How To Insulate Your Loft

How To Insulate Your Loft

Proper insulation in loft spaces can significantly contribute to maintaining a consistent temperature in your home and reducing your energy bills. Here's a step-by-step guide on how to insulate a loft ladder hatch you already have in your home.


First, evaluate the current state - Before starting any insulation project, carefully inspect the existing condition of your loft ladder or hatch. Look for gaps, cracks, or any areas where air might be escaping. This initial assessment will help you determine the type and amount of insulation needed.


Secondly, choose the right insulation material - selecting the appropriate insulation material is crucial. Common options include fibreglass, foam boards, or spray foam insulation. Ensure the chosen material provides a good balance of thermal resistance and is easy to work with in the confined space of the loft.


Now measure and cut the insulation - measure the dimensions of the loft ladder or hatch and cut the insulation accordingly. It's important to create a snug fit to prevent any gaps that might compromise the insulation's effectiveness. Use a utility knife or appropriate cutting tool for precision.


Installing a weather strip - apply weather stripping around the edges of the loft hatch or ladder to create a tight seal when closed. This additional barrier prevents drafts and heat loss, creating a more energy-efficient home.


Make sure to seal gaps and cracks - seal any gaps or cracks with expanding foam or caulk. Pay close attention to joints, corners, and any areas where the ladder or hatch connects to the ceiling. This extra step ensures a thorough insulation job.;


Consider an insulated loft door - if your loft space is regularly used or serves as a living area, you might want to invest in an insulated loft door. These doors come with built-in insulation and provide an additional layer of protection against heat loss. All FAKRO loft ladders come with an insulated door as standard.


Our most insulated loft ladders are:


The LWT and the LWT Passive House. The LWT Passive House specifically is a technically complex design developed for the demands of a highly energy-efficient or a PassivHaus homes. This comes with a Passive House insulation kit to ensure the perfect seal is created between the ladder and ceiling without thermal bridges. It has a U value of 0.51W/m(2)K and comes with polystyrene insulation, a triple system of seals and a PassiveHaus certificate.

Next is the LTK Energy with a U value of 0.68W/m(2)K. This comes with a double system of seals to improve the air tightness, a 6.6cm thick hatch and is made for homes that have a significant temperature difference between the loft space and the top floor.


We also have an LWL Extra which has extra safety with an added handrail and extra insulation with a U value of 0.74W/m(2)K and insulation thickness of 5cm.


The rest of our loft ladders come insulated with a U value of 1.1 or lower (for U values, the lower the number the better the insulation) as standard.


Finally test for effectiveness - after completing the insulation, perform a simple test by feeling around the edges of the hatch or ladder for any drafts. If you've done a thorough job, you should notice a significant reduction in airflow.


By taking the time to insulate your loft ladder hatch, you not only increase the comfort of your living space but also contribute to a more sustainable and energy-efficient home. It's a small investment that pays off in both the short and long term.


If you are looking for a loft ladder that is already insulated then at FAKRO we have 16 insulated ladders to choose from - from fire-resistant to passive house approved. Please contact to find out more or visit our website.
