Insulation & Screeding For A Garden Room / Office

At Mitchell Plastering & Dry Lining Ltd, we specialise in professional floor screeding and insulation solutions for residential and commercial projects. A recent job in the West Midlands involved insulating and screeding a garden room/bar and office, producing a durable and energy-efficient flooring system.

Installing A Reliable Insulation System

To create a solid base for the screed, we started by installing 20mm polystyrene insulation and 75mm Celotex insulation over the client’s 1200-gauge polythene damp-proof membrane (DPM). This combination provides excellent thermal efficiency, helping to keep the space well-insulated throughout the year.

For additional protection and movement accommodation, we fitted a 25mm perimeter upstand along the edges of the flooring. A 6mm expansion strip was also added to allow for natural material expansion and contraction, preventing cracks and achieving long-term performance.

Floor Screeding With Gypsol Liquid Screed

Once the insulation was in place, we applied a tape-sealed polythene slip membrane to further protect the structure. The final step involved pouring 55mm of Gypsol liquid screed, creating a perfectly level and smooth finish. This type of screed is known for its fast-drying time and superior strength, making it an ideal choice for modern home extensions.

A Seamless, Energy-Efficient Finish

By combining high-quality insulation with precision screeding, we provided a long-lasting and energy-efficient flooring system for this home extension. The end result is a comfortable and durable foundation that supports the functionality of the garden room and office space.

At Mitchell Plastering & Dry Lining Ltd, we take pride in delivering expert screeding and insulation services, making sure every project meets the highest standards. This small but essential job in the West Midlands is a great example of how the right materials and techniques can enhance comfort and efficiency in home extensions.
