Addroom® Modular Garden Room W4m x D3m

Insulation is important in helping to maintain the temperature inside your garden room, so you can maximise its use all throughout the year. It will help to retain any generated heat inside to keep you warm during the colder months. It will also help to keep the building cool inside during hot summer days. This means you will have a comfortable living space no matter what time of year it is.  

All Addroom Garden Rooms come fully insulated with polyisocyanurate sandwich panels making up the walls and floor of the building. The roof also comes as an insulated sandwich panel with a high density polyurethane core. The walls have a 70mm cavity to increase airflow and ventilation, with two skins of 25mm thick insulation, while the floor is made with 25mm thick insulation. We use polyisocyanurate insulation as it gives high thermal efficiency, and is known to be far superior to alternative materials used by other companies, such as polystyrene, rockwool or bubble wrap.

Whatever you choose to use your garden room for, security is important to keep all your treasured belongings and valuable items safe. This is why we include PVCu French doors with an industry-leading 12-point locking system, as well as multi-point locking windows with key locking handles.

Our 12-point locking system consists of four shoot bolts, three espagnolettes, three hook bolts, a locking latch and a 6-pin euro cylinder. Our window locking system consists of mushroom-headed espagnolettes which move in opposite directions into metal keeps.

Our Addroom Garden Rooms come with an easy-to-install insulated roof panel that has an attractive grey slate tile effect appearance. This offers the best performance and aesthetic finish, imitating a traditional design that gives your building a modern look.

The 65mm thick insulated sandwich panel provides high levels of thermal efficiency and good sound insulation. It has a polyurethane insulation foam core protected by two sheets of pre-lacquered, galvanised and profiled steel. The upper tiled effect layer is formed by a total of six tiles, not five like others do, as it offers more resistance and insulation capacity. Polyurethane is a high density material with fantastic insulative properties. The lower steel plate is finished in basic white.

The overlapping joining system gives the roof tight connections that help prevent leaks and humidity, ensuring warmth is kept in and doesn’t escape through the ceiling. The high quality roofing system has been subjected to numerous tests and controls to ensure the effective performance of its qualities and characteristics.

The tall walkthrough height of 6'0" (1.84m) means you should be able to walk in and out of the doors of your garden room without running the risk of bumping your head.

When comparing the door heights with others be careful of companies that also include the door frame in their measurements to make is sound larger than it really is.

WPC (Wood Polymer Composite) is a fantastic material to use for outdoor buildings and applications. It has all the benefits of plastic and timber combined, meaning it is very low maintenance, resistant to water and highly durable. The external walls can either be left natural, or painted to your preference using a Multi Surface Paint. We have used 'BEDEC Multi Surface Paint' for over eight years, and find it has fantastic adhesion, wear and colour fastness.

Please note that unpainted/untreated areas of WPC may differ slightly in colour due to manufacturing processes.
