Responding to Garden Room Insulation health and safety.

Following the events at Grenfell Tower, our thoughts are with everyone affected by this devastating tragedy. We, like many construction professionals, continue to closely monitor the response and feedback following the safety testing on similar insulation products.

We would like to reassure our existing customers and potential clients that we are confident that the Polyisocyanurate that we use throughout our garden office installations (the most popular insulation in the home building and renovation sector) is safe when used within our building fabrication process. This is due to a combination of several factors;

At Smart we do not use the aluminium bonded insulation (Polyethelene) or any rain-proof cladding that is forming part on the ongoing investigation. The 40mm of Polyisocyanurate used in the walls, the floor and the ceiling of every Smart are encased within the wooden wall cavities. The unique nature of our TuSC construction of our chassis ensures that the base of the garden office is sealed and prevents the ‘chimney effect’ of the intake of oxygen through the wall cavity, causing fire to spread upwards, as appears to have been the case in this devastating incident.

All Smart Garden Office buildings are single storeys, usually under 2.5m tall, and experts are currently indicating that this chimney effect seen at Grenfell is thought to have been compounded by the height of the building, drawing the flames up through the cavity.

We will continue to follow the ongoing investigation and the advice of BRE, we are confident that our fabrication methods and use of Polyisocyanurate do not pose an increased risk to our garden office customers.

If you should have any concerns please do not hesitate to contact us.
