EXCELLENT Based on 1128 reviews D W2025-09-23Trustindex verifies that the original source of the review is Google. I ordered insulation boards and insulation rolls. The local roads are narrow farm tracks with restricted access so I checked delivery would be possible. A suitable delivery vehicle was assigned and the order arrived on time and as expected. Friendly driver, good communication with the customer service and a competitive price. Great service all round.

9 reviews for Kingspan Kooltherm K118 42.5mm Insulated Plasterboard (2400 x 1200mm) – 51.84m2 pallet
Question: |
Do insulated plasterboards cause damp? |
tradein |
Answer: |
Ensure insulated plasterboards are correctly fitted. This includes all gaps filled to prevent moisture moving from the warm air in the room to the colder solid wall behind the insulation. This will present a condensation risk which can cause mould and rot. |
|
Question: |
How do you cut an insulated plasterboard? |
tradein |
Answer: |
Firstly, measure and mark the insulated plasterboard to size. Secondly, place the board on a firm higher surface to allow the saw to cut through the board. Thirdly, cut with a fine-toothed saw for precise lines. |
