Insulation

Keep warm, save energy and help the environment with our efficient insulation products. From quality loft insulation to draught excluders that fit along door frames, there’s something to suit every property in our practical range. 

Our draught excluders are available in tape form for total control, or brush bottom strips for a heavy duty solution. Adding loft insulation to your attic space is so easy and can dramatically slash your energy bills. Use our pre-rolled insulation to effectively seal in the heat and add loft boards on top for extra space to store your belongings. You can also protect pipes from freezing and bursting with our insulated pipe covers and wraps. Pick up a roll of insulation tape to keep pipe lagging in place, and use electrical insulation tape if you’re dealing with wires. Browse all our insulating solutions and enjoy a cosy home all year round with Homebase.
