“I’ve used low e for the past 15 months. I’ve found it to work fantastic is all conditions. I’ve probably got 20 vans with it fitted and I’ve had no complaints from any of my customers about being cold. Some of the vans are used for skiing holidays in places that are -20C and more.”

Alex E, Lancashire, UK

“Our customers are delighted with the rooms. We are now offering Low-E Insulation as an update in ALL our sheds, summer rooms and log cabins.”

Kate E, London, UK

“I found Pet Pad online and thought it was a fantastic idea. I’ve put them in all the kennels and pens my doggie hotel. A few of my customers saw them and asked about them so now I’ve started selling them too. Everyone loves them, especially the pooches!”

Helen B, Ireland

“We used Low-E Insulation to insulate outdoor water tanks. We used to lose a lot of water through evaporation in the summer months. It is made a huge difference. We have now insulated of hot water tanks indoors, and we have noticed our energy bills have gone down too. I’d definitely recommend Low-E Insulation.”

P Philip, Macclesfield, UK

“I bought the Low-E Insulation from eBay on a recommendation from a friend. It arrived very promptly and was very easy to cut and installing. I’m delighted! It’s certainly made a difference. I can feel that the kitchen gets warmer much quicker on the cold winter mornings.”

Andrea P, Dublin, Ireland

“The insulation came in a very easy to handle strip. It was easy to install and I haven’t had any problems since it was installed.”

Bill S, Porto Turistico, Italy

“The first time I used Low-E Insulation was on a project in Italy. We used it to simply line a closet on a yacht where there were issues with damp. I was amazed at how simple it was to install. I wish I found this material years ago. We’ve use it on a few projects […]

Stephen C, Cornwall, UK

“I bought a kit online to make window mats from Low-E Insulation. The insulation was very easy to cut to the exact size I needed. The kit came with suckers and everything else I needed. The mats are great. They are completely blackout and keep my van nice and warm even on very cold nights.”

Dave C, Dublin, Ireland

“The car was built in 1958 and I wanted to make sure it survived another 50 years once we had finished refurbishing it. The Low-E was easy to install and more importantly, it was very thin. You’d never know it was there and it seems to have made a big difference. We’re very happy with […]

“We used Low-E to line the interior and the engine bay of our NASCAR, its working really well”

Cameron J, UK

“We were unsure if Low-E Insulation would work for us so we ran a test. We insulated one van with Low-E and one with the traditional insulation we had been using. Then we brought both vans down to -4*C. The van insulated with Low-E held temperature 4 hours longer than the van without. The results […]

How to Make Insulated Window Mats

Low-E window mats are ideal for use in campervans and motorhomes but work just as well in cars and vans. Quick and easy to cut, they won’t absorb moisture and reflect 97% radiant heat. Warmer in winter and cooler in summer, your new window mats will block out unwanted light, reduce condensation risk and draughts allowing you to stay cosy and get a great nights’ sleep.
Simply follow the steps below to make your own bespoke Low-E Insulated Window Mats.

Please take the usual precautions when using scissors or a blade. When marking the insulation, be sure not to use a sharp pen that could damage the insulation. Check all measurements and markings before making any cuts. If unsure, cut your mats slightly large. You can always cut a little extra afterwards, but you can’t add extra back on.

Window Mat Insulation
Step 1: Measure the Insulation Against the Windows

Place the Low-E insulation against either the inside or outside of the window and mark the height and width of the window onto the insulation with a marker pen.

Step 2: Cut the Insulation

Put the insulation to your measurements. We suggest using something with a straight edge as a guide when cutting the insulation. Once cut, hold the insulation back up against the window to make sure it fits correctly.

Cut the Insulation

Step 3: Round the Corners

You can use scissors to round the corners of your window mats for a neater finish. Only a small piece needs removing to round the corners.

Round the corners

Step 4: Cut Holes for Suction Cups

Repeat the above process for all your windows. Once you have all the mats cut, mark a placement in all four corners for each of the suckers (in a minimum of 70mm from the edges). Cut a small piece from the insulation at each of the marked points (approx.. 10mm x 10mm).

Cut Holes for Suction Cups

Step 5: Fit the Suction Cups

Place the male part of the grommets through each hole and fit the suction cups to the female part, securing on the opposite side of the insulation.

Fit the Suction Cups

Step 6: Repeat for All Windows

Use care when taking down your window mats. If the insulation is forced or pulled the suction cups can pull through and tear the insulation. To remove, gently fold the insulation back from the corner and remove the suckers from the window with your finger.

Repeat for All Windows
