It’s a customer favourite because once it’s installed it requires minimal upkeep and continues to look fantastic.

Silicone Silicate Render is the most popular hybrid silicone render, offering great performance and great value. Silicone Silicate is fantastically versatile, providing the key benefits of a thin coat render with the added boost of self-cleaning and breathability that the silicone technology provides. Silicone Silicate is perfect for a standard classic finish that will maintain its brilliance in the long term.

Acrylic Render is the best value render. It is impact resistant and is most well known when it comes to coloured render as it retains the colour pigment even after extended exposure to UV. Acrylic Render achieves a vibrant, stand out finish.

WHAT’S THE MAIN REASON YOU FEEL COLD AT HOME? | 4 KEY FACTORS ✔️

If your home feels colder than it should, you’re definitely not alone.
Every winter, thousands of homeowners wonder why their heating doesn’t seem to keep the chill away.
In most cases, the problem comes down to a few key issues.
Here are 4 main reasons why your house might feel cold — and what you can do about them.

​

​

1️⃣ Poor Insulation

Insufficient or old insulation is the most common cause of a cold home.
Walls, roofs, and floors without proper insulation let warm air escape and cold air enter.
Upgrading your insulation can make a huge difference in comfort and reduce your heating bills.

​

​

2️⃣ Air Leaks and Drafts

Even small gaps around windows, doors, or pipes can cause noticeable heat loss.
Cold air sneaks in through these openings, making rooms feel drafty.
Sealing gaps with weatherstripping or foam sealant is a simple and effective fix.

​

​

3️⃣ Inefficient Windows

Single-pane or poorly sealed windows allow heat to escape quickly.
Replacing them with double-glazed or energy-efficient windows can help keep warmth inside.
You can also use thermal curtains for extra insulation.

​

 

4️⃣ Heating System Problems

Sometimes the issue isn’t with your home’s structure but with the heating system itself.
An old or poorly maintained boiler, furnace, or heat pump may not distribute warmth evenly.
Regular maintenance and system upgrades ensure better performance and lower energy costs.

WHY IS IT COLDER INSIDE MY HOUSE THAN IT IS OUTSIDE?​

A house is made up of different building materials connected together to form a thermal barrier — one that can be measured by something called a U-value. The lower the U-value, the better your home is at keeping the heat inside.
So why does your home sometimes feel colder than the outside air? In most cases, the walls — and the materials they’re made from — are the main reason.
Some construction materials are naturally “cold” in structure. You are free to copy and share the text from this blog, as long as you provide proper credit and a link to the original source - https://insulationgo.co.uk/.
They take a long time to heat up, and they can draw warmth from the indoor air until they reach a certain temperature. The good news is that once these materials absorb enough heat, they can hold on to it for a long time.
But there’s a catch: this only works if the walls are properly insulated. With the right insulation, the structure of your home can hold either warm or cool temperatures for long periods. As a result, even rapid changes in outdoor temperature won’t affect the inside of your house right away.
That’s why, in summer, you might walk out the door and feel a wave of hot air — then come back inside and feel like you’ve stepped into a fridge. That cooling effect is a sign that your home is well insulated and effectively resisting overheating.
This effect is most noticeable on sunny days with passing clouds. Outdoor temperatures can rise and fall quickly, while your home’s indoor temperature remains much more stable.
