Maria McGrane2024-05-29OS Holding recently completed a renovation of my kitchen/dining area and I couldn't be happier with their work. The job involved knocking down a load-bearing wall, installing steel supports, taking up the old floor and laying a new one as well as skirting boards. They also did the plumbing and electrical works, connected new radiators and did the painting to finish. The guys are very skilled in all aspects of their work and they are careful to fulfil all requests. They are also very tidy. I'm especially happy with the meticulous way the herringbone floor was laid. Vadim is easy to work with as he listens to what you say a a client and is always prompt to respond to calls and emails. I would have no hesitation in recommending OS Holding and I intend to contract them again when I get round to doing my attic!

The installation of tiles on both floors and stairs was completed to the highest standard. Additionally, the team maintained excellent communication throughout the project, keeping us informed of progress and any necessary adjustments. Their punctuality and respect for deadlines ensured the project was completed on time, which was crucial for our schedule. I highly recommend OS Holding for any construction or renovation needs.

Walls Pumped with Insulation
Cavity wall insulation is a highly effective solution for reducing energy consumption and enhancing the comfort of your home. By filling the gap between your external and internal walls, cavity wall insulation prevents heat loss, making your home warmer in winter and cooler in summer.

Lower Energy Bills: As your home retains heat more efficiently, your heating system doesn’t need to work as hard, leading to lower energy costs.
Improved Comfort: Insulating your walls eliminates drafts and cold spots, creating a more comfortable indoor environment.
Enhanced Energy Efficiency: By making your home more energy-efficient, cavity wall insulation reduces your carbon footprint and helps you contribute to environmental sustainability.

How Cavity Wall Pumped Insulation Works
Cavity wall insulation involves the injection of insulating materials into the space between your external and internal walls. The most common materials used are foam or bonded beads, both of which offer excellent insulation properties.
- Bonded Bead Insulation: Small beads of polystyrene are injected into the cavity and expand to fill the space. This method is highly effective for properties built after the 1980s and offers long-lasting, moisture-resistant insulation.
- Pumped Foam Insulation: Expanding foam is injected into the cavity to create a continuous barrier that prevents heat loss. This method is ideal for homes with larger cavities or those built before the 1980s.
Both options create an airtight barrier that helps keep your home warm in the winter and cool in the summer. The process is quick and minimally invasive, ensuring that you can enjoy the benefits of insulation without significant disruption.
