supplement).

Experience

We also ensure that our operatives fully understand how best to install the insulation material in relation to the specific type of roof/loft.

If required, our operatives will remove items stored in the loft, taking care not to cause damage and with consideration as to how these can be put back upon completion.

We always advise the Applicant if it seems likely that any of these items will not be able to be returned to the loft for future storage.

Ventilation

A well-ventilated loft is essential for maintaining the overall health and longevity of your property. While it may seem like an inconspicuous part of your house, neglecting proper loft ventilation can create a number of problems, including condensation.

That’s why we pay particular and specific attention to the ventilation of the loft space, making sure that no existing ventilators are blocked and installing additional means of ventilation if required.

By reducing the possibility of condensation developing in your loft, we can help to reduce the risk of damage to anything you’ve have stored there.

In addition, it is essential to prevent your loft insulation getting damp as this will make it less effective and drying out insulation materials can be difficult.

Installation quality

Our installers will use their expertise and experience to ensure that your insulation is installed safely and in compliance with the relevant standards and regulations.

This will include making sure that electrical cables are laid over the insulation or placed in a channel, that light fittings not marked with an “F” are covered with a fire barrier, that pipework and stop taps are lagged with a BBA approved material. They will also check that water tanks are correctly fitted with insulating jackets and accessible via suitable walkways.

We always make sure that the loft hatch is properly draught-proofed and that the loft ladder is functioning correctly. Finally, any unavoidable damage to surrounding areas and decorative finishes are then made good.
