Care
Looking after your insulation and radiant barrier
These products sit out of sight, so there is very little to maintain. This page covers what to check once a year, what to keep clear, how to stay safe around them and when to call us.
Once a year
A simple yearly check
Look for daylight and gaps
Check that panels, seams and edges are still sealed and flat. Tape that has lifted or a panel that has slumped is worth a photo.
Look for moisture
Stains, damp patches or a musty smell can point to a roof or plumbing leak. Fix the leak first, then tell us if any material got wet.
Look for pests
Droppings, chewed edges or nesting material mean animals have found a way in. Close the entry point and call us if material is damaged.
Look for dust and debris
A heavy layer of dust on the foil face reduces how well a radiant barrier performs. Gently vacuum or brush it off when you check.
By product
What to know for each
Radiant barrier
Keep the foil face clean and clear of insulation or boxes lying on it, and keep air space in front of it. Do not paint it.
Double-bubble insulation
Check the seams and fixings. Avoid sharp objects that could puncture the sheet, and keep it away from open flames and hot flue pipes.
Garage door insulation
Open and close the door normally. Check that panels have not shifted, and wipe off dirt with a soft cloth and mild soap.
Garage attic insulation
Keep stored items off the material and do not walk across it. If you need access, use boards over the joists.
Do and do not
Do
- Keep a clear path to the attic hatch.
- Use boards when you need to walk in the attic.
- Keep foil faces clean and uncovered.
- Tell us before running new wires, ducts or lights through treated areas.
- Photograph anything that looks lifted, torn or wet.
Do not
- Pile boxes or loose insulation against a radiant barrier face.
- Staple, nail or cut into the material without checking with us.
- Use strong solvents or wet-clean foil.
- Block soffit and roof vents.
- Leave bare wires, recessed lights or flues touching the material.
Safety
A few things to know
Heat sources
Keep material clear of flues, recessed lights and any hot surface. Check the product label for clearances.
Electrical
Metallised foil conducts electricity. Do not let it touch live wires. Call an electrician before work near it.
Attic work
Attics get very hot in Texas summers. Work early in the day, use boards over joists and never step between joists.
Ventilation
Do not block vents. Good airflow keeps the attic dry and helps the radiant barrier work.
Normal and not normal
What is fine and what needs a call
Normal
- Light dust on the foil over time.
- Small wrinkles in the sheet that do not affect coverage.
- A slight rattle in strong wind on a loose garage panel, which we can adjust.
Contact us if you see
- Panels that have fallen, sagged or torn.
- Water stains or damp material.
- Pest damage or nests.
- Peeling tape or adhesive.
- A sudden rise in attic or garage temperature.

Care questions
Does a radiant barrier need cleaning?
Light dust is normal. If there is a heavy layer, brush or vacuum it gently. Do not wet-clean.
Can I store things in my attic?
Yes, but keep items off the foil face and off insulation so air can circulate. Use shelves or platforms where possible.
Can I add more insulation later?
Often yes, but keep loose insulation away from the radiant barrier face. Ask us first.
How long does it last?
The materials are designed to last for many years when kept dry and undamaged. Ask us for the warranty terms for each product.
What if the garage door insulation falls off?
Contact us with a photo. We will check the fixings and, if it is covered, fix or replace it.
Is it safe around wiring?
Foil is conductive, so keep it clear of live wires and have an electrician check any work near treated areas.
