Celebrating Adrian Blyth’s Retirement After 23 Years at SPC
Last week, we bid farewell to Adrian Blyth, our long-serving Financial Director, who has retired after an incredible 23 years with SPC.
Adrian first joined the business in October 2002 as a Management Accountant. Over the years, he became an integral part of the finance team and a respected leader within the company. Known for his financial insight, sense of humour, and sincere care for his colleagues, Adrian brought both professionalism and personality to everything he did.
When asked what he enjoyed most about his time here, Adrian often said it was the people, echoed by many of his colleagues who’ve worked closely with him over the years.
Outside of work, Adrian is just as accomplished. He once ran the London Marathon in an impressive 2 hours and 54 minutes and was a proud member of the Leicester Road Hogs running club in the 1990s. In more recent years, he’s taken on a new role: passionate supporter (and investor!) in his grandson’s golfing ambitions.
At his farewell presentation, our Sales Director, Jeremy, shared a few fun retirement sayings that brought plenty of laughs:
- “You’re retired, not expired”
- “Say hi to the pension, bye to the tension”
- “Behind every retired man is a wife who wishes he’d go back to work!”
Adrian, on behalf of everyone at SPC – thank you for your dedication, commitment, and everything you’ve done for the company. We wish you a very happy and well-deserved retirement. You’ve certainly earned your licence to chill!
Beat the Heat with Radiant Cooling – iTwenty Eight Industrial Radiant Panels from SPC
Our iTwenty Eight Industrial Radiant Panels provide an energy-efficient alternative, offering radiant cooling when paired with a suitable system like a reverse-cycle heat pump. Whether you’re working in a warehouse, factory, or distribution centre, these panels help create a more comfortable environment, without noisy fans or draughts.
Why Choose Radiant Cooling?
Radiant cooling works by absorbing heat from the space through cooler surface temperatures, so people and objects feel cooler, even if the air itself isn’t being actively chilled. It’s ideal for high-ceilinged, open spaces where traditional air conditioning isn’t always practical or efficient.
Why Choose iTwenty Eight Radiant Panels?
Our iTwenty Eight Radiant Panels are specifically designed with industrial spaces in mind. Here’s why they are the ideal choice for your cooling needs:
- High Performance: Deliver superior cooling performance, making them perfect for large industrial areas.
- Durable: Engineered to withstand harsh industrial environments, ensuring long-lasting performance.
- Easy Installation: Designed for straightforward installation, reducing downtime and labour costs.
Key Features:
- Dual purpose panels – radiant heating and cooling
- Quiet & efficient – no forced air movement
- Modular sizes – panels up to 6m wide, runs up to 70m
- Lightweight & durable – aluminium fascia, large steel waterways
- Perfect for: warehouses, production lines, storage units, and large open-plan industrial settings
Quick Tips: Staying Cool in Industrial Workspaces
Even with radiant systems, keeping a warehouse or factory cool in the summer takes more than one solution. Here are a few extra ideas:
- Improve ventilation – Use high-volume, low-speed (HVLS) fans to keep air circulating
- Limit heat sources – Turn off unused machinery and lights
- Add shade – Use blinds or reflective films on roof lights and windows
- Hydration stations – Make sure cold water is available throughout the day
- Schedule smart – Move heat-intensive tasks to cooler hours when possible

Prevent Hot Air from Entering Your Warehouse with iForce Industrial Air Curtains
In busy environments like warehouses, distribution centres, and logistics hubs, keeping indoor spaces at a stable, comfortable temperature can be challenging, especially in summer. Constant foot traffic, forklifts, and delivery vehicles mean doors are often open for long periods, allowing hot air to flood in and place added strain on your cooling systems.

That’s where iForce Industrial Air Curtains come in. Specifically designed for large openings in industrial environments, they create a powerful, invisible barrier of air across open doorways. This barrier prevents the outside hot air from entering while keeping the cooler indoor air inside, helping you maintain temperature control, reduce energy costs, and create a more comfortable working environment.
Why Choose iForce Industrial Air Curtains?
Prevents Hot Air Ingress
During warmer months, iForce air curtains form a protective air barrier to stop external hot air from flowing into your workspace, making it easier to maintain a cooler internal environment.
Reduces Energy Costs
By preventing hot air from entering, your HVAC system doesn’t have to work as hard to maintain internal temperatures, helping lower your energy bills.
Supports Temperature-Sensitive Operations
For warehouses storing sensitive products such as food, pharmaceuticals, or temperature-controlled goods, maintaining a stable environment is critical.
Improves Working Conditions
No more uncomfortable hot spots near open doorways, iForce helps protect your team from external temperature fluctuations.
Minimises Dust and Contaminants
As well as blocking hot air, the curtain of air helps to prevent dust, insects, and pollutants from entering through open doors.
Robust Industrial Design
Built for demanding environments, iForce Industrial Air Curtains are engineered to perform in high-traffic, large-doorway settings.
Commercial Applications? Meet Our Forcefield Air Curtains
While iForce is ideal for industrial spaces, our Forcefield Air Curtains are designed for commercial environments such as shopping centres, office buildings, schools, and hospitals. They offer the same energy-saving and comfort benefits, perfect for main entrances and public areas where controlling the indoor environment is just as important.

Developing Our Team to Deliver Engaging CPDs
SPC’s CPD Academy
Earlier this month, members of our sales team took part in a tailored workshop designed to enhance their presentation skills. Joe, Omari, and Lewis were the first to take part, working through interactive training sessions that focused on delivery style, structure, audience engagement, and technical clarity.
This training (internally known as SPC’s CPD Academy!) is part of our wider commitment to professional development and knowledge sharing across the industry. By developing our people, we’re helping to raise standards not only within SPC but across the wider building services sector.
Why It Matters
CPDs (Continuing Professional Development) are a valuable tool for architects, consultants, and contractors looking to stay informed, meet compliance, and make confident design decisions. But to be truly useful, a CPD needs to be more than just a technical overview – it needs to be engaging, accessible, and relevant.
By focusing on presentation skills and delivery techniques, we’re making sure that every CPD session we offer gives attendees clear takeaways, practical insights, and an opportunity to ask the right questions in a supportive environment.
